Y.1541-QOSM: Model for Networks Using Y.1541 Quality-of-Service Classes
Abstract
This document describes a QoS-NSLP Quality-of-Service model (QOSM)
based on ITU-T Recommendation Y.1541 Network QoS Classes and related
guidance on signaling. Y.1541 specifies 8 classes of Network
Performance objectives, and the Y.1541-QOSM extensions include
additional QSPEC parameters and QOSM processing guidelines.
Status of This Memo
This document is not an Internet Standards Track specification; it is
