Summary

Recommendation ITU-T Y.2320 provides requirements for virtualization of control network entities (VCN) in next generation network (NGN) evolution. The support of virtualization capabilities in NGN evolution – i.e., the application of virtualization techniques to NGN – enables a virtualized running environment (for control network entities) in NGN evolution.

The requirements provided in this Recommendation include the requirements of virtual infrastructures, virtualized network entities, and VCN management systems.

These requirements are built upon the virtualization scenarios provided in the appendix.
