Detailed Description
The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.
It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 3 to 4, an embodiment of the present application provides a method for connecting networking devices of an intelligent networking platform, including: the method comprises the steps that networking equipment is verified, the networking equipment comprises a gateway, an AP, an AC and the like, the networking equipment is firstly connected with an intelligent networking platform, and the intelligent networking platform verifies the networking equipment; the method comprises the steps that a main management server and a standby management server are allocated to networking equipment which passes verification, the networking equipment comprises IP addresses and ports of the main management server and the standby management server, the networking equipment tries to connect the main server at first, if the main management server is in a normal state, networking equipment connection and on-line are completed, if the main management server is in an abnormal state, the standby management server tries to connect, if the standby management server is in a normal state, connection is completed, and if the standby management server cannot be connected, the main management server and the standby management server are reallocated. Therefore, the method and the device can avoid the situation that after the single-point long connection of the networking equipment fails, the networking equipment needs to log in the platform again to perform complicated and time-consuming request, management server acquisition, verification, authentication and the like, can reduce the offline reconnection time of the networking equipment, and improve the connection reliability of the networking equipment.
In other embodiments, further comprising: the method comprises the steps of periodically polling networking equipment, checking whether the networking equipment is normally paid and online, if the networking equipment is connected with a main management server before, and if the networking equipment cannot be connected with the main management server within preset polling times, trying to connect a standby server, wherein the preset polling times are five times.
In other embodiments, further comprising: and periodically polling the networking equipment, checking whether the networking equipment is normal wage and whether the networking equipment is online, if the networking equipment is connected with a standby management server before, and if the networking equipment cannot be connected with the standby management server within preset polling times, redistributing the main management server and the standby management server, wherein the preset polling times are five times for example.
In other embodiments, a management server cluster is deployed on a cloud host, and a method for allocating a primary management server and a backup management server from the management server cluster includes: acquiring the connection number of each management server; selecting a main management server by using a weighted polling algorithm; and randomly selecting the management server which does not reach the maximum connection number as a standby management server. The networking equipment management server cluster is an elastic cloud host provided by a rented cloud provider, and dynamically joins the equipment management server according to the number of the accessed networking equipment, so that the dynamic expansion of the networking management cluster is realized. Therefore, the management server has the characteristics of different configurations, distribution on different hosts and the like. Aiming at the characteristics of the management server, a cloud server inverse affinity and weighted load balancing algorithm is provided to allocate a 'main + standby' management server for the networking equipment, as shown in fig. 4. The anti-affinity of the cloud host, namely the two selected 'main + standby' management servers do not run on the same host, so that the phenomenon that the main and standby servers fail simultaneously due to the failure of a physical host is avoided. Second, different device connection servers may not have the same machine configuration and current system load, and therefore may not have the same pressure resistance. Higher weights are assigned to machines configured high and low load to enable them to handle more requests, while low and high load machines are assigned lower weights to reduce their system load, weighted polling handles this problem well and assigns requests to the back-end in order and according to weight. By means of a weighted load balancing algorithm, the connection load of the networking equipment can be balanced, the capacity of the cloud server is exerted to the maximum extent, the cloud server is added only when the existing server connection situation is close to full-load operation, and the computing capacity of the networking equipment management cluster is exerted to the maximum extent when the cost consumed by renting the cloud server is saved.
One possible pseudocode for the cloud server inverse affinity + weighted load balancing algorithm to execute is as follows:
in other embodiments, the connection capabilities of the management server are defined as: current number of connections/weight max number of connections; and selecting the management server with the minimum connection capacity value as the main management server. For the selection of the main server, a weighted load balancing algorithm is required to be used, the current configuration of the cloud host is mainly divided into three types, namely 2-core 4G, 4-core 8G and 8-core 16G, and the weight values distributed according to the experimental test results are 1,2.3,4.5 respectively. The current connection number/(weight — maximum connection number) is used to indicate the connection capability of the current cloud service, and a smaller value indicates a smaller load on the current server, and the current server is more suitable to be the master server.
In other embodiments, a manner is provided by which to determine the weight that a management server configured high and low in load weighs more than a management server configured low and high in load.
In other embodiments, a management server different from the primary management server hosts is selected as the standby server. The selection of the standby server firstly eliminates the cloud host running on one host machine with the main server, namely, the anti-affinity is realized; then, the server which has not reached the maximum connection number is randomly selected as the standby server, because the probability that the main server is off-line due to failure is small, and when the server has not reached the maximum, the connection can be performed, so that the standby server is only used for standby. And after the main server fails, switching to the standby server, namely, after the connection number of the standby server is increased, the possibility of being selected as the main server again is reduced, so that the load of each cloud server is ensured to reach the optimal state.
In other embodiments, a specific way of online verification is provided, and online verification is performed on the networking device through an ID and a PIN code.
In another embodiment, a "master + backup + reconnect" networking device connection method is provided, as shown in fig. 3, that is, when a networking device is connected for the first time, after a device passes verification, a networking platform uses a load balancing algorithm, and simultaneously considers the inverse affinity of a cloud server, as shown in fig. 4, a connected master control server IP and port and a standby control server IP and port are allocated to the networking device for the first time, and a plug-in "implanted" in the networking device can record information of the master and backup servers, and then is connected to the master control device, so as to complete access and management of the networking device.

step1: the equipment firstly accesses a networking platform, and completes online verification of the equipment through an ID and a PIN code;
step2: according to a server selection algorithm used by a networking platform, ip addresses and ports of a master server and a standby server are respectively selected for networking equipment and returned to the networking equipment;
step3: after receiving the addresses of the main server and the standby server distributed by the platform, the 'plug-in' of the networking equipment is recorded in the networking equipment and starts to make connection preparation;
step4: connecting the main server and the port; if the main server is normal, completing the connection, otherwise, trying to connect the standby server (step 7);
step5: the main service is successfully connected, and the networking equipment is completed to be on-line;
step6: the equipment is periodically checked to judge whether the equipment works normally or not and whether the equipment is on line or not. If the system is on line, the system continues to work and performs inspection in the next period; if the equipment cannot be connected with the main server after the polling, namely the equipment is judged to be disconnected for 5 continuous periods, the standby server is tried to be connected (shown in step 7);
step7: connecting a standby server and a port; if the standby server is normal, the connection is finished, otherwise, the networking platform is reconnected, and the management host is waited for distribution again (step 1 step is entered again);
step8: the standby service is successfully connected, and the networking equipment is completed to be on line;
step9: the equipment is periodically checked to judge whether the equipment works normally or not and whether the equipment is on line or not. If the system is on line, the system continues to work and performs inspection in the next period; if the equipment can not be connected with the standby server after the polling, namely the equipment is judged to be disconnected in 5 continuous periods, otherwise, the networking platform is reconnected, and the management host is waited for distribution again (step 1 step is entered again).
