Jet Infosystems develops an efficient traffic management system for the Higher School of Economics
Moscow. The Higher School of Economics and Jet Infosystems have developed a comprehensive system for dynamic Internet access management based on Jet Subscriber Manager (JSM) and Procera Networks PacketLogic (a DPI solution). HSE now has a tool to control crticial overloads and rule out network failures, increase the reliability of web applications, perform quantittavie and qualitative analysis of traffic structure and personalize network users.
“Our largest site is the Moscow campus that includes school premises, administrative buildings, some dormitories in the Odintsovo area (about 30 km from Moscow) and some in the city. Students and staff can access the Internet from any of these buildings, - tells Oleg Scherbakov, head of HSE IT department. – We believe that our users should enjoy guaranteed quality of access not just to the Web but also to web services. This, however, requires some kind of traffic management, especially in dorms, where each of the 6.5 thousand users takes advantage of three or more services. It is easy to imagine what happens to the bandwidth during peak hours when most students come home from school. To control the situation one needs an instrument for personal authorization, high-quality traffic analysis, the application of appropriate policies (including restrictions) and fair bandwidth allocation. It was also necessary to enhance corporate network security to foil insider attacks."
At the first stage the system was deployed for two principal internet access channels in academic and administrative buildings, and one channel covering three dormitories in Odintsovo. The project took about 3 months to complete. Jet Info engineers developed a set of network operation rules, tested and set up the DPI hardware, successively assembled each of the nodes, deployed JSM on the virtual infrastructure of the university and set up traffic management policies.
“DPI gives network administrators an opportunity to see traffic structure, generate regular reports on bandwidth consumption and forecast this consumption as well as identify upgrade needs. However, we wanted more than a simple “demonstration” of traffic content. For deeper analysis and further elaboration of rules for differentiated traffic management the analysis had to go down to individual users,” - explains Elena Fominskaya, director of the Telecommunications Products and Solutions Center, Jet Infosystems.
During the project JSM was integrated with the corporate Active Directory for staff access and AD Office 365 for students. Accordingly, personal traffic could be identified for all HSE network end users. A service was also deployed that guarantees dynamic priority access to wi-fi bandwidth, services and resources (e.g. for training, seminars or conferences) on request.
Jet Infosystems engineers provided extensive training for HSE network administrators that included a demonstration of various scenarios typical of the university.
The system has been working on a full scale and accumulating statistics for over half a year (since February 2015). The personification feature has been launched in administrative buldings, where networks with unrestricted access are being decommissioned. Unrestricted access in dormories will be deactivated in the near future.
“Traffic management in “student” networks is an established internation practice now. In the project for HSE we have used our best experience and once again have successfully coperated with a Jet Infosystems’ PCRF class product,” – notes Anton Degtiarev, EMEA pre-sales manager, Procera Networks.
The university is planning to extend dynamic traffic management to all its buildings in Moscow. The system may also be successfully reproduced at its campuses in other cities, probably with a broader application of DPI and JSM.
The Higher School of Economics (HSE) is a national university established in 1992. Today it offers education in many fields apart from economics and sociology. Its staff consists of leading economists, sociologicsts, historians, philologists, linguists, mathematicians, physicists, engineers, designers and IT experts. Education levels at HSE range from high school to graduate school. HSE runs 59 baccalaurate programs, 113 magister programs, 13 graduate schools as well as continuous education and business education programs. It also operates over 100 research centers and about 20 international laboratories headed by leading foreign scholars including several Nobel Prize and Fields’ medal winners.
