That's what I thought. Our total inbound bandwidth from upstreams is about 20G at max.. so that really is the total bandwidth... Now we are terminating about 1800 PPPoE sessions on the router as well, and have policing set on them, as well as shaping on a couple of our major downstream links.

In the past we had packet loss issues due SIP's PLIM buffer. The following docs may provide some guidance: https://www.cisco.com/c/en/us/support/docs/routers/asr-1000-series-aggregation-services-routers/200674-Throughput-issues-on-ASR1000-Series-rout.html

I mean a router without ASIC based forwarding like a Juniper MX or Nokia 7750. The advantage of the 1k is you don't need a services card for cgnat, but the large disadvantage is everything passes through the ESP processor and this often leads to disappointing results under load. >I'm not sure

Hi we see similar problems on ASR1006-X with ESP100 and MIP100. At about ~45 Gbit/s of traffic (on ~30k PPPoE Sessions and ~700k CGN sessions) the QFP utilization skyrockets from ~45 % straight to ~95 % :( I don't know if it's the CGN sessions or the traffic/packets causing the load increase,
