Computer NetworksIn a sliding window ARQ scheme, the transmitter's window size is N and the receiver's window size is M. The minimum number of distinct sequence numbers required to ensure correct operation of the ARQ scheme is (i) min(M, N) (ii) max(M, N) (iii) M + N (iv) M × N20162mComputer NetworksConsider a sender S and a receiver R that are connected on a network, where the one-way latency is 250 milliseconds. The data rate of that network is 32000 bits per second, and size of each frame in that network is 1000 bits. Assume that S and R are using sliding windows with Selective Repeat. How large must the sliding window for S be in order to maximize the utilization?20237mComputer NetworksWhat is the maximum size of data that the application layer can pass onto the TCP layer below? (i) Any size (ii) 2^16 bytes-size of TCP header (iii) 2^16 bytes (iv) 1500 bytes20212mComputer NetworksA TCP connection is using a window size of 10,000 bytes, and the previous acknowledgment number was 22,001. It receives a segment with acknowledgment number 24,001 and window size advertisement of 12,000. Draw a diagram to show the situation of the window before and after.20207m

All packets are ready and immediately available for transmission. If every 5th packet that A transmits gets lost (but no packets from B ever get lost), then what is the number of packets that A will transmit for sending the message to B?
