By accessing a plurality of external domains such as a plurality of upper domains or lower domains, a large amount of resources can be accessed into the video monitoring service signaling processing system, so that ten-million-level resource networking is achieved, wherein each external domain has a part of resources, and a signaling gateway of a first-level domain processes all video monitoring service signaling sent by the upper domains or the lower domains.

Detailed Description

In order to make the technical solutions and advantages of the present application more clear, the following describes the embodiments of the present application in further detail.

The embodiment of the application provides a video monitoring service signaling processing system, which can be used for processing ten-million-level video monitoring service signaling and can also be used for processing non-ten-million-level video monitoring service signaling. The ten-million-level video monitoring service signaling is triggered by a ten-million-level video resource networking video monitoring service signaling processing system, and the ten-million-level video resource networking video monitoring service signaling processing system can trigger the ten-million-level video monitoring service signaling and can also trigger non-ten-million-level video monitoring service signaling. In addition, in the worst case of the video monitoring service signaling processing system with ten-million-level video resource networking, ten-million-level video monitoring service signaling is triggered, and may not be generated. Wherein, one video monitoring service signaling comprises the sum of all interactive video monitoring service signaling triggered by one video monitoring service.

Referring to fig. 1, the video surveillance service signaling processing system includes a plurality of video surveillance service signaling processing subsystems, each video surveillance service signaling processing subsystem is used as a domain, it is assumed that the current video surveillance service signaling processing subsystem is used as a first-level domain 11, and other video surveillance service signaling processing subsystems may be used as a higher-level domain or a lower-level domain of the first-level domain 11. The first-level domain 11 may have a plurality of upper-level domains or a plurality of lower-level domains. For example, the first-level domain 11 has N upper-level domains and M lower-level domains. Wherein M, N are all positive integers.

For convenience of description, an upper domain of the first-level domain 11 is referred to as a second-level domain 12, and a lower domain of the first-level domain 11 is referred to as a third-level domain 13; alternatively, an upper domain of the first-level domain 11 is referred to as a third-level domain 13, and a lower domain of the first-level domain 11 is referred to as a second-level domain 12. Data transmission is performed between the first-level domain 11 and the second-level domain 12 through a network, and data transmission is also performed between the first-level domain 11 and the third-level domain 13 through a network. In addition, data transmission is performed between the first-level domain 11 and the second-level domain 12, and between the first-level domain 11 and the third-level domain 13, by SIP (Session Initiation Protocol) communication. The data transmitted between the first-level domain 11 and the second-level domain 12 may be a video monitoring service signaling, and similarly, the data transmitted between the first-level domain 11 and the third-level domain 13 may also be a video monitoring service signaling, and the video monitoring service signaling may be an SIP signaling.

The first-level domain 11 includes a first proxy server 111 and a signaling gateway cluster 112, and each signaling gateway cluster 112 includes a plurality of signaling gateways 1121. In this embodiment, taking the example of transmitting the first video monitoring service signaling between the first level domain 11 and the second level domain 12 as an example for description, the first proxy server 111 is configured to receive the first video monitoring service signaling of the second level domain 12, select the target signaling gateway 1121 from the signaling gateway cluster 112, and process the first video monitoring service signaling through the target signaling gateway 1121 to obtain the second video monitoring service signaling.

It should be noted that, when the scale of the video monitoring service signaling is large and reaches the million-level scale, the million-level scale video monitoring service signaling may be distributed to a plurality of target signaling gateways 1121 in the signaling gateway cluster 112, and the plurality of target signaling gateways 1121 process highly concurrent million-level scale video monitoring service signaling, so as to improve the processing speed and efficiency of the million-level scale video monitoring service signaling, thereby efficiently processing the million-level video monitoring service signaling in real time.

In one possible implementation, the first level domain 11 also includes a networked management server 113. The networking management server 113 is configured to determine a gateway identifier of the target signaling gateway 1121, and send the gateway identifier to the first proxy server 111.

In another possible implementation, the first level domain 11 also includes a second proxy server 114. The second proxy server 114 is configured to receive the second video surveillance service signaling sent by the target signaling gateway 1121, and send the second video surveillance service signaling to the third-level domain 13.

