Abstract: The invention concerns a method of synchronizing a distributed system comprising a server (2) having a master data base (21) and a set of clients (31 to 35) having respective client data bases (41 to 45), as well as a server and a computer program product for executing this method. The client data bases (41 to 45) are incrementally updated from the master-data base (21) of the server (2). A trace of transaction (22) is maintained at the server (2) for recovery. The server (2) synchronizes the client data bases (41 to 45) in case of a failure by coordinated rollback transactions from the trace (22).

Abstract: The invention concerns a method of providing service data towards a set of two or more network elements (31 to 35) of a telecommunication network (1), as well as a service provisioning system (2) and a computer program product for executing this method. The service provisioning system (2) receives a plurality of change requests for said service data, the change request concerning one or more of the network elements of the telecommunication network (1). The service provisioning system (2) analyzes the dependencies of two or more received change requests and/or corresponding network elements specific update requests with respect to service data. Then, it aggregates independent change requests and/or update requests and transmits one or more concurrent update commands that force a parallel execution of the aggregated change requests and/or update requests to one or more network elements of the telecommunication network (1).
