[Mini-NDN] Nearest router which cached file strategy

[sepehr abdous]

Hello,

I read Chapter 4 but I still don't know how to approach it in mini-ndn.
What I exactly want to do is implementing two strategies:
Strategy 1: the content for the interest comes from the nearest node which
has cached it.
Strategy 2: lets say N nodes have cached the data I want. two of them are
chosen randomly and between these two, the data should be received from the
one with less load.

How can I approach the problem of implementing these two strategies?

Best,
Sepehr
