Building High Reliable Campus Network

With the rapid popularization of the Internet and the increasing application of in-depth, all kinds of value-added services on the network has been widely deployed, network bandwidth also grown exponentially, the network interrupted a short period of time may affect the large number of business, resulting in significant losses. As the basis of business bearing the main network, its high reliability (High Reliability) has therefore become the focus of attention.In this context, from operators to large and medium-sized business customers in the construction of production networks (production network), 5 9 reliability of the network (in 2001 can not provide services in time for about five minutes), has become The pursuit of network building. For equipment providers, or solution provider, the ability to provide end-to-end high reliability network solutions, not only reflect the strength of the technology vendors, whether in the future is a matter of intense competition in the key to survival.This paper summarizes the current status of the enterprise network, the combination of practical work experience, analysis of the current enterprise network using the practical problems encountered in the proposed design of a high-reliability network the need for the park. After two basic level from the beginning on how to build a reasonably high-speed campus network.First of all designed to establish levels of thinking and achieve a core level - the distribution layer - the network access layer structure fundamentally excluded because of the irrational structure and lead to the future of the network constantly adjusted to avoid a fire-fighting team.Second of two large enterprises in the park network in the most commonly used dynamic routing protocol, EIGRP OSPF agreement and the two agreements, the analysis in the different network environment EIGRP and OSPF agreement on the corporate network and Wan peacekeeping personnel The requirement to conduct comprehensive comparison, in order to achieve the most appropriate solution.In the third part of the classification recommended by the park design a major component failure, observed that the flow of data recovery time for a record and analysis, the network aims to build or upgrade the park in the process of design, based on the assessment programme.Through this network design and optimization of enterprise network makes the stability can be a large degree of upgrading, so as to carry out normal business operations provided a strong guarantee.
