OSI Model
Network layer is used when data is to be delivered across network. So, for delivering within a network, there is no need for network layer (Ref: Pg-49, Computer Networks, Forouzan, 2 Edition). So in that case will Transport layer directly communicate with Data Link layer ? Or will Network layer be in picture, but do nothing other than simply passing data to Transport layer ?

Fragmentation
Which of the following statements is/ are true about the fragmentation which is done at network layer. (I) The offset of 1st fragment is always offset of parent. (II) The MF of last fragment is always same MF of parent. I think I is true and II is false: Explanation for II :- Host A ... MF = 1 packet 1.3 <20,40> MF = 0 packet 1.3's MF != MF of packet 1 In A-R1. is it correct.

Fragmentation
Suppose a network:- Suppose a TCP message contains 492 B of data and TCP header is of size 20B then deliver it to IP. IP header is 20 B. Assume link A-R1 has the maximum frame size of 700 B including a frame size of 14 B, link R1-R2 can support a ... of 256 B including a 12 B frame header. Then calculate the no of fragments at each link and show the format of fragments in each link.

Fragmentation Ipv4-Ipv6
True or false - 1. In Ipv4 fragmentation can be done both at Source and intermediate routers. 2. In Ipv6 fragmentation can be done only at Source and not intermediate routers. 3. In both IPv6/4 reassembly is done only at the destination. 4. ... fragmentation done at the Source in Ipv4? Should the 1) be false since segmentation is done and hence fragmentation can be avoided?
