Policy Based SLA Management in Enterprise Networks

The Differentiated Services Architecture defines the mechanisms that are needed to offer multiple classes of services in an IP network. While this model offers significant scaling advantages over the signaling-oriented approach of Integrated Services, the management of a differentiated services network remains a complex problem. Since the operation of a differentiated network involves numerous access routers, core routers and servers, a consistent operation is difficult to achieve by independently configuring each device. In this paper, we explore a scheme to enable a network administrator to manage and configure DiffServ networks from a central location and also away the specific details of device configuration, and allow him/her to express the management of the network in terms of application-oriented performance metrics. This leads to a simplification of network management task, which can be exploited to support business needs of an enterprise network, such as honoring Service Level...
