| With the rapid development of computer technology, network communication technology and information processing technology, techniques of network design are continuously updated. Utilizing the opportunity of enterprises'vigorous carry-out in information construction, combined with my own experience from participation in Core Network Reconstruction Design and Implementation of Dalian Computer School, I did a research on the application of core network design techniques to the project from the perspective of comparative analysis on network design methodology and network equipment.Based on the goals of core network system construction of Dalian Computer School, this paper has firstly made an analysis on the present network status of Dalian Computer School's old office building, combined with requirement analysis of new network and development of core network technology so as to formulate network design principles as well as complete the design proposal of network reconstruction. Two sets of design proposal about network equipment configuration are put forward through analysis on the configuration of functional module of different layers within the method of hierarchical of functional module of different layers within the method of hierarchical model and utilization of technologies such as dual-core exchange. secondly, the paper has analyzed and studied the server cluster design and network security design to formulate detailed reconstruction proposal to improve the overall system performance of load handling as well as security and stability.In view of existing computer network situation and reconstruction requirement of Dalian Computer School, the above goals has been achieved by adopting the ideal of hierarchical network design, furthermore, reasonable proposal within scalability, high availability, cost-efficiency has been put forward by comparative analysis of network equipment. |
