Summary

Recommendation ITU-T Q.4064 specifies virtualized broadband network gateway (vBNG) interoperability testing requirements. As a background, Recommendation ITU-T Q.4064 gives an overview of the vBNG and its interoperability testing, which includes, but is not limited to, the definition, characteristics and general capabilities of vBNG. Use cases of a vBNG are provided in an appendix. Based on an analysis of the vBNG capabilities involved in use cases, the corresponding requirements for vBNG interoperability testing are introduced.
