How can cluster deployment solve the needs of massive video access and large concurrency?

With the Internet of things 、 Internet 、 big data 、 The development of video technology , The application of video surveillance platform is also gradually expanding . We are also exposed to various types of projects in many actual scenarios , Many projects have the following needs and problems to be solved ：

1） Multi project platform , Management is difficult

The project currently uses multiple video platforms , There are multiple databases , Video cannot be aggregated and managed , Data not interworking , Cannot call resources to each other , Unified project management is difficult .

2） Massive device access , Insufficient platform concurrency

The project currently has a large number of equipment access （ Tens of thousands of roads ）, High concurrency leads to high database pressure , The platform is overloaded , It is easy to cause delay or error , Affect project management .

3） No prompt when the device is offline

There is no timely message notification and reason prompt when the device is offline , Make the management personnel unable to 、 Quickly understand and troubleshoot equipment faults , Affect the normal operation and maintenance of the project .

For the needs of massive access and concurrency in the project , We have the following two solutions ：

1、EasyGBS+EasyNVS Architecture ：

1） advantage ：

• EasyGBS Support national standard access
• Real time streaming media processing , Standard stream output
• Equipment management and monitoring
• Voice broadcasting and intercom functions

2） To be improved ：

• EasyGBS No video convergence capability , Access required EasyNVS Achieve unified management
• EasyNVS The platform does not have equipment offline message prompt and preliminary cause analysis , Unable to provide the administrator with timely judgment of the offline situation of the device

2、EasyCVR Cluster solution

1） advantage ：

• With cluster function , Multiple nodes can call each other in a database
• With video transcoding function , Can be H.265 Transcode as H.264
• Have the offline record of national standard equipment , The platform can analyze and judge the reason why the equipment is offline
• Self adaptive video convergence function , The platform can view all connected videos , And can support H.265 Play
• Have EasyGBS All the video capabilities of the platform

2） Continuous development ：

• AI The analysis function will be more concretely displayed
• The electronic map will later be changed into a three-dimensional map

Compare with EasyGBS+EasyNVS Architecture ,EasyCVR The server cluster solution of is more suitable for the access and management of massive devices and the needs of large concurrency . As an efficient way of server collaboration , The cluster capability realizes the load balancing of the server , It meets the high concurrency requirements of users , At the same time, it provides high reliability 、 Strong extension 、 Scalable service features , Realize the sharing and free calling of databases in multiple servers .

EasyCVR The following capabilities of can perfectly solve the problem of large access 、 Problems in large concurrency scenarios ：

1） Video convergence capability

Be able to separate devices 、 Unified access and centralized management of video resources such as platforms , Maximize the application of video monitoring resources .EasyCVR Compatible with almost all webcams on the market 、NVR、 Encoder and other video source equipment , Support multi protocol access , Support RTSP/RTMP/FLV/HLS/WebRTC Video stream output in other formats , Can be realized in PC、 mobile phone 、 Flat 、 Watch videos on multiple terminals and devices such as wechat .

2） Device offline prompt

Support centralized management and unified control of access devices , It can monitor the status of equipment in real time , Including that the device is offline , And can prompt the device offline , So that users can view and deal with it in time .

3） Cluster capabilities

Clusters can solve the need for large concurrency by sharing server pressure , Ensure the smoothness of the platform 、 Stable operation , It can not only improve the flexibility and expansibility of the platform's video service capability , It can also improve the computing and processing capacity of the server .

4） Kernel monitoring alarm

EasyCVR The kernel of can listen to every concurrency of this node , And show it in the interface . If it exceeds the scheduled number of concurrent , The alarm function of concurrent overrun will be automatically triggered .

5） Video transcoding capability

EasyCVR Video transcoding capability can realize video streaming code playback without changing camera settings . If the video encoding format of the camera is H.265, The transcoding function can be used to convert to H.264, And play it on the page . Transcoding provides users with a variety of options , More flexible video capabilities , More expandable .

EasyCVR Platform deployment is simple 、 High compatibility , The platform adopts distributed deployment , It can provide unified API Interface , Connect devices 、 Connect data 、 Connect applications , Facilitate the rapid integration of third-party platforms . The platform is based on cloud edge end integrated management , It can support real-time video monitoring 、 Cloud video 、 Cloud storage 、 Playback and retrieval 、 Intelligent alarm 、 Platform cascade and other functions .

Recently, we are working on EasyCVR Expand new functions of the platform , For example, server clusters 、 Electronic map and track tracking 、 Video rounds 、 Video transcoding and so on , Interested users can go to the demonstration platform for experience or deployment testing .
