PONDER2

Ponder was the name of the policy specification language previously developed at Imperial College over a number of years. A set of tools and services were developed for the specification, analysis and enforcement of these policies. Thus, the name Ponder became associated not only with the language but with the entire toolkit. Ponder2 was a significant re-design and re-implementation of Ponder. Although some of the underlying concepts bear similarity to the basic constructs of Ponder the entire framework has been re-done. In contrast to the previous version, which was designed for general network and systems management, Ponder2 was designed as an entirely extensible framework that could be used at different levels of scale from small, embedded devices to complex services and Virtual Organisations.
