MPLS Support for IntServ
MPLS support for IntServ remains undefined. The fact that RSVP can perform MPLS label distribution does not imply support for IntServ. As mentioned previously, the IntServ architecture makes use of RSVP, but the protocol signaling capabilities go beyond the IntServ requirements. However, you can find current efforts at the IETF to specify the interaction of aggregate IntServ reservations with MPLS networks. This proposal allows aggregate reservations to take advantage of the capabilities of MPLS networks without forcing those networks to provide full IntServ support. The "References" section at the end of this chapter lists reading material on the subject that currently constitutes work in progress.
