ITU-T H.248.79-2012
Scope
This Recommendation defines guidelines for handling ITU-T H.248 Streams that use a packetbased network as their underlying bearer technology. Two significant points are covered by the guidelines: 1) How packets incoming into the MG are classified to a specific combination of Stream@ Termination and Context. 2) In what order different operations (usually controlled by different packages) are applied to incoming and outgoing packets. Furthermore@ this Recommendation: 3) Provides qualitative statements concerning generic processing costs on packet handling. 4) Discusses in more detail the classification and filtering of Transmission Control Protocol (TCP)/Internet Protocol (IP) traffic. ITU-T H.248.79 relates to other ITU-T H.248.x-series Recommendations on packet processing as follows. Packet classification rules (clause 6)@ packet filtering rules (e.g.@ clause 9 and [ITU-T H.248.43])@ packet address adaptation rules [ITU-T H.248.37]@ packet marking rules [ITU-T H.248.52]@ packet/traffic policing rules ([ITU-T H.248.53]@ [ITU-T H.248.76]) and packet measurement rules (e.g.@ clause 8 and [ITU-T H.248.61]) are related to this Recommendation. Other packet processing rules may also be applicable.
