Summary

Recommendation ITU-T Y.2122 specifies the requirements for flow aggregate information exchange functions (FIXF) in NGNs. This Amendment extends ITU-T Y.2122 and defines the information model for the FIXF. The information model represents the data structure of the flow aggregate (FA) table entry defined in ITU-T Y.2122. It is essential for FA information to be exchanged in an unambiguous way.
