This is the part about TCP that I've never understood: why does it send large numbers of packets back-to-back? This is almost never a good idea.
Because until you congest the network to the point of dropping packets, a host has no idea how much bw is actually available. Exponential rate growith finds this value very quickly.
Hm, I don't see this happening to a usable degree as TCP has no concept of records. You really want to use fixed size chunks of information here rather than pretending everything's a stream.
A record-oriented, reliable transport would make many protocols much easier to implement. Too bad SCTP hasn't seen wider use.
