Most people are using 64 bit counters. This avoids the wrapping problem (assuming you don't have 100GE and poll more then once every 5 years :-)).
2^64 is 18,446,744,073,709,551,616 bytes. 100 GE (100,000,000,000 bits/sec) is 12,500,000,000 bytes/sec. It would take 1,475,739,525 seconds, or 46.79 years for a counter wrap. -- Alex Rubenstein, AR97, K2AHR, alex@nac.net, latency, Al Reuben Net Access Corporation, 800-NET-ME-36, http://www.nac.net
