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.
