What is the reason for the abnormal flow consumption of 4G devices accessing the easygbs platform?

TSINGSEE The platform of Qingxi video can support multiple network types of access , Include 4G、WiFi、 Wired, etc , The platform can be used in complex network environment , Such as intranet 、 Private network 、 Public network 、 LAN, etc , Collect the audio and video information of the front-end equipment 、 transmission 、 Processing and distribution , Realize full terminal 、 Full platform coverage .

among ,EasyGBS It is based on the national standard GB28181 Protocol video platform , In terms of video capability , It can realize live video real-time monitoring 、 videotape 、 Retrieval and review 、 Voice talk 、 Cloud storage 、 The alarm 、 Platform cascade, etc , There have been a large number of landing applications in video surveillance and other scenes .

There's user feedback ,4G After the device is connected to the platform , The traffic has reached 20G, Lead to 4G The device network card is down . According to the feedback of users , We immediately checked .

First, we will replace its equipment with wired access platform , The test observed for three days and found no abnormal flow . Check in the flow monitoring in the platform channel , The usage of flow is normal . In order to reproduce the problem , So for 4G The device has been restored to the Internet , You can see it in the picture below ,4G The device is online and on demand , But there is always a playback state .

By calling API Interface view , Find out 4G The equipment has been pulled , As a result, the flow consumption of the equipment always exists . So I repeatedly confirm with the user whether anyone is watching the video and streaming , The user replied that no one logged on to the platform . In order to further investigate what causes the equipment to be pulled all the time , We then checked the service packet capturing .

Check the data package to see , Someone called the interface of this device and it has been playing , Therefore, the flow rate continues to increase . Finally, communicate with the user again and get confirmation ： Because the interface was called during the demonstration , But it's not closed , This leads to abnormal consumption of traffic .

After closing the interface call , The user's device traffic consumption returns to normal .

EasyGBS The platform can provide streaming media access 、 Handle 、 Forwarding and other services , Support Intranet 、 The monitoring equipment of the public network passes the national standard GB/T28181 Protocol for live video surveillance . The platform has realized a very rich security video function , There are also a large number of landing applications offline , Such as bright kitchen and bright stove 、 Snow project 、 Ping An Village, etc
