In this paper, we propose the use of QoS routing to enhance the support of IP Telephony. Our proposed scheme is based on QoS intradomain OSPF routing, an extension of the conventional OSPF routing protocol. A DiffServ model is used (no per flow signaling, nor per flow accounting at intermediate nodes). Processing O/H is shifted from core to edge routers, which compute routes, monitor QoS path quality and enforce Call Acceptance Control (CAC) using the link state information advertised by OSPF… CONTINUE READING
