TCP includes several mechanisms that attempt to sustain good data

transfer rates while avoiding placing excessive load on the

network. TCP's "Slow Start", "Congestion Avoidance", "Fast

Retransmit" and "Fast Recovery" algorithms are summarised in RFC

2001. TCP also mandates an algorithm that avoids "Silly Window

Syndrome" (SWS), an undesirable condition that results in very

small chunks of data being transferred between sender and

receiver. SWS Avoidance is discussed in RFC 813. The "Nagle

Algorithm", which prevents the sending side of TCP from flooding

the network with a train of small frames, is described in RFC

896.
