Forouzan's Sliding Window Numerical
I was scrolling through sample questions when I chanced over this question. Consider a sliding window flow control protocol between hosts A and B. Suppose the link propagation delay is 1 time unit, the retransmission timeout is 3 time units ... I would really appreciate any help regarding this question. Also, can someone please leave a link to similar questions?

Go Back N flow control
I had a doubt regarding one scenario in Go Back N flow control algorithm. Consider the following scenario shown in the image The left hand side is the sender and the right hand side is the reciever. I referred to Kurose Ross Extended FSM Description of GBN sender ... window(packets 1, 2 and 3). Is this correct? Can such a scenario even occur in real life? Thanks in advance.

Finding optimal window size
Finding Optimal Window Size In Slinding Window Protocol. Given Round trip time(RTT sec), Bandwidth(BW bits/sec), packet size(L bits), which approch is right? Approch 1. max data that can be sent in RTT = RTT * BW bits max window size = (RTT * BW)/L ... = (1 + 2a) packets; a=Tp/Tt Some problems are sloved with approch 1 and others with 2nd one. Which one should we use?

Made easy question about sliding window protocol
Options are: 8,4,6,7. This is a multiple correct question. Answer as per key is 8,6,7 Their explanation is this: My doubt: if the window size is 8, then why does the sender wait for acknowledgement after sending 3 packets? It can send more without waiting.

Supernetting Rules (Self Doubt)
I have read rules of supernetting from a few sources and have got conflicting information. this (3:20) , this and this say that the rules are: 1.All the Networks should be contiguous. 2.The block size of every networks should be equal ... 2 and first address being divisible by "number of blocks" in the supernet. What is going wrong? Am I missing something?
