Abstract
Control plane technologies will play a major role in next generation transport networks. Many publications and standards claim that approaches like Generalized Multiprotocol Label Switching (GMPLS) and Automatically Switched Optical Networks/Transport Networks (ASON/ASTN) will simplify network operation and will enable new services. In this paper, an approach is presented to analyze the business processes of transport network operators. The main operator processes are mapped to the well-known value chain concepts of Porter. This allows investigating the advantages of control plane technologies from an economic point of view. This paper shows that the introduction of control plane technology affects the business of the individual operators as well as the overall value system they form as a virtual enterprise. Moreover new business opportunities are identified and two business cases are presented.
