Consider a router connecting an input link to an output link. This router has a buffer where it can store packets that are waiting to be transmitted on the output link. After monitoring this router for some time, it was found that: packets arrive to the router on average at a rate of 200 packets/sec there is on average 25 packets in the router including the packet being transmitted. the average time a packet spends in the buffer is 85 msec a) What is the average total delay experienced by a packet in this system, assuming there is no packet loss? b) What is the output link transmission rate in packets/sec?

Consider a router connecting an input link to an output link. This router has a buffer where it can store
packets that are waiting to be transmitted on the output link.
After monitoring this router for some time, it was found that:
packets arrive to the router on average at a rate of 200 packets/sec
there is on average 25 packets in the router including the packet being transmitted.
the average time a packet spends in the buffer is 85 msec
a) What is the average total delay experienced by a packet in this system, assuming there
is no packet loss?
b) What is the output link transmission rate in packets/sec?