In another possible implementation, the first level domain 11 further includes a database server 115; accordingly, before the second proxy server 114 sends the second video surveillance service signaling to the third-level domain 13, the second proxy server 114 sends a verification instruction to the database server 115, where the verification instruction is used to verify whether the port identifier of the third-level domain 13 exists in the database server 115. When the port identification of third tier domain 13 is stored in the database server 115, an acknowledgement message is sent to second proxy server 114. The second proxy server 114, upon receiving the acknowledgement message, sends a second video surveillance service signaling to the tertiary domain 13. Wherein the database server 115 stores therein the port identification of the authenticated domain.

The architecture of the second-level domain 12 and the architecture of the third-level domain 13 are the same as those of the first-level domain 11, that is, the second-level domain 12 and the third-level domain 13 each include a first proxy server 111, a signaling gateway cluster 112, a networking management server 113, a second proxy server 114, and a database server 115. Moreover, each domain comprises a first proxy server 111, a signaling gateway cluster 112, a second proxy server 114, a networking management server 113 and a database server 115, and by adopting the distributed deployment, the concurrency condition of tens of millions of video monitoring service signaling can be borne, and the processing speed and efficiency of the video monitoring service signaling are improved.

It should be noted that, when the third-level domain 13 is a lower domain of the first-level domain 11, and the third-level domain 13 is the last domain in the video surveillance service signaling processing system, the second proxy server 114 may not be included in the third-level domain 13. After the target signaling gateway 1121 of the third-level domain 13 processes the video monitoring service signaling, the target signaling of the third-level domain 13 sends the video monitoring service corresponding to the video monitoring service signaling to the upper-level domain of the third-level domain 13.

Another point to be noted is that the first-level domain 11, and its upper-level domain and lower-level domain may be mutually converted. For example, when the original upper domain is used as the current first-level domain 11, the original first-level domain 11 is a lower domain of the current first-level domain 11; when the original lower domain is the current first-level domain 11, the original first-level domain 11 is the upper domain of the current first-level domain 11. The video monitoring service signaling can be transmitted from a superior domain to a subordinate domain through a first-level domain 11, and can also be transmitted from the subordinate domain to the superior domain through the first-level domain 11; that is, the first-level domain 11 may receive the video monitoring service signaling from the upper-level domain, and may also receive the video monitoring service signaling from the lower-level domain.

The video monitoring service signaling may be video monitoring services such as retrieving monitoring videos, registering and heartbeat, resource subscription and pushing, historical/real-time video and audio on demand, video and audio file retrieval and downloading, and alarm event notification, and in the embodiment of the present application, the type of the video monitoring service signaling is not specifically limited.

The first level domain includes: the system comprises a first proxy server and a signaling gateway cluster, wherein the signaling gateway cluster comprises a plurality of signaling gateways; in the embodiment of the present application, a second domain sends a first video monitoring service signaling to a first domain, and the first domain sends a second video monitoring service signaling to a third domain, for example, the method includes:

step 201: the first proxy server receives a first video monitoring service signaling of a second-level domain in the video monitoring service signaling processing system.

The first video monitoring service signaling is triggered by the second-level domain, or the superior domain of the second-level domain is sent to the first-level domain. The second-level domain comprises a third proxy server, and the third proxy server in the second-level domain sends a first video monitoring service signaling to the first proxy server. And the first proxy server in the first-level domain receives the first video monitoring service signaling. The second-level domain is an upper-level domain or a lower-level domain of the first-level domain, for example, the second-level domain is an upper-level domain of the first-level domain. The first video monitoring service signaling carries a port identifier of a target domain. The port identification may be an IP (internet protocol Address) and/or a port number of the domain. In the embodiment of the present application, the port identification is not particularly limited.

Step 202: and the first proxy server selects a target signaling gateway from the signaling gateway cluster according to the residual load of each signaling gateway in the signaling gateway cluster.

The first proxy server may determine a signaling gateway node queue, and determine a target signaling gateway from the signaling gateway node queue, that is, the following first implementation manner; the first proxy server may also directly receive a gateway identifier of the target signaling gateway sent by the networking management server, and determine the target signaling gateway according to the gateway identifier, that is, the following second implementation manner.

In a first implementation manner, the step can be implemented by the following steps (1) to (3), including:

(1): the first proxy server determines a signaling gateway node queue.

