Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Example one
Fig. 2 is a flowchart of a gateway selection method in a service system according to an embodiment of the present invention, where the method is applicable to a situation where a gateway is selected to improve audio/video accessibility of an external device when the gateways are stacked and deployed in an audio/video conference, the method may be executed by a gateway selection device in the service system, the device may be implemented in a software or hardware manner, and the device may be integrated in a server, such as an application server in the service system. As shown in fig. 2, the method specifically includes:
and step 110, acquiring a service request of the target client aiming at the target external equipment.
The service system comprises a plurality of external devices and a plurality of gateway servers, and each gateway server is in communication connection with each external device.
The target client may initiate a service request for the external device. The service request can be audio and video conference, call and the like to the target external device. In the service system, the gateway server, the external device, the signaling server and the application server may be deployed in the main platform server to jointly implement the service request of the client. In the embodiment of the present invention, the main platform server may implement information configuration of the external device and the gateway server, such as type information and registration information. The main platform server can realize that each gateway server establishes communication connection with each external device. The signaling server may receive a service request initiated by the target client and forward the service request to the application server.
And step 120, determining a target gateway server matched with the target external device according to the first online gateway list.
And recording the current online gateway server in the service system in real time in the first online gateway list. Any gateway server in the first online gateway list that is currently online may be determined as a target gateway server that matches the target peripheral device.
In order to reduce the load of a single gateway server, in an implementation manner of the embodiment of the present invention, optionally, determining, according to the first online gateway list, a target gateway server that matches the target external device includes: and according to the service request, determining a target gateway server matched with the target external equipment from the first online gateway list in a polling index mode.
The polling index is used for scheduling the gateway servers in sequence according to the sequence of the gateway servers in the first online gateway list, and if the current gateway server is scheduled, scheduling the next gateway server; when all gateway servers are scheduled, the first gateway server may be scheduled from the head. According to the technical scheme of the embodiment of the invention, the target gateway server is determined from the first online gateway list in a polling index mode, so that the problem of large load of a single gateway server caused by repeated and single calling of the gateway server can be avoided.
In order to accurately determine whether the gateway server is online, in an implementation manner of the embodiment of the present invention, optionally, when it is detected that the first gateway server in the service system is converted from the offline state to the online state, the first gateway server is added to the first online gateway list; and when detecting that the second gateway server in the service system is converted from the online state to the offline state, removing the second gateway server from the first online gateway list.
The gateway server may initiate registration to a signaling server in the service system, and the signaling server may send registration on-line information of the gateway server to the application server. The application server may add the first gateway server to the first online gateway list when there is a first gateway server in an online state. When the second gateway server is offline, the signaling server may send offline information of the second gateway server to the application server, and the application server may remove the second gateway server from the first online gateway list. The first online gateway list can record the current online gateway server according to the real-time online or offline state of the gateway server, so that an available gateway server can be determined for the target external device conveniently. The off-line of the gateway server may be caused by various reasons, for example, an abnormality, a failure, or a registered off-line of the gateway server.
And step 130, sending the service request to a target gateway server so that the target client accesses the target external device through the target gateway server.
When the application server matches the target gateway server for the target external device according to the first online gateway list, the application server may send a service request of the target client to the target external device to the target gateway server. When the service request is an audio and video conference or a call, the target gateway server can perform operations such as encoding and decoding on audio and video streams shot by the target external device, push the audio and video streams of the target external device to the target client, and achieve communication between the target client and the target external device.
On the basis of the foregoing embodiment, optionally, the method further includes: when detecting that the first online gateway list is switched from a blank state to a state with gateway information, uniformly simulating online all the external equipment, and informing a client subscribing the external equipment to update the state so as to indicate the client to initiate a service request aiming at the external equipment simulating online; and/or
When the first online gateway list is detected to be switched to a blank state from a state with gateway information, all the external devices are subjected to unified simulation offline, and a client subscribing the external devices is informed to perform state updating so as to indicate the client to stop initiating a service request aiming at the external devices subjected to simulation offline.
In a specific implementation manner of the embodiment of the present invention, based on the configuration of the host platform server to the external device and the gateway servers, each gateway server may establish a communication connection with each external device. When the gateway server is on line, namely the first on-line gateway list is not in a blank state, and when the gateway information state of the gateway server exists, all the external devices can be uniformly simulated on line. When determining that the gateway information state exists in the first online gateway list according to the signaling server, the application server may notify the client subscribing to the state information of the external device, and the external device simulates online. The client can update the state of the external device to be online and can initiate a service request to the online external device. The simulation online may mean that a gateway server may provide communication connection for the external device, and the external device may be accessed. The simulated presence may be a non-real presence and may be converted to a real presence after determining the gateway server and establishing the communication connection.
