Line 160:
- Starts the Congestion Avoidance phase
- This is called fast transmission and fast recovery
*Silly Window Syndrome: Sender creates data slowly or Receiver consumes slowly or both.
Syndrome due to Sender:
- '''Nagle’s Algorithm''': Send data initially, accumulate data in output buffer, Wait for Ack or till 1 MSS Data in Buffer
Syndrome due to Receiver:
- '''Clark’s Solution''': Announce window size 0 till 1) enough space for 1 MSS in Buffer or Half Receive buffer is empty
- '''Delayed Acknowledgment''': Segment not acknowledged immediately, Sender TCP does not slide its window, reduces traffic, sender may unnecessarily retransmit, Not delay more than 500 ms.
