In information driven through history, ever-changing conditions of modern school, built with the new Campus Network Contact, students and staff in real time to connect to the Internet and China Education and Research Network. Ubiquitous network era, Zhoukou Teachers College Campus Network More than 12,000 students for the school and more than 690 teachers provided a good learning and teaching conditions. Issues: network congestion be solved Campus network has two exits, one connected to the education network and another connection to the Internet. Users within the network to facilitate interaction with the external network Visit Prior to set up a Firewall As two lines of the NAT conversion, with the online teachers and students continue to rise, traffic congestion in the bottleneck, the Internet has become very slow pace. As network traffic problems, the teacher continued to reflect the students, especially slow to access certain websites, but sometimes can not open site. Especially at the network is congested, the teacher from the Internet to download teaching materials, courseware tend to spend a lot of time. In order to solve the problem of traffic on campus networks through history, decided to implement the D-Link’s all-round strategic flow control system. Solution: all-around strategy for flow control system Zhoukou Teachers College network congestion caused by a major reason is that Internet users in P2P, IM and other applications of large-scale use, all-around strategy in the implementation of flow control system, schools can not control the spread of these applications. In addition, a variety of network virus attacks the infection is spread and lead to significant consumption of network resources, the chief culprit in traditional security mechanisms and equipment to deal with it is very passive and weak. D-Link’s all-around strategy for flow control system uses the L7 application layer deep packet analysis Technology Can be accurate and efficient identification of multiple P2P applications. As the use of application specific integrated circuit chip set, the system has up to 32Gbps of network data processing capabilities, ensures that improve overall network security, without compromising the performance of network applications. By P2P applications such as control, to ensure the school’s normal application. In particular, channel bandwidth, security and features dynamic bandwidth balanced, comprehensive IP traffic to meet the export control class size and achieve a flexible management of different IP. Previously, the campus network only two lines of the NAT conversion, when congestion occurs when the IP export, just as there is no ease traffic congestion after the follow-up of access requests piled up, will only lead to a wider range of congestion. Flow control system with all-around strategy over export NAT conversion, when a NAT blocking export experience, the system can automatically switch to the other export addresses, not even in the peak flow Wang Suman feeling. As the all-around strategic flow control system uses a NAT rewind technology, the DNS redundancy. Once such a failure within the network or external network DNS DNS DNS response time than the response time within the network when the internal users can use the web, mail decile Server The public address their visit, so that network access is not affected. For the operator’s network access bottlenecks, D-Link by setting static routing, dynamic routing, policy routing, and priority of each other to realize a visit to go Netcom Netcom server lines, telecommunications lines to access the telecommunications server, the purpose of walking, greatly enhance the inter-carrier access to the bottleneck problem. Order to achieve the visual management, D-Link is also equipped with a reporter alone server, by reporter Management Software For logging, analysis, statistics, network management personnel to better rule out the network hidden for security audits, etc. ready. This also solved the Public Security Bureau for regional security, and require schools to record any online information to look at network security equipment. Effect: the network safe and smooth Round strategy through a period of flow control system uses through history, to resolve the long-troubled over their export NAT, P2P bandwidth and Internet records and so a series of long-term behavioral problems.
