Congestion Avoidance

Assumption : If we are to deal with pure technique on how tcp reacts for congestion we assume things that packets are lost not because of faluts ; packets are lost because of congestion itself

as we know that congestion windows gradually increases with increments of 1MSS from previous post or the other way to deal with increments of packets are


once we hit threshold windows size drops to 50% of its present value and again the process continues

Let us say a packet encountered congestion at 10000 bytes of data . now it drops back to 50% therefore the present size would 5000 bytes and process continues
