Network Analysis The early twenty-first century is broadband MAN Period of vigorous development. MAN education is education information along with our depth to start gradually formed a new field. Suzhou has been information technology education in the nation to the forefront. In order to make better information technology education services for the city, Suzhou City, Metro works actively to implement education and is committed to both Technology Application or combination of education and information processing have achieved good results, and a national model.
This stage of education MAN Suzhou Analysis
Suzhou existing seven areas and five cities (county-level cities), Suzhou Municipal Education by the guiding ideology of information technology, Suzhou is a city of education MAN Audio-visual Museum (Education Information Center) as the main center. In the seven areas and five cities to establish sub-centers, Suzhou City Suzhou City, one of the important sub-centers, with urban education bears the important task of the center of MAN. Sub-District Education Center for the phase three main exports: one is used to connect Internet, and as a center corresponding to the export of primary and secondary schools affiliated; one is used the second line of the interface that all primary and secondary schools as a focal area of the interface; also One is used to connect to the main center in Suzhou City, the interface to achieve and the main center of Suzhou and other cities and counties of the Internet.
Suzhou Suzhou Education MAN is bearing the form of telecommunications to provide MPLSVPN build broadband MAN, MAN has built a fully meshed backbone network interconnection structure, there is no line defects in a single point of failure. As MPLSVPN main packet forwarding, add labels, routing distribution completed by the PE devices, and therefore the requirements of the client access device is very low.
In Suzhou Municipal Education MAN MPLS-VPN-based architecture for virtual private network, Suzhou City, the education management system and teaching applications, and other large applications are within the special network, each school through 10/100M chain Road access MPLSVPN network. Each school network by MPLSVPN connected with the center, forming a large campus network. Visit Center resources, and through the center to access the Internet, provided by the Internet public network central unified export, to ensure system security.
To seven areas and five main nodes in the city of Suzhou, Educational Metropolitan Area as a core layer of sub-central node, and audio-visual hall of Suzhou, Suzhou City, the main center nodes of the backbone MAN level of education. Function of the network implementation process is as follows: For each region in terms of the local central node (ie municipal, district audio-visual hall node) of all primary and secondary schools throughout the region as the Internet exports. All primary and secondary schools do not have their own specialized Internet exports, can only be provided through the telecommunications lines by MPLSVPN access to their own region where the central node, and then through the central node to access the Internet, at the same time that all of its primary and secondary schools is also available through region, central node, access to the central node in other regions and the entire metropolitan area of primary education in Suzhou city center node.
Central node of each region through telecommunications MPLSVPN network access to other regions of the central node on the other, but also access to audio-visual hall of Suzhou City, the node, so that the Suzhou Municipal Education MAN resource sharing.
And audio-visual hall central node of Suzhou, Suzhou City, as the core of education information and assume an important role. It is coming to visit Suzhou subsidiary Cernet exports in all regions, all regions of the subordinate primary and secondary schools need to central node within the region through access to audio-visual museum of Suzhou central node, and then through the Suzhou Museum node access to electronic education Cernet.
Planning Urban planning and design phase
MAN Based on the Suzhou Municipal Education MAN-depth understanding of system business requirements, Ruijie light of its own products and technical characteristics, work to create education Suzhou City Metro System Solutions For the MAN system with urban education, "high extension, multi-service, high-security" boutique network.
City metropolitan planning and design phase
Education
Suzhou City Suzhou City metropolitan area using telecommunications lines provided by MPLSVPN formation MAN. The entire metropolitan area has four major components: the core metro area; metropolitan area data centers; audio-visual hall office access areas; MAN access the schools under the regional.
