Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
It should be noted that the SIP (Session initiation Protocol) Protocol is a multimedia communication Protocol established by IETF (Internet Engineering Task Force). The SIP protocol is an IP voice session control protocol originated from the Internet and has the characteristics of flexibility, easy realization, convenient expansion and the like.
Although the GB28181 protocol is extended over the SIP protocol, there are also major differences.
Typically, the SIP protocol is used for end-to-end voice and video telephony, and is therefore routed mostly subject to transactions or sessions (calls). And video monitoring equipment is generally accessed by adopting a protocol of national standard 28181.
Under the condition that the access scale of video monitoring equipment is increased in an explosive manner, the traditional single-point or active-standby signaling deployment method is difficult to meet the actual requirement. Moreover, the traditional signaling deployment system is usually constructed based on the SIP protocol, and is mainly designed for end-to-end network (VOIP) phones, which is difficult to meet the requirements of the national standard 28181 protocol.
In view of the above, the present invention provides a signaling transmission system. The signaling transmission system provided by the invention meets the requirement of the protocol of the national standard 28181, realizes the maximized improvement of access performance by separating the access service from the load balance and forwarding the affairs of the same equipment to the same application node, thereby better meeting the signaling deployment requirement among a large amount of video monitoring equipment.
Fig. 1 is a schematic structural diagram of a signaling deployment system provided in the present invention. The signaling deployment system provided by the present invention is described below with reference to fig. 1. As shown in fig. 1, the signaling deployment system includes: an access service module 101 and a load balancing module 102; the access service module 101 is communicatively connected to the load balancing module 102.
The access service module 101 is configured to forward, in a case that an application request message sent by a target device is received, the application request message to the load balancing module 102.
It should be noted that, in the case of receiving a SIP message, a conventional SIP proxy generally needs to parse the message header of the SIP message to obtain the next routing, and thus the load performance is reduced. The common four-layer load balancing is difficult to meet the transaction requirements of the signaling messages.
Therefore, the signaling deployment system provided by the invention separates the access service from the load balancing through the access service module 101 and the load balancing module 102, thereby improving the access performance to the maximum extent.
Specifically, the target device is an electronic device that has been successfully registered in the signaling deployment system. The signaling deployment system provided by the invention can deploy the signaling sent by the target equipment.
It should be noted that the target device in the embodiment of the present invention may be a video monitoring device, and may also be other electronic devices that need signaling deployment.
The target device may send an application request message to the access service module 101 in the signaling deployment system when there is a signaling deployment requirement.
After receiving the application request message sent by the target device, the access service module 101 may forward the application request message to the load balancing module 102 in the signaling deployment system.
Optionally, in the embodiment of the present invention, the number of the access service modules 101 is one or more.
Optionally, the application request message sent by the target device in the embodiment of the present invention may be an SIP message and an HTTP message of a UDP protocol or a TCP protocol, so that the integration and secondary development capabilities may be externally improved.
The UDP (User Datagram Protocol) is a connectionless transport layer Protocol in an OSI (Open System Interconnection) reference model, and can provide an information transfer service oriented to a transaction.
The TCP (Transmission Control Protocol) is a connection-oriented, reliable transport layer communication Protocol based on a byte stream.
The load balancing module 102 is configured to receive the application request message, and forward the application request message to the application service node 103 corresponding to the target device with the identity of the target device as a routing condition, so that the application service node 103 corresponding to the target device processes the application request message based on the protocol 28181 in the national standard.
Specifically, the load balancing module 102 may receive an application request message sent by the access service module 101.
After receiving the application request message, the load balancing module 102 may obtain an identity of a target device that sends the application request message by parsing a message header of the application request message.
After obtaining the identity of the target device, the load balancing module 102 may forward the application request message to the application service node 103 corresponding to the target device, using the identity of the target device as a routing condition, so that the transactions of the same target device can be completed in the same application service node 103, and the simplification of complex transaction logic can be realized.
After receiving the application service message forwarded by the load balancing module 102, the application service node 103 corresponding to the target device may process the application service message based on the protocol of national standard 28181.
It should be noted that the application service node 103 corresponding to the target device may be predetermined based on a priori knowledge and/or actual conditions; the application service node 103 corresponding to the target device may also be allocated by the signaling deployment system for the target device after the target device is registered in the signaling deployment system. In the embodiment of the present invention, the application service node 103 corresponding to the target device is not limited.
Optionally, the number of the load balancing modules 102 in the embodiment of the present invention may be one or more.
Based on the content of the foregoing embodiments, the access service module 101 is constructed based on four layers of load balancing.
It should be noted that, the four-layer load balancing generally uses an IP plus port method to perform route forwarding; the seven-layer load balance carries out proxy forwarding in a mode based on the request URL address. The four-layer load architecture is simple in design, specific message content does not need to be analyzed, network throughput and processing capacity are relatively high, and the seven-layer load balancing has the advantages of multiple functions and flexible and strong control.
Optionally, the access service module 101 in the embodiment of the present invention may be constructed based on four layers of load balancing, and may support packet access such as TCP, UDP, TLS, and the like, and provide multiple load policies based on IP (Internet Protocol ), such as polling, weighting, hash (hash function, also called hash), and source address.
Among them, TLS (Transport Layer Security) is a Security protocol, and aims to provide Security and data integrity guarantee for internet communication.
Based on the content of the foregoing embodiments, the load balancing module 102 is constructed based on seven layers of load balancing.
Optionally, the load balancing module 102 in the embodiment of the present invention may be constructed based on seven layers of load balancing, and may parse, process, and distribute the SIP message and the HTTP(s) message, and may perform processing such as routing, domain crossing, and real address.
