Testing methods for SDH-based MSTP embedded with MPLS
1 Scope
This standard specifies the testing methods for the functions, performance and network management system of MSTP embedded with MPLS, including the testing requirements and passing criteria that nodes shall meet in data plane functions, control plane functions, MPLS layer performance, L2VPN applications and MPLS layer network management technologies, etc.
This standard is applicable to SDH devices embedded with MPLS, to realize L2VPN Ethernet service and also used to test Multi-Service Transport Platform (MSTP) with unified network management system.

4 Model of MSTP embedded with MPLS
This standard defines SDH-based MSTP embedded with MPLS as a Multi-Service Transport Platform based on SDH platform, embedded with MPLS function and providing unified network management system. Its key feature is that Ethernet service adapts to the MPLS layer and then maps to SDH channel for transport, or Ethernet service adapts to the MPLS layer, then maps to the RPR layer, and then to the SDH channel for transport. MSTP embedded with MPLS shall meet the function requirements of YD/T 1238-2002, YD/T 1345-2005 and YD/T 1474-2006.
The functional block model of SDH-based MSTP embedded with MPLS is shown in Figure 1.
Note: The combination of MPLS and RPR is defined in Annex A to YD/T 1474-2006, and RPR MAC layer processing is optional during processing of MPLS layer embedded in MSTP.
Figure 1 Diagram of MSTP embedded with MPLS function
The specific functional requirements for SDH-based MSTP embedded with MPLS are as follows:
a) meeting the basic functional requirements of SDH nodes specified in YD/T 1022-1999 and YDN 099-1998;
b) meeting the basic functional requirements of SDH-based MSTP specified in YD/T 1238-2002;
c) supporting carrying Ethernet services on MPLS, and the its specific functions shall meet the requirements of Clause 5 of YD/T 1474-2006, and the adaptation of Ethernet services to MPLS layer shall comply with the requirements of Clause 7 of YD/T 1474-2006;
d) ensuring the transparency of Ethernet if MPLS carries Ethernet;
e) supporting static LSP assignment mode;
