Stochastic Networks With Multipath Flow Control: Impact of Resource Pools on Flow-Level Performance and Network Congesti

Multipath flow control has been proposed as a key way to improve the Internet's performance, reliability, and flexibility in supporting changing loads. Yet, at this point, there are very few tools to quantify the performance benefits; particularly in the context of a stochastic network supporting best effort flows, e.g., file transfers and web browsing sessions, where the metric of interest is transfer delay. This paper's focus is on developing analysis tools to evaluate flow-level performance and to support network design when multipath bandwidth allocation is based on proportional fairness. To overcome the analytical intractability of such systems the authors study closely related multipath approximations based on insensitive allocations such as balanced fairness.
