Assume a constant round-trip delay between the sender and receiver, and that the sender is aware of this delay before starting. Due to the probability of packet loss, is a timer still necessary in protocol rdt 3.0? Explain.

Assume that there is a constant roundtrip delay between the sender and the recipient, and that the sender is aware of this delay. Is the use of a timer in protocol rdt 3.0 still required, given the possibility of packet loss? Explain.

Assume a constant round-trip delay between the sender and receiver, and that the sender is aware of this delay before starting. Due to the probability of packet loss, is a timer still necessary in protocol rdt 3.0? Explain.

Assume that the sender and receiver both have a constant roundtrip delay, which the sender is aware of. Is a timer still required in protocol rdt 3.0, given the possibility of packet loss? Explain.

Draw a space-time diagram similar to Figure 3.22 of textbook for the following problem: Sender is sending 10 packets to receiver. Stop after 7 packets are accepted by receiver. Protocol Used: Go-Back-N Sliding Window size = 6 Timeout interval =1RTT Assume transmission time of a packet = 1/4 RTT Assume Packet 1 is lost, then ACK 2 is lost, and then ACK 6 is lost Note: The sender starts a timer when base = nextseqnum, i.e. at beginning of your example. Then when an ACK is received, if base is not nextseqnum, the timer is started.

Do Selective Repeat Protocols only retransmit packets that were lost or corrupted at the receiver?

Assume that there is a consistent roundtrip delay between the sender and the receiver, and that the sender is aware of the delay. Is the inclusion of a timer in protocol RDT 3.0 still required, considering the possibility of packet loss? Explain.
