Currently, the Graduate School of Chinese Academy of Sciences, Beijing University of Science and Technology, Fudan University, Shanghai, Tianjin University, Chongqing University of Posts and Telecommunications, Shandong University, Inner Mongolia Normal University and other 100 cities have used to provide broadband hotspot billing billing management and operation management system, the system100 College managed to build successful, can operate profitable broadband campus network.The system for the existing campus network environment, so that the user has both the management of operational objectives.Allow school leaders to solve the headache of "network to support network" problem, as the campus network operators a high flying wings.
What is the power of the urban hot spots are so great that the magic was favored by 100 universities?Let us adopt the following analysis reveal the secret.
Campus Network Problems and Causes
There is no reasonable management
Campus Network users are numerous and dispersed, highly mobile, it is difficult in the virtual world to achieve a unified network management, user identity in different schools, administrators, teachers, professors, students in each grade segment, the demand for their networkare different, their management should be treated differently, which makes it difficult to manage the addition of a depth.
Schools can ensure that the campus is not small business operators, not bad facilities, no unhealthy place, but can not get rid of bad information in the network issued.The only way is to restrict access to students so that students learn in the online classroom, while the information will not be unhealthy intrusion.The richer online resources, the realization of this work more difficult.
The evils of sharing network, is part of the campus network of users.They malignant download bandwidth, when the normal office use the Internet when not enough bandwidth, so that more users can experience the top speed of the network environment, the network turned into a small number of "net fans" of the park, network utilizationless than 40%, the campus network can not play its real value.
Operating strategy is not flexible billing
The high school to pay for the network communication costs, has become a heavy financial burden on schools.The students are still in school, almost no income, if there is no reasonable detail of the pricing strategy, students will also put pressure on their school career.
Countries earmarked to renovate the campus network and hope into a "manageable and can be operated by the campus broadband network."The completed campus network maintenance, upgrades, equipment upgrades and other school funding issues need to own.Network completed, how the cost of recovery, "to network to support network" was put on the agenda.The use of limited investment and ensure the advanced nature of the premise network, choose the best cost-effective network management and billing system, as leaders of the school concern.Multi-campus network users require flexible billing policy, billing policy needs not only to adapt to the requirements of different consumption levels, but also need to have the operation of the system leading products and forward-looking technology.Means the school can be a powerful management capabilities, flexible billing strategy to protect the campus network operations and timely cost recovery.
Many college campus network based on years of practical experience in construction, to deeply understand: the construction of the campus network, we must closely around the school's teaching, research and management, in particular, strengthen the application of all aspects of the project, not just infrastructure.At the same time, rapid technological development for network characteristics, schools can not blind pursuit of hot technology, do not blindly pursue furnishings, rather that depends on your practical needs of schools, the network size Deng factors, Heli Xuanzedangqian comparatively mature technology solves these problems.Through reasonable and careful management of restrictions and fees means to improve and reduce the burden on administrators, support students to learn.
How to ensure safety and stability of the network
Network security also includes two points.One is the security of web content.Currently internet, the network resources in different ways, reactionary websites, pornographic websites keep this side corrosion of the Pure Land school.How to prevent users not to these sites to track and record each user's online records, it has become an essential function of the campus network.The other is content and network security equipment.The current campus network users, students use the skills of a higher network, curious, network virus hard to detect, will result in a vicious attack on the device, resulting in the network can not function properly or even paralysis.
Campus need a reasonable, careful management of limited means to improve and charges to reduce the burden on administrators, support students to learn.
Effective solution
The market is such, what kind of problems arise, there will be corresponding measures to solve it.Beijing city hot spots for the campus network the current network environment and needs, its own proprietary billing management Dr.COM2033BMG broadband gateway, has successfully built for the 100 universities can operate, can be managed, profitable broadband campus network.The reason why the system favored by 100 colleges and universities, the secret lies in:
Powerful management functions
Dr.COM Broadband Billing Management Gateway can group users, individual user bandwidth management and restrictions; support for all access, all access to records the user to achieve the full statistics.Users of international group of the most advanced management.Can be based on network protocol, application ports, bandwidth allocation, IP and MAC address and other information detailed and orderly management.For the implementation of internal user group account management, available online date for the use of time, the use of time and flow limit upload bandwidth, filter tables, the scope can access the site, specify the export settings ISP and Internet applications and limitations.
