[ns] Classification decision and node id

[Thanes Vela]

Dear all

The the following is the unanswered question in this forum.
Please  share your knowledge.

Classifier works on the node entry point. Each packet which is
received by the node is classified and accordingly it is either forwarded to
the port demux or next link.
My question is that:

1. Where the decision is taking place. (I am expecting  exact code in
classifier.cc or some where) ?

2. Can i access node-id (or address) from the classify function?  if so how?

Thanks in advance

Cheers
