The authors advocate the notion of Service Overlay Network (SON) as an effective means to address some of the issues, in particular, end-to-end Quality of Service (QoS), plaguing the current Internet, and to facilitate the creation and deployment of value-added Internet services such as VoIP, Video-on-Demand, and other emerging QoS-sensitive services. The SON purchases bandwidth with certain QoS guarantees from the individual network domains via bilateral Service Level Agreement (SLA) to build a logical end-to-end service delivery infrastructure on top of the existing data transport networks. This paper studies the bandwidth provisioning problem for an SON which buys bandwidth from the underlying network domains to provide end-to-end value-added QoS sensitive services such as VoIP and Video-on-Demand.
