摘要： The SIP server deployment can be comprised of an engine tier that provides high throughput processing and a state tier that maintains SIP state data in a set of partitions and replicas. Two sites of SIP server deployments can be configured, each being remotely located with respect to the other. A primary site can process various SIP transactions and communications and upon determining a transaction boundary, replicate the state data associated with the transaction being processed, to a secondary site. Engines in the primary site can generate hints for the state replicas which can be in turn responsible for replicating the SIP session state. The replicas can choose to follow or disregard the generated hints. Upon failure of the primary site, calls can be routed from the failed primary site to the secondary site for processing. Similarly, upon recovery, the calls can be re-routed back to the primary site.

摘要： The SIP server can be comprised of an engine tier and a state tier distributed on a cluster network environment. The engine tier can send and receive messages and execute various processes. The state tier can maintain in-memory state data associated with various SIP sessions. For example, the state tier can store various long lived data objects and the engine tier can contain short lived data objects. The state data can be maintained in partitions comprised of state replicas. A load balancer can receive incoming message traffic and distribute it to the engine tier for processing. When processing a message, the engine can pull state data objects from the state tier, use the objects and push them back to the state tier after processing is complete. If one state replica is unavailable, such as during garbage collection, the engine can retrieve the objects from another replica in the partition.

摘要： The SIP server can be comprised of an engine tier and a state tier distributed on a cluster network. Engine nodes in the engine tier can process SIP messages and can read/write state information from/to the state tier. State tier can maintain state information in a set of partitions of one or more replicas which contain duplicate information. The engine nodes can be adapted to detect and report replica failures and the replicas can in turn be adapted to detect and report engine node failures. Replicas can detect faults with an engine node if the engine node fails to poll the replica for a specified period of time and can then report the failure. The engine node can detect failures of a replica when reading or writing state information and can report the failure to another replica, which can be responsible for updating the partition view to exclude dead replicas.

摘要： A SIP server can be deployed in a two-tier architecture, including an engine tier for processing of SIP communications and a state tier for maintaining the state associated with these communications. The state tier can include RAM-based replicas that provide data to the engines. Some of the SIP session state can be moved to the database in order to reduce the memory requirements of the state tier. Upon determining that a transaction boundary has been reached where the session state is steady, the state replica can save the data to the database. A hint can be received from the engine tier by the state replica indicating that the state data is ready to be saved. Subsequently, the data can be removed from the state tier by nulling out the bytes of actual data, while preserving the primary key, locking and timer information so as not to impact latency.

摘要： In an embodiment, a system for managing communications sessions is provided. The system embodiment includes a connection to a packet network that receives incoming calls. A stateful tier manages communications sessions established for the at least one incoming call. A stateless tier comprising one or more applications provides service(s) to the communications sessions in the stateful tier. One or more servers allocate and/or manage resources corresponding to the communications sessions established for the incoming calls in the stateful tier. The servers maintain the applications in the stateless tier for providing services to the communications sessions in the stateful tier.
