This Recommendation defines the network operating parameters of a flow aggregate (FA) to be exchanged among different network domains for various types of FAs in NGN, and defines the architecture for exchanging these parameters. It also defines, for informational purposes, the mapping of the transport technology specific parameters to the defined network operating parameters. The details of the protocols are for further study and are out of the scope of this Recommendation. Usage examples of the exchanged operating parameters are shown in several appendices.
