Networking Objective type Questions and Answers. The technique of temporarily delaying outgoing outgoing acknowledgements so that they can be hooked onto the next outgoing data frame is called piggybacking cyclic redundancy check fletcher’s checksum none of the mentioned. स्रोत : en. The technique of temporarily delaying outgoing outgoing acknowledgements so that they can be hooked onto the next outgoing data frame is called Computer Networks, 5th Edition, Pearson Education Limited,, 2014, p 226. References ^ Tanenbaum, Andrew & Wetherall, David. The sender also adds a counter (Emitter timeout), if the counter ends without receiving confirmation, the sender assumes packet loss, and sends the frame again. If the count ends and there is no data frame to send, the receiver will send an ACK control frame. This can be solved by enabling a counter (Receiver timeout) when a data frame is received. Disadvantages : The receiver can jam the service if it has nothing to send. Advantages and disadvantages Advantages : Improves the efficiency, better use of available channel bandwidth. Station B simply ignores this duplicate ACK frame upon receiving.

If station A wants to send just the data, then the previous acknowledgment field is sent along with the data. If station A wants to send the acknowledgment, after a short period of time to see whether a data frame needs to be sent, then decide whether send an ACK frame alone or attach a data frame with it. If station A wants to send both data and an acknowledgment, it keeps both fields there. Three rules govern the piggybacking data transfer. (ACK number is the next sequence number of the data to be PUSHed by the other party.) Whenever party A wants to send data to party B, it will carry additional ACK information in the PUSH as well.įor example, if A has received 5 bytes from B, which sequence number starts from 12340 (through 12344), A will place 'ACK 12345' as well in the current PUSH packet to inform B it has received the bytes up to sequence number 12344 and expects to see 12345 next time. In the data frame itself, we incorporate one additional field for acknowledgment (called ACK). Piggybacking data is a bit different from Sliding Protocol used in the OSI model. This technique of temporarily delaying the acknowledgment so that it can be hooked with next outgoing data frame is known as piggybacking. The delayed acknowledgment is then attached to this outgoing data frame. The receiver waits until its network layer passes in the next data packet. In two-way communication, whenever a frame is received, the receiver waits and does not send the control frame (acknowledgment or ACK) back to the sender immediately.