Identification based on account status, user account password and IP, MAC, access switch IP, access ports, VLAN ID, DHCP Server and many other elements of any network user is bound to strengthen the management, as far as possible to prevent theft, for teachers andStudents set up different Internet access range, permissions, download bandwidth, Dr.COM also unique to prevent unauthorized access to the user the students set up a proxy server function, eliminating the use of agents to an account of the PC with multiple PC access, and prevent the Internetexport of obstruction, while the maximum efficiency of network resources to play.Meanwhile, statistics on the traffic analysis can help formulate a reasonable online college policy.
Flexible billing operation strategy
Dr.COM broadband gateway accounting management support based on user traffic, time, time, bandwidth, network application content, billing separately domestic and foreign site, designated IP billing monthly, stored value Kau, recharge and so on more than 100 kinds of network totalcost way to satisfy all levels of the various types of users.The system also provides hundreds of users with the industry mature and effective business model for school reference.
In cost management, it can also support time, traffic accounting and monthly and stored value Kau, recharge and other billing.Specific charging methods for different groups of users can be flexibly.For example: For the students, in class, visit the designated website of charge, in the after-school Internet offer different discounts at different times, on national sites do not charge fees on overseas websites by traffic.In the dormitory fee is 30 yuan per month, net exports of education to limit download bandwidth.For the majority of teachers, Internet access by time and site constraints, the domestic sites do not charge fees on overseas websites by traffic, specify the ISP export.Flexible and personalized pricing strategy can reduce the burden of school communication costs, it will not bring too much pressure on teachers and students online, but also a reasonable deployment of resources.
Accounting Management in Dr.COM broadband gateway with the help of school students has opened the Internet to the door, through self-service module and other users can use IE browser to query their own use, the query includes: the user when the Internet, when the net, this time the flow is how much cost of the account how much money left.At the same time a powerful real-time billing capabilities Dr.COM schools and quick and convenient record of the user's online information to the school uniform query the entire network, management and analysis.When a user account falls below a certain value of money memory, the system automatically send an e-mail to the user, informing it to renewals, when the cost of the account falls below a certain value, the system automatically close the account.When the user 2 months when not in use, the system prompted by e-mail for 3 months when not in use, close the account.Dr.COM powerful real-time billing capabilities for schools to effectively eliminate the cost of overdrafts and network resource abuse, once online access to the Internet users of its stored-value card is zero when the user immediately cut off, so rational and strong operational managementfeatures easy solution to the existing campus network the second question - no flexible billing operation strategy.
Comprehensive protection for network security and stability
Developed urban hot spots are billing management Dr.COM Broadband Gateway supports multiple authentication methods such as: RADIUS, Web + DHCP, PPPoE, VLAN, Line + IP, and can be bundled with the user's IP + MAC + VLAN ID.Sufficient to ensure a variety of network environments the convenience of user authentication.There are real-time authentication, network alarms, transmission encryption to ensure the user's registration information is not illegal misappropriation of its high-performance linear transponder capacity to ensure the expansion of broadband network applications.Powerful web shield and the network packet filtering capabilities to ensure the purity and safety of the content.Dr.COM Broadband Billing Management Gateway is also able to access each user to record the, so that schools can be well documented.Dr.COM Broadband Gateway Accounting Management in Guangdong in 1999 had applied on MAN, so far done 35,000 hours trouble free operation, and has more than 2000 success stories.This is sufficient proof Dr.COM broadband billing management with superior stability and performance of the gateway.
At the same time, the system applies the international fashion NAT technology to the internal network and the Internet to achieve full isolation, to ensure the security of the internal network.Four-group of 100 domain names and IP addresses based on the filtering table, the bad sites blocked by colleges.Accounting for statistical database management server provides backup and can be left behind at the double with internal and external network management port isolation, fully eliminate the possibility of attack well with the school mail and implementation OA system interfaces; basic model can support the 4000 internal accountsmanagement, enhanced to support from 10 thousand to 1 million internal account management.This has solved the existing campus network the third question - how to ensure network security and stability.
City hot spots after 6 years of development, industry success stories for more than 2,000, the campus network solution is to enable universities to achieve national 100 "to network to support network" for the campus network to operate successfully a high flying wings!
