Chen & Yang Expires April 22, 2010 [Page 2] Internet-Draft MPLS-TP NM Auto discovery requirement October 2009 1. Introduction Layer network topology display on NMS, and can refresh quickly on any change happen on managed network, this function is very useful and important in current and future TMN. It implies equipment should provide some mechanism to support, such as auto discovery. These also apply to TMN of MPLS-TP network. Assuming server layer is exist and in working status. From NMS point of view, the following MPLS-TP specific information are expected to retrieve from network element. And any change on these information, are expected to report to NMS immediately, in spite of whether control plane is exist or not. . 2. Conventions used in this document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. 3. Information for LSP layer to be discovered From NMS point of view, the following MPLS-TP specific information are expected to retrieve from network element. - Local NE identifier - Local NE address - Local node(LSR) identifier - Local node(LSR) address - Corresponding sever layer connection point identifier - Adjacent NE identifier - Adjacnet NE address - Adjacent node(LSR) ID - Adjacent node(LSR) address Q.G. Chen & Yang Expires April 22, 2010 [Page 3] Internet-Draft MPLS-TP NM Auto discovery requirement October 2009 - Adjacent corresponding sever layer connection point identifier If connection is exist the following information on per-connection are also needed: - LSP identifiers - Local LSR identifier - Adjacent LSR identifier - Label If protection is involve, the following information on per- protection-group are also needed: - Protection group identifier - Working LSP identifier - Protecting LSP identifier - Adjacent LSR identifiers in protection group - Protection type - Current protection status 4. Information for PW layer to be discovered From NMS point of view, the following MPLS-TP specific information are expected to retrieve from network element. - Local NE identifier - Local NE address - Local node(PE) ID - Local node(PE) address - Corresponding sever layer connection point identifier - Adjacent NE identifier Q.G. Chen & Yang Expires April 22, 2010 [Page 4] Internet-Draft MPLS-TP NM Auto discovery requirement October 2009 - Adjacnet NE address - Adjacent node(PE) ID - Adjacent node(PE) address - Adjacent corresponding sever layer connection point identifier If connection is exist the following information are also needed: - PW identifiers - Local node(PE) identifier - Adjacent node(PE) identifier 5.
