Scope
This part of GB/T 21645 specifies the technical requirements for the E-NNI interface used in operators' ASON networks. It mainly includes E-NNI interface specifications based on OIF, such as: E-NNI signaling functions, supported services, signaling reference configurations, signaling protocols based on RSVP-TE, E-NNI routing architectures, and extensions to the routing protocol based on OSPF-TE; as well as E-NNI specifications based on IETF GMPLS, such as: inter-domain signaling architectures of IETF GMPLS, extensions to inter-domain signaling protocols, and inter-domain routing requirements. This part does not include automatic discovery and policy settings.
This part is applicable to the E-NNI interface in automatic switching optical networks (ASON) based on SDH and OTN.