The first proxy server may periodically determine and update the signaling gateway node queue. In this step, the first proxy server may obtain a stored signaling gateway node queue; alternatively, the first proxy server may determine the signaling gateway node queue when selecting the target signaling gateway.

The period for the first proxy server to determine and update the signaling gateway node queue can be set and changed as required. In the embodiments of the present application, this is not particularly limited.

The step of the first proxy server determining the signaling gateway node queue may be implemented by the following steps (1-1) to (1-3), including:

(1-1): the first proxy server determines a load balancing strategy of the first-level domain and acquires a plurality of residual load parameters of each signaling gateway in the signaling gateway cluster.

The first proxy server may obtain a plurality of remaining load parameters of each signaling gateway in the signaling gateway cluster in real time, or periodically obtain a plurality of remaining load parameters of each signaling gateway. The remaining load parameter may be any one of a remaining memory rate, a remaining memory size, a CPU (Central Processing Unit) remaining rate, a network remaining rate, a handle remaining rate, a thread remaining rate, and the like. For example, the remaining memory rate is the ratio of the remaining memory to the total memory. In the embodiment of the present application, the remaining load parameter is not particularly limited.

And the load balancing strategy comprises the weight corresponding to each residual load parameter. Wherein the sum of the weights corresponding to the plurality of residual load parameters is equal to 1. For example, the plurality of remaining load parameters are the memory remaining rate, the CPU remaining rate, the network remaining rate, the handle remaining rate, and the thread remaining rate, respectively, and the load balancing policy includes a first weight of the memory remaining rate, a second weight of the CPU remaining rate, a third weight of the network remaining rate, a fourth weight of the handle remaining rate, and a fifth weight of the thread remaining rate. Wherein the sum of the first weight to the fifth weight is equal to 1.

In a possible implementation manner, the first proxy server stores the load balancing policy, and the first proxy server directly obtains the stored load balancing policy. In another possible implementation, different signaling types correspond to different load balancing strategies; and the first proxy server stores the corresponding relation between the signaling type and the load balancing strategy. Accordingly, the step of the first proxy server determining the load balancing policy of the first-level domain may be: the first proxy server determines the signaling type of the first video monitoring service signaling, and obtains the load balancing strategy of the first video monitoring service signaling from the corresponding relation between the signaling type and the load balancing strategy according to the signaling type.

In the embodiment of the disclosure, the first proxy server formulates different load balancing strategies according to different signaling types, and the weights corresponding to each remaining load parameter in the different load balancing strategies are different. Therefore, the first proxy server can make different load balancing strategies according to the signaling type, and fully utilize various performance indexes of each signaling gateway so as to determine the target signaling gateway in real time. For example, when the video monitoring service signaling is to call a monitoring video in a certain time period, the remaining load parameters corresponding to the video monitoring service signaling are the memory remaining rate, the CPU remaining rate, the network remaining rate, the handle remaining rate, and the thread remaining rate. And the weights corresponding to the memory residual rate, the CPU residual rate, the network residual rate, the handle residual rate and the thread residual rate are all 0.2. When the video monitoring service signaling is downloading a video and audio file, the residual load parameters corresponding to the video monitoring service signaling are the residual memory rate, the residual CPU rate, the residual network rate, the residual handle rate and the residual thread rate. The weight corresponding to the memory surplus rate may be 0.25, the weight corresponding to the CPU surplus rate may be 0.2, the surplus load parameter corresponding to the network surplus rate may be 0.3, the weight corresponding to the handle surplus rate may be 0.1, and the weight corresponding to the thread surplus rate is 0.15.

It should be noted that the first proxy server includes a load balancing module, and the load balancing module determines a load balancing policy of the first-level domain.

Another point to be explained is that, in this step, the networking management server may also determine a signaling gateway node queue, and send the signaling gateway node queue to the first proxy server; the first proxy server receives the queue of signaling gateway nodes.

(1-2): the first proxy server determines a remaining load for each signaling gateway based on a load balancing policy and a plurality of remaining load parameters for each signaling gateway.

And the first proxy server determines the weight corresponding to each residual load parameter in the plurality of residual load parameters based on the load balancing strategy. And for each signaling gateway, the first proxy server performs weighted summation on each residual load parameter of the signaling gateway and the weight corresponding to each residual load parameter to obtain the residual load of the signaling gateway.

