Assume that a source sends a message containing 8 packets to the destination and
there are 4 routers on the path. Assume the bandwidth of each link is 200 Mbps, and the size of
each packet is 16 Kb. Assume the length of each link is 20 kilometers, and the propagation speed is
2 x 108 meters per second. Assume each router begins retransmitting a packet after it has finished
receiving the packet and processed it for 4 microseconds (dproc = 4 µs). There is no queueing delay.
Calculate the end-to-end delay to this message (from first bit sent to the last bit received).

1.       In modern packet- switched networks, including the Internet, the source host segments long, application- layer messages (for example, an image or a music file) into smaller packets and sends the packets into the network. The receiver then reassembles the packets back into the original message. We refer to this process as message segmentation. Figure 1.27 illustrates the end- to- end transport of a message with and without message segmentation. Consider a message that is 8 · 106 bits long that is...

1. Host A and Host B are connected by a network with 2 store-and-forward switches. Each link has a bandwidth of 5 megabits/second and is 1,000 kilometers long. The network propagation speed is 200,000 kilometers/second. Host A sends 10,000-bit packets to Host B. Give proper units on each answer. (For these and other numerical problems it is required that you give a formula, using numbers from the problem, that can be evaluated to give the numerical answer.) a) What is...

An 8850-byte message is split into 10 packets where each packet is encapsulated with a 20-byte header and no trailer. If it takes 70 hops to reach the destination, what is the message transmission time? Assume it takes 1 ns to transmit 1 byte of data. Also assume all switches and routers in the network are store-and-forward. • Show your work.

1.       Suppose there are two routers between a source host and a destination host. Ignore fragmentation; an IP datagram sent from the source host to the destination host will travel over how many interfaces? How many forwarding tables are there to move the datagram from the source to the destination? 1.       Consider a datagram network using 32-bit host addresses. Suppose a router has three links, numbered 0 through 2, and packets are to be forwarded to the link interfaces as follows: Prefix                                   ...

Consider sending a file of 1 Mbits over a path of 5 links. Each link transmits at 10 Mbps. The network is lightly loaded so that there are no queuing delays. Propagation delay is negligible. When a form of packet switching is used, the file is broken up into 10 packets; each packet with 100 Kbits. Suppose the network is packet-switched virtual-circuit network. Denote the VC setup time by 10 milliseconds. Suppose the sending layer add a total of 100...
