I'm just thinking, that for an Internet edge router you might just need loads of BW -not that much pps rate, (no need for full line-rate at 64B), and not that many features (just decent flow telemetry) -unless you are doing some proactive DDoS filtering on the box -in which case you need a clever and "pps-powerful" NPU. In CP you need fast and safe BGP implementation with loads of features, something that have decent BGP error handling and speaking of CP a good CP protection. Regarding the buffers if it'll be doing just 10GE to 10GE..., well during DDoS all that traffic is mangled anyways (10x10GE->1x10GE)-unless you expect something important to arrive over the internet -like voice (in which case again you need features and decent HW implementation). So what I'm trying to say is that NCS5k with no data-plane features but loads of BW and "maybe" a decent CP (-cause it's XR-based), might be the right choice? adam netconsultings.com ::carrier-class solutions for the telecommunications industry:: _______________________________________________ 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/
