When a message is sent over the Internet. Before the message is sent, it is broken into data packets. These packets are numbered consecutively, but they are out of order during transfer over the network. In order for the messagesd to be read it needs to be sequenced. In 300 words discuss how you would sort these packets with bubble sort and merge sort algorithms, explaining why you chose these two kinds of algorithm. Use numbers to demonstrate how these...

I just need some help understanding this problem. Pointing in the right direction would be very helpful. C++ in a UNIX Environment Part1 Create a one-directional ring of pipe for N processes (N ≥ 1) Part2 Create a one-directional ring of pipe for N threads Part3 Create a one-directional ring of socket for N hosts (or all in one). You may run N processes in one host. Each process has two designated ports - one for sending and...

No, No, Yes E. Ho, hum, ha Q2 CRC vs Internet checksums Which of these is not true? A. CRC's are commonly used at the link layer B. CRC's can detect any bit error of up to r bits with an r-bit EDC. c. CRC's are more resilient to bursty...

Upload the shared pcap file (Homework5.pacp) into wireshark. HTTP In this lab, we’ll explore several aspects of the HTTP protocol. Capture packets and filter for http protocol and answer the following questions. (Hint: Apply http filer) What version of HTTP version(1.0 or 1.1) is client running and what is the version...

ND-OF-CHAPTER QUESTIONS Thought Questions 1. How do you think TCP would handle the problem if an acknowledgment were lost, so that the sender retrans- mitted the unacknowledged TCP seg- ment, therefore causing the receiving transport process to receive the same segment twice? 2-2. a) Compute the minimum number of TCP segments required to open a con- nection, send an HTTP request and response message, and close the con- nection. Justify this number by creating a table showing each message and...

The Diffie-Hellman public-key encryption algorithm is an alternative key exchange algorithm that is used by protocols such as IPSec for communicating parties to agree on a shared key. The DH algorithm makes use of a large prime number p and another large number, g that is less than p. Both p and g are made public (so that an attacker would know them). In DH, Alice and Bob each independently choose secret keys, ?? and ??, respectively. Alice then computes...
