PROBLEM NO.2 Suppose Client A sends packet to Client B, assume there are 4 (FOUR) links in between client A and Client B Consider the given below facts give and solve question(a) and (b): The packet is 800 bytes, the propagation speed on all four links is 2.5 10m/s, the transmission rates of four links are 20Mbps, the packet switch processing delay is 3 msec, the length of the first link is 5000 km, the length of the second link is 4,000 km, the length of third link is 1200 km and the length of the last link is 1000 km. A) What is the end-to-end delay (Nodal Delay)? (2 Marks) B) Now, repeat the part (b) by ignoring processing and queuing delays if you have any. Calculate end toend delay (2 Marks) C) Now assume the link capacity as 64Mbps, calculate (Nodal delaylend to end delay/total network delay/overall network delay). (2 Marks) e. Observe the results of problem po2(part A) and part (C) and write your suggestions on to how reduce the (Nodal delay/end to end delay/total network delay/overall network delay)? (2 Marks) 0.Now for the same problem no2 assume there are 10 TDM channels in the link. Calculate end to end delay. (2 Marks) g) list all the network access technologies. Name the access technology used in your home. (1 mark)
