Did you take a look in two methods shown at the link
http://hpds.ee.ncku.edu.tw/~smallko/ns2/Evalvid_in_NS2.htm<http://hpds.ee.ncku.edu.tw/%7Esmallko/ns2/Evalvid_in_NS2.htm>?
Others Evalvid links:

http://www.tkn.tu-berlin.de/research/evalvid/
http://www.ietf.org/mail-archive/web/dccp/current/msg02753.html
Just google it! =)
