  • Wired - Prepare thirty-five of the campus residence hall’s cable plant for an upgraded wired access infrastructure which will, when combined with upgraded network electronics, provides students up to 1000 Mbps Ethernet service.
  • Wireless - Installation of over 1800 Wireless Access Point devices in thirty-four residence halls to provide wall-to-wall wireless services of up to 850 Mbps.
  • Emergency Phones - Installation of cable plant and devices to provide over two hundred emergency phones which allow for a direct line of communication to campus emergency dispatch.

Fiber upgrade for DSL Buildings - To support decommissioning of the legacy DSL (digital subscriber line) service in the fall of 2014, NI&S outside plant crews and network engineers collaboratively designed and installed new fiber optic cabling in twenty-two outlying campus buildings.  The new connectivity allows these buildings to connect to the campus network at the same network speeds as other university buildings.  

University Computing Support

Service Now - In September 2014, Virginia Tech Information Technology Support replaced their Helpdesk incident management system with ServiceNow, an enterprise-wide cloud-based Information Technology Service Management (ITSM) solution. Over the next several months, other IT units interested in developing an ITIL-based service strategy began using ServiceNow.

Service Catalog - New capabilities offered through the implementation of ServiceNow spawned interest across IT in the development an organization-wide service catalogue/service portfolio. A multi-pronged effort to conceptualize and populate an IT Portfolio/Service Catalog, using an ITIL based approach, was launched to begin efforts to develop an IT-wide portfolio of services. Led by Claire Gilbert, the Director for Strategy & Analysis for the Office of the Vice President for IT & CIO, a pilot group of four of IT’s largest groups– (Network Infrastructure and Services (NI&S), Enterprise Systems, Technology-enhanced Learning and Online Strategies and Identity Management Services was initially established to begin work on the first Phase of the Service Catalog.  Project work was divided into three (3) specific tracks that focused on: 1) developing pilot documentation of these four units’ IT services, 2) designing the look and feel of the catalog and 3) implementing the Service Catalog.

The pilot group was later expanded to include all central IT units in order to provide an opportunity for all public facing services to be included in the first iteration of the Service Catalog.  UCS staff members (Kimberly Homer, Kevin Davis, Anne Sheppard and Graduate Assistant Allison Homer) participated as Project Team members in conjunction with other central IT staff members to work on Track 1 and Track 2 initiatives throughout the year. From December 2014 to May 2015, work completed on Track 1 included the development of a finely detailed “Master Matrix of Services” that included over 100 university information technology services and hundreds of subservices. The matrix provided a way for each service to be thoroughly documented so the project team could determine, along with the Service Owner, if the service should be included in the Service Catalog. Work on Track 1 also included consultation with a peer university with a fully established Service Catalog to obtain advice on the creation and implementation of Virginia Tech’s Service Catalog.

Work on Track 2 focused on the design of the Service Catalog and was completed during the same time frame. Track 2 included significant research in order to reach the goal of creating a highly accessible and aesthetically pleasing catalog. A Categorization Study of over fifty university service catalogs was completed to better understand how other universities identified service categories. A statistical analysis was then completed on the Categorization Study to determine the mean, median, mode, maximum, and minimum number of categories used. Next, Service Catalog benchmarking was completed by analyzing nearly 100 service catalogs based on ITIL recommendations and usability guidelines. Project team members analyzed the benchmarking and key design recommendations and preferences were discussed in detail. Key recommendations were then captured and summarized to inform the development, design and implementation of the Service Catalog. The culmination of this work was the successful launch of the first iteration of Virginia Tech’s Service Catalog.

BigFix/Patch Management for Departmental IT and RLAN _- The Information Technology Security Office (ITSO) and University Computing Support (UCS) staff collaborated to support a system capable of patching desktop operating systems and third-party software on machines in both the Restricted-Limited Access Network (RLAN) and traditional department network environments. Since implementation of IBM’s Endpoint Manager (BigFix), there are more than 3300 machines in over 16 departments benefiting from the solution.