When the plurality of residual load parameters are respectively a memory residual rate, a CPU residual rate, a network residual rate, a handle residual rate and a thread residual rate, and the weights of the memory residual rate, the CPU residual rate, the network residual rate, the handle residual rate and the thread residual rate are respectively a first weight, a second weight, a third weight, a fourth weight and a fifth weight, for each signaling gateway, the first proxy server may determine the residual load of the signaling gateway through the following formula one.

The formula I is as follows: μ ═ a × M + b × C + C × N + d × H + e × T

μ is the remaining load of the signaling gateway, a is the first weight, b is the second weight, C is the third weight, d is the fourth weight, e is the fifth weight, M is the memory remaining rate, C is the CPU remaining rate, N is the network remaining rate, H is the handle remaining rate, T is the thread remaining rate, and a + b + C + d + e is 1.

(1-3): and the first proxy server sorts the gateway identifications corresponding to the multiple signaling gateways according to the residual load of each signaling gateway to obtain a signaling gateway node queue.

The signaling gateway node queue comprises a plurality of gateway identifications which are sequenced according to the residual load of each signaling gateway, and one signaling gateway corresponds to one gateway identification. Correspondingly, in the step, the first proxy server sorts each gateway identifier according to the remaining load of each signaling gateway to obtain a signaling gateway node queue; the first proxy server may sort the remaining loads of the signaling gateways corresponding to each gateway identifier from large to small, or from small to large. In the embodiments of the present application, this is not particularly limited.

(2): the first proxy server selects a gateway identification from the queue of signalling gateway nodes.

In a possible implementation manner, when the first video monitoring service signaling is one, the first proxy server selects a gateway identifier representing the signaling gateway with the largest residual load from the signaling gateway node queue. When the signaling gateway node queue is obtained by sequencing the residual load of the signaling gateway corresponding to each gateway identifier from large to small, and when the first video monitoring service signaling is one, the first proxy server selects the first gateway identifier from the signaling gateway node queue. And when the signaling gateway node queue is obtained by sequencing the residual load of the signaling gateway corresponding to each gateway identifier from small to large, the first proxy server selects the last gateway identifier from the signaling gateway node queue.

In another possible implementation manner, when the first video surveillance service signaling is multiple, for example, the first video surveillance service signaling is ten million-level first video surveillance service signaling, the first proxy server selects multiple gateway identifiers of multiple signaling gateways whose first number represents that the remaining load is greater than the preset load from the signaling gateway node queue. When the signaling gateway node queue is obtained by sequencing the residual load of the signaling gateway corresponding to each gateway identifier from large to small, and when the first video monitoring service signaling is a million-level first video monitoring service signaling, the first proxy server selects a first number of gateway identifiers from the signaling gateway node queue according to the sequence from front to back. When the signaling gateway node queue is obtained by sequencing from small to large according to the residual load of the signaling gateway corresponding to each gateway identifier, and when the first video monitoring service signaling is a million-level first video monitoring service signaling, the first proxy server selects a first number of gateway identifiers from the signaling gateway node queue according to the sequence from back to front.

In another possible implementation manner, the first proxy server may further determine an operating state of each signaling gateway; and selecting a gateway identifier with the residual load larger than the preset load in the idle state from the signaling gateway node queue according to the working state of each signaling gateway.

The size of the preset load may be set and changed as needed, and in the embodiment of the present disclosure, the size of the preset load is not specifically limited. For example, the preset load is 40%, 50%, or 55%. And when the preset load is 50%, the first proxy server selects a gateway identifier with the residual load more than 50% from the signaling gateway node queue.

(3): and the first proxy server selects a target signaling gateway corresponding to the gateway identifier from the signaling gateway cluster according to the gateway identifier.

When the number of the first video monitoring service signaling is one, the first proxy server selects a first gateway identifier in the signaling gateway node queue, selects a signaling gateway corresponding to the first gateway identifier from the signaling gateway cluster according to the first gateway identifier, and takes the signaling gateway as a target signaling gateway. And when the first proxy server selects the last gateway identifier in the signaling gateway node queue, selecting the signaling gateway corresponding to the last gateway identifier from the signaling gateway cluster according to the last gateway identifier, and taking the signaling gateway as a target signaling gateway. In the embodiments of the present application, this is not particularly limited.

