Assignment 1, Question 1 Question 1 (30 marks) — Subnetting You work as a junior network administrator and you have been tasked by the senior network administrator to devise a subnetting scheme for two of the company’s internal networks. Presently, the company owns the 188.8.131.52/8 network. The two sites you are required to restructure are the 184.108.40.206/20, and the 220.127.116.11/17 networks. Subnetting task #1 [15 marks] Devise a fixed-length subnetting scheme that divides the 18.104.22.168/20 network into four (4) subnets. You should assume that the all zero’s and all one’s subnets are not usable. Subnetting task #2 [15 marks] Devise a fixed-length subnetting scheme that divides the 22.214.171.124/17 network such that each subnet can support a minimum of 1023 hosts. You should assume that the all zero’s and all one’s subnets are usable. Required information You answer must include network addresses, broadcast addresses, netmask, and the maximum number of hosts supported per network, both before and after subnetting for each subnetting task. Assignment 1, Question 2 Question 2 (30 marks) — Protocols Investigate the application protocol SIP and answer the following questions: [5 marks] Briefly describe the application architecture of SIP. (Your answer should include an explanation of why you think that this application architecture was chosen by the protocol designers)[5 marks] How is payload data represented by SIP?[5 marks] Briefly describe the format and operation of the addressing scheme used by SIP It is very rare for a single protocol to be able to operate without assistance from other protocols in order provide all the functionality required by an application. These other protocols could be at the same, or different layers of the protocol stack. [5 marks] What other network protocol(s) does SIP rely upon in order to function?[10 marks] What is it that these other protocols provide that is essential for the operation of SIP?
