Tanenbaum-Q35 (Network layer)
A router is blasting out IP packets whose total length (data plus header) is 1024 bytes. Assuming that packets live for 10 sec, what is the maximum line speed the router can operate at without danger of cycling through the IP datagram ID number space?

Tanenbaum- Q34 (Network Layer)
Suppose that host A is connected to a router R 1, R 1 is connected to another router, R2, and R2 is connected to host B. Suppose that a TCP message that contains 900 bytes of data and 20 bytes of TCP header is passed to the IP code at ... including an 8-byte frame header, and link R2-B can support a maximum frame size of 512 bytes including a 12-byte frame header.

Tanenbaum-Q-21 (Network Layer)
As a possible congestion control mechanism in a subnet using virtual circuits internally, a router could refrain from acknowledging a received packet until (1) it knows its last transmission along the virtual circuit was received successfully and ... the destination host? Assume that transmission errors are rare and that the host-router connection is infinitely fast.

Selective Repeat
Consider the operation of SR protocol over a 1-Mbps error-free line. The maximum frame size is 1000 bits. New packets are generated 1 second apart. The timeout interval is 10 msec. If the special acknowledgement timer were eliminated, unnecessary timeouts would occur. How many times would the average message be transmitted?

Back off algorithm
How the collison probability for A and B for the first round is 1?? A and B can take values between (0,1) .. this gives 4 combinations (0,0),(0,1),(1,0) and (1,1) ? Prob(collison)= 2/4 =0.5 . . Isn't it??? plz check this https://gateoverflow.in/66836/madeeasy-2017
