RFC2544 isn't great for non-lab testing - Y.1564 is the way to go (unless you want to validate TCP throughput rather than or in addition to L2/L3, in which case RFC6349 is the right tool). It's worth digging into what you're actually looking to test and assure - CIR? EIR? Do you need to prove burst characteristics, QoS/CoS etc? VLANs, multicast/IGMP? Some of this will determine how you'll have to test. Realistically there's a lot of kit out there for multiprotocol Ethernet service assurance, and while the MXes can do TWAMP and such just fine I'd be looking at dedicated hardware for Y.1564 et al. Apart from anything else, having performance measurement endpoints/devices dedicated to just that makes isolation of variables easier when diagnosing performance faults and gives you a bit more flexibility in how you deploy test endpoints. For 1G and up, EXFO, Viavi and VeEX all have products worth looking at, though only the former two have "service assurance" platforms specifically aimed at turn-up testing (AFAIK - VeEX has a lot of stuff in the HFC world, less so on pure Ethernet). Below 500M or so there's more scope for cheap and cheerful options like perfSonar/iperf/bwctl and friends, but I'd really avoid those if you can - we see a huge amount of variation in test performance above even a few hundred megs. -- Cheers, James Harrison _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
