TCP connection has been established and client has declared its window size as 20000 bytes. Congestion window is also set at the same size. Server already sent two segments to client. A server sends third segment with sequence number 1460 to a client. It then sends fourth segment with sequence number 19921. Just after this, server gets the third duplicate ACK from the client with the ACK no.17001. At this point, what will be the threshold value (in bytes) and also determine the size of the third segment. Answer Threshold value (in bytes) The size of the third segment.
