(b) A TCP segment with 3400 bytes is passed to IP for delivery across two networks of the Internet. The first network (link) uses 30-bytes headers and has a frame size of 1000 bytes; the second network uses 20 -bytes headers with a frame size of 700 bytes. Give the details (total length, offset and the more flag) of the sequence of fragments delivered to the network layer at the output of the two networks. Assume all TCP and IP headers are 20 bytes.
