This draft addresses an IP-based solution to the problem of high system costs due to network I/O copying in end-hosts at high speeds. The problem is due to the high cost of memory bandwidth, and it can be substantially improved using 'copy avoidance.' The high overhead has prevented TCP/IP from being used as an interconnection network.
