The Research of Loss Differentiation Algorithm in Heterogeneous Networks
异构网络中丢包识别研究综述

As the development of computer network, a single logical overlay network composed of many heterogeneous networks is becoming popular, The key difference of these networks is more loss event as channel characters changes frequently and loss cause is much more complicated than the single network. The traditional TCP protoeol is designed for wire circumstance and is evidently poor in such circumstance, Then it is becoming a hot area in heterogeneous networks to evaluate TCP protocol. Studying various TCP protocols, especially the key problem of loss differentiation, we summarize the general strategies for loss differentiation algorithm and analysis some kinds of approaches on loss differentiation. We then give the research directions of how to control losses and improve the TCP performance, which is necessary for further study on TCP improvement over heterogeneous networks.
