Measurements of Ason/Gmpls Connection Control Layer Performance According to Etsi Methodology

摘要

Measurements of performance have always been crucial for the evaluation of telecommunication systems, especially for implementation of network control elements responsible for connection handling which regards to bandwidth reservation, modification and release. That problem also arises in the Automatically Switched Optical Network/Generalized Multiprotocol Label Switching (ASON/GMLPS) architecture, which is considered as one of the components of Next Generation Network (NGN). The European Telecommunications Standards Institute (ETSI) proposed a universal methodology of telecommunication control elements performance measurements, which can be also adopted to investigation of an ASON/GMPLS connection control layer. In this paper the application of the ETSI measurements methodology with regard to ASON/GMPLS performance is described. The implementation of a laboratory testbed as well as executed performance measurements according to the ETSI methodology and their results are presented.
