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.
