Problems solved by technology

[0007] However, the client and server send and receive messages as much as possible, without any guarantee for real-time and reliability
When the network is congested, the data packets will be delayed or discarded, which will affect the transmission of important signaling and the real-time transmission of streaming media, and affect the stability of the system
[0008] In addition, in the Onvif devices of different manufacturers, because the protocol does not include QoS by default, it is impossible to set it uniformly on the device side, and it is necessary to log in to the web interface of each device that supports functions to configure

Abstract

The invention discloses a method for realizing QoS network optimization based on the Onvif protocol. By extending the design of the network interface of the Onvif protocol and designing a QoS implementation scheme in the operating program of an embedded device based on Linux, the Onvif protocol can be passed between devices. Dynamically set QoS network parameters so that when the network is overloaded and congested, important services will not be delayed or lost, and the real-time and stability of data transmission can be optimized. The invention is applied to a multi-channel concurrent video monitoring system with high real-time requirements, and enables QoS network optimization between devices of different manufacturers through the Onvif protocol, so as to solve the problem of data transmission delay and jam in the monitoring system.

Description

technical field [0001] The invention belongs to the technical field of network transmission interaction and video monitoring, and relates to a method and application for Onvif protocol extension design and embedded program QoS design and realization. Background technique [0002] Onvif protocol is an open network video interface standard, which is used in the field of security monitoring and provides a standardized network protocol. Onvif standardizes the format type and interaction mode of network data, builds a network communication model, provides a common interface for communication between devices, and enables devices of different manufacturers with different functions to realize interconnection and interoperability. [0003] QoS service quality is achieved through network technology solutions, providing better service capabilities for specified communications in the network, and optimizing the delay and congestion of specified communication networks. In the video surve...
