Embodiment Construction

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] figure 1 A single-domain IP surveillance system is shown. A single-domain IP surveillance system refers to only one surveillance 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 surveillance system. , This branch responsible for management is usually called the central network. In addition to VM, it can also include monitoring servers such as data management server DM, MS and data centralized storage device IPSAN.

[0034] figure 1 The monitoring system includes isolation equipment, EC, VC, VM, DM, MS and LNS server. In the monitoring system of the present invention, EC, VC and various servers are called monitoring nodes. exist figure 1 , the branch network EC and VC are located on the i...

Abstract

The invention provides a wide area network bandwidth saving method in an IP monitoring system. The monitoring system comprises EC, VC and LNS, wherein at least one EC and VC establish an L2TP tunnel connection with LNS. The method comprises the steps of receiving a registration message sent by EC and VC, saving EC and VC address information in the registration message, establishing a monitoring video stream transmission channel between EC and VC and through L2TP tunnel, sending an instruction to attempt to carry out intranet communication with an opposite end to EC and VC; receiving an intranet communication attempt report sent by VC, determining whether EC and VC can carry out communication with the intranet according to the address information of the report message and the self-saved address information, and if EC and VC can carry out communication with the intranet, sending a communication mode switching instruction to instruct EC to switch from an L2TP tunnel communication mode toan intranet communication mode. The method and the device provided by the invention effectively solve the problem of wide area network bandwidth consumption inthe tunnel mode.

Description

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