Abstract:
A mechanism for synchronizing states of components in a first routing engine to corresponding components in a second routing engine is provided. In order to reduce the amount of data required to synchronize the state of the components and the time and resources required to perform the synchronization, the state-related information transmitted from the first routing engine to the second routing engine is limited to information used to build states of a subset of the components associated with the first routing engine. That subset of components is limited to those components that receive stimuli (e.g., data streams or data packets) from sources external to the routing engine. Other components on the second routing engine synchronize state by receiving information from those components on the second routing engine that received the external stimuli information.
