Problems solved by technology

But the disadvantage of this method is that the data bandwidth is increased by two times or even N times (N>2, if multi-link active / standby is considered), which will greatly increase the capacity and load of the switching equipment, thereby increasing the overall cost of the system

Embodiment 1

[0040] like figure 1 As shown, a distributed system for fast link active / standby switchover based on load sharing includes distributed sending end nodes, distributed receiving end nodes, network switching devices, and service management nodes. Among them, the distributed sender node, the distributed receiver node, the service management node and the network switching device are connected through a standard network link interface. The service management node is configured and managed for each distributed sender node and receiver node according to the link active / standby mode required by the user. The service management node is connected to the network switching device through the network interface; the network switching device is A link connects each distributed sending end node and receiving end node to realize the link routing exchange between each node; the distributed sending end node is connected to the network switching device through multiple links, and the distributed r...

Abstract

The invention belongs to the technical field of image communication, and particularly relates to a fast link main/standby switching distributed system and method based on load sharing. The system comprises a distributed sending end node, a distributed receiving end node, network switching equipment and a service management node. In the system, each sending end node and each receiving end node can realize multi-link backup; the service data of each node is subjected to load sharing among multiple working links, so that the system flow multiplication cannot be caused, and the system cost and the stability cannot be influenced; and meanwhile, when the link on the node fails, the data layer of the node automatically realizes the balance of the service data on each available link without participation of the service layer, so that the rapid and seamless service data switching requirement is met, and the influence of audio and video service link switching on the sense of people is reduced.

Description

technical field [0001] The invention belongs to the technical field of image communication, and specifically relates to a distributed system and method for fast link active-standby switchover based on load sharing. Background technique [0002] In the field of communication, in order to ensure the reliable transmission of the link, the key node equipment in the system is often required to support the active and standby links. When the main link fails, the standby link can maintain normal operation to ensure the normal operation of the system. Link active and standby technology is also widely used in image communication systems, especially in distributed audio and video systems. Since audio and video data can be directly perceived by human senses, it is required that the link be switched as fast and seamless as possible to minimize the impact on human senses. [0003] At present, the processing method of active and backup links in the distributed audio and video system is to...
