TCP MULTIPLEXING AND DEMULTIPLEXING In the scenario below, the left and right TCP clients communicate with a TCP server using TCP sockets. The Python code used to create a single welcoming socket in the server is shown in the figure (the welcoming socket itself is not shown graphically); code is also shown for the client sockets as well. The three sockets shown in server were created as a result of the server accepting connection requests on this welcoming socket from the two clients (one connection from the client on the left, and two connections from the client on the right). mySocket = socket (AF_INET, SOCK_STREAM) mySocket.bind (myaddr, 6189 ); P1 Answer mySocket = socket (AF_INET, SOCK_STREAM) mySocket.bind (myaddr, 5854 ); ♫ transport QUESTION 1 OF 8 network link physical What is the source port # for packet C? www B source port: ? dest port: ?

For NAT Network Address Translation Scenario: Jenny Bello is a small business owner selling and making customized computer peripherals. 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.

Where the first char ‘1’ represents the cm to inches and the other 2 chars represents the 10.
We have seen that Internet TCP sockets treat the data being sent as a byte stream but UDP sockets recognize message boundaries. What are oneadvantage and one disadvantage of byte-oriented API versus having the API explicitly recognize and preserve application-defined message boundaries?

Talk about the features of Network APIs and how they may be used in practise by giving the example of a phone conversation. In other words, (socket-related) functions.
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.
There are many techniques, approaches or architectures that extend the concept of a local method or function call to remote connections. In the lecture we have seen RPC2, XML- RPC, Java Sockets, JAVA RMI, CORBA, Message Oriented Middleware, SOAP (Simple Object Access Protocol), RESTful Services and gRPC. Assume you are a Software Developer who has been asked to use a lightweight approach to link legacy Java Software with a newly developed GUI, also written in Java. Recommend one of the techniques from the above list and justify your decision.
4. [Socket] What is a socket? Suppose a process in Host C has a UDP socket with port number6789. Suppose both Host A and Host B send a UDP segment to Host C with destination portnumber 6789. Will both segments be directed to the same socket at Host C? If so, how will theprocess at Host C know that these two segments originated from two different hosts? 5. [Demultiplex] Define multiplexing and demultiplexing. Briefly explain how TCP demultiplexing isdifferent than UDP demultiplexing. 6. [rdt] Consider a reliable data transfer protocol that uses only negative acknowledgments.Suppose the sender sends data only infrequently. Would a NAK-only protocol be preferable to aprotocol that uses ACKs? Why? Now suppose the sender has a lot of data to send and the end-to-end connection experiences few losses. In this second case, would a NAK-only protocol bepreferable to a protocol that uses ACKs? Why?
(a) Suppose a server S and client C are connected over the Internet. The one-way prop- agation delay from S to C is 50 ms. The maximum throughput between S and C is R = 200 Mbps. A browser on client C makes an HTTP request for a webpage on server S. The base HTML file is of size 500 KB and it references five objects, each of size 5 MB. Find the total response time for the client to receive the entire webpage using nonpersistent HTTP with up to two parallel connections. Assume that when two par- allel connections are active, the throughput for each connection is 40% of the maximum throughput R. (b) Suppose an application running on host ece.gmu.edu needs to resolve the domain name cs.vtech.edu. Draw a diagram (with labels) showing the sequence of queries/responses in a recursive DNS query to find the answer in a scenario where all levels of the DNS hierarchy are involved.
