ITU-T - H.248.52

Gateway control protocol: QoS support packages

active, Most Current
Organization: ITU-T
Publication Date: 1 June 2008
Status: active
Page Count: 30
scope:

This Recommendation provides H.248 packages for different quality of service (QoS) support mechanisms.

The QoS class package (clause 6) defines a single property for signalling a QoS class codepoint. Such a codepoint may be correlated with a set of network performance parameters. Such parameters may be used in the area of transport resource management or admission control.

The Differentiated Services package (clause 7) defines a property to control the 6-bit differentiated services (DS) field of the IP header, as defined in [IETF RFC 2474]. The media gateway controller (MGC) can set the quality of service (QoS) for egress media flows without having to provision the media gateway (MG) with a default differentiated service code point (DSCP) value.

Thus both packages have a slightly different scope as described in the clauses below (see also Appendix II).

The General IP Header QoS Octet package (clause 8) provides an extended capability, in comparison to the Differentiated Services package, in order to address the entire 8-bit field, and enable modification of individual bits.
