Analysis of TCP Parallelization over Wireless Links

Inhalt:
TCP parallelization uses a set of parallel TCP connections to transfer data for an application process. It can achieve a high throughput more quickly than a single connection and is less sensitive to transient/random packet losses or congestion. Along with other features, this makes the approach viable in lossy wireless networks, especially the emerging highspeed wireless networks where the top speed may never be reached by using a standard TCP connection. However, there is a lack of research efforts to explore the potential of TCP parallelization in wireless environments. In this paper, we present a general analysis of TCP parallelization in wireless environments without focusing on a specific wireless system. The analysis shows that TCP parallelization is capable of reducing the cost of losses on wireless links and can be a fundamental step towards improvement of the TCP performance in heterogeneous networks.
