Technical Field
The invention relates to a distributed access method of a video networking platform, and belongs to the technical field of cloud video access flow management.
Background
The GB28181 protocol is a unified equipment access and streaming media transmission protocol in security industry realized by the lead of the public security department, and specifies the interconnection structure, the basic requirements and the security requirements of transmission, exchange and control of a public security video monitoring networking system, and the technical requirements of control, transmission flow, protocol interfaces and the like. The security video monitoring industry gradually develops into a mature industry with huge market scale. The security video monitoring products continuously expand new application fields, and the security monitoring is not only applied to government and military but also applied to traffic, schools, hospitals and other fields at present. This also promotes the GB28181 protocol to be the primary basis for platform compatible front-ends and different brands of platform interconnections.
In the existing video networking platform, each streaming media server only receives media data of a plurality of front-end devices individually, so that an effective cluster cannot be formed. If a streaming media server is down, the front-end equipment connected with the streaming media server becomes a furnishing. In addition, the existing video networking platform cannot balance to the streaming media server node according to the video parameters of the front-end equipment, and the resource overhead before the streaming media server cannot be automatically balanced.

S2, after successful registration, the video networking platform inquires the resolution and the code stream of the video networking platform and stores the two attributes and the device id into a zookeeper;
S3, judging whether the streaming media is received or not: since the influence of IO is the code stream and resolution ratio at the maximum, it is inferred from the code stream whether the existing streaming media can process video:
S31, discarding if the stream media cluster can not receive the video, wherein discarding proves that the stream media cluster reaches the peak value of the processed video, the existing stream media is insufficient to support the video, and if the stream media node is extremely easy to downtime due to the fact that the stream media is still received, the stream media cluster is refused to receive the video;
S32: if the data can be received, load balancing is carried out, the streaming media nodes are distributed, and the streaming media processes the received data.

A basic flow diagram of a video networking platform is shown in fig. 1. Firstly, front-end equipment performs sip registration, after the registration is successful, a video networking platform inquires the resolution and the code stream of the front-end equipment and stores the two attributes and the equipment id into a zookeeper, and whether the existing streaming media can process the video or not is deduced according to the code stream because the code stream and the resolution are the largest in influence of IO, and if not, the streaming media are discarded. Discarding proves that the streaming media cluster has reached the peak value of the processed video, and if the streaming media cluster is still receiving, the streaming media node is extremely easy to downtime.
The invention discloses a distributed access method of a video networking platform, which is applied to a GB28181 national standard platform, wherein the GB28181 national standard platform comprises front-end equipment, a sip server and a streaming media server, and comprises the following steps:
s1, a real-time video stream enters front-end equipment and sip registration is carried out;
S2, after successful registration, the video networking platform inquires the resolution and the code stream of the video networking platform and stores the two attributes and the device id into a zookeeper;
S3, judging whether the streaming media is received or not: since the influence of IO is the code stream and resolution ratio at the maximum, it is inferred from the code stream whether the existing streaming media can process video:
S31, discarding if the stream media cluster can not receive the video, wherein discarding proves that the stream media cluster reaches the peak value of the processed video, the existing stream media is insufficient to support the video, and if the stream media node is extremely easy to downtime due to the fact that the stream media is still received, the stream media cluster is refused to receive the video;
S32: if the data can be received, load balancing is carried out, the streaming media nodes are distributed, and the streaming media processes the received data.
Preferably, in the step S1, the GB 28181-based national standard platform includes a front-end device, a sip server and a streaming media server, where:
The front-end equipment is used for monitoring the functions of video acquisition, coding, storage and transmission on site;
The Sip server provides registration, session connection establishment/termination functions and a module for session control;
and the streaming media server provides forwarding service of real-time media stream, storage of media, retrieval of historical media information and on-demand service.
Preferably, in step S2, the GB 28181-based national standard platform refers to a distributed architecture based on a GB28181 video networking platform, where: the zookeeper cluster is used for monitoring the change of the streaming media node and storing the related parameters of the front-end equipment by using a distributed coordination service.
Preferably, in step S2, zk is a zookeeper node, a plurality of zks form a zookeeper cluster, and a plurality of streaming media service nodes form a streaming media cluster.
Preferably, in the step S2, the zookeeper node directory is stored as { streaming media node } { device id }.
Preferably, in step S31, when the streaming media server is down and cannot recover to normal in a short time, the sip server will reinitiate registration to the redundant streaming media node according to the device id under the streaming media node stored on the zookeeper, thereby ensuring that the multipath video is not affected.
Preferably, in the step S32, because the server difference is small and the front-end devices are stored in the zookeeper, the number of front-end devices under each streaming media node is counted by adopting a load balancing policy of the minimum connection number LC.
Preferably, in step S32, the streaming media node with the smallest number of front-end devices is selected, and this node is the streaming media node for the next video access.
As shown in fig. 2, the technical scheme of the invention is to perform distributed processing based on a GB28181 video networking platform. Where zk is a zookeeper node, and multiple zks may form a zookeeper cluster. The plurality of streaming media service nodes form a streaming media cluster.
A redundant backup of streaming servers of a video networking platform is shown in fig. 3. When one streaming media server is down and cannot recover to normal in a short time (the zookeeper can automatically detect the heartbeat), the sip service can reinitiate registration to the redundant streaming media nodes according to the equipment id under the streaming media nodes stored on the zookeeper, so that the multipath video is ensured not to be affected. A specific zookeeper node directory may be stored as { streaming media node } { device id }.
Fig. 4 is a schematic diagram of streaming media load balancing of the video networking platform. Because the server differences are small and the head-end will be stored in the zookeeper (which will also delete the node if the head-end is disconnected). And the load balancing strategy of the minimum connection number LC is adopted to count the number of front-end devices under each streaming media node, and the streaming media node with the minimum number of front-end devices is selected. The node is the streaming media node of the next video access.
