Re: [ns] packet sequence

[mike lui <jhc8459@yahoo.com>]

Hi Kun-Chan

Thank you for your comment
It's multicast group address, tcl code related to this
part is
set groupAddr [Node allocaddr]
set groupPort 7654

but I have no idea which part is causing every packet
sequence to be -1, Is there any part  I should check
to correct it?

Thanks
Mike Liu
