Mechanisms to Ensure QoS over ASON

This paper presents an evaluation of the specifications of the QoS policies for trunk interfaces Metro and Core equipment MPLS over ASON. This paper is based in a project named "Prototype for evaluation of the costs and technical benefits in backbone networks with next-generation services based on ASON (Automatic Switched Optical Network)". The first part defines the services provided by service providers, the second part corresponds to a QoS services analysis with service level objective (SLO), then defines the QoS architecture adopted. Finally, this article presents the defined QoS mechanisms.
