The Internet is growing to the point of needing moreserious, scalable management infrastructure.Telecommunications companies and Internet ServiceProviders alike face the pressures of upgrading andprovisioning their networks while constraining theirinfrastructure costs to maintain profitability and to staycompetitive in an industry that is financially stressed withtight profit margins. In order to be financially successfulin this environment, service providers will have to supporta variety of services and applications on a combinedpacket infrastructure, carrying increased varieties oftraffic with different performance characteristics andpredictable levels of managed Quality of Service (QoS).Multi-Protocol Label Switching (MPLS) trafficengineering enables service providers to engineer theirnetworks to provide such QoS; however, this task bringsalong with it a plethora of management challenges. Thispaper discusses these management challenges and ourexperience with the design and implementation of apolicy-based management system, PECAN, for managingMPLS networks. PECAN provides the ability for anetwork operator to define high-level policies that controlthe operation of the management system. These high-levelpolicies control admission of traffic into the networkbased on the QoS guarantees required; placement oftraffic flows on MPLS traffic engineered paths; and thefeedback loop between network fault/performancemonitoring and reconfiguration of the network toalleviate the effects of any observed problems.
