problem1. describe briefly the differentiation between congestion control and flow control in relation to a connection-oriented protocol such as TCP.

problem2. What is the initial rate of data transfer in slow start phase of TCP congestion control, if the MSS is 1060 bytes and average RTT of 200 milliseconds?

problem3. Each and every host on the Internet is currently assigned an IP address 32 bits long (IPv4). IPv4 addresses are basically written as a series of four decimal numbers. IPv4 addresses traditionally belong to one of five classes of address, depending on type of network.

i. describe the structure of Class C address and a type of network it is suited for.

ii. Give two merits of creating subnets in a larger network.

iii. On an isolated network two hosts have been configured to work on the same subnet with IP addresses 10.10.201.254 and 10.15.201.254. Can this configuration work? What would the subnet mask require to be?

iv. Give five dissimilarities between IPv4 and IPv6?

Quetsion4. describe briefly the purpose of following protocols:

i. DHCP

ii. RARP

iii. ICMP
