Each router has fixed number of buffers which excludes the buffer for receiving and transmittinga packet. A router can receive and transmit concurrently. Each router uses Store and Forwardmechanism. If a router receives more packets than its buffer size, then it will drop the incomingpacket. The number of buffers for each router are to be taken based on last $3$ digits of your UMBCId. If the digit value is $0,$ then its value should be taken as $10.$ For example, your UMBC id isXY$97503,$ then queue buffers for R$1,$ R$2$ and R$3$ respectively would a$=5,$ b$=10$ and c$=3$