When the first video monitoring service signaling is multiple, for example, the first video monitoring service signaling is ten million-level first video monitoring service signaling, the first proxy server selects a first number of gateway identifiers located in the signaling gateway node queue from front to back, selects a first number of signaling gateways corresponding to the first number of gateway identifiers from the signaling gateway cluster according to the first number of gateway identifiers, and takes the first number of signaling gateways as target signaling gateways. When the first video monitoring service signaling is ten-million-level first video monitoring service signaling, the first proxy server selects a first number of gateway identifiers located in the signaling gateway node queue from back to front, selects a first number of signaling gateways corresponding to the first number of gateway identifiers from the signaling gateway cluster according to the first number of gateway identifiers, and takes the first number of signaling gateways as target signaling gateways.

It should be noted that, in the embodiment of the present disclosure, all signaling gateways whose remaining loads are greater than the preset load may be taken as target signaling gateways. The number of target signaling gateways may be one or more, one when one signaling gateway is selected from the signaling gateway cluster, and multiple when multiple signaling gateways are selected from the signaling gateway cluster. In the embodiment of the present disclosure, the number of target signaling gateways is not specifically limited.

In a second implementation manner, the first-level domain further includes: and a network management server. Step 202 may also include: the first proxy server sends a first obtaining request to the networking management server, wherein the first obtaining request is used for obtaining a gateway identifier of a target signaling gateway for processing a first video monitoring service signaling. The network management server receives the first acquisition request, determines a gateway identifier of a target signaling gateway, and sends the gateway identifier of the target signaling gateway to the first proxy server, the first proxy server receives the gateway identifier, and selects the target signaling gateway from the signaling gateway cluster according to the gateway identifier, and the target signaling gateway is selected by the network management server according to the residual load of each signaling gateway.

The process of the networking management server determining the gateway identification of the target signaling gateway may include: the method comprises the steps that a networking management server obtains the residual load parameters of each signaling gateway in real time, a first proxy server sends a load balancing strategy formulated by a load balancing module to the networking management server, the networking management server determines the residual load of each signaling gateway based on the residual load parameters and the load balancing strategy of each signaling gateway, and selects a gateway identification corresponding to the signaling gateway with the residual load larger than the preset load.

The step of determining the remaining load of each signaling gateway by the networking management server based on the remaining load parameter and the load balancing policy of each signaling gateway is similar to the step of determining the remaining load of each signaling gateway by the first proxy server based on the remaining load parameter and the load balancing policy of each signaling gateway, and is not described herein again.

The residual load of each signaling gateway is determined through the networking management server, and the gateway identification corresponding to the signaling network with the residual load larger than the preset load is sent to the first proxy server, so that the situation that the first proxy server determines the residual load according to the residual load parameters of each signaling gateway and selects the target signaling gateway from the signaling gateway cluster is avoided, and the speed of the first proxy server for acquiring the target signaling gateway is improved.

Step 203: and the first proxy server sends a first processing instruction to the target signaling gateway.

The method comprises the steps that a first proxy server sends a first processing instruction to a target signaling gateway after determining the target signaling gateway, the first processing instruction carries a first video monitoring service signaling, the first processing instruction is used for indicating the target signaling gateway to process the first video monitoring service signaling, after a second video monitoring service signaling is obtained, the second video monitoring service signaling is forwarded to a second proxy server, the second proxy server sends the second video monitoring service signaling to a third-level domain, and the third-level domain is a lower-level domain or an upper-level domain of a first-level domain.

Step 204: and the target signaling gateway receives the first processing instruction, processes the first video monitoring service signaling in the first processing instruction to obtain a second video monitoring service signaling, and forwards the second video monitoring service signaling to the second proxy server.

The step of processing the first video monitoring service signaling by the target signaling gateway in this step to obtain the second video monitoring service signaling can be realized by the following steps (1) to (3), and includes:

(1): and the target signaling gateway performs first service logic processing on the first video monitoring service signaling to obtain a first signaling message.

The target signaling gateway comprises a logic service module and a protocol service module; the logic service module performs first service logic processing on the first video monitoring service signaling to obtain a first signaling message, and sends the first signaling message to the protocol service module.

