Abstract: According to one or more embodiments of the disclosure, a supervisory networking device in an Ethernet ring obtains identity information for each of a plurality of other networking devices in the Ethernet ring. The supervisory networking device determines, based on the identity information, a relative position for each of the plurality of other networking devices in the Ethernet ring. The supervisory networking device generates, based on the relative position of each of the plurality of other networking devices in the Ethernet ring, a load balancing configuration for the Ethernet ring. The supervisory networking device implements the load balancing configuration in the Ethernet ring by blocking a first link of the supervisory networking device for a first subset of the plurality of other networking devices and a second link of the supervisory networking device for a second subset of the plurality of other networking devices.

Abstract: Redundant Layer 2 Domain Interconnection may be provided. First, a first device in a first domain may be designated as an active device in response to the first device in the first domain negotiating with a second device in the first domain. The first device in the first domain may be connected to a first device in a second domain. The first domain may use a first protocol and the second domain may use a second protocol. Next, the first device in the first domain in response to being designated as the active device, may allow data traffic to pass between the first device in the first domain and the first device in the second domain. Then the second device in the first domain may be designated as a standby device in response to the first device in the first domain negotiating with the second device in the first domain. The second device in the first domain may be connected to a second device in the second domain. The second device in the first domain, in response to being designated as the standby device, may then block data traffic between the second device in the first domain and the second device in the second domain.
