Abstract

The invention belongs to the technical field of the Internet and discloses a time sensitive network analysis system and method based on a redundancy mechanism. A redundancy module, a forwarding moduleand an analysis device form a whole analysis system. Through utilization of the redundancy module, input time sensitivity data is identified, copied and recovered; through utilization of the forwarding module, transmission is selected, thereby realizing redundancy of audio / video business streams; and through addition of the analysis device, a high efficient analysis method is provided for a failure node and link existing in a network. The failure node or link in the network can be effectively identified, the harm brought to the network by the failure link can be avoided, a reliable transmission mode is provided for a future streaming media audio / video network, and the network reliability and transmission service quality of a time sensitive network are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a time-sensitive network analysis system and method based on a redundancy mechanism. Background technique [0002] With the rapid development of IT technology, the rapid development of time-critical applications, such as audio-visual broadcasting (AVB), automotive industry, industrial automation and the so-called Internet of Things, requires highly reliable real-time Ethernet standards to support these technologies. Enables Ethernet to meet the deterministic requirements of emerging applications. In 2005, the IEEE 802.1 task group formulated AVB, Ethernet Audio Video Bridging (Ethernet Audio Video Bridging), which is a set of real-time The protocol set for audio and video transmission effectively solves the problems of timing, low delay and traffic shaping of data transmission in Ethernet. In 2012, the IEEE 802.1 task group changed the name of AVB to TSN—Time Se...
