Hi,

  There's a lot of work and effort that has been put into QoS and
  QoS in MPLS networks.

  Service Providers tend to say that their backbone will never be
  congested and if it ever gets there, then, bandwidth will be increased
  and therefore no Congestion Management or Congestion Avoidance
  mechanisms are necessary. This makes Classification at the edge
  useless but we still hear that IP Precedence so and so is being used
  for this type of traffic, and another one for another type, etc...

  The question I have is are there any real Service Providers making
  use of QoS, and which part of it, and where ???

  I am not thinking of QoS over the Internet (ISPs) for residential clients
  but more for the SPs transporting corporate client networks with either
  IPSec tunneling, LAN Extension, MPLS-VPN, etc.

  Thanks in advance
  Martin
