Description

  • Content Description: This paper discusses the performance testing experiences of a 622.08 Mbps OC12 link. The link will be used for large bulk data transfer, and as such, of interest are both the ATM level throughput rates and end-to-end TCP/IP throughput rates. Tests were done to evaluate the ATM switches, the IP routers, the end hosts, as well as the underlying ATM service provided by the carrier. A low level of cell loss, (resulting in <.01 % packet loss), decreased the TCP throughput rate considerably when one TCP flow was trying to use the entire OC12 bandwidth. Identifying and correcting cell loss in the network proved to be extremely difficult. TCP Selective Acknowledgement (SACK) improved performance dramatically, and the maximum throughput rate increased from 300 Mbps to 400 Mbps. The effects of TCP slow start on performance at OC12 rates are also examined, and found to be insignificant for very large file transfers (e.g., for a 10 GB file). Finally, a history of TCP performance over high-speed networks is presented.
