Q.1. Consider the network that is shown below. For all packets in this network, the packet sizes are exponentially distributed with an average size of 1000 bits/packet. All packet generation processes are Poisson processes. Ignore all propagation delays. Router 1 has 2 inputs, 2 outputs. Router 2 has 2 inputs and 1 output. Network 3D Link rate Link rate: 100kbps- 10 Kpackets/sec Router 2 A-spackets sec-Ragn ene HostA #1 0Kpackets/sec / 5Kpackets/sec Host B Network1 Network 2 _THI Host A generates packets with a rate of 2-5 packets/sec and sends them to Host B over Router 1 and Router 2. Traffic from Network I has a rate of ?,-10Kpackets/sec. 10% of these arrivals are routed to Network 3 and the rest ofthem go on thecomponenteoftheftalaverage delay tentfromHost AtoHostCaaaa0Pat to Router 2, Traffic from Network 2 has a rate of ?:"5Kpackets/sec. a) What are the components of the total average delay for a packet that is sent from Host A to Host B. b) What is the total average delay for a packet that is sent from Host A to Host B. Clearly specify all your assumptions and the properties that you use.
