The distribution and coordination of policies is often overlooked but is crucial to the scalability of dynamic, personalised services. In this work we partition an Abstract Syntax Tree of the policies to determine the responsibility of different management nodes in a geographically segregated network (i.e. management by delegation). This partitioning is combined with IN/OUT set analysis to determine the required coordination for policy enforcement of complex policies with inter-dependencies. Our simulation results show that this approach is promising, as higher decision loads can be readily handled by further sub-dividing of the network.
