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.

Consider an employee using their computer to send and retrieve email at their workplace. Only Ethernet networks are used for physical connectivity, but the mail server is located on a separate network. The employee’s network and the mail server’s network are connected by a single router which also has a connection to the Internet via the workplace’s ISP. Explain how the employees email client sends and receives emails using the email server, indicating any protocols involved and where any encapsulation/decapsulation occurs as data travels between the client, local mail server, and remote mail servers.

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 to be sent from source to destination in Figure 1.27. Suppose each link in the figure is 2 Mbps. Ignore propagation, queuing, and processing delays. a. Consider sending the message from source to destination without message segmentation. How long does it take to move the message from the source host to the first packet switch? Keeping in mind that each switch uses store-and-forward packet switching, what is the total time to move the message from source host to destination host? b. Now suppose that…

3. Consider the M/M/1 queue discussed in class. Assume that packets arrive to a queue with average arrival rate A [pkts/s]. The average service rate of the queue is denoted by u [pkts/s]. (a) Write expressions for: (i) the mean time between packet arrivals to the queue, i.e., the average inter-arrival time; and (ii) the mean service time, i.e., the average time needed to transmit a packet onto the outgoing link. (b) Let N denote the number of packets in the system in steady-state. Suppose A = 850 and u 1000. Find the smallest value of B such that P(N > B) < e = 10¬4. Hint: Use MATLAB or some other computational tool (you could even use an Excel spreadsheet) to test different values of B. 4. Consider the M/M/1 queue from Problem 3.

Suppose two TCP connections share a path through a router R. The router's queue size is six segments; each connection has a stable congestion window of three segments. No congestion control is used by these connections. A third TCP connection now is attempted, also through R. The third connection does not use congestion control either. Describe a scenario in which, for at least a while, the third connection gets none of the available bandwidth, and the first two connections proceed with 50% each. Does it matter if the third connection uses slow start? How does full congestion avoidance on the part of the first two connections help solve this?

Assume the maximum transmission unit (or MTU) of an IP packet on 100 Mbps Ethernet is set at 1500 bytes. Also, assume we are sending our file using IPv6 at the Network layer and UDP at the Transport layer. A typical IPv6 header consists of 40 bytes, a UDP header consists of 8 bytes. Answer the following three questions based on the information provided above. For all answers, enter a decimal integer value without formatting (no commas). 1. How many packets do we have to send in order to transfer a file of 24KB over 100 Mbps Ethernet? packets 2. How many bytes do we have to send at the network layer in order to transfer the above file entirely? bytes 3. How many bytes do we have to send at the data link layer in order to transfer the above file entirely? Assume that the Ethernet header is 14 bytes and the frame checksum is 4 bytes. bytes
