Dynamic QoS control based on VPLS in service oriented transport networks

The virtual private line service (VPLS) represents an attractive solution for enterprise customers requiring ldquotransparent LAN servicerdquo among remote sites and across a MPLS core network. In this context, the QoS enforcement is a challenge due to the high expectation of customers that require the same guarantees as a private network. This paper describes the implementation of a dynamic QoS control in VPLS scenario realized using a service-oriented network architecture for MPLS transport network, named SOON (service oriented optical network). A SOON prototype has been realized on a real metro-access testbed to experimentally validate the dynamic and self-consistent configuration of QoS-enabled VPLS and to verify QoS performances for different level of services in case of traffic congestion.
