n TCP connections sharing a bottleneck
TCP:
· Distributed Congestion Control algorithm
· The TCP sender detects congestion on the network through
the feedback received from the TCP receiver
The packet sending rate (congestion window) is adapted dynamically
· Increase in absence of packet losses
· Decrease upon reception of congestion notification
Current TCP Implementations:
· AIMD paradigm : The increase is linear in time
· Problem in fully utilizing the link capacity in the presence of High-Speed
links
The MIMD TCP is one of the possible alternatives