In another specific implementation manner of the embodiment of the present invention, when the application server determines that the first online gateway list does not have the gateway information status according to the status of the gateway server sent by the signaling server, and the first online gateway list is in a blank status, the application server may determine that the external device is a simulated offline, and may notify the client subscribing to the external device status information that the external device is a simulated offline. When the external device is off-line, the client cannot make service requests, such as video calls, conferences and the like, for the external device. The simulation offline may mean that no gateway server exists and can provide communication connection for the external device, and the external device cannot be accessed. The simulated offline state can be a non-real offline state, and when the main platform server determines that the external device is offline, the simulated offline state can be determined as a real offline state.
According to the technical scheme of the embodiment, a service request of a target client aiming at target external equipment is obtained; determining a target gateway server matched with the target external equipment according to the first online gateway list; the service request is sent to the target gateway server, so that the target client accesses the target external equipment through the target gateway server, the selection problem of the gateway server during stacking and deployment is solved, the relevance between the external equipment and the gateway server is reduced, the normal use probability of the external equipment is improved, the external equipment can be matched with the gateway server according to the service request, and the service request is convenient for a user; and the load of a single gateway server is reduced, and the online state of the gateway server is updated in real time, so that accurate information support is provided for realizing the service request.
Example two
Fig. 3a is a flowchart of a gateway selection method in a service system according to a second embodiment of the present invention. The present embodiment is a further refinement of the above technical solutions, and the technical solutions in the present embodiment may be combined with various alternatives in one or more of the above embodiments. As shown in fig. 3a, the method specifically includes:
and step 210, acquiring a service request of the target client to the target external device.
The service system comprises a plurality of external devices and a plurality of gateway servers, and each gateway server is in communication connection with each external device.
The method comprises the steps that a gateway server in an online state currently in a service system is recorded in a first online gateway list in real time; and recording a weight value corresponding to the gateway server in the online state in real time in the first online gateway list. The weight value may be determined according to the service processing paths that the gateway server may simultaneously support, for example, the higher the service processing paths that the gateway server may simultaneously support, the larger the weight value. For example, the gateway server may simultaneously support 16, 8, or 2 paths of traffic processing, and the corresponding weight value may be 16, 8, or 2, and the like.
The gateway servers recorded in the first online gateway list are dynamically changed, for example, when the gateway servers are online, offline or abnormally down, the first online gateway list is changed. In the embodiment of the application, the gateway server in the first online gateway list and the corresponding weight value are copied in the second online gateway list of the local thread, so that the online gateway list according to which the local thread is matched with the target gateway server for the target external device according to the service request is static can be ensured. It is also possible to avoid that the first online gateway list is modified by multiple threads.
For example, a local variable serverSet may be newly created to copy the gateway server and the corresponding weight value in the first online gateway list to the local thread, so as to implement static locking on the first online gateway list.
In an implementation manner of the embodiment of the present invention, optionally, when it is detected that a first gateway server in a service system is converted from an offline state to an online state, the first gateway server is added to a first online gateway list; and when detecting that the second gateway server in the service system is converted from the online state to the offline state, removing the second gateway server from the first online gateway list.
When the gateway server updates in the first online gateway list, the corresponding weight value may be updated synchronously. For example, when a first gateway server is added to the first online gateway list, the weight value of the first gateway server may be added synchronously; when the second gateway server is removed from the first online gateway list, the weight value of the second gateway server may be removed synchronously. The weight value may be configured in the main platform server in advance according to the hardware performance of the gateway server.
And step 230, determining the number of the service processing paths of each gateway server according to the gateway servers in the second online gateway list and the corresponding weight values.
The application server may convert the weight value into the number of the service processing channels according to a mapping relationship or an operation relationship between the weight value in the second online gateway list and the number of the service processing channels. Illustratively, the weight value is 16, and the number of traffic processing channels is 16.
And 240, generating a third online gateway list according to the number of the service processing paths of each gateway server.
