Explain How does TCP try to avoid network meltdown?

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.
