A sender with window size (W=3) is connected to a selective repeat receiver by a link with bandwidth =10⁶ bytes/second and propagation delay of 0.25 msec. The receiver sends Positive ACK for correctly received packets. For each packet sent, the sender sets a timer with time out value of 5 msec. On receiving an ack for a packet, the timer for that packet is cancelled. If the timer expires, that packet is retransmitted immediately. Assume that the sender sends packets 1, 2, and 3 (at t=0, packet size =1000 Bytes) and packet 2 is lost. NO other packet is lost. Under this scheme , at what time would all the packets been received at the receiver. Please fill in your answer in msec. Do NOT write the units. just the value.
