The embodiment of the application provides a path reallocation method, wherein an execution main body of the path reallocation method is computer equipment, and the network service system is applied to the computer equipment. The network traffic system may include a routing center, a plurality of network function entities, a plurality of controllers, and at least one listener. The plurality of network function entities are respectively connected with the controllers in the plurality of controllers, and the plurality of network function entities and the plurality of controllers are respectively connected with the routing center. In some embodiments of the present application, the plurality of network function entities may include a first network function entity, and the plurality of controllers includes a first controller.
In the embodiment of the present Application, the Network function entity is configured to receive a service request sent by a terminal device, and may be applied to Network Address Translation (NAT), Carrier/telecommunication level NAT (CGN), a Firewall (FW, Firewall), an Application switching controller (ADC, Application discovery controller), Application Performance Monitoring (APM), a Content Distribution Network (CDN, Content Distribution Network), a Uniform Resource Locator (URL) filter, which is not limited to this, of course; the network function entity may be further configured to receive a data stream of the terminal device, and analyze the received data stream.

Specifically, in some embodiments of the present application, there may be a plurality of network function entities, and a plurality of controllers, and one network function entity may be connected to a plurality of controllers to form a plurality of different paths for performing different service processes.
In general, the path corresponding to each network function entity is usually configured in advance, that is, a plurality of different controllers connected to different network function entities are usually configured in advance. However, in the actual using process, the situation of disconnection inevitably occurs, so that the service flow cannot be normally performed, and therefore, the disconnected network function entity needs to be redistributed, and the disconnected network function entity is connected with other normal controllers.
In the network service system, the service requests of the same type can be processed among a plurality of different paths, so that the problem of low processing efficiency because all the service requests of the same type are processed on one path is avoided. Therefore, when a certain path is disconnected, other paths for processing the same type of service requests can be searched, and connection is established between the network functional entity and the controller, so that service interruption caused by disconnection is avoided.
As shown in fig. 2, which is a schematic flow chart of an embodiment of a path reallocation method in the embodiment of the present application, the path reallocation method includes:
21. a first target controller associated with a first network function entity is determined.
In the embodiment of the present application, the network function entities are all connected to the controller, and the network function entities may process different service requests under the control of different controllers. And typically the controller associated with one network function entity is configured in advance, so that the first target controller associated with the first network function entity can be determined.
22. The network unit judges whether the first network functional entity and the first target controller are disconnected.
After the first target controller associated with the first network functional entity is determined, it is further required to determine whether the first network functional entity and the first target controller are disconnected, and the network functional entity can normally operate only if the first network functional entity and the first target controller are not disconnected.
In the embodiment of the present application, the data service system further includes a network unit, and the network unit may be used to determine whether the first network functional entity and the first target controller are disconnected. Specifically, the network unit is at least one listener or a plurality of network function entities; namely, a monitor can be added in the data service system, and the monitor is utilized to monitor whether the connection between the network functional entity and the target controller is broken; or a plurality of network functional entities monitor whether the network functional entities are disconnected with the controller.
23. And if the line is broken, the first network functional entity generates a prompt signal and sends the prompt signal to the routing center.
When the network unit monitors that the first network functional entity and the first target controller are disconnected, the first network functional entity can generate a prompt signal and send the prompt signal to the routing center, and the routing center is prompted to redistribute the controller to the first network functional entity, so that the first network functional entity works normally again.
24. And after receiving the prompt signal, the routing center acquires the priorities of the plurality of service requests.
25. And selecting a normal second controller from the plurality of controllers according to the priority, and reallocating the second controller to establish connection with the first network function entity.
In the embodiment of the present application, after the routing center receives the notification signal from the first network functional entity, the controller needs to be reassigned to the first network functional entity, so that the first network functional entity operates normally again.
According to the path reallocation method, whether the network function entity and the controller are disconnected or not is monitored, and if the network function entity and the controller are disconnected, the routing center reallocates the controller to be connected with the network function entity, so that the interruption of data service transmission caused by the disconnection between the network function entity and the controller is avoided.
In some embodiments of the present application, the network element may be at least one listener, i.e. the network traffic system may comprise at least one listener; and at least one listener is connected to a plurality of network function entities. The at least one listener may thus be utilized to determine whether a disconnection between the first network function entity and the first target controller is occurring.
Fig. 3 is a schematic flow chart of an embodiment of determining whether a network function entity and a controller are disconnected according to the present application. In an embodiment of the present application, determining whether a network function entity and a controller are disconnected may include:
31. the at least one listener regularly transmits the first monitoring signal to the first network function entity.
32. If the at least one listener does not receive the first feedback signal from the first network function entity within the predetermined time period, the disconnection between the first network function entity and the first target controller is confirmed.
Specifically, in the embodiment of the present application, there may be one listener, where the listener is connected to the first network function entity, and the listener may be used to monitor whether a line between the first network function entity and the first target controller is disconnected.
