In recent years, with the rapid development of the economy, the requirements for informationization in various industries have been continuously improved. Streaming media technology has been widely used in various industries, such as video training assessment, live conferences, remote video conferences, video news information release, and publicity. Education, resource sharing and unified management have become trends.
Streaming media system plays an important role in the informationization of various industries, which not only promotes the application and development of Internet technology, but also meets all aspects of informationization.
Unable to realize unified management and application of video resource distribution - new challenges of streaming media system
After the establishment of the streaming media system, there is often a flexible management mechanism that can be managed and managed in the sub-node and the central node. Even if there is a single management mode, each sub-node has no independence. This can lead to inefficiency of the entire streaming media platform and its inability to function efficiently.
VIEWGOOD (Age) has developed the WebCDN streaming multi-node integrated management application platform solution based on years of research and development and service experience in the streaming media industry.
Program advantage
The resource storage is localized, and each node can independently manage its own resources, which reduces the work pressure of the central unit.
More efficient load balancing ensures that local users use resources nearby.
Reduced network bandwidth and server pressure on the central site.
Maximize sharing of video resource information and reduce information silos.
The following is an example of an education industry solution.
The program is centered on an education bureau. The following schools are subordinate nodes' subordinate management mode. The center is responsible for resource integration and unified scheduling. Each sub-node accepts unified management of the center, and each sub-node is relatively independent. Software platform, for each school's subordinate units, the school node is a complete and independent streaming media platform. This unified management and relatively independent application model greatly improves the work efficiency, and is more suitable for the education industry structure, so that the resources between the education superiors and the level units can be effectively distributed, shared, communicated and exchanged.
As shown below:

On the basis of this network structure, effective management and application are formed between the Education Bureau and the schools under its jurisdiction. The management functions belong to the Education Bureau Center. The application nodes and centers operate independently. The live video and on-demand resources are managed through this management method. Perform an orderly flow. As shown in Figure 2 below:

VIEWGOODWEBCDN Streaming Media Multi-Node Integrated Management Application Platform Education industry solutions are mainly divided into central management functions and platform functions of each node. The central management functions are mainly video distribution management, video live collection, reward point management, and resources between the coordination center and nodes. Interaction management, node management, etc., the central management functions are as follows:
WEBCDN video resource distribution unified management
WEBCDN node live channel unified scheduling management
WEBCDN live channel sharing unified scheduling management
Point reward (charge) management
Node authority management
The central platform and each sub-node platform can be used as a complete set of platforms. In addition to the node management functions unique to the central node, each platform has functions such as management and application, and directly serves the application of the education industry. Features:
Management functions such as authentication, statistics, and permissions
Resource uploading, classification, management, and query functions
Video on demand, live broadcast, recording and other functions
Platform security protection
Core technology improves performance (VConnect, KeyBuffey, NoDelay, NoGap, hP2P)
Design
VIEWGOODWEBCDN Streaming Media Multi-node Integrated Management Application Platform is a multi-node streaming media management application software. The center and nodes are effectively managed and applied through the WEBCDN module. Each node is also a set based on WAN/Metropolitan Area Network. Streaming media service system, the system adopts MPEG-4 codec technology, and supports MPEG-1 (mpg, dat, mp3), MPEG-4 (avi, asf, wmv), REAL and many other mainstream media formats to provide network TV services. Various live streaming services such as live broadcast services, TV recording services, live recording services, desktop video interactive services, video on demand services, and file broadcast services. Support complete remote WEB management to achieve unattended operation. ,
The program features simple and convenient operation
The whole set of streaming media platform is easy to install and implement, easy to operate and manage, and easy to use without special training.
Safe and stable operation
Access authentication, service authentication, controllable multicast, controllable unicast, network optimization, content anti-theft (anti-download) control are combined to ensure the security of the whole process of the business, system rights management ensures background security, and the platform runs safely. .
Mature technology
This set of streaming media platform solution is designed by VIEWGOOD for years of streaming media development and education industry service experience, in order to systematically meet the requirements of education in streaming media applications. The system adopts the traffic distribution technology of the video distribution network, the flow service admission control, the multi-layer distribution system, the differentiated service mode of the IP network, and the video stream VConnect, KeyBuffer, and NoDelay technologies, so that the end-to-end service quality of the streaming media service is guaranteed.
Function expands economical and on demand
The seamless connection between the node platform and the central platform is convenient, and the node expansion or the expansion within the node can be performed at any time according to requirements without cutting.
Strong network scalability
The system can rely on the existing broadband network platform to superimpose the service network; the video network and the OSS can be deployed flexibly to meet the staged requirements of the business development; similarly, the OSS can also be extended to the hierarchical network system. The system provides the "acquisition, recording, and release separation" service transmission scheme of the video stream and the "acquisition, recording, and distribution convergence" service transmission scheme, which is suitable for the smooth upgrade of the streaming media service at various stages of network development, and rational utilization of existing network resources.
The Strain Clamp is primarily used to fix the conductor, ground wire terminals on tension towers of overhead lines, distribution lines and distribution equipments in substations, power plants. It also can fix the guy wire terminals on poles. Moreover, it bears all the tension of conductors, ground wires and lightning conductors. According to its configuration and installation means, the strain clamp can be divided into compression type, bolt type and wedge type. Generally, the compression type includes hydraulic compression type and explosive compression type. Generally, malleable cast iron, steel, and aluminum alloy are used as its materials.
All the ferrous metal should be hot-dip galvanized.
