In previous article we have discussed about sliding window protocol. One bit sliding window protocol is based on the concept of sliding window protocol. But here the window size is of 1 bit.
- One bit sliding window protocol is used for delivery of data frames.
- Sender has sending window.
- Receiver has receiving window.
- Sending and receiving windows act as buffer storage.
- Here size of windows size is 1.
- One bit sliding window protocol uses Stop and Wait.
- Sender transmit a frame with sequence number.
- Than sender wait for acknowledgment from the receiver.
- Receiver send back an acknowledgement with sequence number.
- If sequence number of acknowledgement matches with sequence number of frame.
- Sender transmit the next frame.
- Else sender re-transmit the previous frame.
- Its bidirectional protocol.
