摘要： Certain aspects of the present disclosure provide a method of operating a service provider network node in a service provider network, comprising: establishing an interface between a control plane processing part and a data plane processing part for routing of control packets at the data plane processing part; at the control plane processing part, generating a control packet for routing through the service provider network; and at the control plane processing part, sending the control packet to the data plane processing part via the interface, to cause the data plane processing part to route the control packet through the service provider network using the one or more routing tables maintained by the data plane processing part in response to receiving the control packet from the control plane processing part via the interface.

摘要： A system and method of operating a network node configured as part of a link aggregation system. The system includes a plurality of first network nodes and a plurality of second network nodes for providing connectivity to first and second networks respectively, and a plurality of links between the first network nodes and the second network nodes. The network node is configured as one of the first network nodes.The network node may be set in one of an active operation mode and a standby operation mode based at least in part on a comparison of a priority with one or more received priorities. The priority may be based on connectivity to an active second network node or links available for selection. The network node may determine that it is isolated from the first network and indicate that isolation in control messages sent to second network nodes.
