Plan of Attack
1. Find some flexible high-speed network interfaces.
Myricom LANai-4/5/7 with Trapeze firmware
(and Alteon Tigon-II Gigabit Ethernet)
2. Extend a public-domain Unix kernel with high-speed networking optimizations known in the literature.
FreeBSD 4.0...
...extended for zero-copy sockets and checksum offloading.
3. Use netperf to benchmark TCP/IP on different configurations, using iprobe to profile host CPU activity.
2 types of PCs and 2 types of Alphas
32- and 64-bit PCI
vary MTUs from 1500 bytes up to 32KB
