Located in the northwest of Zhejiang Province and the southwest of Hangzhou, Fuyang is a famous historical and cultural city in China with the slanting Fuchun River running through the whole territory. Since ancient times, Fuyang has a fine tradition of studying inheritants and respecting teachers and education. There are 112 primary and secondary schools and kindergartens in the district, with about 120,000 teachers and students. Fuyang has been awarded honorary titles such as "Excellent Preschool Education Area of Hangzhou", "Excellent Education Area of Zhejiang Province", "Basic Modern Education Area of Zhejiang Province" and "Balanced Development Area of National Compulsory Education". Education has become a "golden card" of Fuyang. In recent years, Fuyang has rapidly promoted the construction of education informatization and promoted the balanced and high-quality development of education. In 2020, Fuyang was rated as the first batch of "Internet + Compulsory Education" experimental areas in Zhejiang Province.
With the rapid development of education informatization, Internet-based remote teaching, delivery classroom, synchronous classroom and other teaching scenarios gradually increase. Meanwhile, applications such as video conferencing, online classroom and online learning, and Internet of Things management and control also occupy network bandwidth, which requires higher and higher campus network bandwidth and performance. In 2019, Zhejiang Provincial Department of Education put forward the campus network standards of "the bandwidth of the campus network outlet of middle and primary schools in the region shall reach 2.5G, the regional education computer network shall support IPv6, and the wireless network shall cover 90% or more of the schools in the main teaching places". Therefore, in 2019, Fuyang Education Bureau began to launch the ten gigabit upgrading work of the MAN.
The upgrading of IPv4 network and the improvement of throughput capacity at the network outlet are the key points in the transformation of metropolitan education MAN. How does Fuyang Education Bureau efficiently complete the evolution from IPv4 to IPv6 and upgrade the export bandwidth in a short time to ensure the smooth construction of the project and achieve the transformation goal?
IPv4/IPv6 dual-stack gateway promotes IPv6 network construction
With the development of school information, electronic class board, face recognition attendance, multimedia teaching tablet and security monitoring probe and other terminals related to teaching are also more and more, education man needs to evolve from IPv4 to IPv6, in order to carry more network terminals.
In order to solve the problem of repeated authentication of users under IPv4/IPv6, Fuyang Education Bureau adopts Ruijie IPv4/IPv6 integrated authentication scheme. As long as a dual-stack user passes the authentication under IPv4, the user under IPv4 and Ipv6 protocol stacks can be authorized to pass the egress gateway, which greatly facilitates the authentication of users in the education network. Fuyang education MAN choose Ruijie RG-EG3000 series gateway as primary and secondary school export equipment, quickly completed the education MAN from IPv4 network to IPv4/IPv6 dual stack network transformation, this is a comprehensive upgrade of the basic network of education information, Ruijie give full play to their own advantages, promote Fuyang education MAN rapid evolution to IPv6.
The throughput capacity of network export will be increased from gigabit to ten gigabit
With the popularity of multimedia educational courseware and network teaching applications, such as synchronous classroom and delivery classroom, the network outlet traffic increases, and the requirements for network bandwidth increase correspondingly. The original gigabit outlet has gradually failed to meet the requirements of multimedia network teaching.
Ruijie RG-EG3000 series gateway fully supports 10-gigabit network, adopts multi-core MIPS CPU, has the characteristics of high throughput and low delay. Fuyang education MAN configures RG-EG3000 series egress gateway supporting double ten gigabit ports for all schools, which lays a solid hardware foundation for further enhancing network egress bandwidth in the future.
Strengthening intelligent control is in line with the requirements of the regulatory authorities
The education Metropolitan area Network connects the Education Bureau and more than 112 schools and branches under it. There are many access users and the application is more complex. In order to prevent the abuse of P2P software by users accessing the network and ensure network security, Fuyang education MAN enabled the intelligent flow control system, now running in each school exit RG-EG3000 gateway can do fine control over the flow through the school exit, automatically limit the bandwidth occupied by P2P software, automatically protect teaching courseware, Multimedia video and other application streams are forwarded first. In addition, in order to ensure a healthy teaching environment, Fuyang Education MAN strengthens the audit of users' online behaviors, automatically filters out bad websites, and the records of users' online behaviors meet the requirements of the regulatory authorities for 180 days.
After the transformation of the Fuyang education MAN, practicability, scalability, reliability and security have been significantly improved, "speed up wisdom, safety improvement" of the transformation goal is fully implemented. The high-speed, stable and reliable network will better promote the deep integration of information technology and education and teaching, and more effectively serve the education cause of Fuyang.
