Question

Let MSS, RTT, cwnd, rwnd be the maximum segment size, round-trip time, congestion window size, receiver window size, respectively. Answer the following: (a) The average initial transmission rate of a TCP connection is (b) The average transmission rate of a TCP connection is (c) The new values of TCP congestion window size and the threshold are_ and when a triple duplicate ACK is received (d) The new values of TCP congestion window size and the threshold are (e) During congestion avoidance phase, the new value of TCP congestion window size is set to (f) The sender can send up to and when a timeout occurs. every TCP segments in a period of one

Explanation / Answer

Solution:

a)

The initial transmission value in TCP Reno is 1 or 2.

b)

The average transmission rate= (SSThresh*(SSThresh-1)/(2*number of ACKs received.)

c)

SSThreshold= cwnd/2, and cwnd= SSThresh+3

d)

cwnd= 1 or 2, and

·, In this case, the value of ssthresh will be changed and it will become Flight size/2.

·         Flight size=> The size of the data which was sent the last time when timeout happened.

f)

cwnd= cwnd + 1/cwnd

g)

SSTHRESH, timeout.
