[ns] Mimicking The IPv6 Header Using IPv4

[SD Coulson <S.D.Coulson@scm.brad.ac.uk>]

Hello,

I am using NS for my final year project to investigate the QoS over an IPv6 
network. As I have not been able to find an IPv6 implementation I intend to use 
IPv4 to mimic the required features of IPv6. In particular I would like to know 
if it is possible to modify the 8 bit 'type of service' field in the IPv4 header 
to mimic the 8 bit 'traffic class' field in and IPv6 header. If this is possible 
are there any suggested ways of going about this.

If anyone does infact know of an IPv6 implementation then I would be grateful to 
hear from them.

Any suggestions are gladly welcome
