The network architecture where each node integrates an IP router and an OXC is an attractive paradigm for the next generation optical Internet. IP wavelength routing, which includes two types of switching and forwarding hierarchies (packet and lambda) in the GMPLS field, is based on this kind of architecture. This paper addresses the design issues of an IP wavelength router. Based on analyzing the problems and shortcomings of the previous general node structure, a novel node structure is proposed, which overcomes the problems encountered by the previous scheme. Two IP switching protocols, IFMP and GSMP, are extended to support IP wavelength routing networks. The flow classifiers, which are main components of these node structures, and the performance metrics of these structures, are also discussed.
