The interest covers all aspects on NGN from the global standards, architecture and services. The management of services provided in the NGN environment has posed great challenges due to the heterogeneity of the service protocols, service requirements and specifications and service functionalities. The research proposes enhancement of the automated service management through embedding the semantic service descriptions that can be referenced to the service ontology for service creation and management into the Next Generation Network, which will become Semantic Next Generation Network (SNGN).展开更多

It involves the collaboration of several people specifying requirements that are gathered through several stakeholders. During this process, developers working in parallel introduce and make modifications to requirements until reaching a specification that satisfies the stakeholders’ requirements. Merge conflicts are inevitable when integrating the modifications made by different developers to a shared specification. Thus, detecting and resolving these conflicts is critical to ensure a consistent resulting specification. A conflicts detection approach for merging Object-Oriented formal specifications is proposed in this paper. Conflicts are classified, formally defined and detected based on the results of a proposed differencing algorithm. The proposed approach has been empirically evaluated, and the experimental results are discussed in this paper.展开更多
