Abstract: A network control system that achieves high availability for forwarding state computation within a controller cluster by replicating different levels of table state between controllers of the controller cluster. To build a highly available controller cluster, the tables for storing the forwarding state are replicated across the controllers. In order to reduce network traffic between the controllers, fewer tables are replicated to slave controllers, which then recompute the forwarding state of the master controller in order to have a replicate copy of the master controller's forwarding state for possible failover. In other embodiments, more tables are replicated to minimize the recomputations and processor load on the slave controller. The network control system of some embodiments performs continuous snapshotting to minimize downtime associated with reaching a fixed point and replicating the state.

Abstract: A method, system and computer program product for implementing synchronization of state information in an efficient, scalable manner. A shared state server receives a request from a client device to access a scope containing state information. The scope is distributed over a partition(s) via the use of a “data grid” thereby increasing scalability. The shared state server relays the request to a data grid server responsible for maintaining the data grid comprised of an in-memory cache and partitions outside of the in-memory cache. The request includes a key associated with a value corresponding to the requested state information. The data grid server obtains the value associated with the key from its data grid and sends it to the shared state server to be relayed to the requesting client device. In this manner, the state information is stored in a scalable manner thereby improving the efficiency in synchronizing state information.
