What are the reasons for frequent channel drops in easycvr cascading easycvr?

EasyCVR As TSINGSEE The video fusion cloud service platform developed by Qingxi video , Not only support the national standard GB28181 agreement 、RTSP/Onvif、RTMP Standard agreement , And support HIKSDK、 Dahua SDK、 The sea, Ehome Such as the factory furniture has an agreement with SDK. The platform supports massive video convergence management , It can provide live video surveillance 、 Cloud video 、 Cloud storage 、 Video retrieval and review 、 Intelligent alarm 、 Platform cascading 、 Intelligent analysis and other video services . For example, through cascading functions ,EasyCVR The platform channel can be connected to the superior platform through the national standard protocol , Realize effective sharing and interworking of resources .

There's user feedback , subordinate EasyCVR The platform cascades to the upper level EasyCVR Platform time , The channel is frequently disconnected , But subordinates EasyCVR The platform is playing online normally , Ask us for assistance in troubleshooting . Today, let's share the troubleshooting process and solutions .

Our technical personnel pass the lower level EasyCVR The platform sees , Cascade channels are normally online , Only one channel of the superior platform is frequently disconnected , And it is regularly dropped , Basically, the number of dropped lines is within 10% , It went online again within five minutes .

I understand EasyCVR After the cascade message sending mechanism , We open the signaling log for troubleshooting .

So far, we suggest that the user configure the national standard cascade , Be sure to pay attention to SIP ID No conflict .

EasyCVR The platform is based on cloud edge end integrated management , Multi protocol support 、 Multiple types of video device access , Strong expandability 、 Flexible function , There are a large number of landing applications offline , Such as smart construction site 、 Smart campus 、 Smart factory 、 Smart community and so on .

Recently, we are working on EasyCVR Expand new functions , For example, video patrol 、H.265 transcoding H.264、 Electronic map and track tracking, etc , Welcome to pay attention to our update
