Abstract: A system that provides communication services may include two switches for redundancy. The switches may indicate that they are independent devices to upstream devices and indicate that they are the same device to a predetermined device set. If one of the switches enters an undesired state, then the switch in a standby state may modify the upstream devices to preferentially forward packets directed toward the predetermined device set to the standby switch rather than an active switch, and after transitioning the active switch to the standby state, transition the standby switch to the active state.

Abstract: A network device includes a storage and a message bus. The storage stores subscription information. The message bus distributes state information associated with a first agent to at least two agents based on the subscription information. The message bus is distinct from the first agent. The state information is stored in a data structure exclusively managed by the first agent. The message bus, after distributing the state information, makes a determination that a connection to one of the at least two agents has been closed; and performs, based on the determination, an action set to prevent attempts to distribute future state information to the one of the at least two agents.
