3.12 - Flow Control and Congestion Control
"This video describes about Flow Control and Congestion Control with different cases.
Also describes various approaches towards Congestion Control."
"Flow control:
It is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver.
It prevent receiver from becoming overloaded.
Receiver advertises a window rwnd(receiver window) with each acknowledgement.
Congestion Control:
Too many sources sending too much data too fast for network to handle.
When a connection is established, a suitable window size has to be chosen. The receiver can specify a window based on its buffer size.
If the sender sticks to this window size, problems will not occur due to buffer overflow at the receiving end, but they may still occur due to internal congestion within the network.
Two broad approaches towards congestion control:
1. End to End congestion control
2. Network-assisted congestion control
