Design And Realization Of IP Network Based On The Cluster Routing Technique

With the further development of internet, the communication capacity of internet has been quickly improved. At present, Xi'an Telecom City network uses the back-to-back cluster type, which not only limits the growth of outlet bandwidth but also increases the equipment expansion and operation & maintenance costs. The use of cluster type has solved this problem. This field has already developed some techniques. For the particularity of Xi'an Telecom City network, the system design based on the cluster type will be further studied.This essay, taking the Xi'an Telecom City network for example, and by combining the commercial objective, completes the following work:1. First of all, after making the statistic analysis about Xi'an internet users for a long time and by applying the forecast method of trend extrapolation, we design the model for forecasting and calculating the network flow. The design of this model provides the theoretical basis to the provision of network cluster system and software and hardware configuration; 2. Based on the analysis about cluster techniques, by combining the calculation results of network flow forecast model, we design the globally first "2+4" cluster type of network system, strongly support the flattening reform of Xi'an city internet, and impro(?)e the efficiency of whole city network.; 3. For the different demands of different users for business(?)s, we apply the multi-routing agreement, and design the software configuration of cluster network r uting to reali(?)e the connection of all types of users; 4. By combining the calculation results of network flow f(?)ecast, we design the hardware configuration of cluster network equipment to meet the expansion demands of network hardware; 5. Based on the network objective, we desig(?) the network testing system to test the network performance and check the reliability of desigm The techniques, systems and algorithms used in this essay have some generality and are of the reference signific(?)nce to the application of cluster techniques.The design in this essay has received the system testing and passed the commercial triai. The results indicate that, even if the user quantity increases or the user flow quickly increases, the network disposal capacity has been further improved, greatly met the urgent demands of all walks of life in the society for internet and achieved the good social and economic benefits. After implementation of this design, we successively constructed all kinds of IP business networks based on Xi'an city network and perfected the IP application.The knowledge about the routing cluster technique is very wide, and this essay only discusses the "2+m" cluster technique, and we will further study about the system control mode related to this, exchange structure and "n+m" cluster technique.