The protocol in the target signaling gateway is different from that of the second proxy server, so before the target signaling gateway sends the first video monitoring service signaling to the second proxy server, protocol conversion and the like need to be performed on the first video monitoring service signaling, and the protocol conversion is completed by the protocol service module. The protocol of the first video monitoring service signaling is different from the protocol of the protocol service module, and the protocol service module cannot directly convert the protocol of the first video monitoring service signaling, so that before the protocol service module performs protocol conversion on the first video monitoring service signaling, the protocol service module needs to perform first service logic processing on the first video monitoring service signaling through the logic service module to obtain a first signaling message, and the logic service module sends the first signaling message to the protocol service module, wherein the protocol of the first signaling message is the same as the protocol in the protocol service module.

It should be noted that each signaling gateway includes a logic service module and a protocol service module.

(2): and the target signaling gateway performs protocol encapsulation on the first signaling message to obtain a second signaling message.

The protocol service module receives the first signaling message, performs protocol encapsulation on the first signaling message to obtain a second signaling message, and sends the second signaling message to the logic service module.

The protocol service module performs protocol encapsulation, analysis and recombination on the first signaling message, and sends an obtained second signaling message to the logic service module, wherein the protocol of the second signaling message is different from that in the second proxy server and is the same as that in the target signaling gateway, so that the protocol service module needs to send the second signaling message to the logic service module first.

(3): and the target signaling gateway performs second service logic processing on the second signaling message to obtain a second video monitoring service signaling.

And the logic service module performs second service logic processing on the second signaling message to obtain a second video monitoring service signaling. And the logic service module acquires the port identification of the target domain from the first video monitoring service signaling, and loads the port identification of the target domain in the second video monitoring service signaling.

The first video monitoring service signaling is processed to obtain a second video monitoring service signaling, and the protocol of the second video monitoring service signaling is the same as that in the second proxy server, so that the target signaling gateway can send the obtained second video monitoring service signaling to the second proxy server.

It should be noted that, after the step 204 is executed, the step of sending the second video surveillance service signaling to the third-level domain by the second proxy server in the step 207 may be directly executed. Or, after step 204 is executed, step 205 may also be executed to verify the third-level domain; when the verification is passed, step 207 is executed, thereby improving security.

Step 205: and the second proxy server receives the second video monitoring service signaling and sends a verification instruction to the database server.

In this step, the first-level domain further includes: a database server for authenticating the third level domain. Correspondingly, after receiving the second video monitoring service signaling, the second proxy server sends a verification instruction to the database server, wherein the verification instruction is used for verifying whether the port identifier of the third-level domain is stored in the database server. Different domains correspond to different port identities. The third level domain is a lower level domain or an upper level domain of the first level domain.

It should be noted that, when the second-level domain is a higher-level domain of the first-level domain, the third-level domain is a lower-level domain of the first-level domain; when the second-level domain is a lower-level domain of the first-level domain, the third-level domain is an upper-level domain of the first-level domain.

Step 206: the database server receives the verification instruction, and sends a confirmation message to the second proxy server when the port identification of the third-level domain is stored in the database server.

The database in the database server stores the port identifiers of the verified domains in advance, and one domain corresponds to one port identifier. The verification instruction carries a port identifier of a third-level domain, and after receiving the verification instruction, the database server searches whether the port identifier of the third-level domain is stored in the database or not according to the port identifier of the third-level domain carried in the verification instruction. When the port identification of the third-level domain exists, sending a confirmation message to the second proxy server; when not present, the validation instruction is discarded.

Step 207: and the second proxy server receives the confirmation message and sends a second video monitoring service signaling to the third-level domain.

In a possible implementation manner, the second video monitoring service signaling carries a port identifier of the target domain, after the second proxy server receives the confirmation message sent by the database server, the port identifier of the target domain is obtained from the second video monitoring service signaling, the target domain corresponding to the port identifier is determined according to the port identifier of the target domain and the stored domain information, and the target domain is used as the third-level domain. And the second proxy server sends a second video monitoring service signaling to the third-level domain according to the port identifier of the third-level domain. When the second-level domain is a superior domain of the first-level domain, the third-level domain is a subordinate domain of the first-level domain; when the second domain is a lower domain of the first domain, the third domain is an upper domain of the first domain.

