In the description of TCP congestion control, the value of the threshold, ssthresh, is set as ssthresh=cwnd/2 in several places and ssthresh value is referred to as being set to half the window size when a loss event occurred. Must the rate at which the sender is sending when the loss event occurred be approximately equal to cwnd segments per RTT?

Answer / Explanation:

To answer this question, we need to understand the meaning of some abbreviated term and what they mean. This includes:

TCP: Transmission Control Protocol

Congestion: This can be described as the restriction or blocking of a pathway of something.

Now if we relate it to the question asked, TCP control protocol congestion control is simple a type of algorithm procedure to avoid network congestion.

Now, If the pace at which a sender is sending is approximately equal to congestion window segments per RTT then the loss event is occurring.

Sound is a variable operated at the sender side so it can be used to execute a constraint on the traffic rate.

We should also know that ssthresh which can also be represented as slow start threshold is used to store second state value. When a segment loss event is occurring and the TCP, sender identifies the loss then the value of ssthresh is reset.

So, sender rate is cwnd/RTT.
