The server 11 may provide various cloud services, data platform services, and the like.
The server 11 may be implemented by hardware, or the server 11 may be implemented by software.
When the server 11 is implemented using hardware, the server 11 may be implemented as a distributed server cluster of multiple servers or as a single server. As shown in FIG. 1, server 11 may be implemented as a distributed server cluster of servers 111 and 112. It should be understood that, on the basis of fig. 1, the server 11 may also be implemented as a distributed server cluster consisting of three servers or more than three servers. Server 11 may also be implemented as a single server, for example, server 11 may be implemented as server 111 or server 112 in fig. 1.
When the server 11 is implemented using software, the server 11 may be implemented as a plurality of pieces of software or software modules or as a single piece of software or software module.

The following examples explain and illustrate the present application as embodied in the server 11. In the prior art, the access server of the gateway 12 can be used for off-line detection of the gateway. The gateway 12 sends a breathing request to the access server at regular time; the access server receives the breathing request and sends a response of the breathing request to the gateway 12; if the access server receives a disconnect event (disconnect) sent by gateway 12, gateway 12 is considered to be offline. In this case, if the access server fails, offline information for the gateway 12 may be lost.
In the prior art, the gateway 12 sends a breath request to the access server at regular time, where the breath request is used to indicate that the gateway 12 is currently in a survival state, i.e. a normal working state; the access server receives the breathing request, sends a response of the breathing request to the gateway 12 and records corresponding communication time; gateway 12 may also transmit an uplink message to the access server, which receives the uplink message and also records the corresponding communication time. The access server may set a timed offline detection task to periodically query the communication time of the gateway 12; if the time interval between the last communication time of the gateway 12 and the current time is greater than the preset time interval, the gateway is considered to be possibly offline. In this case, the operation of offline detection is complicated, and it is necessary to rely on the communication time of the gateway 12 stored in the storage unit of the access server; when the gateway 12 is online, data communication is frequently performed, and communication time may change constantly, which directly causes that the write pressure of a storage unit of the access server is relatively large; the off-line detection of the gateway 12 depends on the timing polling of the timing off-line detection task, the off-line detection is not timely, and the reading pressure of the storage unit of the access server is relatively large due to frequent polling.
In order to solve the above problem, the inventor of the present application provides a scheme, when the first access server is abnormal, at least one gateway accessing the first access server may be obtained and an offline gateway may be screened from the at least one gateway, so as to implement offline detection of the gateway when the first access server is abnormal; when the first access server is normal, the offline gateway information reported by the first access server is received, so that the offline detection of the gateway can be realized by still depending on the information of a link layer (namely, the link layer of the first access server) when the first access server is normal, the dependence on an inefficient polling mechanism (namely, the gateway sends information or a request, and the first access server receives the information or the request and records corresponding communication time and regularly inquires the recorded communication time to determine whether the gateway is online) is avoided, and the offline detection efficiency of the gateway is improved.

The first access server may send its keep-alive information at preset time intervals. And if the keep-alive information sent by the first access server is received in a preset time period corresponding to the preset time interval, the first access server works normally. If the keep-alive information sent by the first access server is not received within a preset time period corresponding to the preset time interval, it indicates that the first access server is abnormal, for example, no response occurs or the first access server is restarted. It should be understood that the preset time interval and the preset time period may be set according to an actual scene, and the embodiment of the present application is not limited thereto.

Referring now to FIG. 13, shown is a schematic diagram of an implementation scenario 1300 suitable for use in implementing some embodiments of the present application.
As shown in fig. 13, the implementation scenario 1300 includes a gateway 1301 and a server 1302. Gateway 1301 and server 1302 may be implemented as the gateways and servers shown in figure 1. In FIG. 13, a server 1302 may include functionality to implement: load balancing services 1322, access services 1324, offline detection services 1326, device management services 1328, and so on. Access service 1324 may be implemented by an access server as described in any of the embodiments above. The access server may also be implemented as part of the server 1302. The load balancing service 1322, the offline detection service 1326, and the device management service 1328 may be implemented as one server (or one server farm), respectively; any two of the load balancing service 1322, offline detection service 1326, device management service 1328 may be implemented as one server (or one server farm), while the remaining one service may be implemented as one server (or one server farm); or the load balancing service 1322, offline detection service 1326, device management service 1328 may be implemented as one server (or one server farm); and so on. It should be understood that the load balancing services 1322, access services 1324, offline detection services 1326, device management services 1328 described above are partitions of the functionality of the server 1302, not in an actual physical sense.
Load balancing service 1322:
when accessing the server 1302, the gateway 1301 needs to request a load balancing service 1322; the load balancing service 1322 assigns an accessible access service address to the gateway 1301; the gateway 1301 accesses the corresponding access service 1324 according to the access service address.
When the keep-alive information of the access service 1324 is not received within the preset time period, the load balancing service 1322 regards that the access service 1324 is abnormal, at this time, on one hand, the load balancing service 1322 updates an accessible access service address list, and deletes the address of the access service 1324 from the list, so that a new gateway cannot access the access service 1324; on the other hand, access service exception information is sent to offline detection service 1326, which includes the first machine name and the first process name of access service 1324.
Offline detection service 1326:
the offline detection service 1326 receives the access service exception information from the load balancing service 1322, and acquires the gateway list corresponding to the access service, which is stored in its storage unit, according to the first machine name and the first process name in the access service exception information. Corresponding to each gateway in the gateway list, obtaining the second machine name and the second process number of each gateway, and determining the offline gateway by using the above 409, 410, and 411.
Access service 1324:
keep-alive information is periodically sent to the load balancing service 1322 to transmit its own operating parameters, machine number and process number.
Whenever a new gateway is accessed to access service 1324, access service 1324 stores in its own storage location the unique token for the new gateway in association with the first machine name and the first process number.
From the above scenario, the application divides the off-line detection of the gateway into two parts; in most cases, the access service works normally, at the moment, the offline detection depends on the offline message of a link layer, namely, the offline message is transmitted to the access service from a gateway and then transmitted to the equipment management service from the access service, and an inefficient polling mechanism is abandoned, so that the detection efficiency is improved; in special cases, for example, when the access service is not responsive or abnormal, it is necessary to traverse the gateways that have previously accessed the service, and determine the gateways that have not updated the access information as offline gateways.