It should be noted that, when the video monitoring service corresponding to the first video monitoring service signaling or the second video monitoring service signaling is video and audio on demand in real time, and when a session connection needs to be established during the video and audio on demand in real time, the first proxy server and the second proxy server further have a path tracking function, which can maintain sessions between both parties of the video and audio on demand.

The embodiment of the application provides a method for processing video monitoring service signaling, wherein a signaling gateway cluster is arranged in a first-level domain, and the signaling gateway cluster comprises a plurality of signaling gateways. When the first proxy server in the first-level domain receives the first video monitoring service signaling of the second-level domain, a target signaling gateway is selected from the signaling gateway cluster according to the residual load of each signaling gateway in the signaling gateway cluster, so that various performance indexes of each signaling gateway can be fully utilized, and the rationality of selecting the target signaling gateway is improved. And the target signaling gateway performs video monitoring processing on the first video monitoring service signaling, so that the processing speed and efficiency of the video monitoring service signaling are improved, and the performance of the video monitoring service signaling processing system for processing the video monitoring service signaling is enhanced.

It should be noted that, when the scale of the first video monitoring service signaling is ten million scale or even larger scale, the effect of improving the system performance is particularly obvious, that is, the method provided by the embodiment of the present disclosure increases the performance of the video monitoring service signaling processing system processing the video monitoring service signaling in the scenario of ten million scale video resource networking.

An embodiment of the present application provides a method for processing a video surveillance service signaling, and with reference to fig. 3, the method is applied to a first-level domain in a system for processing a ten-million-level video surveillance service signaling under the networking of ten-million-level video resources, where the first-level domain includes: the system comprises a first proxy server and a signaling gateway cluster, wherein the signaling gateway cluster comprises a plurality of signaling gateways; in the embodiment of the present application, a second-level domain sends a first video monitoring service signaling to a first-level domain, and a target signaling gateway of the first-level domain performs video monitoring processing on the first video monitoring service signaling, which is taken as an example for description, the method includes:

step 301: the first proxy server receives a first video monitoring service signaling of a second-level domain in the video monitoring service signaling processing system.

Step 302: and the first proxy server selects a target signaling gateway from the signaling gateway cluster according to the residual load of each signaling gateway in the signaling gateway cluster.

Steps 301 to 302 are the same as steps 201 to 202, respectively, and are not described herein again.

Step 303: and the first proxy server sends a second processing instruction to the target signaling gateway.

And after determining the target signaling gateway, the first proxy server sends a second processing instruction to the target signaling gateway, wherein the second processing instruction carries the first video monitoring service signaling, and the second processing instruction is used for indicating the target signaling gateway to perform video monitoring processing on the first video monitoring service signaling.

Step 304: and the target signaling gateway receives the second processing instruction, processes the first video monitoring service signaling and obtains a second video monitoring service signaling.

The step of processing the first video monitoring service signaling by the target signaling gateway to obtain the second video monitoring service signaling is the same as the step of processing the first video monitoring service signaling by the target signaling gateway in step 204 to obtain the second video monitoring service signaling, and details are not repeated here.

Step 305: and the target signaling gateway executes the video monitoring service corresponding to the second video monitoring service signaling.

The video monitoring service may be any video monitoring service, for example, the video monitoring service is to obtain a monitoring video. When the video monitoring service is to acquire a monitoring video, the target signaling gateway acquires the monitoring video corresponding to the second video monitoring service signaling, and sends the monitoring video to the first proxy server. And after receiving the monitoring video, the first proxy server sends the monitoring video to the second-level domain.

The embodiment of the application provides a method for processing video monitoring service signaling, wherein a signaling gateway cluster is arranged in a first-level domain, and the signaling gateway cluster comprises a plurality of signaling gateways. When the first proxy server in the first-level domain receives the first video monitoring service signaling of the second-level domain, a target signaling gateway is selected from the signaling gateway cluster according to the residual load of each signaling gateway in the signaling gateway cluster, so that various performance indexes of each signaling gateway can be fully utilized, and the rationality of selecting the target signaling gateway is improved. And the target signaling gateway performs video monitoring processing on the first video monitoring service signaling, so that the processing speed and efficiency of the video monitoring service signaling are improved, and the performance of the video monitoring service signaling processing system for processing the video monitoring service signaling is enhanced.

