  1. Suppose N packets arrive simultaneously to a link at which no packets are currently being transmitted or queued. Each packet is of length L and the link has transmission rate R. What is the average queuing delay for the N packets?
  2. Now suppose that N such packets arrive to the link every LN/R seconds. What is the average queuing delay of a packet?

A packet switch receives a packet and determines the outbound link to which the packet should be forwarded. When the packet arrives, one other packet is halfway done being transmitted on this outbound link and four other packets are waiting to be transmitted. Packets are ... rate is R, x bits of the currently-being-transmitted packet have been transmitted, and n packets are already in the queue?

(Common data question P10, P11) P10. Consider a packet of length L which begins at end system A and travels over three links to a destination end system. These three links are connected by two packet switches. Let $d _i, s _i, and R _i$ denote the ... forward packets but instead immediately transmits each bit it receives before waiting for the entire packet to arrive. What is the end-to-end delay?

Suppose two hosts, A and B, are separated by 20,000 kilometers and are connected by a direct link of R = 1Gbps. Suppose the propagation speed over the link is $ 2.5 10^8$ meters/sec Calculate the bandwidth-delay product, $R \times d _{prop}$. Consider sending a file of ... the maximum number of bits that will be in the link at any given time? What is the width (in meters) of a bit in the link?

Suppose two hosts, A and B, are separated by 20,000 kilometers and are connected by a direct link of R = 2 Mbps. Suppose the propagation speed over the link is 2.5×1082.5×108 meters/sec. suppose we can modify R. For what value of R is the width of a bit as long as the length of the link?
