In SWP if first packet is transmitted on link, will it wait for window size to fill completely or start propagating?

Question

In SWP, if windows size of the sender is 5, transmission delay is 15ms and propagation delay is 25ms.

So,if first packet is transmitted on link, will it wait for the windows size to fill completely or it will start propagating?

I think it will start propagating, because its independent of propagation delay?!

Comments

In this case, is it correct that first ack is received before all the packets in the sender's window are transmitted?

and what will be the throughput in this case?

Answer 1

Yes, it will start propagating as soon as it is available. SWP means we cannot send more packets than the size of window.

Answer 2

No it will not wait , it will send if  further frames are not generating on Tranmitter side ,

but the maximum size it can sed = window Size

First thing new packets wont be filled in the window until whole window is ack First
