Abstract


With the continuous development of the globalinformation, network are playing a more and more important part in peaple’s daily life. The continuous development of various application mode based on Ethernet technology makes enterprise informatization permeates various fields of peaple’s work. From the traditional file-sharing to a variety of OA, ERP systems, to VoIP, remote video conferencing, distributed high-end applications such as VPN system, perfect network system has become a necessary condition of normal operation of the enterprise. But most enterprises has not pay enough attention to network construction, the traditional switch-based network model is still the first choice of enterprises. In this paper, the author take a large-scale enterprise’s network requirement for an example. Through the application of network analysis, network planning, actual configuration to analytic construct a complete distributed enterprise network.This design of the enterprise internal network system to achieve the high-availability, high scalability and disaster recovery by the application of OSPF BGP, MPLS VPN, IP QoS technology and a binary-based network topology. Through the BGP MPLS VPN technology to achieve an inter-city network of the Internet; through a variety of flow control means to achieve a level of network-based virus filtering, access restriction and the message sent by features such as priority queuing; use MCE technology through a multi-VPN instance VPN networks to achieve the same under the different systems of segregation; the core of a dual hub-and-spoke network is to protect the key to the reliability of the entire network. In addition, the entire network through the use of SNMP protocol to achieve a centralized network management, network monitoring and maintenance to bring the convenience.This network system in the practical application of stable operation, the operational system of resource allocation between the rational and basic to achieve the desired goal.
