Abstract
Dynamic circuit network (DCN) refers to an on-demand virtual circuit (VC) service in which a user makes a request for a circuit in advance via a Web page. On-demand Secure Circuits and Advance Reservation System (OSCARS) is well-known DCN software. All requests in DCN/OSCARS are guaranteed bandwidth. Therefore, the quality of service (QoS) can be determined by the request blocking probability (RBP). Several QoS provisioning mechanisms, such as the bandwidth allocation policy (BAP) and preemption, have been proposed in the literature in order to ensure low RBPs for high-priority users. This paper proposes the extension of path computation elements (PCEs) in OSCARS version (v.) 6, called the UP-PCE, which considers the user attributes in its computation. Our extended OSCARS with the UP-PCE can determine two mechanisms: the control of the available topology and the BAP.