The signaling transmission system comprises an access service module and a load balancing module which are in communication connection, wherein the access service module forwards an application request message sent by a target user to the load balancing module, the load balancing module takes the identity of target equipment as a routing condition and forwards the application request message to an application service node corresponding to the target equipment so that the application service node corresponding to the target equipment can process the application request message based on a national standard 28181 protocol, the access service and the load balancing can be separated, and the transaction of the same equipment is forwarded to the same application service node for processing, so that the access performance is maximally improved, the unlimited horizontal expansion between the signaling transmission system and the application service node can be realized, and the signaling deployment requirement between massive video monitoring equipment can be better met.
Based on the content of the foregoing embodiments, the access service module 101 is further configured to forward, in a case that a registration request message sent by any device is received, the registration request message to the load balancing module 102.
Specifically, any device in the embodiments of the present invention may be an electronic device that requests the signaling deployment system provided by the present invention to perform signaling deployment. Any one of the devices can be a video monitoring device and also can be other electronic devices.
In the case that any device that is not registered in the signaling deployment system has a signaling deployment requirement based on the signaling deployment system, the device may send a registration request message to a service access unit in the signaling deployment system.
After receiving the registration request message sent by the device, the access service unit may forward the registration request message to the load balancing module 102.
Optionally, the registration request message sent by any device in the embodiment of the present invention may be a SIP message and an HTTP message of a UDP protocol or a TCP protocol.
The load balancing module 102 is further configured to register any device in response to the registration request message, determine any device as a target device after the registration of any device is successful, and determine the application service node 103 corresponding to the target device based on the number of target devices corresponding to each currently available application service node 103.
Specifically, the load balancing module 102 may receive a registration request message sent by any device sent by the access service module 101.
After receiving the registration request message, the load balancing module 102 may register the device in response to the registration request message.
Optionally, the load balancing module 102 may return an authentication request message to the device in response to the registration request message. After receiving the authentication request message sent by the load balancing module 102, the device may return an authentication confirmation message corresponding to the authentication request message to the load balancing module 102. After receiving the authentication confirmation message, the load balancing module 102 may authenticate the device based on the authentication confirmation message, and may confirm that the device is successfully registered if the authentication is passed.
After the load balancing module 102 confirms that the device registration is successful, the load balancing module 102 may determine the device as a target device.
After the load balancing module 102 determines the device as a target device, based on the number of target devices corresponding to each currently available application service node 103, the currently available application service node 103 with the smallest number of corresponding target devices may be determined as the application service node 103 corresponding to the target device.
Optionally, the load balancing module 102 may further obtain the identity and/or the number of channels of the target device, and may perform condition judgment based on the identity and/or the channel data of the target device, so as to determine the application service node 103 corresponding to the target device based on a result of the condition judgment. For example: the application service node 103 corresponding to the target device having an association relationship with the target device may be determined based on the identity of the target device, so that the application service node 103 corresponding to the target device having an association relationship with the target device may be determined as the application service node 103 corresponding to the target device; alternatively, the application service node 103 corresponding to the target device with the same number of channels as the target device may be determined based on the number of channels of the target device, so that the application service node 103 corresponding to the target device with the same number of channels as the target device may be determined as the application service node 103 corresponding to the target device.
In the embodiment of the invention, after receiving a registration request message sent by any device, an access service module forwards the registration request message to a load balancing module, the load balancing module registers the device after receiving the registration request message, determines the device as a target device after the device is successfully registered, and determines an application service node corresponding to the target device based on the number of the target devices corresponding to each available application service node, so that the safety of a signaling deployment system can be improved.
Based on the content of the foregoing embodiments, the load balancing module 102 is further configured to update the corresponding relationship between the target device in the current period and the application service node 103 based on the reporting information received in the current period.
Specifically, after each application service node 103 is started, it will periodically send alive information to the load balancing module 102.
Based on the reporting information received in the current period, the load balancing module 102 may determine, among the application service nodes 103, a currently available application service node 103 and a currently unavailable application service node 103.
After the load balancing module 102 determines the currently available application service node 103 and the currently unavailable application service node 103, the corresponding relationship between the currently unavailable application service node 103 and the corresponding target device may be released, the target device corresponding to the currently unavailable application service node 103 is allocated to the currently available application service node 103, and the corresponding relationship between the target device and the currently available application service node 103 is established, so as to update the corresponding relationship between the target device and the application service node 103 in the current period.
Optionally, after the load balancing module 102 determines the currently available application service nodes 103 and the currently unavailable application service nodes 103, the corresponding relationship between the currently unavailable application service nodes 103 and the corresponding target devices may be released, and the target devices corresponding to the currently unavailable application service nodes 103 may be allocated to one or more currently available application service nodes 103 with the smallest number of corresponding target devices based on the number of target devices corresponding to each currently available application service node 103, so as to establish the corresponding relationship between the target devices and the one or more currently available application service nodes 103 with the smallest number of corresponding target devices.
The load balancing module in the embodiment of the invention is also used for updating the corresponding relation between the target equipment and the application service node in the current period based on the reporting information received in the current period, thereby further improving the availability and the deployment efficiency of the signaling deployment system.
Based on the content of the above embodiments, the number of the access service modules 101 is multiple, and/or the number of the load balancing modules 102 is multiple.

And a keepalived component is configured to realize high availability of the main and standby mode and provide unified virtual address access to the outside.
Where keepalived is a component similar to the layer3,4&5 exchange mechanism, i.e. we say layer3, layer 4 and layer 5 exchanges at all times. Keepalived may be used to detect the state of the server to ensure that the cluster is highly available.
