Embodiment Construction

[0023] The applicant of the present application proposed a tunnel technology in a previous related patent application to solve the background technical problems. However, there are still some areas that need to be optimized in the tunnel mode. The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Please refer to figure 1 , before introducing the present invention, the basic technology of tunnel realization is firstly introduced, in which a single-domain IP monitoring system is shown. Single-domain IP monitoring system means that there is only one monitoring management domain in the system. Such a system may have many branch networks, but only one branch undertakes management tasks. Typically, only one video management server (VM) controls the monitoring system , the branch in charge of management is usually called the central network, in addition to VM, it can also include monitoring se...

Abstract

The invention provides a method for saving bandwidth, which is applied to a monitoring node in an IP monitoring network, wherein the IP monitoring network comprises a plurality of IP monitoring nodes, a management server and a tunnel server, and the method comprises the steps of acquiring and saving an exclusive authentication identifier allocated to a local node and an opposite-terminal monitoring node by the management server before performing the data service communication with the opposite-terminal monitoring node; transmitting a detection message to the opposite-terminal monitoring node under a non-tunnel mode, wherein the detection message carries the exclusive authentication identifier; and transmitting a data message to the opposite-terminal monitoring node through the non-tunnel mode when an opposite-terminal detection response message is received. Due to the adoption of the method and the device, the problems such as the consumption of bandwidth of a wide area network under the tunnel mode can be effectively solved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a method and device for saving bandwidth in an IP monitoring system. Background technique [0002] IP network-based video surveillance has gradually developed into a mainstream solution in the industry, and has been successfully applied to large-scale projects such as safety projects, expressways, public security networks, and parks. The standardization and openness of IP also make it easy to integrate various network islands and make it easy to expand the network scale. Considering the shortage of IPv4 address resources and the reality that the existing regional network address segments overlap with each other, as well as the needs of various network security, isolation devices such as NAT, firewalls, and security isolation gatekeepers are widely used in large-scale networks. This makes the signaling and business processes of the IP-based video surveillance system very complicat...
