>         Author(s)       : B. Briscoe, et al.

>Pre-Congestion Notification (PCN) builds on the concepts of RFC 3168,
>"The addition of Explicit Congestion Notification to IP". However,
>Pre-Congestion Notification aims at providing notification before any
>congestion actually occurs. Pre-Congestion Notification is applied to
>real-time flows (such as voice, video and multimedia streaming) in
>DiffServ networks. As described in [CL-ARCH], it enables "pre"
>congestion control through two procedures, flow admission control and
>flow pre-emption. The draft proposes algorithms that determine when a
>PCN-enabled router writes Admission Marking and Pre-emption Marking
>in a packet header, depending on the traffic level. The draft also
>proposes how to encode these markings. We present simulation results
>with PCN working in an edge-to-edge scenario using the marking
>algorithms described. Other marking algorithms will be investigated
>in the future.