In the above embodiment, the listener may send the first monitoring signal to the first network function entity at regular time, and if the first network function entity and the first target controller are not disconnected, the first network function entity should feed back the first monitoring signal under the control of the first target controller; that is, the first network function entity feeds back the first feedback signal to the listener. If the listener receives the first feedback signal within the preset time period, the listener may consider that the first network function entity and the first target controller are not disconnected.
Similarly, if the first network function entity is disconnected from the first target controller, the first network function entity cannot receive the first monitoring signal, and even cannot generate a first feedback signal corresponding to the first monitoring signal under the control of the first target controller and feed the first feedback signal back to the monitor. Therefore, if the listener does not receive the first feedback signal from the first network function entity within the predetermined time period, the listener can identify the disconnection between the first network function entity and the first target controller.
In the above embodiment, if the listener receives the first feedback signal but does not receive the first feedback signal within the preset time period, the listener may consider that the first network functional entity is not disconnected from the first target controller, but another fault occurs, so that the sending of the first feedback signal is delayed. At this time, the listener can generate a prompt signal to prompt the operator to check the network service system and remove the fault.
In other embodiments of the present application, the network unit may be a plurality of network function entities, that is, the plurality of network function entities themselves monitor and control whether the connection between the network unit and the controller is broken. In this embodiment, the determining, by the network unit, whether the first network function entity and the first target controller are disconnected may include:
the first network functional entity sends a second monitoring signal to the first target controller at regular time; if the first network function entity does not receive the second feedback signal from the first target controller within the preset time period, determining the broken line between the first network function entity and the first target controller.
Specifically, the first network function entity may send the second monitoring signal to the first target controller at regular time, and if the first network function entity and the first target controller are not disconnected, the first target controller may process the second monitoring signal, generate the second feedback signal, and send the second feedback signal to the first network function entity. If the first network functional entity receives the second feedback signal within the preset time period, the first network functional entity may consider that the first network functional entity and the first target controller are not disconnected.
Similarly, if the first network function entity is disconnected from the first target controller, the first target controller cannot receive the second monitoring signal at all, and further cannot generate a second feedback signal corresponding to the second monitoring signal and feed the second feedback signal back to the first network function entity. Therefore, if the first network function entity does not receive the second feedback signal from the first target controller within the preset time period, the first network function entity can identify the disconnection between itself and the first target controller.
Also in the foregoing embodiment, if the first network function entity receives the second feedback signal, but does not receive the second feedback signal within the preset time period, the first network function entity may consider that the first network function entity is not disconnected from the first target controller, but another fault occurs, so that the sending of the second feedback signal is delayed. At this time, the first network functional entity may generate a prompt signal to prompt an operator to check the network service system to remove the fault.
It should be noted that, in the above embodiment, the length of the specific time period of the preset time period may be changed according to the actual use condition of the network service system, and is not limited herein.
In other embodiments of the present application, there may be multiple instances of disconnection throughout the network service system; as shown in fig. 4, a schematic flow chart of another embodiment of the path reallocation method provided in the embodiment of the present application is shown. In this embodiment, the path reallocation method may include:
41. a second target controller associated with each of the plurality of network functional entities is determined.
42. The network unit judges whether the connection between each network functional entity and the second target controller is broken.
43. And if a plurality of broken lines exist in the network service system, determining a target network functional entity of the broken lines.
44. And after receiving the prompt signal, the routing center acquires the priorities of the plurality of service requests.
45. And the routing center redistributes the normal second controllers to be respectively connected with the disconnected target network functional entities according to the priority.
Specifically, the routing center may be utilized to determine a second target controller respectively associated with each network functional entity; meanwhile, the network unit can be used for respectively judging whether the line between each network functional entity and the second target controller is broken. Specifically, the specific process of determining whether the connection between each network functional entity and the second target controller is disconnected by using the network unit may refer to the step of determining whether the connection between the first network functional entity and the first target controller is disconnected, and details thereof are not repeated here.
If the network unit monitors that a plurality of broken lines exist in the whole network service system, the target network functional entities of the broken lines need to generate prompt signals and send the prompt signals to the routing center. After receiving the prompt signal, the routing center needs to acquire a plurality of second controllers which are normally not disconnected, and acquire the priority among a plurality of service requests; and the routing center reassigns the plurality of normally uninterrupted second controllers to the interrupted target network functional entity according to the priorities of the plurality of service requests.
Specifically, in some embodiments of the present application, there may be a plurality of network function entities, and a plurality of controllers; when the routing center receives a prompt signal prompting to redistribute, the redistribution between the network functional entity and the controller needs to be carried out according to the prompt signal. As shown in fig. 5, a flow diagram of an embodiment of performing reallocation provided in the embodiment of the present application is shown, where the reallocation performed by the routing center may include:
51. the routing center obtains the priorities of the plurality of service requests.
