A key challenge for ISPs is to characterise and predict the impact of traditional TCP-based services
on the user experience quality of emerging VoIP and IP video services in the broadband consumer
space. A related challenge is to predict and understand how the growth of highly interactive online
environments (such as real-time multiplayer games) will impact on, and be impacted by, VoIP, IP
video and traditional TCP-based applications.
Building on previous work at CAIA under the GENIUS and SONG
project, we aim to development traffic generator tools and empirically proven models
of large scale consumer broadband traffic.
- Develop and release deployable open-source tools for traffic synthesis and generation.
- Extend theoretical work  on synthesis of game traffic for N-player scenarios.
- Provide empirically verified models for queue sizing (in broadband routers and modems), TCP congestion control algorithms, game and VoIP traffic interactions that create dynamic latency fluctuations experienced by all traffic usnig a given broadband link.
- Provide updated/new documentation as appropriate for all developed tools.
