As networked systems grow and traffic patterns evolve, management applications are increasing in complexity and functionality. To address the requirements of these management applications, equipment vendors and administrators today depend on incremental solutions that increase the complexity of network elements and deployment costs for operators. Despite this increased complexity and cost, the incremental nature of these solutions still leaves a significant gap between the policy objectives of system administrators and today's mechanisms. These challenges arise in several application contexts in different networking domains: ISPs, enterprise settings, and data centers.
