Router R1 is connected to another router R2 with link of L1 with a transmission rate of 67 packets/second. The link buffer at router R1 contains on an average 15 packets. There is one packet being currently transmitted. Average packet queuing delay is 15 milliseconds. Assuming no packet loss, what is the average packet arrival rate at R1?

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
