Paper Abstract

In this paper, we examine the QoS issues in the intelligent optical network (ION), and specially focus on the QoS implementation scheme associated with the control plane. Referring to the QoS models in IP networks, we propose the optical IntServ QoS model using in metropolitan optical networks, and the optical DiffServ QoS model using in core optical networks. The networks to support optical IntServ QoS model must deal with each traffic request for QoS assurance, then compute routes and establish lightpaths. In the optical DiffServ QoS model, core networks only accept the limited classes of QoS requests. Therefore traffic flows with similar QoS requirements from the metropolitan networks must be aggregated, and then core networks provide tunnels for them. It increases the scalability of networks. In the end, this paper presents the generalized control plane architecture of the node in ION, which is based on extended GMPLS and able to guarantee subscriber’s QoS using two optical QoS models.