IBM’s Endpoint Manager (BigFix) has functioned as a cost-effective solution that is scalable in Virginia Tech’s environment. It allows departments to control their own patching, with little required maintenance. System and performance milestones for the period: 

  • Virtual Server is performing nearly at capacity
  • Plans are being implemented to obtain a new physical server 
  • Client licenses quickly consumed all initially procured licenses; a survey of enrolled departments and other departments interested in enrolling indicates a potential of 3,500 to 4000 potential new clients
  • Restricted Limited Access Network machines are performing well
  • To address compromised systems on campus, several analyses were combined into one Windows analysis to check for multiple potential attach vectors
  • Analyses are being developed to check for similar vectors for Linux and Mac operating systems.

ACC Computer Ordering/Delivery improvements - Over 300 computers were successfully purchased then distributed to eligible E&G funded employees throughout the university community. The process of scanning machines was streamlined this year to help automate and make the issuing process more efficient.

Fall Move-In Computing Support - As students moved in and started their first week of classes for the fall 2014 semester, the 4Help Helpdesk and the Get Connected Program collaboratively provided convenient walk-in computing support at the Newman Library Multipurpose Room. 4Help consultants and Get Connected staff, along with full-time University Computing Support (UCS) staff, provided phone and email support to nearly 1400 students, as well as in-person support for approximately 1100 cases. To encourage students to set up their own devices, 4Help developed a “Computing 101” website, where students choose their major and operating system. The site then generated a sequence of instructions specifically tailored to assist students with setting up their devices. A Parallels virtual machine was created to quickly address needs for using Windows on a Mac and, building on the successful results of last year, 4Help-led Boot Camp sessions. In the technical support room, relevant videos from our HokieHowTo channel (www.youtube.com/hokiehowto) were played on a loop to encourage people in our waiting area to attempt to resolve their device issues.

Get Connected Program - In addition to collaborating with the 4Help Helpdesk, individual Get Connected (GC) staff were assigned and dispatched to specific residence hall quads to troubleshoot, set up, and configure new residence hall students’ computers, mobile devices, and routers during move-in. Since routers were permitted to be used in residence hall rooms, a generic router setup video was created in preparation for Get Connected. In 2014, the top three issues that GC staff resolved were routers, printers, and connections to the university’s wireless network. GC staff handled 158 router setups, 108 printer setups, and configuration of wireless connections in 77 cases. In addition to these major issues, staff assisted with installing Microsoft Office on Mac and Windows computers, connecting devices to the Ethernet, setting up televisions, assisting with installs of the student software bundles, and setting up Parallels (adding a Windows operating system to a Mac). Staff also marketed 4Help staff services by, leaving business cards with 4Help’s phone number and website with every student they worked with. In addition, they hung door hangtags on each resident’s door directing users to computing self-help resources, as well as informing residents of other ways to get assistance. During the four days of move-in and while assisting the Corps of Cadets, 29 GC staff provided in-person computing assistance to 504 students in the residence halls.

Gobblerfest - In a third year of collaboration, ITSO and 4Help operated a booth at Gobblerfest (a festival to welcome students, staff, faculty, and community members in the early fall) to market 4Help’s services and share information about how to stay safe on the Internet. Topics included recognizing and avoiding phishing attempts, never sharing one’s password, and using social media thoughtfully. As in years past, large crowds of students are engaged by playing a game of Plinko or spinning a wheel to win prizes. Representatives from ITSO and 4Help distributed informational material and talked with students about computing security. Plinko and spin the wheel contain game inserts for cases when the student loses the game—typically along the lines of “Got phished, try again!” or “Downloaded malware, spin again,” which encourages contextual conversation with the student about what it means to be phished or to download malware. Promotional items directed students to ITSO’s security awareness website (http://www.awareness.security.vt.edu/) to learn more about securing their computer and staying safe on the Internet.

Goobler Fest4Help also marketed their Twitter account, @4HelpTweets at Gobblerfest. In an effort to heighten interest and increase participation, followers were provided with computing tips and information about computing services, as well as opportunities to retweet important IT information for a chance to win prizes.

