Method and apparatus for using G.8031 extensions to enable coexistence of G.8031-based protection and LAG-like loadsharing for ethernet paths
View Patent ↗An Ethernet protection and loadsharing capability is provided. The Ethernet protection and loadsharing capability enables co-existence of both protection and loadsharing for an Ethernet tunnel, having a plurality of associated Ethernet paths, between first and second Ethernet switches. The first Ethernet switch receives configuration information associated with the Ethernet tunnel between the first and second Ethernet switches, and processes the configuration information for causing the first Ethernet switch to associate the Ethernet paths of the Ethernet tunnel with an Ethernet tunnel endpoint object associated with an Ethernet tunnel. The first Ethernet switch, upon receiving traffic intended for the second Ethernet switch, propagates the traffic from the first Ethernet switch toward the second Ethernet switch via at least a subset of the Ethernet paths of the Ethernet tunnel using protection and/or loadsharing.
