a surprising outcome
There are various ways of doing IP over ATM
- “Classical IP” MTU ~9K
- “LANE” MTU 1500 bytes (for Ethernet bridging)
Which would you expect would have better bulk TCP performance, and by how much?
Classical IP did better -- by a factor of ~5! I didn’t believe it at first.
Turned out that both were sending roughly the same packets/sec; CLIP: more bytes/packet
