Subject: Computer network

Question:

Suppose in the abovefigure Data[1] and Data[2] had been lost, but not Data[4].

(a). The third dupACK[0] is sent in response to whatData[N]?

(b). When the retransmitted Data[1] reaches the receiver, ACK[1]is the response. When this ACK[1] reaches the sender, which Datapackets are sent in response?

please provide a write answer
