Abstract
The invention discloses a method for realizing QoS network optimization based on an Onvif protocol, which realizes the dynamic setting of QoS network parameters between devices through the Onvif protocol by carrying out extension design on an Onvif protocol network interface and designing a QoS realization scheme in an embedded device operation program based on Linux, so as to achieve the purposes that important services are not delayed or lost when the network is overloaded and congested, and the real-time performance and the stability of data transmission are optimized. The invention is applied to a multi-channel concurrent video monitoring system with high real-time requirement, and enables the QoS network optimization among different manufacturer devices through the Onvif protocol, thereby solving the problem of data transmission delay blockage in the monitoring system.
Description
Technical Field
The invention belongs to the technical field of network transmission interaction and video monitoring, and relates to a method for realizing Onvif protocol extension design and embedded program QoS design and application.
Background
The Onvif protocol is an open network video interface standard, is applied to the field of security monitoring, and provides a standardized network protocol. The Onvif standardizes the format type and the interaction mode of network data, builds a model of network communication, provides a universal interface for communication among equipment, and realizes interconnection and intercommunication among equipment with different functions of different manufacturers.
The QoS service quality is realized by a network technical scheme, provides better service capability for specified communication in a network, optimizes the delay and blockage problems of the specified communication network, and is very necessary for key signaling and high-real-time streaming media in a video monitoring system. When the network is overloaded and congested, the specified service is ensured not to be delayed and discarded, and the transmission real-time performance and stability are ensured.
DSCP, i.e. differentiated services code point, is a classification standard of Diff-Serv differentiated services model in QoS technical scheme. In the service class TOS flag byte of each packet IP header, priority is given by an encoded value.
The embedded IPC and NVR are hardware platforms based on Haisi chips and ARM Cortex kernels, the embedded IPC and NVR run in an embedded Linux system environment, the IPC realizes audio and video acquisition, coding and transmission, and the NVR realizes streaming media receiving and storage. And the IPC and the NVR carry out signaling interaction and transmission of streaming media data through an Onvif protocol.
In the existing technical scheme, the Onvif protocol defaults without QoS acquisition and setting, and IPC and NVR equipment do not support the QoS function scheme. The mode of transmission of data in a video surveillance system is therefore to send and receive messages as much as possible.
However, the client and the server send and receive messages as much as possible, and no guarantee is provided for instantaneity and reliability. When the network is congested, the data packet is delayed or discarded, which affects important signaling transmission and streaming media real-time transmission, and affects system stability.
In addition, in the Onvif devices of different manufacturers, because the default protocol does not include QoS, the setting cannot be uniformly performed on the device side, and a device Web interface of each support function needs to be logged in for configuration.
In view of the above, these problems and disadvantages are the problems that the art is presently compelling to address.
