Re: bnx2 udp multicast packet loss and jtter

The analyzer can either use the RTP definition of jitter, or it uses
its own algorithm to attempt to
mimic the RTP definition of jitter when using TS packets in UDP by
using the continuity counter.
This happens with both UDP and RTP streams. (though for unrelated
reasons UDP is usually used)

The analyzer is on a different machine. The UDP thread isn't bottlenecked at all
and the machine is only under moderate load. It also happens with many
different applications
that can serve mpegts files.

Quite frankly, I cant believe your bnx2 can be responsible of jitters
like that. By the way, check you're on full duplex mode, not on half
duplex.

You could take a tcpdump on the sender machine, to check if delays are
on this machine, or later in your network (a congestioned egress
somewhere)
