¿µ¹®³»¿ë¿ä¾à This standard specifies linear protection switching mechanisms to be applied to MPLS-TP layer networks as described in ITU-T G.8110.1/Y.1370.1. This standard specifies 1:1 architecture and 1:1 architecture operates with bidirectional switching. APS coordination protocol is needed to align both ends of the protected domain when the bidirectional switching is used.
This standard describes the protection switching functionality for point-to-point connections. Hitless protection switching is outside the scope of this version of the standard.
