Education Industry

Introduction to the electronic information platform of Nan N

Date:2019-10-05 Clicks:
The construction of campus network serves the teaching application. The performance of the network will directly affect the operation of the application system. In the early days, the campus network only shared the main resources of the internal education system, shared simple databases, mostly based on two-tier exchange, and rarely had three-tier applications. There were problems in network security, and it did not have the ability of value-added management. At present, the construction of campus network should realize all-round data sharing, apply three-tier exchange and provide comprehensive service of quality assurance, so as to make the network more secure and reliable, so as to realize the automation of education management, multimedia teaching and library management, and also realize remote teaching through the Internet, providing value-added and manageable services.
 
 
 
technical requirement
 
 
The wireless network technology should be effectively utilized to maximize the port bandwidth, provide single-port bandwidth should be above 100M bit rate, and the ports of backbone equipment should have high-speed processing performance to provide congestion-free processing capacity.
 
 
 
It should have enough redundancy and fault-tolerant performance, including the redundancy of switching module, power supply, link and equipment, dynamic routing selection, network fault re-routing, and online hot swap and so on.
 
 
 
Adequate access capability and scalability should be provided, including the scalability of providing and accessing multiple access modes, the expansion of bandwidth and the smooth upgrade of speed, and the scalability of processing capability.
 
It should have the ability of quality of service (QoS) guarantee and bandwidth management to deal with packet delay, jitter, packet loss and throughput effectively.
 
It should have network multimedia applications, which can provide video conferencing, video interactive teaching, video on demand and other video network services to support multicast protocols.
 
VLAN should be partitioned and managed to improve the performance, security and manageability of the campus network.
 
It should have network management functions such as network equipment management and operation management.
 
 
 
 
 
Description of Access Scheme of Campus Network
 
 
 
 
 
Processing capacity: The switch is a L3 layer switch with advanced architecture. The backplane switching capacity reaches 133 bps, and the third layer switching speed reaches 6.6 Mpps. It can provide high-performance, multi-level solutions for enterprises, as well as strong support for service providers'transition to data networks.
 
 
 
 
 
The division of VLAN: The number of information points in campus network is huge. In the network, the virtual network can isolate broadcasting and ensure the network speed. At the same time, the virtual network can isolate workstations of different departments and further improve the security of the system. Huixinkang series switches support VLAN partitioning based on 802.1Q and tagged and untagged modes.
 
 
 
 
 
Broadcasting and multicast technology: In the network, with VOD server, you can anytime at any point in the campus network on-demand server teaching videos, songs, etc., to facilitate the learning of teachers and students, enrich their lives. The WWW server in the network is located behind the firewall. It locates data requests from the outside network accurately through address mapping, and shields other hosts from the inside network, thus providing reliable security. Using the network system composed of Huixinkang series switches to support multicast protocols IGMP and PIM can effectively improve the utilization rate of network bandwidth, and provide a strong technical guarantee for school video on demand, online teaching and other applications.
 
 
 
 
 
IP QOS: It supports the function of IP QOS. It can ensure the priority transmission of important data and time-sensitive data more effectively when combined with other switches of Huixinkang. Through port filtering, it can effectively control the unreasonable occupation of network bandwidth and provide an advanced network basic platform for distance teaching and multimedia teaching in schools.
 
 
 
 
 
Network management: Huixinkang's own network management software can monitor network traffic, display traffic distribution and other information, and alarm network anomalies. This function facilitates network management, eliminates the network management teachers in various campuses to and fro the pain, thus improving the efficiency of work.
 
 
 
 
 
Compatibility: The outstanding compatibility of network equipment makes the school keep updating network equipment, while protecting the investment in the original network. In addition, Huixinkang company adopts the unified technology and standards in the industry, and can work with other manufacturers'equipment to ensure that schools can use advanced hardware and software products at any time, thus further protecting the existing investment.