Cyber Security Promotion and Staff Appreciation Day 2015 - Cyber security safety was promoted during October, Cyber Security Awareness Month, with a crossword puzzle that contained many questions and answers on the topic of computer security. Students submitted their completed crosswords to our Twitter account and, if the crossword was correct, the students were entered into a random drawing for a prize. In completing the puzzle, participants learned about smart security practices.

On May 20, 2015, 4Help and ITSO staff teamed up again to provide Cyber Security information as a part of two games for Staff Appreciation Day. As with Gobblerfest, the games drew large crowds and invited discussion about being secure on the Internet and not being fooled by phishing emails. Prizes that were distributed directed staff both to security and technical support resources.

4HelpTweets - In its third year, the @4HelpTweets Twitter account grew from 600 to 1000 followers after being advertised at New Student Orientation, as well as being retweeted by other major Virginia Tech Twitter accounts. Originally intended to reach incoming freshmen, the account continues its momentum in gaining followers from departments, student organizations, and members of the IT community. 4Help staff use the account to tweet and retweet IT-related events as well as university-specific information, especially in conjunction with @VT_NIS (our department’s account). Information about computing at Virginia Tech or interesting technological information is shared with the campus community when pertinent, though the account tweets on a weekly basis. Users’ questions are responded to via Twitter and are often relayed by other university Twitter accounts. 4HelpTweets continues to award prizes for retweeting pertinent IT information, especially during the week of move-in and Gobblerfest. 

Wintermester - During December 2014, Virginia Tech held the second year of a special academic Winter Session between the fall and spring terms. Referred to as Wintermester, the session is designed to augment students’ progress toward fulfilling their degree requirements and also provides participants with the opportunity to get ahead in coursework, fulfill a course requirement or explore a new area of interest. Visiting students were able to experience Virginia Tech scholarly offerings in an abbreviated time-period.  Close to 2000 students took part in studies of 128 courses offered in four settings:

  • Virtual – 100% online.
  • Blended – Combination of online and in classroom.
  • Winter Experience – Study abroad courses are offered internationally and domestically. 
  • On-campus – Course offered on the Blacksburg campus.

University Computing Support and the Virginia Tech Operations Center (VTOC) made special provisions during a period the university is otherwise shut down to provide increased consulting support and services in collaboration with our IT service partners (e.g. Technology-enhanced Learning and Online Strategies). Participating students, faculty and staff benefited from a comprehensive list of additional support measures and exclusive escalation paths which enabled customer support representatives and Information Technology consultants to promptly transfer problem report tickets to the appropriate service partner.

Diversity Allies - NI&S employees are committed to practicing Virginia Tech’s Principles of Community—creating an environment that fosters a diverse and inclusive community and supports mutual respect and understanding of all individuals. Several staff members completed courses offered by the university’s Diversity Development Institute. These courses allowed attendees to explore differing attitudes, to use and advance inclusive language and behavior, and to gain a better understanding of the complexities of identity. University Computing Support staff member Amanda Cooper and VTOC Supervisor Brian D. Jones received their Diversity Ally Certificates. UCS staff members Anne Sheppard and Joyce Landreth earned their Diversity Advocate Certificates.

Web Software Development

Network Management Application -   The Network Management Application (NMA) was developed to provide capabilities for viewing building nomenclature, network data traffic and to assess the status of network devices and device classes. The NMA’s improved accuracy and efficiency increased productivity of NI&S’s network engineers. The application is used primarily by Converged Network Operations, Research & Development, and Virginia Tech Operations Center teams.

Customer OnLine Access & Guest web portals - Web Software Development group moved the Customer OnLine Access and guest portals off old servers and onto new equipment, while maintaining existing applications and applying software patches and updates. As a result, systems availability met or exceeded objectives.

ATLAS Support for Residential Network Upgrade

During summer 2015, a large-scale project brought comprehensive, high-performance, Ethernet, wireless network coverage and special Emergency Phones to Virginia Tech’s residence halls.

Network Infrastructure and Services’ ATLAS system team provided critical data analysis, application development and modification, and extensive order-processing automation behind-the-scenes to ensure these important upgrades for all residence halls were completed during the summer months.

