Abstract :
As high availability requirements, new applications, and multimedia increase pressure on networks, IT is learning that adding bandwidth isn´t enough to solve traffic related problems. Network administrators must also find ways to manage network resources effectively and efficiently. Emerging policy based networking (PBN) technologies help IT ensure that network users get the quality of service (QoS), security, and other capabilities they need. Policy based networks have the intelligence, in the form of business rules, needed to govern network operations. The networks use hardware and software technologies that let IT managers prioritize access to and consumption of network resources. PBN systems will also help make it easier to manage corporate networks as they become more distributed, attach a wider range of devices and applications, and host multiple data types with different latency and reliability requirements
