Consider a packet-by-packet fair queuing system with three logical buffers and with service rate of one unit/second. Show the sequence of transmissions for this system for the following packet arrival pattern. Buffer 1: arrival at time t = 0, length 2; arrival at t = 4, length 1. Buffer 2: arrival at time t = 2, length 4; arrival at t = 3, length 1. Buffer 3: arrival at time t = 3, length 5. You need to find out the finish tag, order of transmission and actual packet completion times for each packet arrival. (Explain with diagram)
