Assignment: Internet Technology
Question 1
In a network with an 8-layer architecture and protocol hierarchy, applications generate messages of length M bytes. Assuming each layer has a different header size: 20-byte, 20-byte, 20-byte, 100-byte, 30-byte, 20-byte, 40-byte and 150-bytes for Layers 1, 2, 3, 4, 5, 6, 7 and 8 respectively: What fraction of the network bandwidth is filled with headers? Show your calculations and briefly explain.
Question 2
The performance of a network application is influenced by two major network characteristics: the bandwidth of the network (number of bits per second that the network can transport) and the latency (the delay experienced by a bit travelling over the network). Identify the requirements of the following applications in terms of bandwidth and latency, and then give an example of a specific network technology that is suitable to use for each of these applications:
1. File transfers between Melbourne and Germany
2. Video streaming to a large remote area with many users near Broome, WA
3. Connecting a large number of real-time low data transmission requirement sensors for critical event notification such as a set of sensors in a house or car
4. Transferring a large file from local computer to a local server.
Format your assignment according to the following formatting requirements:
1. The answer should be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides.
2. The response also includes a cover page containing the title of the assignment, the student's name, the course title, and the date. The cover page is not included in the required page length.
3. Also include a reference page. The Citations and references should follow APA format. The reference page is not included in the required page length.
