Abstract: Techniques for controlling reactivation of service functions are described. Implementations, for example, enable various ways of controlling and storing service objects that provide service functions.

Abstract: A service is delivered by a computer system comprising a processor, a memory accessible to the processor and computer storage. The memory holds code which defines service object classes. The service object classes are configured to provide service functions, and the service object classes are instantiated to create service objects which implement the service functions. For each service object, an associated service object identifier is generated in the memory which distinguishes that service object from any other service object. The service objects are serialized to generate serialized data, the serialized data comprising a representation of each service object, and the representation comprising that service object's service object identifier, that service object's associated state data and the service object identifier of any other service object referenced by that service object. Following deactivation, the service objects can be recreated by following the chain of references.

Abstract: Disclosed are methods and devices (e.g. servers) for establishing a real-time communication event between a user of a client device and another user of another client device via a communication network. A message pertaining to the communication event (e.g. to a communication event establishment procedure) includes multiple options pertaining to the communication event and, for each of the multiple options, a different network address unique to that option which can be accessed to select that option.

Abstract: In a cluster of servers, each server is configured as follows. A request is received at the server from a requesting entity. The request includes an identifier of the request. The server determines whether the request identifier is already associated with any of the servers in a cluster database. If the request identifier is already associated with a different one of the servers in the cluster database, it is forwarded to the different server. If the request identifier is not already associated with any of the servers, it is associated with the server. The server generates a response to the request, and, stores in local storage accessible to the server and transmits a copy of it to a requesting entity. If the request is already associated with the server in the cluster database, the server locates any response to the request that is already stored in the local storage.
