On the composition of performance metrics in multi-domain networks

Despite the advances achieved by service oriented architectures adoption, data originated from measurements are still used in an isolated manner. In multi-domain network scenarios, performance information needs to be processed and related in such a way as to present more relevant results through a metric composition process. Based on recent IETF documents, this article describes a performance metric composition process implemented via software, through a library that can be integrated into diverse visualization and monitoring applications. Experiments using ESnet and Géant backbones performance data demonstrated the effectiveness of the model, the library, and IETF´s proposed approach.
