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.
