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, 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.

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 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： A clustered enterprise distributed processing system. The distributed processing system includes a first and a second computer coupled to a communication medium. The first computer includes a virtual machine (JVM) and kernel software layer for transferring messages, including a remote virtual machine (RJVM). The second computer includes a JVM and a kernel software layer having a RJVM. Messages are passed from a RJVM to the JVM in one computer to the JVM and RJVM in the second computer. Messages may be forwarded through an intermediate server or rerouted after a network reconfiguration. Each computer includes a Smart stub having a replica handler, including a load balancing software component and a failover software component. Each computer includes a duplicated service naming tree for storing a pool of Smart stubs at a node.
