A b s h n c b We evaluate several retransmission policies for transport protocols that support multihoming, such as SCTF'. We find that schemes that attempt to improve the chance of success by retransmitting to an alternate peer IP address often degrade performance. Our results show that for better performance, new data transmissions and retransmissions should be sent to the same peer IF' address. We also find that our Multiple Fast Retransmit algorithm further improves performance by reducing the number of timeouts. Since our results assume reachability of all peer IF' addresses, we conclude with suggestions for scenarios where failures are possible. We suggest compromising some of the performance improvements to avoid performance degradation during failures.
Caro et al. REF used the multiple fast retransmit algorithm as a retransmission strategy to reduce the number of timeouts to improve the performance.
