1.3-1 Routing versus forwarding.  Choose one the following two definitions that makes the correct distinction between routing versus forwarding.

1.4-1 Components of packet delay. Match the description of each component of packet delay to its name in the pull down list.

a. What are the five protocol layers, from top to bottom, in the Internet?

In a virtual-circuit packet-switched network, a packet switch maintains state information for each connection passing through the router.

Suppose there are two links between a source and a destination. The first link has transmission rate 100 Mbps and the second link has transmission rate 10 Mbps. Assuming that the only traffic in the network comes from the source, what is the throughput for a large file transfer?

The Internet provides its applications two types of services, a TDM service and a FDM service.

We are sending a 30 Mbit MP3 file from a source host to a destination host. All links in the path between source and destination have a transmission rate of 10 Mbps. Assume that the propagation speed is 2 * 10⁸ meters/sec, and the distance between source and destination is 10,000 km.

We are sending a 30 Mbit MP3 file from a source host to a destination host. All links in the path between source and destination have a transmission rate of 10 Mbps. Assume that the propagation speed is 2 * 10⁸ meters/sec, and the distance between source and destination is 10,000 km.

Initially suppose there is only one link between source and destination. Also suppose that the entire MP3 file is sent as one packet. , the end-to-end delay (transmission delay plus propagation delay) is?
