1 Scope

This section GB/T 21645 specifies the technical requirements for operators within the ASON network of E-NNI interface. Including base In the OIF E-NNI interface specification, such as. E-NNI signaling functions, support services, signaling reference configurations based on the RSVP-TE signaling Association Yee, E-NNI routing architecture, based on the routing protocol OSPF-TE expansion; and IETFGMPLS based E-NNI specifications, such as.

Inter-domain signaling IETFGMPLS architecture, inter-domain signaling protocol extensions, inter-domain routing requirements. This section does not include auto-discovery, strategies content.

This section applies to SDH and OTN-based Automatic Switched Optical Network (ASON) in the E-NNI interface.
