Q$2.$ Let nodes A and B be connected by a network path with $100$ms round$-$trip time. Assume each TCP packet can carry $1500$ bytes of TCP data in its payload. Ignore the packet header overhead and transmission delay. Also, you may assume that the receiver advertised window size is sufficiently large so as to not impact the sender$.$

Q$2.$a$)$Node A wants to transmit $78,000$ bytes of data to node B$.$ Let T$1$ be the time at which node A starts to send its first data packet. $($Note that this is after the TCP connection is established.$)$ Assuming no packet loss, an initial congestion window of one packet, and the initial threshold is $64,$ what is the time at which node A receives the acknowledgment for the last packet from its transfer?
