Q 1. Select a route by using LD, LC, DCUR heuristic and RDM heuristic for a call R whose specifications are R =(1,A,F, B,12). Cost and delay values are specified in the brackets for the respective links. Compare the results. Assume that the call satisfies the bandwidth test
Q 2. a) An incomplete VTCSMA-L transmission status table for ? = 2 and transmission time equal to 20 is given below. Find how many calls can be sent and at what time?
