I'm looking at the following question:
If a Network switch handles 100 requests every minute and the average request duration is 250 milliseconds, compute the traffic volume at the switch in Erlang.
I worked out this:
Average call duration___
Average interarrival time
100 requests per minute
= 100 X 60 = 6000 requests per hour
Average interarrival rate = 60/6000
= 0.01 minutes = average inter arrival time
How do I convert 0.01 minutes to miliseconds??
