1 A Dynamically Extensible Control Space for Next-Generation Networks Bengt Ahlgren, Lars Eggert, Norbert Niebert, Börje Ohlman, Christian Prehofer and Mikhail Smirnov of various market players by defining interfaces, which allow Abstract—Network interworking in the IP era is largely an the instant negotiation of agreements. This approach goes issue of compatibility of control layer functions and protocols. clearly beyond interworking of well-defined protocols and is No common framework exists yet which would tie together the expected to have a long-term effect on the business landscape various mechanisms established for achieving QoS, security, in the Wireless World. Central to the proj ect is the concept of mobility, etc. This paper introduces the concept of an extensible control space that can dynamically incorporate existing or new composition of networks, which is our approach to address the mobile networks. The wide variety of different network dynamic nature of the target environment. The approach is functionalities in today’s networks motivates this concept; based on an open framework for network control heterogeneity in future networks will increase further. Providing functionality, which can be extended with new capabilities as a common, shared control space designed with a strong
