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： Systems and methods are provided for improving latency during message processing in a network environment via the use of SIP server architecture. The SIP server can be comprised of an engine tier and a state tier distributed on a cluster network. 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. 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. When processing messages, 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： 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.

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, 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： A system and a method for dynamic or as-needed activation of Remote Method Invocation (RMI) layer remote objects in response to a client request. Object activation allows the system to clean up or delete currently unused remote objects, and then reactivate them when a client actually needs them. An object implementation can first be created in response to a client request. The client receives a remote reference (remote ref) and an activation identifier (activation id) identifying that particular implementation. The implementation can subsequently be cleaned up or deleted during garbage collection so as to save server resources, or alternatively the object can be reused if the system is set up to maintain a pool of objects. When the client requests the same object at a later point in time, the system activates an object based on the activation ID previously received from the server.
摘要翻译：用于响应于客户端请求动态或按需激活远程方法调用（RMI）层远程对象的系统和方法。对象激活允许系统清理或删除当前未使用的远程对象，然后在客户端实际需要时重新激活它们。可以首先根据客户端请求创建对象实现。客户端接收远程引用（远程引用）和标识该特定实现的激活标识符（激活标识符）。随后可以在垃圾收集期间清除或删除该实现，以便节省服务器资源，或者如果系统设置为维护对象池，则可以重新使用该对象。当客户端在稍后的时间点请求相同的对象时，系统将基于先前从服务器接收到的激活ID激活对象。

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.
