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 in msec would all the packets been received at the receiver.

Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.
