Hypothetical reliable data transfer protocol: A jumping window based Go-back-N ARQ protocol for file transfer using UDP as the transport protocol:
In this protocol, a window of size W is used. The sender continuously sends W packets corresponding to the current window, and then waits for an acknowledgement. The receiver receives W packets. If all the packets are error-free, it sends out a positive acknowledgement, say RR-i (RR: Receiver Ready). The receiver then moves its window starting from the packet with the sequence number i. Upon receiving RR-i the sender moves its window starting from the packet with the sequence number i. If a receiver receives a damaged packet (say, with the sequence number j) in its current window, it receives and discards all the remaining packets in the current window and it sends out a negative acknowledgement, say REJ-j (REJ: Reject). The receiver then moves its window starting from the packet with the sequence number j. Upon receiving REJ-j the sender moves its window starting from the packet with the sequence number j and sends out packets starting from j. Assume that the packet sequence number is in the range from 0 to 7. For each packet, 100 bytes of data is sent. Assume that a packet can be damaged according to a specified packet error probability. Ignore packet losses, ACK damages and losses. Implement the protocol, and measure and plot the throughput for different values of W (1, 2, 3, 4, and 5) and different error probabilities in the range from 0 to 0.5 in steps of 0.1. Use the random number generator to generate uniform distribution and declare a packet as damaged according to the specified error probability. Write a Report describing your implementation, how you carried out the performance study, performance graphs, and discussion on results.
Question: (a) What are the various options to mitigate risks in an Information Security Management System (ISMS)? For each option specify an instance where it can be used.
Question (a) Estimate the average throughput between two hosts given that the RTT for a 100 bytes ICMP request-reply is 1 millisecond and that for a 1500 bytes is 2 millisecon
Evaluations, Assessment, and Maintenance of Risk Controls When the control strategy has been implemented, it should be monitored and measured on an ongoing basis to determine ef

UDP ENCAPSULATION As given in the figure below, UDP packet is included in IP datagram and the IP datagram is then attached in the Frame.
Gateways They transfer packets among network machines that have different protocols (e.g. between a WAN and a LAN). They access a packet formatted for one protocol and change
