A QoS framework for Next Generation Networks Based on Metro Ethernet
Keywords:
Metro ethernet, next generation network, quality of service, TISPAN.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 well-known 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.
