【摘要】：随着企业信息化建设步伐的加快，，大港油田公司整体信息化水平得到了快速发展，越来越多的生产经营、管理决策活动逐渐实现了信息化，致使企业对互联网带宽的需求和数据中心应用系统的访问急剧增加。2004年的出口带宽只有100Mb，据测算目前至少需要1Gb的带宽才能满足需求。根据本地电信运营商的实际情况，大部分带宽只能选择联通。在互联网环境中，不同电信运营商间一直存在着互联互通的瓶颈问题。在大港油田这种高带宽、多出口、且出口带宽严重不平衡的环境下，如何保证互联网访问的通畅性和安全性是本文研究的主要问题。在数据中心方面，随着重点应用系统访问量的不断增加，原有的单服务器访问模式的诸多弊端逐渐显现，如何建立完备的服务器群支撑体系，保证重点应用系统访问的稳定性与可靠性是本文研究的另一方面问题。为了解决上述企业网络中的应用问题，本文从链路负载均衡、防火墙负载均衡和服务器负载均衡三个方面对负载均衡技术进行了研究。在此基础上，设计了可靠的架构平台，定制了合理的冗余策略，提出了综合解决方案，从而构建起新的大港油田企业网络应用平台。本文对负载均衡技术在互联网出口和数据中心的方案进行了测试，测试结果表明所设计的方案已经达到了项目的设计要求和预定目标，在提升企业网络整体可靠性、安全性和高可用性方面有明显的效果。
[Abstract]:With the quickening pace of enterprise informatization construction, the overall informatization level of Dagang Oilfield Company has been developed rapidly, and more production and management activities have gradually realized informatization. The demand for Internet bandwidth and access to data center application systems have increased dramatically. The export bandwidth in 2004 was only 100Mb, and it is estimated that at least 1GB of bandwidth is needed to meet the demand. According to the actual situation of local telecom operators, most of the bandwidth can only choose Unicom. In the Internet environment, there has always been a bottleneck of interconnection between different telecom operators. In the environment of high bandwidth, multiple exports and serious imbalance of export bandwidth in Dagang Oilfield, how to ensure the accessibility and security of Internet access is the main problem studied in this paper. In the data center, with the increasing number of visits to key application systems, many drawbacks of the original single server access mode gradually appear. How to establish a complete server cluster support system, To ensure the stability and reliability of key application system access is another problem studied in this paper. In order to solve the application problems in the enterprise network mentioned above, this paper studies the load balancing technology from three aspects: link load balancing, firewall load balancing and server load balancing. On this basis, a reliable architecture platform is designed, a reasonable redundancy strategy is customized, a comprehensive solution is proposed, and a new network application platform of Dagang Oilfield is constructed. This paper tests the scheme of load balancing technology in the Internet outlet and data center. The test results show that the designed scheme has met the project design requirements and predefined objectives, and has improved the overall reliability of the enterprise network. Security and high availability have obvious effects.
