Abstract
The session-based server deployment is comprised of an engine tier that is designed for high throughput processing of communications and a state tier that maintains state information for access by the engine tier. The engine tier includes a plurality of engine nodes that process incoming messages. The state nodes contain call state, including various timers. When processing a call, an engine sets various timers in the state tier. The engine then periodically polls the state tier for any timers that have expired. Upon expiration of a timer, the timer is assigned to the corresponding engine node which handled previous communications for the call. This affinity between the timer and its respective engine provides numerous benefits, including reduced latency and more localized data access.
