There are two main load methods in related technologies. One is to statically specify the AC instance corresponding to each AP. The disadvantage is that manual access is required and load balancing during operation cannot be achieved.

[0054] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] Reference Figure 1 As shown, a flow chart of the steps of a load balancing method in an embodiment of the present invention is shown. The load balancing method is applied to a server, which may be an FTTR server, or a server having the same or similar functions as the FTTR server. A management rights allocation process and multiple instance AC processes are deployed on the server, and the multiple instance AC processes form an AC group. Figure 1 As shown, the load balancing method may specifically include the following steps:

[0056] Step S11: broadcasting the registration notification of the AP to the multiple AC processes.

[0057] According to the configuration file, the AP can learn the IP (Internet Protocol) and Port (port number) of the server, and then send a registration request to the server. According to the registration request, the server broadcasts the registration notification of the AP to multiple instance AC processes, so that the AP can establish a connection with an instance AC process in the server.

[0058] Step S12: The multiple instance AC processes each determine whether their own load meets the receiving condition of the registration notification.

[0059] After receiving the registration notification of the AP broadcast by the server, each instance AC process determines whether its own load meets the receiving condition of the registration notification. The receiving condition can be set according to actual needs. For example, it can be to determine whether its own load is still idle or whether its own load exceeds a fixed value.

[0060] Optionally, in addition to determining whether its own load meets the conditions for receiving registration notifications, each instance AC process may also determine whether one or more factors such as the AP models it supports, its own performance parameters, and the maximum number of APs that can be received meet the conditions for receiving registration notifications.

[0061] In this way, the instance AC process that meets the receiving condition of the registration notification and thus sends the request for obtaining the management right of the AP can be an instance AC process that is more compatible with the AP in multiple aspects.

[0062] Step S13: The instance AC process whose own load meets the reception condition of the registration notification sends a request for obtaining the management right of the AP to the management right allocation process.

[0063] An instance AC process whose own load does not meet the conditions for receiving the registration notification, or an instance AC process whose own load and one or more factors do not meet the conditions for receiving the registration notification, ignores the registration notification.

[0064] An instance AC process whose own load meets the receiving condition of the registration notification, or an instance AC process whose own load and one or more factors meet the receiving condition of the registration notification, sends a management right acquisition request of the AP to the management right allocation process.

[0065] Step S14: the management right allocation process allocates the management right of the AP to an instance AC process that sends the management right acquisition request.

[0066] The management right of an AP is unique and can only belong to one instance AC process. The management right allocation process allocates the management right of the AP to one of the instance AC processes that sends the management right acquisition request.

[0067] Optionally, when management rights are allocated to an instance AC process, the management rights allocation process will broadcast a notification that management rights have been allocated to all instance AC processes. The instance AC process whose own load meets the receiving conditions for registration notification, or the instance AC process whose own load and one or more factors meet the receiving conditions for registration notification, will stop sending management rights acquisition requests for the AP after hearing the notification that management rights have been allocated.

[0068] In this way, other instance AC processes that are bound to be unable to obtain the management right can be prevented from continuing to send management right acquisition requests, thereby saving computing resources.

[0069] Optionally, the management right allocation process does not know the load of each instance AC process, and when allocating management rights, it allocates management rights to the instance AC process that first sends the management right acquisition request. The management right allocation process will first receive the management right acquisition request that is sent first.

[0070] Because the instance AC process with a higher load sends a management rights acquisition request more slowly, the instance AC process that meets the registration notification receiving conditions and has the lowest load will send a management rights acquisition request first, and the management rights allocation process will allocate management rights to the instance AC process with the lowest load.

[0071] In this way, there is no need to share load information between instances AC, and the management right allocation process does not need to know the load information of instance AC processes. It is possible to allocate management rights to instance AC processes that meet the receiving conditions for registration notifications and have the lowest load.

[0072] Optionally, based on the above technical solution, in order to further ensure that the management rights are allocated to the instance AC process that meets the conditions and has the lowest or lower load, the instance AC process whose load is higher than the load threshold can be set to send the management rights acquisition request after a fixed delay. The load threshold can be set according to actual needs.

[0073] An instance AC process whose own load meets the receiving conditions of the registration notification and whose own load is higher than the load threshold sends the management right acquisition request after a fixed time delay after listening to the registration notification; an instance AC process whose own load meets the receiving conditions of the registration notification and whose own load is not higher than the load threshold sends the management right acquisition request immediately after listening to the registration notification.

[0074] For example, the load threshold is 50%, the conditions for receiving the registration notification include that the load does not exceed 80%, the fixed time is 1 second, and the instance AC process-1 is a process whose other factors meet the conditions for receiving the registration notification and whose load is 40%, and the instance AC process-2 is a process whose other factors meet the conditions for receiving the registration notification and whose load is 70%. Although both the instance AC process-1 and the instance AC process-2 will send a request for obtaining management rights, the instance AC process-1 will send the request for obtaining management rights immediately after listening to the registration notification, and the instance AC process-2 will send the request for obtaining management rights after listening to the registration notification with a delay of 1 second.

