I will try not to violate my NDA here but there is a company that is nearly finished beta testing a service (hardware based) that is designed to measure latency, delay, jitter and packet loss. The initial product is meant specifically for the core but there is an edge product in development as well. I can't tell you anything more without getting myself into trouble.

I don't know any ISPs that us it. I imagine some enterprise networks do. I played around with it in anticipation for using it to measure jitter but found it of limited usefulness because if you have to deploy a box to do localised collection of the data anyways you may as well run a better jitter probe from that unix box.

I thought I read somewhere that Cisco was planning on dropping RTR from
casually the
featuresets. Then again, I may have just imagined that.

Seconded...

I remember at one time that on-the-router measurement features were kinda frowned upon. At least that's the general feeling I got from people. Has this attitude reversed?
