[ns] EURANE UM problem

[kamal deep singh]

Hello all,


I am using EURANE extensions to ns
(using the Patch for clean ns-2.26: ns-eurane-109.diff.gz)

I am having problem while using um mode of RLC. The problem
is that I dont see any traces when I use um.

To verify whether the script is wrong i took the example script
test_tcp.tcl from EURANE website and just changed
$ns node-config -llType UMTS/RLC/AM \
to
$ns node-config -llType UMTS/RLC/UM \
and after this I couldnt get the traces after RNC.

Is there any workaround or atleast a hint so that i can start to
look for the bug in EURANE code.

I found similar message in the mailing list:
http://mailman.isi.edu/pipermail/ns-users/2004-October/045428.html
