Point-to-point protection in point-to-multipoint networks

摘要

A method for protection switching in a point-to-multipoint network, the point-to-multipoint network including a first network end node connected by at least one first connection to at least one second network end node, wherein at least one protected second network end node of the at least one second network end nodes is further connected to the first network end node via at least one second connection, characterized in that as protection switching method a linear protection switching method is applied to at least one point-to-point part of the point- to-multipoint network independently from switching of other point-to-point parts, whereby a point-to-point part includes at least said first network end node connected to one second network end node. Hereby, switching only protected second network end nodes: is possible without further protocols. Further a network end node system for performing a method according to the invention and a network comprising such network end node system are provided.
