General Overview Congestion Control mechanisms of old TCP was

Summary: General Overview
Congestion Control mechanisms of old TCP was
inadequate for the rapidly growing Internet. A
bottom-up rethink of the policies were needed in
order to adapt the TCP stack, in an effort to
make congestion the exception rather than a
common case scenario.
The main observation around which the
solutions presented in this paper was the "packet
conservation" principle - "for a connection in
equilibrium, a new packet shouldn't enter the
network before the old packet leaves it". This
principle is violated when connection doesn't
reach equilibrium, sender injects a new packet
before the old packet has exited or equilibrium
cant be reached because of resource limits along
the path.
The solutions presented deal with the scenarios
mentioned above with following mechanisms
Slow Start - To reach equilibrium (after
