Detailed Description
In order to solve the problem that a method for selecting a resource directory based on a deviation factor is inaccurate in the prior art, the invention provides a method for selecting a resource directory RD. The present invention will be described in further detail below with reference to the drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
A first embodiment of the present invention provides a method for selecting a resource directory RD, which is applied to a server, that is, a server device having resources, and referring to fig. 1, the method includes:
step S101, judging whether the mobile terminal is networked or not, if not, entering step S102, and if so, entering step S103;
step S102, performing weighted calculation through a preset weight parameter according to a local resource directory, and determining a resource directory of a release resource according to a weighted calculation result;
step S103, sending a request for determining a resource catalog of the release resource to the cloud platform, and receiving the resource catalog of the release resource determined by the cloud platform.
That is to say, in the embodiment of the present invention, the server performs weighted calculation on the resource directory according to the preset weight parameter to determine the resource directory of the published resource, or determines the resource directory of the published resource by performing weighted calculation on the resource directory according to the preset weight parameter through the networked receiving cloud platform, so that the resource directory is accurately selected, and the problem that the method for selecting the resource directory based on the deviation factor in the prior art is inaccurate is effectively solved.
On the other hand, the embodiment of the invention automatically performs weighting calculation on the resource directory according to the preset weight parameter, so that the method and the device can effectively improve the efficiency of determining the resource directory. Therefore, the problem that in the prior art, when a large number of devices exist, the processing efficiency of the whole system is low due to the fact that the weighting coefficients are manually configured by a user is effectively solved.
Generally speaking, the core of the embodiment of the invention is that in the networking condition, when the server can interact with the cloud platform, the resource catalog is selected by default in a cloud platform mode, so that the working complexity of the server can be reduced, and when the server is not networked, the weight parameters are selected locally in the server so as to select the resource catalog.
In the embodiment of the invention, under the condition that the server is not networked, the server automatically sets the preset weight parameter according to a preset rule, or sets the preset weight parameter according to a use environment.
In practical implementation, the preset rule of the present invention may be a default recommended weight parameter, for example, the weight parameter of the power source is set to be 25%, the weight parameter of the mobility is set to be 10%, the weight parameter of the network is set to be 30%, the weight parameter of the memory is set to be 25%, the weight parameter of the load factor currently requested by the resource directory is set to be 10%, and the like. Or may be a series of recommended weight parameters set for different situations.
The default recommended weight parameter may be set by the user when the server is configured, or may be set by the user at the time of factory shipment of the device, and the user may select and use a certain recommended weight parameter as needed.
The setting of the weight parameters according to the environment in the embodiment of the present invention means that a user can customize some modes according to the use environment of the device and set default weight parameters for the modes. For example, if a device is used in a factory, the factory mode may be set, and the weight parameter occupied by the power supply may be reduced, so that all the devices set to the factory mode perform calculation using the set weight parameter, and the resource directory to be finally used is selected.
The actual implementation of these two weighting factor selections is determined by an attribute named local _ wei _ choose, which has two values 0 and 1, where 0 represents the automatic setting of the weighting parameter and 1 represents the setting of the weighting parameter according to the environment. The server selects a corresponding weight parameter calculation method by setting the attribute value.
That is, in the implementation, a person skilled in the art can set a series of setting modes of the weight parameters according to different environments and various application scenarios, so as to facilitate the user to select and use the setting modes.
Because the invention defines the determination mode of the weight parameter, the resource catalogue can be accurately selected based on the deviation factor, and the problem of unclear calculation method of the deviation factor is effectively avoided.
In a specific implementation, in the embodiment of the present invention, the resource directory of the release resource determined by the cloud platform is received, and the resource directory of the release resource determined by the cloud platform through weighting calculation according to the preset weight parameter is received.
Specifically, the cloud platform according to the embodiment of the present invention obtains a resource directory that meets the server requirements based on a request of the server, and sends the resource directory to the server.
Moreover, the server in the embodiment of the present invention receives the device identifier ID of the device of the resource directory sent by the cloud platform, and issues the resource on the device.
Fig. 2 is a schematic flowchart of another method for selecting a resource directory RD according to a first embodiment of the present invention, and fig. 3 is a schematic flowchart of another method for selecting a resource directory RD according to a first embodiment of the present invention, as shown in fig. 2 and 3, including:
the server issues a multicast request aiming at the '/oic/rd' resource in the local area network;
the equipment which exposes the "/oic/rd" resource, namely the equipment which can be used as a resource directory responds to the request of the server and returns the relevant parameters to the server in response;
after receiving the response, the server performs weighted calculation on each parameter in the response according to the recommended default weight setting or the environment weight setting;
and the server issues own resources to the equipment corresponding to the larger one in the calculation results, and the resource issuing is completed.
