Network interworking in the IP era is largely an issue of compatibility of control layer functions and protocols. No common framework exists yet which would tie together the various mechanisms established for achieving QoS, security, mobility, etc. This paper introduces the concept of an extensible control space that can dynamically incorporate existing or new mobile networks. The wide variety of different network functionalities in to day’s networks motivates this concept; heterogeneity in future networks will increase further. Providing a common, shared control space designed with a strong and consistent architectural view provides flexibility and dynamic adaptability of control functionality. Special emphasis lies on novel features to allow networks to automatically and dynamically interconnect and reconfigure their control functionality – which we call network composition. Finally, the plans for an integrated prototype reflecting the Ambient Networks concepts are presented.
