The blueprint of "digital campus" Campus network has become one of the necessary information infrastructures for every school. Campus network needs a high-speed, safe, reliable, scalable and cost-effective network, with perfect QOS and strong multicast support ability, and needs to establish distance education, multimedia on demand, campus card and electronic library system. In order to realize the high enjoyment and transmission of information on campus, the informationization of teaching, scientific research, logistics and management, and finally complete the design goal of "digital campus".

Tailor-made campus network solution

Campus network can be divided into small campus network, medium campus network, large campus network and inter-school communication project (educational metropolitan area network) according to its scale. ZTE has tailored campus network solutions of various sizes.

A large campus network is no less than the operator's network, and even more complex than the operator's network. The network is mainly composed of core layer, backbone layer, convergence layer and access layer, and a 10 Gigabit backbone high-speed campus metropolitan area network is constructed.

The core layer Ethernet ring network is composed of 10 Gigabit routers, which supports high-performance line-speed forwarding capability and has strong IPV4/IPV6 routing support capability. The backbone layer adopts rack-mounted, modular high-end 10 Gigabit routing switch, which has high-capacity and high-performance line-speed L2/L3/L4 switching capability. Convergence layer adopts high-performance port-intensive L3 routing switch, which supports perfect routing protocols. The access layer adopts fast Ethernet switch with fixed interface and modular interface, which has optical fiber access capability and supports L2 full-line speed switching.

Small and medium-sized campus networks have relatively few information nodes and relatively concentrated functional requirements. Gigabit/10 Gigabit backbone and 100 Gigabit switch to desktop. The key equipment design includes equipment redundancy and link redundancy. Provide perfect Qos service quality assurance function. You can also use Layer 3 switches for department aggregation.

Education MAN can use Gigabit or 10 Gigabit as the core of the network to improve the throughput of the whole network. The core backbone network of the Municipal Education Commission adopts high-performance, rack-mounted and modular high-end routing switches. According to the actual material resources and geographical distribution, schools are connected with people in different ways.

ZTE's "Digital Campus Scheme" has distinctive features.

ZTE's campus network solution has distinctive features.

Features 1: Flexible operation mode

* Have a perfect 802. 1x access solution: support the anti-proxy function; Users are prohibited from changing IP address attributes without permission; Support online authentication function based on time period.

* Support multiple access modes: have access capabilities such as PPPoE, DHCP+WEB, 802. 1x, private line fixed IP access, WLAN wireless access, VPN access, etc.

* Support flexible billing strategy: support multiple billing methods such as monthly subscription, subscription with limited duration, subscription with limited duration, prepaid duration, prepaid traffic, real-time deduction, card business, capping, value-added services, etc., and support delayed billing on holidays.

* Provide humanized self-service platform, providing password modification, balance inquiry, online record inquiry, online recharge and other services.

Feature 2: Safe, reliable and multi-service network.

* Perfect Qos guarantee. Support L2 ~ L7 complex flow classification, multi-policy based priority and CAR function, three-color bandwidth guarantee, traffic supervision and traffic shaping, multiple congestion management and congestion avoidance algorithms, flow mirroring, traffic statistics and SFLOW, to ensure the normal and stable operation of teaching and management.

* Reliable security. Support port binding and user address number limitation, support perfect ACL and VLAN isolation function, prevent users from connecting to DHCP server privately, prevent IP address conflict and IP address theft, and provide functions such as user port reverse inspection, reverse tracking and online information tracking. Configurable hardware firewall, with good anti-virus and anti-attack ability.

* Support network-wide multicast capability; Support triple play and multi-service integration, and realize the bearing of data, voice (VOIP) and video (VOD). It has a perfect address strategy, adopts a flexible mixed networking form of public network and private network, and can use hardware-based NAT method at the exit of campus network to solve the problem of insufficient IP address of school public network.

Feature 3: an easy-to-manage and easy-to-operate network.

Adopt ZTE's unified network management platform to implement perfect hierarchical decentralized management. Graphical Chinese operation interface is adopted, which is convenient to use. Support distributed network management and equipment topology management. Support real-time monitoring of network equipment, support sound and light, mail and SMS alarm. Support real-time performance statistics and report generation. Support cluster network management, automatic topology generation, batch configuration and batch update.
