P2P (Peer to Peer) Opt Performance Measurement and Management for Two-Level Optimization of Networks and Peer-to-Peer Applications

(GR/S69009/01)

Aims

Funded by EPSRC, supported by UKERNA, P2POpt is focused on the measurement of network traffic patterns indicative of the onset of peer-to-peer application activity, the use of active measurement techniques to detect such onset in real time, the exploitation of these indications to re-engineer network traffic, and the symbiotic optimization of overlay network structure in parallel with such traffic re-engineering.

The overall research goals for the project are:

Correlate application-level and network-level traffic to detect network-level signatures that indicate onset of p2pactivity.
Use programmable network elements to implement always-on, active measurements of the network-level trafficto detect these patterns in real-time and trigger appropriate traffic engineering to ensure acceptable performance levels in the network.
Analyze the effect of the overlay network structure on the measured network-level traffic to drive optimizationof the overlay network structure.
Understand how to synergistically optimize programmable network and application level structures simultaneously.
