Hi all, I've been looking through the various qos/cos options available, my particular area was in how IP (MPLS perhaps) compares and can be a substitute for ATM. Well, theres lots of talk and hype out there, from simple IP queuing eg cisco priority queuing, rsvp, diffserv, mpls traffic engineering etc But two things are bugging me.. 1. To what extent have providers implemented QoS for their customers 2. Hype aside, to what extent do customers actually want this (and by this I dont just mean that they want the latest QoS because its the 'latest thing', there has to be a genuine reason for them to want it). And this takes me back to my ATM reference where there is a clear major market still out there of ATM users and what would it take to migrate them to an IP solution? Also, how are people implementing bandwidth on demand (dynamic allocation controlled by the customer) solutions to customers Cheers Steve -- Stephen J.
