tcp/ip sliding window

[agbey]

what is the explaination for sliding window in networking. can someone help.

Hi,

Please re-phase your question.
I don't understand what you need.

hello
sliding window is a data transmition protocol used in transport layer that ensures the delivery of packets.
here is a link for more info on this topic: https://en.wikipedia.org/wiki/Sliding_Window_Protocol

I suggest you conduct further reading about OSI layers in order to make it clearer to u to understand.
best regards

thanks, i've got it

A sliding window protocol is a feature of packet-based data transmission protocols. Sliding window protocols are used where reliable in-order delivery of packets is required, such as in the Data Link Layer (OSI model) as well as in the Transmission Control Protocol (TCP).

Conceptually, each portion of the transmission (packets in most data link layers, but bytes in TCP) is assigned a unique consecutive sequence number, and the receiver uses the numbers to place received packets in the correct order, discarding duplicate packets and identifying missing ones. The problem with this is that there is no limit of the size of the sequence numbers that can be required.

By placing limits on the number of packets that can be transmitted or received at any given time, a sliding window protocol allows an unlimited number of packets to be communicated using fixed-size sequence numbers.

For the highest possible throughput, it is important that the transmitter is not forced to stop sending by the sliding window protocol earlier than one round-trip delay time (RTT). The limit on the amount of data that it can send before stopping to wait for an acknowledgment should be larger than the bandwidth-delay product of the communications link. If it is not, the protocol will limit the effective bandwidth of the link.
