Question

If 4-bit sequence number is used in protocol 5, what would be the size of buffer? Why? Drawthe initial sender and receiver sliding windows. Draw the sender and receiver sliding windowsfor the situation where the sender has sent the first few frames and has stopped sendingbecause it has to now wait for an acknowledgements. Also the receiver has received all theframes that sender has sent so far and has sent all the acknowledgements. But the acknowledgements are lost

Answer 1

The above Question we can use the is bit sequence number the Butter site for the sliding window is one more than the sequence number. It means the values can start with zero onwards So the Buffer site is five bits. And the above date transformed in siding window is Sliding window an used where reliable in order of packets is required the ordering of the is defined using sequence numbers which are on every In two way communications both sides agree to a window size before transmitting any containing Actual data that window site could be fixed or dynamically changed So for client communication say the window site is 6 Relying on the sequence numbers this means it is initially from with sequence to with sequence \r\n After Agreement take place and data Trans mission begins the client will start sending the first with sequence no's 1, 2, 3, 4, 5, 6 Client A will stop