52. And reallocating the controllers and the network functional entities according to the priority.
In an actual network service system, each network functional entity can continuously generate new service requests, namely, a plurality of service requests are generated; the service corresponding to each service request is different. Among a plurality of different service requests, there may be a priority of the service request; i.e. the importance or urgency of different service requests differs. Thus, in embodiments of the present application, when the actual allocation controller re-establishes a connection with a disconnected network function entity, the re-allocation may be performed according to the priorities of a plurality of service requests.
Specifically, the routing center may obtain a plurality of service requests sent by the disconnected network function entity, and perform priority determination on the plurality of service requests. For the service request with higher priority, the controller for processing the service request is preferentially distributed to the disconnected network function entity; and for the service request with lower priority, after the controller of the service request with higher priority is redistributed, the redistribution controller gives the service request with lower priority.
In the embodiment of the application, a plurality of controllers may form a controller cluster, and the types of services processed by the controllers in the same controller cluster may be the same; the controller cluster can be multiple to process different types of service requests; while the same type of service request may include a plurality of different sub-types of service requests, a plurality of controllers within the same controller cluster may respectively handle a plurality of different sub-types of service requests.
As shown in fig. 6, a schematic flow chart of another embodiment of the path reallocation method provided in the embodiment of the present application is shown, where the path reallocation method may include:
61. a first controller cluster associated with a second network function entity is determined.
62. The network unit judges whether the second network functional entity is disconnected with the first controller cluster.
63. And if the line is disconnected, the second network functional entity generates a prompt signal and sends the prompt signal to the routing center.
64. And after receiving the prompt signal, the routing center acquires the priorities of the plurality of service requests.
65. And selecting a second controller cluster from the plurality of controllers according to the priority, and reallocating the second controller cluster to establish connection with the second network function entity.
Specifically, because a plurality of controllers can form a controller cluster, the same controller cluster usually processes only one service request of one service type, and a plurality of service requests of the second network function entity correspond to a plurality of controller clusters; there is therefore also a need to determine a first controller cluster associated with a second network functional entity; one or more first controller clusters may be provided.
After determining the first controller cluster associated with the second network functional entity, it is necessary to determine whether the second network functional entity is disconnected from the first controller cluster; specifically, the network unit may be used to determine whether the second network function entity and the first controller cluster are disconnected. In the embodiments of the present application, the network element may be at least one listener, or a plurality of network function entities; the process of determining whether the second network function entity is disconnected from the first controller cluster by using at least one listener or a plurality of network function entities may refer to the step of determining whether the first network function entity is disconnected from the first target controller by using at least one listener or a plurality of network function entities, which is not limited herein.
In the foregoing embodiment, if the second network function entity is disconnected from the first controller cluster, the second network function entity may generate a prompt signal and send the prompt signal to the routing center, so as to prompt the routing center that the second network function entity is disconnected from the first controller cluster. And after receiving the prompt signal, the routing center determines that the second network function entity is disconnected from the first controller cluster, and then the routing center may receive the plurality of service requests from the second network function entity and perform priority ordering on the plurality of service requests to determine priorities of the plurality of service requests.
In some embodiments of the present application, the importance levels or the urgency levels of the service requests may be ranked to determine the priority of the service requests. The routing center can select a second controller cluster which is not disconnected from the plurality of controller clusters except the first controller cluster according to the priorities of the plurality of service requests, and redistribute the second controller cluster to establish connection with the second network function entity.
Specifically, since the second network function entity is disconnected from the first controller cluster, the second controller cluster needs to be selected from the other controller clusters except the first controller cluster according to the actual service request. And according to the priorities of the plurality of service requests, the selected second controller cluster needs to be capable of processing the corresponding service request.
In other embodiments of the present application, the priorities of the multiple service requests may also be determined by the first or second network function entity, that is, the first or second network function entity determines the priorities of its multiple service requests, and then sends the determined priorities to the routing center. The routing center can search a corresponding controller or controller cluster according to the priorities of the service requests; no routing center is required to prioritize the plurality of service requests.
In other embodiments of the present application, the path reallocation method provided by the present application may further include:
if the first network functional entity is disconnected with the first controller, the failure rate of the first network functional entity is counted; and updating the priorities of the plurality of service requests according to the failure rate.
Specifically, when the first network function entity and the first controller are disconnected, the service request currently being processed by the first network function entity may be determined, so as to determine which service requests are easily disconnected when the first network function entity processes, and further determine different failure rates of the first network function entity under different service requests.
Since the failure rates of the first network function entity under different service requests are different, the priority of the service request can be updated according to the failure rates of the different service requests. Specifically, if the priority of the service request a is first, the service request a needs to be processed preferentially; however, since the number of the service requests a is also relatively large, the failure rate of the service request a is also high and is also the first. Therefore, when actually processing the service request a, the priority of the service request a needs to be updated to the second in consideration of not only the importance of the service request a but also the failure rate of the service request a.
In the above embodiment, after the priority of the service request is updated according to the failure rate of the service request, configuration information of multiple controllers needs to be acquired to confirm the service request that can be processed by the controller.
