Aaron, I have customers who are migrating from IP SLA to Y1731 PM just because of accuracy reasons. ASR9K, ASR903 & ME3600X-24CX & ASR901 offers hardware time stamping and PTP synchronization so you get much better accuracy and scale. Y1731PM will allow you to calculate 2 way delay & jitter, 1 way delay using 2 Way DMM/DMR & Loss through SLM. You can also use service activation & ethernet loopback to conduct throughput testing.

We are concerned that if/when they ask to see their sla measurements for their cell towers that we won't be looking very good Cisco Tac is telling me that pings of any type (icmp/udp/mpls pw) are not the way to truly measure the network and that I should be using CFM/OAM type stuff. I showed cisco tac a mpls pw ping test I did and it shows drops/time-outs occasionally (!!!!!!.!!!!!!!!!!!!!!!!!!!!.!!!!!!!!!!!!!!!.!!!!!!!!!!!!!!!!! etc) Tac says that this drop and the latency seen using various ipsla pings is expected since all pings are treated less than everything else and could be getting policed by LPTS (I don't know what LPTS is) What do y'all think about all this?
