direction of pkt-flow not specified, sending pkt up on stack on default (CRCN + NS2)

abrartunio · 12-17-2016, 11:28 AM

Dear all

I am using centos6.5 with CRCN patch
Everything is running fine except that when I increase number of nodes from to 20 with WCETT and MACNG protocol. I get this warning / error as " direction of pkt-flow not specified sending pkt up on the stack by default and segmentation fault.

Later on this segmentation fault was removed by modifying connection and number of flows in .tcl file. But the other warning still remains.

An immediate help would be highly appreciated as I am running out of time. Plz

I am not knowledgable about NS2 so cannot provide an answer of my own.

However, as no one else has stepped up, I did a quick internet search for the error message...

Code:

direction of pkt-flow not specified sending pkt up on the stack by default

...which turns up plenty of hits.

I cannot recommend one for you but would suggest that you look through the search results available from your search engine of choice as the quickest way to find an answer to your specific problem.

Good luck!
