摘要： A SIP server can be distributed over a cluster network and handle the processing of various SIP communications. A Diameter protocol web application can be deployed on the engine tier of the SIP server for enabling communication between the SIP server and an HSS. A profile service API can be provided that allows applications running on the SIP server to access user profile data stored on the HSS. The applications can also be allowed to subscribe to notifications about changes to the user profile data on the HSS. An Sh interface provider can be deployed on the SIP server for generating and responding to Diameter command codes. SIP servlets can access the user profile data in the form of an XML document.

摘要： The Session Initiation Protocol (SIP) server can be comprised of an engine tier and a state tier distributed on a cluster network environment. The engine tier can send, receive and process various messages. The state tier can maintain in-memory state data associated with various SIP sessions. Various applications can be running on the engine tier. A new version of an application can be deployed alongside the old version, simultaneously running on the SIP server. Incoming messages for new calls can be directed by the SIP server to the new version of the application. Incoming messages for previously established calls can be directed to the old version of the application. Once the old version is finished processing calls, it can be undeployed.

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.
摘要翻译： SIP服务器可以由分布在集群网络上的引擎层和状态层组成。引擎层中的引擎节点可以处理SIP消息，并可以从状态层读取/写入状态信息。状态层可以在包含重复信息的一个或多个副本的一组分区中维护状态信息。引擎节点可以适应于检测和报告副本故障，并且副本可以依次适应于检测和报告引擎节点故障。如果引擎节点无法在指定的时间段轮询副本，然后可以报告故障，则副本可以使用引擎节点检测故障。引擎节点可以在读取或写入状态信息时检测副本的故障，并可以将故障报告给另一个副本，该副本可以负责更新分区视图以排除死复制。

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, receive and process various messages. The state tier can maintain in-memory state data associated with various SIP sessions. A near cache can be residing on the engine tier in order to maintain a local copy of a portion of the state data contained in the state tier. Various engines in the engine tier can determine whether the near cache contains a current version of the state needed to process a message before retrieving the state data from the state tier. Accessing the state from the near cache can save on various latency costs such as serialization, transport and deserialization of state to and from the state tier. Furthermore, the near cache and JVM can be tuned to further improve performance of the SIP server.

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 environment. The engine tier can send, receive and process various messages. The state tier can maintain in-memory state data associated with various SIP sessions. The SIP server can support converged HTTP and SIP modes of communication. An application session can be established for allowing the association of an HTTP session with a SIP session such that data can be exchanged between them. This association can be broken and reestablished with new application sessions such that various SIP and HTTP clients can join and leave new sessions. An API can be provided to enable various associations and method calls for the application session.
