Zeal online test series
When we use ipv6 and ipv4 together with the help of tunneling. So if the source set the hop count so will tunnel decrement the hop count. And if tunnel decrement it so wheater it decrement at both start and end of tunnel. Suppose source set hop limit to 16 and there are 2 router and tunnel on the path. So what will be the hop count after received by receiver.

Maximum Segment Size (MSS in TCP) vs Maximum Transmissible Unit (MTU in Data Link)
It is known that any network can only transmit data packet size equal to (or less than) MTU allowed in the network.

Computer Networks
Consider a network system consisting of three networks connected with two routers. Network-A has MTU of 1500 bytes, Network-B has MTU of 620 bytes, Network-C has MTU of 1500 bytes (MTU includes header size). Station-1 needs to send a segment of1380 bytes. The Total size of the packets received at Network-C is _________ bytes if the header size is 20 B.

Computer Networks: Basic doubt in TCP operation
When we have a segment of say 100 bytes and my last ACK number is assume 4000, Now my current sequence number will be (4000-4099) for 100 bytes segment. This is what we generally use a notation. But in one segment we have only one field as sequence number.So how can we specify Range? Ip has length fields in Ipv4/V6/UDP but why not in TCP?

Computer network MSS and MTU
Are these definations of MSS and MTU correct?? MSS is maximum payload of TCP segment. TCP segment (MSS + TCP header) For IPpacket, it consists of (MSS + TCP header + IP header) And payload of IP packet means (TCPheader + MSS) Ethernet frame ... Also is fragmentation always done at router?? Can it be done by source?? I am really confused about these terms. Plz verify.
