Summary

Recommendation ITU-T F.746.4 describes the scenarios and requirements for deployment of information-centric networks (ICNs). The deployment supports flexible methods for deploying various ICN instances on a single network service provider (NSP) network, deploying an ICN instance over multiple NSP networks, and interoperating between different ICN instances. The framework requires decoupling of the data plane and the control plane; in addition, one or more switches and controllers supporting such deployment are required. The software and hardware resources in the switches and controllers are required to be virtualized and to be used to create ICN instances. There exist appropriate inter-ICN service provider interfaces to facilitate interoperations of two ICN instances.
