This talk is concerned with providing low priority data transfer across wide-area networks. Although this is straightforward when the underlying network supports service differentiation, it becomes more challenging without such network support. We will describe an application level approach to providing such service differentiation in the current Internet, solely based on receivers adapting their receive window. This approach is motivated and analysed using fluid flow models and a utility maximization framework, which allows us to identify resulting rate allocations, and asymptotic stability, for candidate adaptation strategies.

This is a joint work with Peter Key and Bing Wang.
