hi naazira,
Well i think we have already discussed that more no of components does not necessarily mean more simulation time in the previous topic but yeah we may or may not relate simulation time with speed of network.Anyway , You mentioned of connecting components in parallel but i don’t think we actually can do it because of our requirements ( like we cannot connect fiber and amplifier in parallel and so on because it won’t serve our purpose there). There must be something which could help us in calculating speed of network but in one way or other it is related to delay associated with each component.
Regards
