Policy-Based Networking: Architecture and Algorithms

The Policy Management Tool

As must be apparent to you at this stage, the policies described in the section "High-Level Policies" and the policies described in the section "Low-Level Policies" of this chapter have very little in common. There exists a large gap between the business needs of an enterprise/ISP/ASP and the technologies that are required to satisfy them. Clearly you need to develop solutions that bridge the gap. One possible way to bridge this gap is by exploiting the IETF policy architecture and the policy definition framework.

Note

The policy definition framework is being done jointly within IETF as well as DMTF. Because it is network-centric, I will refer to it as the IETF architecture. The IETF does the bulk of the architecture, ...
