Policy-based networking is the new frontier in networking. A high-level directive given to the network at a single console, it promises easy management of critical network elements such as security, Quality of Service, and device configuration. The translation of high level policies into the device specific configurations is a complex procedure, requiring detailed knowledge of the topology and routes in the network, and translation-enabling algorithms. This book would take the mystery out of this process, allowing you, the network engineer to build policy support into your network architecture. Only scattered pieces of the solution can currently be found in various IETF and DMTF working groups, or in some research presentations and workshops. In-depth understanding of the algorithms behind policy-based networking is necessary for network engineers/architects who want to create new products/applications that deliver policy features.
