Abstract
A secure tiered, robust, and deterministic converged communications architecture with the capacity to support a plurality of power distribution automation devices/components with fiber-enabled fail-over protection is described.
Claims27
A method comprising:
- receiving, by a network node associated with a first communication path comprising a plurality of first network nodes and a second communication path comprising a plurality of second network nodes, an indication to switch network traffic from the first communication path to the second communication path based on a fault detected in the first communication path, wherein the plurality of first network nodes comprise a power distribution automation device, an optical line terminal device, a gigabit switch, a smart grid service, and a utility management device;
- and
- based on the indication, transferring a connection from the first communication path to the second communication path.
A system comprising:
- one or more first network nodes associated with a first communication path, the one or more first network nodes comprising a power distribution automation device, an optical line terminal device, a gigabit switch, a smart grid device, and a utility management device, and wherein the one or more first network nodes are configured to:
- determine a fault associated with the first communication path;
- and
- send an indication to switch network traffic from the first communication path to a second communication path comprising one or more second network nodes;
- and
- a network node associated with the first communication path and the second communication path, configured to:
- receive the indication to switch the network traffic from the first communication path to the second communication path;
- and
- transfer, based on the indication, a connection from the first communication path to the second communication path.
