Abstract
This paper aims at shading some light on the concept of Service Level Agreements (SLAs) and on their usefulness in the context of the so-called Premium IP Networks. Such networks provide users with a portfolio of services, thanks to their intrinsic capability to perform a service creation process while relying on a QoS-enabled infrastructure. We will introduce a definition of SLAs and we will then focus on an actual example, namely the negotiation and management of QoS-aware Virtual Private Networks (VPNs).We believe that VPNs are a significant application due both to their importance in corporate scenarios and to the high revenues they guarantee to service providers. We will discuss the issues related to the effective SLA-based management of resources in those cases where the need arises for an entity that is capable of optimizing resource utilization in the presence of network infrastructures shared by a community of users. Finally, a novel component, named SLA Manager, that accomplishes these tasks, will be presented.
