Presently, there is no satisfactory model for dealing with political autonomy of agents in policy based management. A theory of atomic policy units called ‘promises’ is therefore discussed. Using promises, a global authority is not required to build conventional manabstractions, but work is needed to bind peers into a traditional authoritative structure. The construction of promises is precise, if tedious, but can be simplified graphically to reason about the distributed effect of autonomous policy. Immediate applications include resolving the problem of policy conflicts in autonomous networks.
