A new design of router and switch is proposed in this paper to decrease the unnecessary wastage of transmission bandwidth capacity because of retransmission of corrupt or lost packets. A buffer memory is joined to every router and switch. Every one of the packets that go through a router is stored in the buffer memory for a short time. On the off-chance that a packet is discarded at any router, it tends to be asked from the past router, which has a duplicate of the packet in its buffer. Through our approach, we spare a great deal of data transmission bandwidth, as a retransmission from sender to receiver isn’t required. If there arises an occurrence of any discarded or corrupt packet, then an additional bandwidth capacity required for retransmission is not required. This paper gives a brief explanation on how to reduce retransmission time and increase its throughput.
