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 mySocket = socket (AF_INET, SOCK_STREAM) mySocket.bind (myaddr, 5854 ); + transport network link physical QUESTION 2 OF 8 B source port: ? dest port: ?

In C/C++ network programming; create a simple web proxy that handles the connection between a client and server. I currently have been working on a client and server echoing each other from the geeks for geeks example but can't find much information in CODING up a web based proxy. I do understand the type of proxy to create but do not understand how to code one up in terms of client-proxy-server connection through https. The answer that I am looking for is how to create the web proxy in C. You can use the geeks for geeks example (client/server) or use one of your own.
Solve this Question? Write a Java program to create a TCP Socket program to receive an input message from client socket, reverse the input message and send it back to the client. Note that the program should have the comments embedded in it to explicitly explain why that code is being used. Explain in detail the client process and the server process with reference to the code given by you for this task.
Computer Network LAN Network Topology Image. the image below Use the image as a reference, if the values are A, B, C and D (3rd octet) with the following conditions: Value A = 29 Value B = A + 1 Value C = A + 2 Value D = A + 3 x1, y1, z1 are the interfaces for the router gateway, while x2, x3, y2, y3, z2, z3 are for the router interface a. Find the Routing Table R1, R2, and R3 using the following table! Destination Next hop Interface b. With the Routing Table that you have specified in point a, which path will PC1B take when communicating with PC2B and PC3B c. In theory there is a routing table for Network Address 0.0.0.0 with a Subnet Mask of 0.0.0.0, explain the function of this routing table?
java, please solve the questionnnn quickly
Hello. I need help developing a C or C++ program that simulate an 8-port Ethernet switch. The switch initially has no knowledge about the hosts connected to each port. It learns frame addresses and stores-and-forwards the frames. The input text file "in.txt" contains information of the incoming frames, one frame per line. There are 4 pieces of data per line: frame ID, arrival port, frame source address,and frame destination address. The frames arrive at the switch in the order of which they appearin the input file. Destination address "X" indicates a broadcast frame. Thank you! ********************PLEASE YOUR CODE MUST BE COMPLETE, COMPILE AND EXECUTE**************** The output text file "out.txt" has 8 lines. Each line lists all the frames departing from each port, here is an example: "in.txt" contains 5 incoming frames:F1 P2 B--AF2 P6 D--CF3 P5 E--BF4 P7 F--DF5 P6 D--X"out.txt" should list the departing frames on each port:P1: F1 F2 F5P2: F2 F3 F5P3: F1 F2 F5P4: F1 F2 F5P5: F1…

Write a MultiThreaded ServerSocket Program in C# that can handle multiple clients at the same time. a C# Server Socket use TcpListener Class and listen to PORT 9393. When the C# Server Socket gets a request from Client side, the Server passes the instance of the client request to a separate class handleClient. For each Client request, there is a new thread instant is created in C# Server for separate communication with Client.

Write a script using PHP that takes a link from the user and parses through its associated web page to print a list of every link embedded on that site. This program must work recursively, so for each link that gets printed, the program should automatically take each of those links as a new input and do the same for them until there are no more links left. If the same link exists twice on the same page, or if it exists on more than one page, the program should ignore all duplicate instances of the link.
Prior to this conversation, we said that each thread in the JVM was only allowed to use one method at a time. What about this scenario causes you to think this way?
