detailed description

In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

In the description of the invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection , or integrally connected; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

It should be noted that the SIP (Session initialization Protocol, session initialization) protocol is a multimedia communication protocol formulated by the IETF (Internet Engineering Task Force, Internet Engineering Task Force). The SIP protocol is an IP voice session control protocol originating from the Internet. It is flexible, easy to implement, and easy to expand.

Although the GB28181 protocol is extended from the SIP protocol, there are also big differences.

Usually, the SIP protocol is used for end-to-end voice and video telephony, so routing is usually performed on the basis of transactions or sessions (calls). Video surveillance equipment is usually accessed using the national standard 28181 protocol.

When the access scale of video surveillance equipment is growing explosively, the traditional single-point or active-standby signaling deployment methods have been difficult to meet actual needs. Moreover, the traditional signaling deployment system is usually based on the SIP protocol, which is mainly designed for end-to-end network (VOIP) telephony, and it is difficult to meet the requirements of the national standard 28181 protocol.

For this, the present invention provides a signaling transmission system. The signaling transmission system provided by the present invention meets the requirements of the national standard 28181 protocol. By separating the access service from load balancing and forwarding the transactions of the same device to the same application node, the access performance can be improved to the maximum extent, thereby better Meet the signaling deployment requirements between massive video surveillance devices.

However, the general four-layer load balancing is difficult to meet the transaction requirements of signaling messages.

Therefore, the signaling deployment system provided by the present invention separates the access service from the load balance through the access service module 101 and the load balancing module 102, thereby maximizing the improvement of access performance.
