Abstract: A network device includes a first agent programmed to provide a functionality of the network device. The network device also includes a message bus, distinct from the first agent, that identifies an update associated with the first agent, the update includes differential state information based, at least in part, on a state of the first agent, the state of the first agent is stored in a data structure exclusively managed by the first agent; in response to identifying the update: identifies a second agent that is subscribed to the first agent; and performs an action set to provide the second agent with access to the update.

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.
