[ns] The Finding and the uncertain in MPLS routing simulation by MNS2.0

[Bo Peng]

Dear all,

I am doing simulation about routing in MPLS/IP network by MNS2.0. What I am
trying to do is to find out the mechanism of control part of routing and
evaluate the performance. I use the constraint-routing approach and DV
algorithm. I have got some good results and seen clearly the route is chosen by
the available resource and dynamic re-compute the new route when resource
changed by release the path.But there is still something I do not understand,
like the trigger update mechanism and frequence and the relationship between
the TE_DB(I have read the the MNS code and it seems use this as the resource
database).

So if someone is also doing the MPLS simulation or interested in this, I wish we
can talk about this and try to finger something out together. I think we can
benifit each other by discussing it.

I am looking forward to hear from you soon.

Cheers,

Bo Peng
