Assume also that the sender uses TCP Vegas for congestion control. The following parameters were recorded at the time of transmission # k: congestion window - 9 KB; round-trip time = 0.04 sec minimum (congestion-free) round-trip time - 0.01 sec a= 200 KB/sec; and B- 500 KB/sec. What will be the value of the new congestion window (in KB) at the time of transmission # k + 1? Write the value with no units.

The ISP wants to distribute these blocks to 2600 customers as follows: The first group has 200 medium-size businesses; each needs approximately 128 addresses. The second group has 400 small businesses; each needs approximately16 addresses. The third group has 2000 households; each needs 4 addresses. Design the subblocks and give the slash notation for each subblock. Find out how many addresses are still available after these allocations.TCP connection-Server and Client connection using C.

Please provide screenshots of it's execution. 1.- client read a line of characters(data) from its keyboard and sends the data to the server. 2- the server receives the data and converts characters to uppercase. 3- the server sends the modified data to the client. 4- the client receives the modified data and displays the line on its screen. //Server.c #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <arpa/inet.h> #include <sys/socket.h> // Add header files if needed void error_handling(char *message); int main(int argc, char *argv[]) { int serv_sock; int clnt_sock; struct sockaddr_in serv_addr; struct sockaddr_in clnt_addr; socklen_t clnt_addr_size; // Declarer variables char message[]="Hello Socket Programming!"; if(argc!=2){ printf("Usage : %s <port>\n", argv[0]);…
- 4. In TCP, a receiver advertises a 2000 byte window. The sender has 2400 bytes to send. Segment size is 1200 bytes. a) Fill in the blanks below indicating the byte numbers in the TCP segments (i.e. first and last bytes in segments), acks (i.e. next byte number expected), and window advertisements (i.e. number of bytes sender can send). bytes sent=l to. b) If the receiving TCP application now reads 100 bytes, indicate the byte numbers in the next TCP segments (i.e. first and last bytes in segments), acks (i.e. next byte number expected), and window advertisements (i.e. number of bytes sender can send). ack= ack= window= ; bytes sent to _, ack= window= window= ; bytes sent= to ack= ,window=An ISP is granted a block of addresses starting with 180.100.0.0/16. The ISP needs to distribute these addresses to four groups(A,B,C,D) of customer as follows: The group 'A' has 32 customers; each needs 256 addresses. The second 'B' group has 128 customers; each needs 128 addresses. The third 'C' group has 128 customers; each needs 64 addresses. The Fourth 'D' group has 32 customers, each needs 32 addresses. Design the Network of ISP for both IPv4 and IPv6(you can choose IPv6 addresses as own) according to above conditions and find out how many addresses are still available after these allocations. Analysis network performance for both networks and take a decision which one is the best. 1) ii) iii) iv)Please solve it correctly and please provide explanation of your answers. Please answer parts g, h and i. 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. g) The second segment from webserver was corrupted. So the PC…
