Problems solved by technology

This processing method requires that the egress router or firewall of the headquarters must support the ALG function. The ALG function is based on a specific application, such as SIP (Session Initiation Protocol, Session Initiation Protocol). If it is not a standard protocol, or the router does not support ALG at all, Then the solution will not be possible

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] The present invention provides a media stream centralized forwarding device, which is applied to a video management server in a monitoring system. The monitoring system includes a monitoring front-end device, a monitoring client device, a media stream server and a video management server. The media stream The server and the video management server are located in the same private network, and the egress router of the private network is connected to different operator networks. The following uses software implementation as an example for description, but the present invention does not exclude other implementations such as hardware or logic devices. Such as figure 2 As shown, the hardware environment in which the centralized media stream forwarding device operates includes CPU, memory, non-volatile memory and other hardware. The centralized media stream forwar...

Abstract

The present invention provides a method and device for centralized forwarding of media streams. The method includes: when a live request is received, query the monitoring client device access table, obtain the first access public network address, query the monitoring front-end device access table, Obtain the second access public network address; query the media stream forwarding table according to the first access public network address and the private network address of the media stream server, and obtain the first media stream public network address; The private network address of the stream server, query the media stream forwarding table, and obtain the public network address of the second media stream; send the public network address of the second media stream to the monitoring front-end equipment, notify the monitoring front-end equipment to initiate a media stream connection and send the media stream, and send the second media stream public network address A media stream public network address is sent to the monitoring client device, and the monitoring client device is notified to initiate a media stream connection and receive the media stream. The invention does not rely on the special function of the egress router, and realizes the centralized forwarding of the media flow between the two operators.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a method and device for centralized forwarding of media streams. Background technique [0002] With the development of the monitoring industry, the demand for WAN chain monitoring is increasing day by day, and each chain store is connected to the WAN from different operators. In order to reduce the network delay and packet loss caused by cross-operators, the outlet of the chain store headquarters needs to be connected to multiple operators at the same time, such as figure 1 As shown in the figure, the egress router of the headquarters connects the two networks of Carrier 1 and Carrier 2. In the centralized forwarding mode, the front-end NVR (Network Video Recorder, network hard disk recorder) needs to send the media stream to the MS (Media Server, media stream server), and the MS forwards it to the client. Such as figure 1 As shown, when XP1 broadcasts live to NVR1,...
