The Research And Design Of Enterprise Data Center Network Architecture

Today, almost all large and medium-sized institutions have established their own datacenter, along with the global competition intensifies, the data center network is becoming toocomplex, expensive and inefficient. The traditional data center network architecture needs toomuch exchange layer to solve performance problems such as low density and low platform.The number of users and the application of growth often leads to the isolated""increased equipment, but also a challenge for the security and reliability of network. So howto design a new generation of data center network architecture, which can meet the variousneeds of enterprises has become a key problem.My dissertation discusses the importance of the construction of center of network data,as well as the limitations of the traditional data center network architecture. Combined withthe enterprise overall network planning, design of the data center network architecture, inorder to adapt to the demand for high reliable, safe operation, improve the IT managementlevel. The overall design ideas of data center network architecture for the "core periphery"framework, data center network into core exchange area and business area of two layerstructure. Are divided according to each functional area network core, convergence and accessmodel of data center, and then through the network partition method can define the core areaclear and each edge function area, a single application access mainly completed within aregion, a single regional fault affects only a class of applications. In this paper, using thecurrent mainstream network technologies such as Gigabit technology, network virtualization,combined with business to business growth, data security, uninterrupted service needs, designa new generation of data center network architecture. The research results of this paper lies in the establishment of a new generation ofenterprise data center network architecture, data center network become a high performance,integration platform based on service unified exchange. Based on the data center networkarchitecture design, and enhance the security of scalability, network business, improvenetwork reliability. After testing the network architecture to meet the various needs of theenterprise network.
