  • Communication resilience in a ring network topology
    Patent number: 12355588
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for communication resilience in a Ring Network Topology. In some aspects, a top Ethernet node, implemented in a Ring Network Topology (“RNT”) that includes multiple additional Ethernet nodes, receives downstream traffic having a virtual local area network (“VLAN”) service address. The top Ethernet node can determine that the downstream traffic is destined for a given device serviced by a given Ethernet node, from among the multiple additional Ethernet nodes, that terminates a given Ethernet Ring Protection Switching (“ELPS”) group. The top Ethernet node can determine a given VLAN subnetwork that has been mapped to the given ELPS group, and transmit the downstream traffic through the RNT using the given VLAN subnetwork.
