Green Design Of Optical Transport Network Based On Physical Aware

With the rapid growth of big data services and Internet business needs, the network plan is becoming more important. Meanwhile backbone transmission network is highly demanded. The increasing number of traffic and the scale of transmission network also made more demands towards transmission network. To accommodate this change, a more high-speed, intelligent, flexible, transparent, high-quality and safe optical network is also continue growing. In recent years, China has accelerated the pace of information network construction. According to the statistics, since2000the actual growth rate of the bandwidth are more than200%. Therefore the study of new business models and network traffic patterns bring high importance to the utilization of network resources and explore new methods of network planning and resource optimization. Web development has become an important research issue and also attracted a lot of attention all over the world.The problem of physical virtual topology design is to determine which network node device should be connected via fiber optic link. We can note that the optical network is designed to be a multi-objective optimization problem, you need to consider many limiting factors. This is a multi-objective planning problem, because the designer must also consider certain performance constraints. For example:construction cost, block probability, profits, business capacity and so on. These limits are designed and the designer must consider the issues which are related to multi-dimensional.So that we could finish a network with the routing algorithm, the physical topology of the nodes and the node degree. Because the consideration of all factors is difficult, in this case we simplify the programming model and propose appropriate algorithms as soon as possible to close to the actual network conditions. In this paper, we propose a multi-objective optimization of network topology design algorithms to solve the physical network topology design problems. Take into account the physical aware and the cost of virtual topology design. We propose solutions to finish the network topology design problems.Now the operators also need a very detail network topology design requirements so effective planning and analysis for the theoretical model has important practical significance. In this paper the mainly work as follows:First, it introduces the key technology of green space planning in optical transport network, the green space planning has an important role in the optical transmission network planning was introduced, and a detailed description of the routing algorithm in optical network planning software and important function module.Second, focus on the physical damage issue, various related algorithms are given based on the different injury models. Apply the model physical damage in RWA algorithm.Third, through the simulation and the theory of the expansion planning and green space planning, combined with the physical damage sensing algorithm to make some contrast.
