Abstract
Abstract—Nowadays, the interest in using Metro Ethernet as the main access technology in Next Generation Networks (NGN) is ever increasing. One of the main demands of these networks is to provide Quality of Service (QoS) for multimedia and other time stringent applications. At present, several wellknown technologies are used by the metro Ethernet, such as NG-SONET/SDH, VPLS, and RPR, which have been used independently so far, and none of them provides QoS. ETSI TISPAN architecture is used to provide QoS in NGN. In this paper we have used three different metro Ethernet technologies, NG-SONET/SDH, RPR, and VPLS in a combination with RACS and NASS (ETSI TISPAN subsystems) to meet QoS requirement. To do so, we propose a framework which uses the mentioned technologies and TISPAN to satisfy QoS in metro Ethernet networks.
