Bandwidth Allocation in TCP Friendliness and P2P Streaming

  • Lisong Xu | University of Nebraska-Lincoln

In this talk, I will talk about our recent work on bandwidth allocation problem in two projects: TCP friendliness and P2P streaming.

  1. Exploring the design space of TCP-friendly traffic control protocols:

While the current definition of TCP friendliness has enabled a wide variety of traffic control protocols other than TCP, it still considerably restricts the design space of TCP friendly traffic control protocols. In this project, we propose a new class of TCP friendliness definitions, called Stochastic TCP Friendliness, which greatly expands the design space of TCP-friendly traffic control protocols, while still effectively maintaining the desired stability and fairness of the Internet.

  1. Exploring the design space of multi-channel P2P streaming systems:

Most of the commercial P2P streaming systems support hundreds of channels and are referred to as multi-channel P2P streaming systems. Recent research studies have proposed several bandwidth allocation methods to improve the system streaming quality by enabling cross-channel cooperation. In this project, we study a fundamental problem: which bandwidth allocation method can achieve the desired streaming quality with the lowest implementation complexity?
