c) Client A and Server B are communicating over a TCP connection. Client A started the three way handshake with the initial sequence number of 2905 . Server B's initial sequence number is 196. The window size of Client A is 591 bytes and the window size of Server B is 243 bytes. Client A sends the HTTP GET request of size 130 bytes within the third step of the TCP 3 way handshake (the ACK segment from the client). Server B answers with 2 segments containing the requested data. The first segment size is 68 bytes and the second segment size is 31 bytes respectively. Client A receives only the first segment within the timer. Unfortunately, the second segment did not reach Client A. So Client A sends an acknowledgement segment. Assume that Client A uses Go Back N protocol. I. What is the sequence number and acknowledgement number of the HTTP GET request segment from C lient A ? II. What will be the window size of the second ACK segment sent by Client A ?