It should be noted that, when the scale of the first video monitoring service signaling is ten million scale or even larger scale, the effect of improving the system performance is particularly obvious, that is, the method provided by the embodiment of the present disclosure increases the performance of the video monitoring service signaling processing system processing the video monitoring service signaling in the scenario of ten million scale video resource networking.

The embodiment of the present application provides a method for processing a video monitoring service signaling, refer to fig. 4, and is applied to a first proxy server in a first-level domain in a ten-million-level video monitoring service signaling processing system under ten-million-level video resource networking, where the method is described by taking as an example that a second-level domain sends a first video monitoring service signaling to the first-level domain, and the first-level domain sends a second video monitoring service signaling to a third-level domain, and the method includes:

step 401: the first proxy server receives a first video monitoring service signaling of a second-level domain in the video monitoring service signaling processing system.

Step 402: and the first proxy server selects a target signaling gateway from the signaling gateway cluster according to the residual load of each signaling gateway in the signaling gateway cluster.

Steps 401 to 402 are the same as steps 201 to 202, respectively, and are not described herein again.

Step 403: and the first proxy server performs video monitoring processing on the first video monitoring service signaling through the target signaling gateway.

In a first implementation manner, the first-level domain further includes: a second proxy server.

When the first-level domain exists in the upper-level domain and the lower-level domain at the same time, namely the second-level domain and the third-level domain exist at the same time, the first proxy server sends a first processing instruction to the target signaling gateway, the first processing instruction is used for indicating the target signaling gateway to process the first video monitoring service signaling, after the second video monitoring service signaling is obtained, the target signaling gateway forwards the second video monitoring service signaling to the second proxy server, and the second proxy server sends the second video monitoring service signaling to the third-level domain. The third-level domain is a lower-level domain or an upper-level domain of the first-level domain.

In the first implementation manner, the step of processing the first video monitoring service signaling by the target signaling gateway to obtain the second video monitoring service signaling is the same as the step of processing the first video monitoring service signaling by the target signaling gateway in step 204 to obtain the second video monitoring service signaling, and details are not repeated here.

In a second implementation manner, when the first-level domain only has the upper-level domain and the lower-level domain does not exist, that is, when only the second-level domain exists, the first proxy server sends a second processing instruction to the target signaling gateway, where the second processing instruction is used to instruct the target signaling gateway to process the first video monitoring service signaling, and after the second video monitoring service signaling is obtained, the video monitoring service corresponding to the second video monitoring service signaling is executed. For example, the video surveillance service is to obtain surveillance video. The target signaling gateway obtains the monitoring video corresponding to the second video monitoring service signaling and sends the monitoring video to the first proxy server, and the first proxy server receives the monitoring video returned by the target signaling gateway and sends the monitoring video to the second-level domain.

When the first-level domain only has a lower-level domain and does not have a higher-level domain, that is, when only the third-level domain exists, the process of sending the video monitoring service signaling to the third-level domain by the first-level domain is similar to the process of sending the first video monitoring service signaling to the first-level domain by the second-level domain, and details are not repeated here.

The embodiment of the application provides a method for processing video monitoring service signaling, wherein a signaling gateway cluster is arranged in a first-level domain, and the signaling gateway cluster comprises a plurality of signaling gateways. When the first proxy server in the first-level domain receives the first video monitoring service signaling of the second-level domain, a target signaling gateway is selected from the signaling gateway cluster according to the residual load of each signaling gateway in the signaling gateway cluster, so that various performance indexes of each signaling gateway can be fully utilized, and the rationality of selecting the target signaling gateway is improved. And the target signaling gateway performs video monitoring processing on the first video monitoring service signaling, so that the processing speed and efficiency of the video monitoring service signaling are improved, and the performance of the video monitoring service signaling processing system for processing the video monitoring service signaling is enhanced.

It should be noted that, when the scale of the first video monitoring service signaling is ten million scale or even larger scale, the effect of improving the system performance is particularly obvious, that is, the method provided by the embodiment of the present disclosure increases the performance of the video monitoring service signaling processing system processing the video monitoring service signaling in the scenario of ten million scale video resource networking.
