Integrated intelligent photoelectric mixed router

Abstract

An integrated intelligent photoelectric mixed router applies a distributed modular software and harware system composed of fine functional units and six interfaces. The wane length exchange unit willfinished the business at the big grain wane length degree without delaing with the bypan IP buinsess one by one and the packet exchange unit will finished the IP packet line speed forward and together with the wave length exchange unit will finish controt by SNMP-CORBA unified network manage plane unit and GMPLS technological unified control plane unit. This invention will satify the desine of organizing IP voer WDM optical internet functions of the next generation to reduce the network layers, on hancing the avalability and reduce the setting up of broadband network to maintain the cost.

Description

Technical field: [0001] The present invention relates to a large-capacity integrated intelligent photoelectric hybrid router (referred to as optical router) with a new system structure, which combines the technical advantages of traditional electrical routers and optical wavelength routers to solve the problem of the next-generation optical Internet (IP OverWDM network) on the core nodes of the network. The large capacity of equipment (over Tbits), intelligence (control plane based on Generalized Multi-Protocol Label Switching (GMPLS) technology), robustness and requirements for ensuring multi-service Quality of Service (QoS) belong to the field of broadband network technology. Background technique: [0002] The infrastructure of the Next Generation Internet (NGI) will evolve from the current electric-dominated four-layer network to the optical-dominated IPOver WDM network (called optical Internet), and the flattening trend of the backbone network will become more and more ob...

Problems solved by technology

There are also many institutions researching optical router technology based on Optical Packet Switching (OPS) technology or Optical Burst Switching (OBS) technology, such as C.Guillemot, M.Renaud et al. in Journal of lightwave and Technology, special issue on Photonic Packet Switching Systems , an article titled "Transparent opticai packet switching: the European ACTS KEOPS project approach" published on Technologies and Techniques 1998, reported a broadcast selective large-capacity optical packet switching node equipment structure, which uses a large number of optical splitters , tunable wavelength converter, semiconductor optical switch (SOA), fiber delay line (FDL) and other new optical / electrical devices have realized small granularity optical packet (IP packet, ATM cell, etc.) large-capacity switching technology (up to T bit) , the advantage of this node device structure is that it can perform large-capacity and small-grained packet switching, but the disadvantage is that the level of network intelligence such as QoS, traffic engineering (TE), and protection / restoration capabilities has not been reflected or not well resolved. In addition, the node equipment of this type of structure is feasible in theory and technology, but in the actual development process, due to the lack of support from commercially available devices / chips, it can be said that its commercial use cannot be realized within 10 years
