Dual-core three-layer network system structure

Abstract

The invention relates to network system structures, in particular to a dual-core three-layer network system structure. According to the network system structure, an intranet is connected with the Internet, the intranet and the Internet are connected with a firewall, the firewall is connected with a core layer, and an access layer and a convergence layer are further included. The core layer comprises two core switches, the convergence layer comprises a plurality of convergence switches, and the access layer comprises a plurality of access switches. The two core switches of the core layer are connected with each convergence switch of the convergence layer, the convergence switches of the convergence layer are connected with corresponding access switches of the access layer, and each access switch is connected with an enterprise user. By means of the dual-core three-layer network system structure, the overall expandability of the network is good, the application need of different enterprise crowds can be met at any moment, the access quantity of concurrency users is large, information processing response time is short, the stability of the network system is high, the reliability is high, and system maintenance is convenient at the later period.

Description

Technical field [0001] The invention relates to a network system architecture, in particular to a dual-core three-layer network system architecture. Background technique [0002] The traditional single-core two-layer network architecture is suitable for general small networks, namely the access layer and the core layer. The disadvantage of this single-core network structure is that the amount of user access is small, and the processing capacity of the system is limited. Each access machine needs a physical line to connect to the core machine. The line utilization is low, and the processing capacity of concurrent user access information is insufficient. The core machine has a heavy load and needs to handle all services. The redundancy is very poor, the later maintenance is difficult, and the system scalability is low. Summary of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a dual-core three-layer network system architecture ...
