Question

Q2. suppose a tcp message that contains 2,048 bytes of data and 20 bytes of tcp header is passed to ip for delivery across two networks of the internet (i.e., from the source host to a router to the destination host). the first network uses 14-byte headers and has an mtu of 1,024 bytes; the second uses 8-byte headers with an mtu of 512 bytes. each network's mtu gives the size of the largest ip datagram that can be carried in a link layer frame. give the sizes and offsets of the sequence of fragments delivered to the network layer at the destination host. assume all ip headers are 20 bytes.

Answer 1

vSuppose the population of the world is 6 billion, and that there is an average of 1000 communicating devices per person. how many bits are required to assign a unique host address to each communicating device? suppose that each device attaches to a single network and that each network on average has 10000 devices. how many bits are required to provide unique network ids to each network?