Bringing wireless coverage to the residence halls included the design, planning, and installation of approximately 1,800 wireless access points (WAPs) in 34 residential buildings on campus, along with the upgrade of all Ethernet access switches that furnish power and connections to Virginia Tech’s computing network.

The wireless network upgrade used technology designed to support speeds up to 850Mbps in all residence hall rooms along with a single, wired, 1 Gbps Ethernet connection per room.  Lounges and many other public areas with seating also now have wireless coverage.  

Customer Support Services

Account Representatives with Customer Support Services (CSS) worked as advisors with major departments, including but not limited to the College of Engineering, College of Agriculture and Life Sciences, College of Science, Virginia Tech Transportation Institute, and collaborated successfully on their communications projects.

During the report period, building infrastructure updates continued, re-cabling active services to meet the Unified Communications standard.  More than 3,100 orders were written to install voice-over-IP equipment for customers in nine buildings. 

  • Pamplin Hall
  • Burruss Hall
  • Southgate Center
  • Wallace Hall
  • New Hall West
  • Ambler Johnston
  • Roanoke Street Partnership
  • Building 1861
  • Graduate Life Center

Customer Support Services provided customer engagement, internal support and customer work order support for the following projects:

  • Indoor Athletics Training Facility
  • Marching Virginians Pavilion
  • New Classroom Building
  • Pearson Hall
  • Residential Network Upgrade Wireless Access
  • Residential Network Upgrade Wired Access
  • Residential Network Upgrade Aggregation Network
  • Cheatham Computer Re-cable
  • Campus Cameras 2015
  • South Recreation Fields
  • Equine Medical Center Network Upgrade

Developing and Evaluating Emerging Technologies

Following are summaries of key projects under review.

MARIA 100G - Accelerating Science for All Virginia Universities - The reliable, predictable, and rapid dissemination of scientific data from its source, to innovators, scientists, and collaborators, is a challenge the “Campus Cyberinfrastructure-Network Infrastructure and Engineering” program seeks to address. Without world-class network infrastructure, the ability of institutions to conduct world-class research is hindered.

MARIA 100G addresses a known bottleneck in the NatCap network aggregation facility operated by Virginia Tech on behalf of the Mid-Atlantic Research Infrastructure Alliance research and education community in Virginia. The aggregation link to the Internet2 national research network is being upgraded from a 2x5 gigabit per second capacity to a 100 gigabit per second capacity, which paves the way for the unimpeded exchange of dramatically growing data sets in the course of scientific discovery. Hardware has been purchased, installed, and configured.  

Towards a Session Layer for the TCP/IP Protocol Suite - Contemporary applications demand greater functionality from the network than was required when the TCP/IP protocol suite was developed. This ongoing study is based on the premise it is not only possible to extend TCP/IP to achieve the necessary functionality, but also highly desirable as a means of easing the transition to the new functionality.

This year’s investigations have focused on developing a notion of a communication context and have looked at the benefit of applications having a "context manager." In particular, work has focused on supporting virtual machine migration across wide-area networks and on the performance improvement that comes from segmenting an end-to-end connection to allow TCP's control algorithms to work more quickly. The studies have demonstrated the efficacy of the approach by deploying new functionality without sacrificing backwards compatibility.

The Quilt - The Quilt continues to provide a dynamic forum where leaders from throughout the advanced research and education network community build on the intellectual capital and best practices of network service providers worldwide. As a founding member of The Quilt, Virginia Tech represents the Commonwealth via NetworkVirginia, the Mid-Atlantic Research Infrastructure Alliance (MARIA), Inc., and the Mid-Atlantic Research and Education Exchange (MREX) programs. The university realizes deep volume discounts from the national aggregation of Internet capacity using Quilt contracts for commodity Internet service.

Figure #3 – Wireless users on April 15, 2015

Trend analysis of a typical day shows heavy utilization of the service, peaking at over 23,000 users during the middle of the academic day. This usage represents a 30 percent increase over a typical day in 2014. Small dips throughout the day coincide with breaks between classroom periods. This pattern suggests that portable and mobile devices are heavily utilized by the student population during lecture and lab periods on a typical day when classes are in session.

