In a fast Ethernet cabling, 100 Base-TX uses twisted pair cable and maximum segment size is 100 metres.

An IP datagram of size 1000 bytes arrives at a router. The router has to forward this packet on a link whose MTU (maximum transmission unit) is 100 bytes. Assume that the size of the IP header is 20 bytes. The number of fragments that the IP datagram will be divided into for transmission is:

Consider a simplified time-slotted MAC protocol, where each host always has data to send and transmits with probability p = 0.2 in every slot. There is no backoff, and one frame can be transmitted in one slot. If more than one host transmits in the same slot, the transmissions are unsuccessful due to collision. What is the maximum number of hosts this protocol can support if each host has to be provided a minimum throughput of 0.16 frames per time slot?
