For the above scenario, the receiver sent an acknowledgement packet with ackNo = 1165 and rwnd=862. What is the sliding window size of the sender? Did the window open or close and from which direction/s (e.g left and/or right direction/s)? Briefly explain. A client residing on a host with IP address 192.70.21.68 sends a message to 5 points the corresponding server residing on a host with IP address 192.25.48.89. If the well-known port is 160 and the ephemeral port is 50169, what's the socket address of the destination of the packet when the client is replying? Labiba and Sharmin are communicating over a TCP connection. Sharmin's receiving window size is 2121. Labiba used Go Back N protocol to send segment-1(sequence number=1221) of size 221 bytes and segment-2 of size 122 bytes. But segment-1 is lost on the way and only segment-2 reaches Sharmin. Sharmin sends an acknowledgement packet to Labiba. What will be the window size in this packet. Did Sharmin store segment-2 in her buffer? In the above scenario, Labiba re-sends both the segments again and this time both segments reached Sharmin. However, Sharmin could only process segment-1 and send it to the application layer. Sharmin sent an acknowledgement packet to Labiba. What is the window size of this packet? What is the sequence number of segment-3 that Labiba will send? In the above scenario, Labiba re-sends both the segments again and this time both segments reached Sharmin. However, Sharmin could only process segment-1 and send it to the application layer. Sharmin sent an acknowledgement packet to Labiba. What is the window size of this packet? What is the sequence number of segment-3 that Labiba will send?
