There's a world of difference between "sell" and "actually provide". IMHO, QoS is sold by many networks, but not actually provided (at the router). What IS provided is a system to give the QoS paying Customer credit if they A) notice they didn't get the quality of service their contract specified, and B) they request a credit. jc
Sprint Labs has some data from the real world. http://www.sprintlabs.com/Department/IP-Interworking/Monitor/ They are very careful researchers and don't make brash statements, but my reading of their research is not much support for QOS in a backbone. However, QOS may have a place on access links.
You are talking standard SLAs tho right? Guarantee 0.001% packet loss, RTT Xms between points on your network.. etc. I was interested in traffic engineering, ATM/Frame PVC style. RSVP, MPLS TE, diffserv and all that good stuff, of which I had no responses of people using it and selling them as services. Steve On Sat, 13 Jul 2002, JC Dill wrote:
