Hello,

I want to create simulation of network with using cisco routers with their
access lists. I decided that particular access list of routers I would store
to particular node. If I understand working of NS correctly I can catch
incoming packet for some node in:

classifier.cc in
void Classifier::recv(Packet* p, Handler*h)

Incoming packet has header. There is prev_hop (it could be actual node) in
packet header.

hdr_cmn *cmnh;
cmnh = hdr_cmn::access(p);
prev_hop = cmnh->prev_hop();

Bui If I use it it still return 0

Please, could you help me? Or could you tell me another way, how I can get
id of actual nonwireles node.

Thanx a lot

Jiri Macku

Dear all,

We have to implement M/M/m queueing system (eg m = 5 servers), with no buffer
, lamda = 400 and mu = 10ms.

Should we keep the Queue_limit ZERO or ONE for NO_BUFFER case here? We doubt because this gives all the packets (100%) dropped, while making the Queue_limit 2 (and more) reduces the dropped packets to less than 16%. 

Note: We used array of nodes for multiple servers and used array of UDP agents to attach with each of them.

Will be thankful if someone can give a little hint on where we mistake!

regards,
Mayur
