Title: Congestion Notification Process for Real-Time Traffic
State: Active
Authors: Jozef Babiarz
Group: Individual Submissions (none)
Date: 2004-07-20
This memo specifies the usage of Explicit Congestion Notifications (ECN)
markings for real-time flows that use UDP, such as voice, video
conferencing and multimedia streaming. This memo tries to reuse as much of
RFC 3168, "The Addition of Explicit Congestion Notification to IP", as
possible. However, we found it necessary to introduce new ECN semantics for
real-time UDP flows. For real-time UDP flows, this memo describes how the
network performs ECN marking when congestion is experienced, but it is left
up to the application designers to define how end systems should react to
ECN bit marking. For illustration purpose, an example is provided showing
how ECN for real-time UDP flows can be used for admission control of VoIP
flows.
