- Please solve it correctly and please provide explanation of your answers. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was corrupted. So the PC immediately sends an acknowledgement segment. Assume that the PC uses Selective Repeat/Reject ARQ. (d) What will be the window size of PC A after receiving only the first segment from webserver? (e)…Please solve it correctly and please provide explanation of your answers.

Suppose you have the message (NFRDFRRFFREYFDYD) that consists of 16 alphabets and you want to send it to your friend in minimum bits, so compression the bits using table. Also, type a code to compress the message. char Freq pr Code F 6 0.375 1 0.375 1 0.375 1 0.25 01 0.625 0 0.375 1 R 4 0.25 01 0.375 00 D 3 0.1875 000 0.1875 000 0.25 01 Y 2 0.125 0010 0.1875 001 N 1 0.0625 0011 16 1 symbols = [64321] p=[0.375 0.25 0.1875 0.125 0.0625); dict = huffmandict(symbols.p); 6 1 4 [0,1] [0,0,0] [0,0,1,0] [0,0,1,1] -NWAG 3 2 1
- Write a program (in JAVA) that gives the user options to encrypt and decrypt with DES and AES. The program should further offer the user to select a block mode from the options: ECB, CBC, OFB, CFB, and CTR. Your program should be able to work with any length of plaintext message.A messaging system reads message as 4-digit positive integer d1d2d3d4 and stores encoding of the message e1e2e3e4 for security reason. The encoding process is as follows: ei = (di+i) mod 3 For example, if message is 4590, the encoded message is 2101. Read any arbitrary message and display the encoded message in the following format: Original message = Encoded message = language : CNetwork
- Computer Networks : Apply the CRC method on given data dividend= 100100 and number of zero’s appended should be 1 less than divisor and divisor in this case is 1101. When there is no error When even numbers of bits are corrupted, highlights the corrupted bits. When odd numbers of bits are corrupted, highlights the corrupted bits.If the length of the sequence number space is k bits, you may want to use the Go-Back-N and selective-repeat approaches. Is there a limit on the size of the sender window that may be used?If the sequence number space has k bits, use the Go-Back-N and selective-repeat strategies. What is the maximum sender window size?
- I am analysing a pcap file using Python and wireshark. Currently, I have it counting the number of packets I would like to count the number of SYN and ACK packets with this function? My main piece of code thus far is n is an int please show me how to write the code for this.You can use both the selective-repeat and Go-Back-N approaches to solve the problem if the sequence number space is k bits in size. How large of a window can we construct for the sender?Description: You are required to implement a server program that responds to both TCP and UDP requests from the corresponding clients. The service provided by the server is simply a substitute cipher/cryptosystem. The cipher replaces one character to another based on some key. The input message (plaintext) can be of any size but composed only of small-letter (abcdefghijklmnopqrstuvwxyz). The output (ciphertext) has the same size and composed also of small-letter characters. The key is limited to 7 characters (also small-letter). You need to treat each digit as a number according to its position in the alphabet. For example, a=0, b=1, …,z=26. To encrypt a message, you add a plaintext character with the corresponding key character (mod 26). The key might be repeated to match the length of the plaintext message. In the decryption, you subtract the corresponding key character from the ciphertext character (mod 26). Again the key might be repeated as necessary. For example, if the…
