| Network intelligentialization occupies important aspect in the development of the telecommunication network. The development of optical communications have been High-speed, Large-capacity and Long-distance-oriented since20th century, however, for the optical fiber communication network which has shown sufficient transmission capacity currently, intelligent level still stay low. Now, it is a urgent need to prompt the development of intelligentialization.According to the intelligent all-optical network trends and the need of building next-generation converged services network, research on new pattern of all-optical edge-node network instruments, designed for transport of remote data and access of user services, has enhanced the ability of data processing, and achieved convergence of access data from users who scatter on the edge network, in two layers of time-scale and space-scale.The research focus on the core technique and prototype equipment of intelligent all-optical network, dedicated to meet the requirements of high reliability on the device nodes and enhancing survivability of transport network. We have realized High-speed, Large-capacity buffer for video-on-demand data utilizing prototype equipment, and reduce the duration of occupying the core network bandwidth from on-demand data flow. We also have completed construction of experimental system, to realize the demonstration of typical services and applications.The primary research innovations and achievements are as follows:Main innovations:(1) Services-driven dynamic adaptation.Our research, mainly based on10Gigabit Ethernet interface, focus on parallel processing service of Ethernet data traffic, support port parallel scheduling service, provide optical interface access, adapter IP unit, and possess parallel resource scheduling capabilities.(2) A high-speed dynamic flow balancing technique for business transfer has been proposed. When the high-speed service traffic transmitted in intelligent all-optical network exceeds the bandwidth threshold in network, the network management of upper layer automatically open another optical path for service transfer, and the service flow will be dynamically balanced to the second optical path as well.When service traffic decreased below bandwidth threshold, the network management of upper layer will turn off the second optical path, and the two braches merge into an optical path. Thus it has saved bandwidth need and improved network bandwidth utilization, furthermore, ensured high quality transfer for service traffic.Main research achievements:(1) Completion of dynamic and flexible design and realization of intelligent all-optical edge network equipment to build a network platform.(2) Build intelligent all-optical network platform, design and achieve a data flow dynamic equilibrium; forwards data based on IP address or MAC address; data forwarding based on services-driven dynamic mapping and static mapping.(3) Design and demonstrate on the network platform setup.Integrated innovation on instrument level, operation and maintenance on network level, research on applications and innovation have been executed to achieve such goal. In that, we ultimately have developed a new generation of ION transmission equipment, which is adaptive for trends of future communication network with strong market competitiveness and high-level technique.Parallel scheduling and adaptation technique has been proposed to realize parallel-resources-scheduling during multi-tasks, multi-nodes as need.The developed ION-AU prototype supports parallel resource scheduling, with Ethernet data traffic processing parallel services oriented. Each prototype supports parallel scheduling service and provides optical port access. It also have adapter IP unit, protocol support, with parallel resource scheduling capability. |
