I guess it could be nifty to offload this to NPU, and probably most modern NPU like EZchip and trio could do it. However it is unclear to me what are the benefits, ICMP does not provide one-way delay measurements, for this you'd need to have IP SLA and timestamping in hardware, this is seems much more useful goal to me. If for NMS purpose you wish to measure customer experienced quality and you don't care about one-way delay/jitter, you can already today 'loop' packets in hardware via given destination router, by jumping between VRF/VRF or VRF/global table. So NMS would send ping packet out, and would receive it on another VLAN, router would hardware switch it delivering realistic delay/jitter measurements. -- ++ytti _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
