Consider the Selective Repeat protocol with a send window size of 8, a receive window of size 8, and 10 bit sequence number Suppose that at time t 1 , the sender has sent Packets 0 through 9 and has received ACK0, ACK1, ACK2, ACK4, and ACK5 The receiver has received Packets 0 through 6, and Packet 8 Answer the following questions What sequence numbers are contained in the send window What sequence numbers are contained in the receive window Suppose at time t 1 , timeout occurs for Packet 3, what will the sender do Suppose at time t 2 t 1 , the sender receives ACK3 Will the sender update the send window If so, how Suppose soon after t 1 , the receiver receives Packet 7 Will the receiver deliver any packet(s) to the upper layer If so, which packet(s) will be delivered Will the receiver send an ACK If so, what is the sequence number being ACKed

Question: Consider the Selective Repeat protocol with a send window size of 8, a receive window of size 8, and 10-bit sequence number. Suppose that at

Consider the Selective Repeat protocol with a send window size of 8, a receive window of size 8, and 10-bit sequence number. Suppose that at time t₁, the sender has sent Packets 0 through 9 and has received ACK0, ACK1, ACK2, ACK4, and ACK5. The receiver has received Packets 0 through 6, and Packet 8. Answer the following questions:

What sequence numbers are contained in the send window?
What sequence numbers are contained in the receive window?
Suppose at time t₁, timeout occurs for Packet 3, what will the sender do?
Suppose at time t₂ > t₁, the sender receives ACK3. Will the sender update the send window? If so, how?
Suppose soon after t₁, the receiver receives Packet 7. Will the receiver deliver any packet(s) to the upper layer? If so, which packet(s) will be delivered? Will the receiver send an ACK? If so, what is the sequence number being ACKed?
