Assume a router uses 4 buffers to store different traffic flows. It receives the packets listed in Table 1 at about the same time, in the order listed. All buffers are initially empty and transmission is not possible until all packets are received. Give the order in which packets are transmitted assuming that buffer 1 is a Priority Queue, and that buffers 2, 3 and 4 are scheduled using Weighted Fair Queuing, with flow 2 having weight 4, flow 3 having weight 2 and flow 4 having weight 1.

PLEASE ANSWER PROPERLY!
