[ndnSIM] Network metrics for custom forwarding strategy

[Хайрулло Рустамов]

Hi all, 

I want to use link bandwidth and link delay and hop count to tell forwarding strategy to make decision when forwarding interest.
So for example if there are multiple outgoing interfaces(or next hops) for an interest the preferred interface would be the one with minimal cost (cost is a composition of those mentioned above metrics) to send.

I do not know how to get link delay and link bandwidth values.
Any advice?

Thank you for your time!
