¿µ¹®³»¿ë¿ä¾à The standard addresses procedure for T-SDN to construct a whole topology of a multi-domain network by discovering neighbor node automatically in the other domain network. It includes the requirements of process for a node in a domain network to discover a neighbor node in the boundary of the other domain network and data requirements by TLV(Type-Length-Value) type in the neighbor discovery protocol, LLDP(Link Layer Discovery Protocol) in the Ethernet layer. It also describes the requirements of NBIs from EMS or a node which is about notification of a discovered neighbor node and retrieval of the information of the neighbor node finally.
