Abstract


This thesis is based on the Panzhihua City strip , the government sector is very concentrated , their areas of jurisdiction , location away from the center of the city characteristics , learn from the successful experience of other cities set up e-government MAN decided to set up e-government MAN in Panzhihua City technically using Gigabit Ethernet technology using hierarchical design method , design ideas , so that the entire metropolitan area network is divided into the core layer , convergence layer and access layer ; two nodes in the design of the core layer , convergence layer design six nodes 190 nodes access layer design , the layers function : the core layer for high - speed backbone , network export ; convergence layer is the demarcation point between the core layer and the access layer of the network , used in the preparation of the VLAN between routing and control access between VLANs ; routing information through the core layer , convergence layer summary and then spread to alleviate the pressure of the core layer , the allocation logic network bandwidth , and to achieve QoS ; access layer to provide users with the local sub- network 's ability to access the Internet . The usual safety precautions used in network security : security system ; the application multicast technology and MAN high bandwidth network anti - virus system , intrusion detection systems , firewalls , three switches at the core features combined to achieve 6-way video signal is broadcast in multicast mode in the MAN to meet work requirements . Establish the optimization of the network indicators , and the formulation and implementation of the network optimization strategy . In this issue , the authors depth specializes in computer network technology , especially Ethernet technology in the broadband IP network technology , the need for analysis on the development of e-government and Panzhihua City e-government construction , demonstrated need for the project the proposed solution for the project , the project 's backbone network is designed , developed network security measures for the project as well as the decision-making of the network optimization program .
