Problem:
(a) Explain how TCP handles connection-setup management.
(b) Each host on the Internet is currently assigned an IP address 32 bits long (IPv4). IPv4 addresses are usually written as a series of four decimal numbers. IPv4 addresses traditionally belong to one of five classes of address, depending on the type of network.
i. Give the address range for a Class D network. ii. What are Class D network addresses primarily used for? iii. Can two hosts A and B with IP addresses 172.16.17.25 and 172.16.27.25 respectively communicate directly with each other if they share a subnet mask of 255.255.248.0? iv. Describe one short-term technique which has been used to solve the shortage of IPv4 addresses?
(c) A datagram of 3000 bytes has to travel over a network with a MTU size of 1000 bytes. Describe how fragmentation can be used to solve this problem.
You should give the value of the key fields used in fragmentation for each fragment created.