 

Figure #4 – Aggregate bandwidth on April 15, 2015

The aggregate bandwidth on the university’s wireless network is depicted over a 24-hour time period. Bits per second out represents the amount of bandwidth that the wireless users consumed (downloaded); Bits per second in represents the amount of bandwidth generated by the wireless users (uploaded).  The amount of traffic uploaded by wireless users increased 12% from last year’s average.  The average amount of traffic downloaded increased by 31%. Note that the heaviest use is during the late afternoon and into the early evening.

 

 

Systems Support

Figure #5 – Network Storage (Terabytes)

The SAN and Network-Attached Storage (NAS) support Network Infrastructure & Services’ Virtualization, Unified Communications project, Enterprise Systems Database and Application projects, the safety and security camera project, System Development and Administration projects and Technology-enhanced Learning and Online Strategies projects.

The NAS also provides file level storage to support faculty/staff personal and departmental shares.

Figure #6 – Network backup/archive storage (Terabytes)

This graph illustrates the amount of data stored on the centrally managed backup service (disks and tapes). The total data storage on the centrally managed backup service (disk and tapes) for FY 14-15 dropped to 800TB due to departments’ increasing use of cloud-based back up services.

 

Figure #7 – Document Migration Facility (Terabytes)

Virginia Tech in research data analysis and storage systems support the university’s data intensive science programs, especially those at the Virginia Tech Transportation Institute and the Virginia Bioinformatics Institute, as well as the university's Advanced Research Computing environments. These systems include a research data archive based on SGI's Data Migration Facility (DMF) with several petabytes of capacity.

The research data archive continues to allow Virginia Tech's scientific data assets to be maintained throughout the anticipated research lifecycle, potentially over decades of continued scientific research, and is anticipated to scale to over ten petabytes in the foreseeable future. The DMF service requirements from the non-research community continue to grow.

 

Virginia Tech Operations Center

Figure #8 – VTOC Tickets (Incidents) by Configuration Item

In fiscal year 2014-2015, the Virginia Tech Operations Center (VTOC) replaced its Remedy ticketing system with the ServiceNow platform. This resulted in major differences in the way data is stored and handled regarding “incidents” (previously “tickets”). It has rendered the Remedy data and the ServiceNow data incomparable. However, the switch has made it possible to gather more detailed data than was available in the Remedy ticketing system.

The quantity for each of several categories of problem tickets or Incidents tracked during the period is illustrated as a “configuration item” in ServiceNow.” The number of tickets received for a variety of configuration items is displayed above.

 

Figure #9 - Total VTOC Calls with Incidents Reported and Resolved

Calls received by the Virginia Tech Operations Center (VTOC) are contrasted with the number of Tickets or Incidents logged, along with the number of Incidents resolved by VTOC consultants.

VTOC technicians receive questions and problem reports or incidents from constituents, then provide information and technical assistance. Tickets or Incidents are created, then resolved if at all possible. If the problems cannot be resolved due to a need for additional data or a higher level of technical expertise, the incidents are escalated to University Computing Support or other appropriate unit.

The multi-year trend of a decrease in Total calls received and the number of problem reports entered and resolved continued.

University Computing Support

Figure #10 - Help Desk incidents by Configuration Item

In fiscal year 2014-2015, University Computing Support replaced its Remedy ticketing system with the ServiceNow platform. This resulted in major differences in the way data is stored and handled regarding “incidents” (previously “tickets”). It has rendered the Remedy data and the ServiceNow data incomparable. However, the switch has made it possible to gather more granular data than was available in the Remedy ticketing system.

