Problems solved by technology

[0005] The purpose of the present invention is to provide a backup switching method and system for a universal network passport server, to solve the problem that the UNP server in the prior art is only fixedly deployed in the upper-level domain, and the UNP server has no backup switching mechanism, which causes the UNP server to be overloaded. When the UNP server fails, the entire video surveillance network cannot work normally due to the single point of failure of the UNP server

Embodiment Construction

[0042] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0043]A kind of backup switching method of universal network passport server in this embodiment, such as figure 1 shown, including:

[0044] Step S1, the universal network passport client of the intermediate domain node and the lower domain node initiates the establishment of the universal network passport server to the universal network passport server of the upper domain node.

[0045] This embodiment takes a typical universal network passport UNP networking solution in the video surveillance system as an example for illustration, and its networking schematic diagram is as follows figure 2 As shown, the entire video surveillance system is divided into three levels according to different management rights, which are upper-level d...

Abstract

The invention discloses a backup switching method and system of a universal network passport server. The method comprises the following steps: a universal network passport client sends universal network passport information of a current device to the universal network passport server through an established universal network passport connection, the universal network passport server generates a universal network passport information list according to the universal network passport client and the universal network passport information of a current node and sends the universal network passport information list to the universal network passport client of the server, and the universal network passport client selects a standby universal network passport server according to the received universal network passport information list and a preset rule, and switches to the standby universal network passport server in the case of a fault of the universal network passport server so as to establish a new universal network passport connection. The problem that in the case of the fault of the UNP server, the entire video monitoring network cannot normally work due to the fault of the UNP server in the prior art is solved.

Description

technical field [0001] The invention belongs to the field of video monitoring, and in particular relates to a backup switching method and system for a universal network passport server. Background technique [0002] With the development of video surveillance technology and IP network, video surveillance based on IP network has gradually developed into a mainstream solution in the security industry, and has been successfully applied to large-scale projects such as safety engineering, intelligent transportation, and park management. The standardization and openness of IP also make it easier to integrate various network islands and make it easier to expand the network scale. Due to the shortage of IPv4 address resources and the needs of various network security, NAT devices, firewalls, security isolation gatekeepers and other devices are widely used in IP networks, which makes the signaling and business processes of IP-based video surveillance systems become It is very complic...
