Design And Implementation Of WAN Of High Availability Based On Business Classification For Coca Cola

With the further development of the enterprise information, all kinds of business are closely connected with IT inseparably. Many large enterprises have established their own data centers to realize data concentration and various businesses of their branches are operated through Data Access Center of WAN. Therefore, as a medium to provide bearer service, WAN's high availability is the key to the reliable operation of the information system. Now how to ensure the high availability of WAN and smooth implementation of all the business is important for many large enterprises to implement their information projects.This paper takes the wide link between the Hangzhou's data center of Coca Cola Corporation and its subordinate factories for example. On the basis of the network design of active and standby redundancy possessed by this company, this paper takes into consideration the small bandwidth and easy congestion of WAN in actual use as well as Coca Cola's wide variety of data services and unbalanced data traffic of big difference, improves the current situation and proposes solutions to the high availability of WAN for business segments and puts them into practice in terms of the topological routing and strategy, dependable flow, control of congestion, priority control and load balancing.The main functions of this paper:1. To take Coca Cola Corporation for example, analyze the problems existing in the WAN connectivity of the Hangzhou's data center and put forward the demand for reconstruction of WAN connectivity and establishment of WAN network connection of high availability. 2. To study implementation techniques for the highly available network and propose the planning and design scheme of WAN network for Coca Cola Corporation.3. To take the Hangzhou's data center of Coca Cola Corporation as example, test and implement successfully the projects of highly available network based on businesssegments.After this scheme of reconstructing network has been put into practice, the network performance has been improved to a great extent, the availability of present WAN for data business segments enhanced, the information process further developed and business growth promoted.The successful implementation of this project indicates that the expected effect of the design reform of highly available WAN network based on business segments has been achieved, which lays foundation for the development of Coca Cola's data center and growth of its future business.
