ETHERNET VIRTUAL PRIVATE NETWORK SYSTEM FOR PROVIDING FAST PROTECTION FOR ACCESS RINGS

摘要

In one embodiment, a method includes obtaining a first indication from a first source included in an Ethernet ring and obtaining a second indication from a second source associated with a provider edge (PE) node The method also includes determining when the first indication and the second indication are indicative of a direct failure of the PE node and determining when the first indication and the second indication are indicative of a ring partition failure associated with the Ethernet ring. The direct failure of the PE node is identified when it is determined that the first indication and the second indication are indicative of the direct failure of the PE node, and the ring partition failure associated with the Ethernet ring is identified when it is determined that the first indication and the second indication are indicative of the ring partition failure associated with the Ethernet ring.

1. A method comprising:
obtaining a first indication from a first source, the first source being included in an Ethernet ring; obtaining a second indication associated with a provider edge (PE) node, wherein the second indication is associated with an Ethernet Segment (ES) route; processing the first indication and the second indication, wherein processing the first indication and the second indication includes determining when the first indication and the second indication are indicative of a direct failure of the PE node and determining when the first indication and the second indication are indicative of a ring partition failure associated with the Ethernet ring; identifying the direct failure of the PE node when it is determined that the first indication and the second indication are indicative of the direct failure of the PE node; and identifying the ring partition failure associated with the Ethernet ring when it is determined that the first indication and the second indication are indicative of the ring partition failure associated with the Ethernet ring.
