Operational Environment
Multi-Gbit SuperJANET connects multi-Gbit Regional Area Networks
Regional networks connect Colleges, universities, other organisations.
Over 150 Universities Over 600 Colleges Many Research Institutions Links range from 10Mbits/s (Colleges) – Gbits/s (Universities)
An abundance of bandwidth on most university campus networks Not so on many college campus networks.
Bandwidth Management Advisory Service
Problems
Many unwanted protocols, some illegal on both university and college campuses.
Critical link and segment congestion, especially on college campus networks.
Solutions Evaluation of effectiveness of several products applied to
time critical streaming services, namely: Packeteer PacketShaper, Allot NetEnforcer, Cisco NBAR
Deployment of Packeteer campus production environment
Bandwidth Management Advisory Service
JANET-BMAS Streaming Trials
Aim Ability to promote time critical data (video streaming)
and throttle non-time critical data (HTTP, FTP)
Products/Solutions tested Packeteer PacketShaper, Allot NetEnforcer, Cisco
NBAR
Conclusions drawn from technical results and human perception of quality of service

PacketShaper at The University of Manchester
Location:
Uses P2P restriction Virus propagation Anti-DDoS Blocking internal non-sanctioned HTTP/FTP servers
Bandwidth Management Advisory Service
PacketShaper Advanced Features
Top Talkers/Listeners Identify bandwidth hogs
PacketCapture Identify non-sanctioned network uses Beware of legal implications
Adaptive Respond Let the box adapt to network conditions before you
even know about them Custom Classes
Adapt the PacketShaper to your exact requirements
Bandwidth Management Advisory Service
Conclusions
Future work Bandwidth will increase
…but so will bandwidth hungry applications More and more demand for time-critical services
VoIP Video Streaming Remote Collaboration Video Conferencing
JANET-BMAS ending but the need for bandwidth management will continue
