Hi John it's not a problem of how/why the packet lose, my concern is how can we monitor the multicast traffic hence our NOC is able to see the problem before the customer... It's multicast coming from financial markets.

Is it a constant stream like voice or video or is it an intermittent feed like some sort of multicast messaging? If this is very low-rate traffic and intermittent, Juniper routers often drop the first packet because the multicast route has timed out of the forwarding table and it gets punted to the RE. If that is what is happening, there is a workaround. If you're losing traffic mid-stream, that's a different issue entirely.

I manage a network where multicast is the most important traffic and sometimes I get issue by customer where they state that some packets are lost… Does anybody have an idea or can help me in understanding a possible solution in monitoring traffic in real time manner, maybe with the use of some software or appliance or whatelse. In my idea I could monitor traffic on the source and on the destination, then with a sort of parsing understand if it’s my network loosing the packets or not… Any idea ? suggestion ? tks _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
