Executive Summary

A multi-homed NEtwork MObility (NEMO) architecture has been proposed previously to improve the reliability and aggregate the bandwidth of Mobile Router (MR) by simultaneously using multiple wireless links. In this paper, the authors discuss some potential issues that could affect the performance of TCP traffic in a multi-homed architecture. In addition, they propose a protocol to improve the performance of sending a single TCP connection over multiple wireless links on a MR. They evaluate the performance of their protocol by comparing it with the Concurrent Multi-path Transfer SCTP (CMT-SCTP) and show that it can resolve several performance issues.