[0075] In this way, it can be ensured that the management right is allocated to the AC process of the instance that meets the conditions and has the lowest or lower load.

[0076] Step S15: The AC process of the instance that obtains the management right establishes a connection with the AP.

[0077] The instance AC process that obtains the management right of the AP can establish a connection with the AP, thereby implementing the management of the AP by the instance AC.

[0078] Optionally, the AC process of the instance that has obtained the management right establishes a connection with the AP through the following steps: the AC process of the instance that has obtained the management right notifies the AP of its own address (IP) and port number (Port); after receiving the address and port number of the AC process of the instance, the AP sends information according to the address and port number, and the AC process of the instance that has obtained the management right establishes a connection with the AP according to the information returned by the AP after receiving the address and port number. In this way, the connection between the AC process of the instance that has obtained the management right and the AP can be established.

[0079] Optionally, the instance AC process may also establish a connection with the AP in other ways. For example, the server obtains information about the AP and connects the AP with the instance AC process.

[0080] By adopting the technical solution of the embodiment of the present application, upon receiving the registration notification of the AP, each instance AC can determine whether to send the management right acquisition request of the AP to the management right allocation process according to its own load, and the management right allocation process allocates the management right to an instance AC process that sends the management right acquisition request, so that the instance AC and the AP are connected. Among them, there is no need to share load information between multiple instance ACs, and the management right allocation process does not need to know the load information of the instance AC, and the allocation of management rights can be completed, thereby achieving load balancing between instance ACs.

[0081] In addition, by adopting the technical solution of the embodiment of the present application, dynamic adjustment of the load can be achieved. Instead of directly determining the instance AC process corresponding to each AP, when each AP is connected, its management rights can be dynamically allocated to the instance AC process that meets the conditions and has the lowest or lower load.

[0082] Therefore, the technical solution of the embodiment of the present application has the advantages of no need for human intervention in the entire process, no need for communication between instance ACs, high efficiency, and low resource occupancy. It solves the problems in related technologies that require human intervention, low efficiency and high maintenance costs, and cannot dynamically adjust the load, resulting in internal resource consumption.

[0083] Figure 2 A schematic diagram of the competition for management rights among instance AC processes in the related art is shown, wherein the instance AC process corresponding to each AP is determined by static designation. This method requires manual intervention and cannot achieve load balancing during operation.

[0084] Figure 3 A schematic diagram of the competition for management rights of instance AC processes in the related art is shown, wherein multiple instance AC processes periodically share load information. After sharing the load information, instance AC process-1 with a lower load establishes a connection with the AP after learning that its load is lower. The disadvantage of this method is that the instance ACs need to communicate periodically, which occupies resources.

[0085] Figure 4 A schematic diagram of the instance AC process competing for management rights in an embodiment of the present application is shown, wherein load information is not shared between multiple instance AC processes. The AP sends a registration notification to the server, and the server broadcasts the registration notification to multiple instance AC processes, and each instance AC process determines whether it meets the receiving conditions of the registration notification. The instance AC process that meets the conditions sends a management rights acquisition request to the management rights allocation process. The management rights allocation process allocates management rights to the instance AC process that first sends the management rights acquisition request, so that a connection is established between the instance AC process and the AP. In this way, the management rights can be simply and quickly allocated to the instance AC process that meets the conditions and has the lowest load.

[0086] Optionally, based on the above technical solution, if the AP connected to the server is to be migrated to other servers, the address and port number of the server in the configuration file of the AP can be modified to the address and port number of the other server, and the AP will send a registration notification to the other server according to the address and port number of the other server in the configuration file, thereby establishing a connection with the instance AC process included in the other server. Among them, the other server is also deployed with a management right allocation process and multiple instance AC processes. After sending a registration notification to other servers, the other server will also broadcast the registration notification to multiple instance AC processes deployed by itself. The multiple instance ACs each determine whether their own load meets the receiving conditions of the registration notification. The instance AC process whose own load meets the receiving conditions of the registration notification sends a management right acquisition request of the AP to the management right allocation process; the management right allocation process allocates the management right of the AP to the instance AC process that first sends the management right acquisition request, so that the instance AC process establishes a connection with the AP.

[0087] When migrating an AP to another server, it is necessary to disconnect the AP from the instance AC process of the original server. When the AP is disconnected from the instance AC process, it is not necessary to notify other instance AC processes.

[0088] Optionally, based on the above technical solution, the management rights allocation process can be a redis process (a key-value storage system). When notifying each instance AC process AP of a registration request, it brings the competing key. An instance AC successfully executes setnx (lock) on the competing key in redis, and the value (value) records the information of the instance AC process that successfully competes (obtains management rights). When other instances AC execute setnx on the competing key, they will return failure because the key already exists, that is, the competition fails.
