Chapter 4, Problem R34RQ
Program Plan Intro
Destination-based forwarding:
Destination based forwarding is a packet forwarding technique which is based on the destination address. Every data packet used in the transmission has the information of the address of the required destination.

Consider each layer of the TCP/IP protocol stack and order them from most important to least. Can one or more of these layers be combined or separated? Would the kind of information being sent affect how you order, and if so, why or why not? Why did you decide to place your order that way? To assist you, use the following scale: The most important component is represented by 1, while the least important factor is represented by 5.
1. Build a Router network which has three Generic
Routers and totally of Six networks in it. From each
Router the required switch shall be connected
through Fast Ethernet port and the switch is
connected to two users. On the whole there are '6'
networks in the configuration.
Along with the network diagram do the packet
transfer in simulation mode and write results
for three different combinations.
A frame containing http request is sent from Computer (A) [in whichever subnet it is now, make sure to show it in your figure], to the access point it is associated with. Draw the address fields (1, 2, and 3) of the frame travelling from Computer A to AP and the source and destination addresses of the frame travelling from AP to R1.
The MAC addresses of AP1, AP2, and AP3 are M1, M2, and M3 respectively, and the Router R1’s MAC address connected to this Switch/AP is MRA. IP address values are already given, and the port addresses could also be used as given. The Router’s MAC address facing WAN side is MRW.

- 4. The original HTTP protocol used TCP/IP as the underlying protocol. For each page, graphic, or applet, a separate TCP connection was constructed, used, and terminated. This caused several problems: one referred to as the elephant and mice problem and two aspects of connection overhead. Describe both problems. Why were separate connections used? Would UDP rather than TCP be a good alternative? What solution would you propose to these problems to improve HTTP performance?arrow_forwardA single connection has the capability to transmit multiple packets between hosts. This inquiry seeks to elucidate the concept of freight processing times. Is there a fixed duration for one delay while the other can be modified?arrow_forwardQ1.Suppose a client, say C, has established a TCP connection with a server, say S. After establishing the connection, the sender sends two TCP messages with data back-to-back ( the first TCP message with sequence number 32 and the second TCP message with sequence number 100). a. What is the sequence number chosen by the client? What could be the reason for choosing this value of sequence number?b. What is the data size of first and second TCP data messages?c. Suppose the server receives the first and second TCP messages with data with the difference of 100 milliseconds delay. What could be the ACK number for both the TCP data messages from the server side as per the TCP RFC.arrow_forward

She has been finding it difficult to track her sales and inventories, however recently after an expert's advice, she adopted a Point of Sale (PoS) server. So, she can now track her sales and inventories at the store. However, she ran into another issue, the server can only be accessed within the store, because it has been assigned a private IPv4 address, it is not publicly accessible via the Internet. a) Why is not having the PoS server accessible over the Internet a problem for the business? b) What caused this problem? c) Propose a solution for the problem and explain how the solution works.arrow_forwardProvide a succinct outline of the pros and cons of using connectionless protocols as an alternative to connection-based protocols as an alternative to connection-based protocols.arrow_forward
- Please give a short outline of the pros and cons of connectionless protocols as a possible solution for connection-based protocols.arrow_forwardA 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 transmitted in order of arrival. Suppose all packets are 1,500 bytes and the link rate is 2 Mbps. What is the queuing delay for the packet? More generally, what is the queuing delay when all packets have length L, the transmission rate is R, x bits of the currently-being-transmitted packet have been transmitted, and n packets are already in the queue?arrow_forwardProvide an example of a protocol at each of the TCP/IP model layers, for example that you have used in the above. Also give an example of overhead added in each of these protocols, e.g. a field in the protocol header. If possible, provide information on the maximum size of each packet, and the size of the header, of each of these example protocols.arrow_forward
- An HTTP client opens a TCP connection using an initial sequence number (ISN) of 14,534 and the ephemeral port number of 59,100. The server opens the connection with an ISN of 21,732. Show the three TCP segments during the connection establishment if the client defines the rwnd of 4000 and the server defines the rwnd of 5000. Ignore the calculation of the checksum field.arrow_forwardConsider the datagrams of each layer in the TCP/IP model, e.g., Frame at the Link Layer, Packet at the Internet Layer. Explain the functioning of the following protocols based on their datagram header fields only. Note: You do not need to describe the header field but based on the header field, explain how the protocol works, e.g., Acknowledgement field in a TCP Header is responsible for providing reliable data transfer and in case of data loss or ACK not received, segment is re-sent. You do not need to consider every field of the headers but wherever there are more than 4 fields, then based on 5 fields, describe its functioning, if less than or equal to 4 fields then consider all the fields.