And the third online gateway list records the sequencing of each gateway server and the corresponding service processing path. In this embodiment, the service processing paths corresponding to the number of service processing paths of each gateway server may be sorted according to the order of the gateway servers in the second online gateway list, so as to generate a third online gateway list. Or, the gateway servers in the second online gateway list may be reordered according to the descending order according to the number of the service processing paths, and if the number of the service processing paths is the same, the gateway servers in the second online gateway list may be reordered according to the order in the second online gateway list; and sequencing the service processing channels of the gateway servers according to the reordered gateway servers and the number of the corresponding service processing channels to generate a third online gateway list. The latter way of generating the third online gateway list may facilitate the gateway server with good hardware performance to preferentially obtain the service request, process the service request in time, and facilitate quick execution of the service request.
And step 250, according to the service request, determining a target gateway server matched with the target external device and a target service processing path from the third online gateway list in a polling index manner.
The manner of polling index is the same as that of the previous embodiment, and is not described herein again. The difference between this embodiment and the foregoing embodiment is that the polling index of this embodiment is the gateway server and the corresponding traffic processing path.
Illustratively, service request 1 requires 8 traffic processing paths, and service request 2 requires 8 traffic processing paths. In the third online gateway list, there are 1-16 paths for traffic processing by the gateway server a and 1-8 paths for traffic processing by the gateway server B. According to the specific situation of the polling index, 1-8 traffic processing paths of the gateway server a can be allocated to the traffic request 1, and 9-16 traffic processing paths of the gateway server a can be allocated to the traffic request 2. In the next service request, the service processing path of the gateway server B may be allocated.
In an implementation manner of the embodiment of the present invention, optionally, determining, according to the service request, a target gateway server and a target service processing path that are matched with the target external device from the third online gateway list in a polling index manner, includes: and performing polling index by adopting an atomic operation class, and determining a target gateway server matched with the target external equipment and a target service processing path from the third online gateway list according to the service request.
The atomic operation (atomiciInteger) class can ensure that when multiple threads access shared data concurrently, the shared data is only used by one or some threads at the same time, and can ensure the concurrency security when the threads perform polling indexing.
And step 260, sending the service request to a target gateway server so that the target client accesses the target external device through the target gateway server.
On the basis of the foregoing embodiment, optionally, the method further includes: when the first online gateway list is detected to be switched from a blank state to a state with gateway information, performing unified simulation online on all external equipment, and notifying a client subscribing the external equipment to perform state updating so as to indicate the client to initiate a service request aiming at the external equipment simulating online; and/or
When the first online gateway list is detected to be switched from the state with the gateway information to the blank state, all the external devices are subjected to unified simulated offline, and the client subscribing the external devices is informed to perform state updating so as to indicate the client to stop initiating the service request aiming at the external devices subjected to simulated offline.
According to the technical scheme of the embodiment of the invention, a service request of a target client aiming at target external equipment is obtained; copying the gateway server in the first online gateway list and the corresponding weight value into a second online gateway list of the local thread; determining the number of service processing paths of each gateway server according to the gateway servers in the second online gateway list and the corresponding weight values; generating a third online gateway list according to the number of service processing paths of each gateway server; according to the service request, determining a target gateway server matched with the target external equipment and a target service processing path from the third online gateway list in a polling index mode; the service request is sent to the target gateway server, so that the target client accesses the target external device through the target gateway server, the selection problem when the gateway servers are stacked and deployed is solved, the matching of the external device with the gateway server according to the service request is realized, the processing capacity of the gateway server is fully utilized, and the effect of ensuring the safety of concurrent service requests is achieved.
Fig. 3b is a schematic diagram illustrating an implementation manner of a gateway selection method in a service system according to a second embodiment of the present invention. As shown in fig. 3b, the gateway server may initiate gateway registration with the signaling server, and the gateway server may be on-line after successful registration. The signaling server may send the on-line of the gateway server to the application server. When the client initiates a service request for the external device, the signaling server may forward the service request to the application server. The application server can determine a target gateway server according to the online state of the gateway server and send the service request to the target gateway processor.
Illustratively, as shown in fig. 3B, there are a gateway server a and a gateway server B, and when the gateway server a and the gateway server B are online, the application server may send the service request to the gateway server a according to the polling index of the AtomicInteger class. When the gateway server a logs off and the client initiates the service request again, the application server may send the service request to the gateway server B. The target gateway server can be determined to process the service between the client and the external equipment according to the real-time online updating condition of the gateway server, so that the success rate of service processing is improved, and the user experience is improved.
