weighted fair queuing service

georgealamMember

hey guys,

i have came accross this question when i was studying for one o0f exams but i couldnt figure out how to do it.

it says:
Consider the figure below. Assume weighted fair queuing (WFQ) service. Assume that oddnumbered
packets are from class 1, and even-numbered packets are from class 2. Class 1 has a
WFQ weight of 2, while class 2 has a WFQ weight of 1. Note that it may not be possible to
achieve an idealized WFQ schedule, so indicate why you have chosen the particular packet to go
into service at each time slot. For each packet what is the delay between its arrival and its
departure? What is the average delay over all 12 packets?"

does any one have an idea on how to do this?
i have attached the diagram to this post
