Allot

Managing University Campus Network Resources
Describes how the NetEnforcer can prevent network abuse and ensure access to network resources for university faculty members and administrators.

The Problem:
Students overloading network resources (WAN connection, Cache, servers) with superfluous traffic (such as audio files). Faculty and administration suffer from reduced available bandwidth and higher response time. Critical applications (like SAP) users are experiencing unpredictable performance.

The Solution:
Limit the use of lower priority traffic with the Allot Communications NetEnforcer®. Assign Quality of Service for each user group, for students a limited access during business hours, and for Faculty members or administration high priority access to network resources

The Environment
With the growing popularity of applications like Napster (sharing music files), more bandwidth is used for non-business purposes, while critical applications (like ERP) suffer long delays. New multimedia rich applications like distance learning and web traffic of threaded newsgroups are demanding a wider bandwidth and low jitter for stable picture and clear sound. Adding bandwidth does not solve the problem. More available bandwidth is "swallowed" by new traffic rapidly. In the lack of QoS, downloading of (music) files will consume any available bandwidth. University campus network managers face the following issues: How to assign the minimum bandwidth necessary to critical applications How to prevent non-critical traffic from overloading the already stretched bandwidth How to avoid abuse of campus computers and block illegal use of CPU to attack other .com sites (e.g. Denial-of-Service attack)