During the year, the Help Desk handled approximately 6441 incidents. These incidents, tracked as Configuration Items, are broken down above. The Help Desk worked mostly on incidents related to Virginia Tech’s new learning management system, Scholar, followed by providing General Information, then VT Google Apps Mail support. General Information consisted mostly of referrals (such as to vendors for hardware problems or non-ServiceNow partners) and answers to business or procedural questions. VT Google Apps Mail is the third most common Configuration Item due to emails being blocked, deliveries being delayed, or email clients (such as Outlook) encountering problems. Much time is spent on email-related issues because email is a vital business function used daily by faculty, staff, students, and alumni. Much of the university community prefers to use an email client instead of the web interface, which tends to yield more inquiries due to caching of information on the client, software problems, password changes while the client is running, and other dependencies which web-based email interfaces tend to avoid. This is the reason that the Help Desk encourages the use of the web interface for emails. The email inquiries also correlate with the high numbers for the Exchange, Outlook, and Mail Blocks Configuration Items.

                       

Figure #11 - Incidents per Assignment Group

In ServiceNow, the Help Desk works with many other groups to address user issues. The number of incidents assigned to each of these partners or groups is shown above. Most of the incidents in partners’ queues (except the Call Center and ABUSE) are first received at the Help Desk, then escalated. Consequently, the numbers for most of the assignment groups above were initially in the Help Desk queue and then transferred.

The numbers above represent the incidents assigned to a specific partnering group, but Desktop Support handles both tier 1 (Help Desk) and tier 2 (Desktop Support) incidents. Factoring those in, Desktop Support handled 392 incidents combined. Another part of the Desktop Support function is IT support for NI&S, and this group worked on 288 incidents.

University Computing Support, along with Information Technology Acquisitions, provided walk-in support on Torgersen Bridge through the Software Assistance & Education Center from the beginning of the fall 2014 semester. In November, due to water damage to Torgersen Bridge, the Software Assistance & Education Center program was discontinued. From that point, walk-ins were served at the University Computing Support mall location. A search was quickly initiated to find a new space for providing on-campus walk-in support.

 

Figure #12 – Most-viewed HokieHowTo self-service videos

 

University Computing Support (UCS) continued to develop its self-service support model so that resourceful users can independently find answers to frequently-asked questions or obtain assistance with many computer tasks day or night.

 

One of UCS’s most effective self-service resources is the HokieHowTo YouTube channel. The channel (www.youtube.com/hokiehowto) has grown as the UCS Knowledge Base group continues to add new videos, and apply updates to existing videos.

 

The three most-viewed videos were Installing Junos Pulse VPN on Windows 8, Sharing an Exchange Calendar in Outlook, and the Basic Phone Guide for the Avaya 9611G phones. A tally of total minutes watched and a total of discrete views of these and other most-viewed videos are depicted above.

 

The HokieHowTo channel had 21,294 views—an increase of 16% compared to fiscal year 2013-2014. This coincided with an increase in watch time, resulting in 23,546 minutes of video watched—a 12% increase from the previous fiscal year.

 

Business Operations

 
Figure #13 - Services Activity

The graph illustrates, by fiscal year, the number of active services currently billed to customers, alongside the number of service activations, deactivations, and changes for each year.

Active Services. The deactivation of ROLM legacy voice and data services, along with activation of Unified Communications voice and data services and Remote Access-VPN services resulted in a net decrease in currently active services.

Service activations, deactivations, and services changes. The number of service activations, deactivations, and changes represents the volume of customers’ requests during the year to move, add, or change NI&S services. These changes are often a result of departmental moves to new or renovated office space and the resulting domino effect when another department relocates to the space previously vacated. The decrease in service activations, deactivations, and changes in FY 2015 as compared to FY 2014 is attributed to the net of the deactivation of the ROLM legacy voice and data services and the activation of the Unified Communications voice and data services.



Administrative Support and Communications

 

Figure #14 – Internet Copyright Infringement Complaints (ICIC)

The volume of cases received during fiscal year 2014-2015 increased (+14%) compared to the prior year.

Irdeto continues to be the major source of Internet copyright infringement allegations (433 cases/58% of total) directed to Virginia Tech.

The Copyright Enforcement Group (CEG), LLC, is another significant source. The CEG, which “offers” to preempt legal action by settling out of court for a sum less than a “probable” court assessment, continued to increase their generation of cases, accounting for a 13% gain in cases this year. CEG cases differ from the typical infringement complaint, which complies with the Digital Millennium Copyright Act, by threatening court action before allowing the implicated party to curtail uploading of copyrighted files.