Fig. 4 is a flowchart illustrating a method for selecting a resource directory RD according to a first embodiment of the present invention, as shown in fig. 4, including:
in practice, the server may directly select locally when selecting the resource directory, or may select through the cloud platform. When the server is networked and can interact with the cloud platform, the resource catalog is selected by default in a cloud platform mode, so that the working complexity of the server can be reduced; when the server is not networked, the resource directory can be selected only by locally selecting the weighting coefficient, and the overall process of selecting the resource directory in the embodiment of the invention comprises the following steps:
when the server is not networked, the server cannot interact with the cloud platform:
the server issues a multicast request aiming at the/o i c/rd resource in the local area network;
the equipment which exposes the "/o i c/rd" resource, namely the equipment which can be used as a resource directory responds to the request of the server and returns the relevant parameters to the server in response;
after receiving the response, the server performs weighted calculation on each parameter in the response according to the recommended default weight setting or the environment weight setting;
and the server issues own resources to the equipment corresponding to the larger one in the calculation results, and the resource issuing is completed.
When the server is networked and can interact with the cloud platform, the overall process of selecting the resource catalog in the embodiment of the invention comprises the following steps:
the server sends a request for selecting the resource catalog to the cloud platform;
the cloud platform finds out equipment which can be used as a resource directory in the local area network according to whether the registered equipment contains the "/o i c/rd" resource or not, and obtains relevant parameters of the equipment;
the cloud platform selects one of two weight setting strategies and performs weighted calculation on the related parameters;
the cloud platform returns the device i d of the device with the larger calculation result as a response to the server;
after receiving the response, the server issues its resource to the device corresponding to the device i d, and completes the selection of the resource directory.
A second embodiment of the present invention provides a method for selecting a resource directory RD, which is applied to a cloud platform, and referring to fig. 5, the method includes:
s501, receiving a request for determining a resource directory of a release resource sent by a server;
s502, according to the pre-stored resource catalog, carrying out weighted calculation through preset weight parameters, determining the resource catalog of the issued resource according to the weighted calculation result, and sending the resource catalog to the server.
According to the embodiment of the invention, the cloud platform is used for selecting the resource catalog, so that the working complexity of the server is reduced, and the cloud platform is used for determining the resource catalog of the release resource by performing weighted calculation on the resource catalog according to the preset weight parameter, so that the resource catalog can be accurately selected, and the problem that the method for selecting the resource catalog based on the deviation factor in the prior art is inaccurate is effectively solved.
The method of the embodiment of the invention also comprises the following steps: and registering and storing the resource directory transmitted by the equipment.
Note that the device is a device that serves as a resource directory.
That is to say, to implement the resource directory selection through the cloud, the resource directory needs to be connected with the cloud first, and the relevant attribute parameters of the resource directory need to be issued to the cloud platform, so as to implement the registration of the cloud platform. Since each device has a unique Identifier (ID) and a MAC address, the cloud platform can obtain the relevant information of the device by looking up the device ID or the MAC address.
The equipment which can be used as a resource directory needs to expose '/oic/rd' resources, and by searching the resources, the cloud platform can know which equipment in a certain local area network can be used as the resource directory, and simultaneously acquire the IDs of the equipment, so that the relevant parameters of the resource directory can be acquired.
In the embodiment of the present invention, performing weighted calculation according to a pre-stored resource directory by using a preset weight parameter, and determining a resource directory with a larger weighted calculation result as a resource directory for publishing resources includes: and acquiring a resource directory which is in the same local area network with the server according to the registered resource directory, performing weighting calculation through a preset weighting parameter, and determining the resource directory with a larger weighting calculation result as the resource directory of the release resource.
Since the relevant parameters of the resource directory are constantly changing, such as the memory, the resource directory needs to periodically update the parameter information to the cloud. The cloud platform receives a periodic updating result of the resource directory sent by the equipment, and updates the stored resource directory according to the periodic updating result of the resource directory.
If one server side wants to realize the selection of the resource catalog through the cloud platform, a request for selecting the resource catalog is sent to the cloud platform, the cloud platform can find the equipment which is positioned under the same local area network as the server side and can be used as the resource catalog through the IP address of the server, then the cloud platform can obtain the relevant parameter information of the equipment for weighting, and the selection of the weighting coefficient is consistent with the local selection method. After the weighting calculation is finished, the cloud platform compares the weighting calculation results of the resource directories, selects the resource directory with a larger result, and returns the device id of the resource directory to the server as a response. After receiving the response, the server discovers the corresponding resource directory by using an endpoint discovery mode in the OCF, and issues the resource to the resource directory, so that the selection of the resource directory is completed.
In the embodiment of the present invention, the cloud platform may automatically set the preset weight parameter according to a preset rule, or set the preset weight parameter according to a use environment.
In practical implementation, the preset rule of the present invention may be a default recommended weight parameter, for example, the weight parameter of the power source is set to be 25%, the weight parameter of the mobility is set to be 10%, the weight parameter of the network is set to be 30%, the weight parameter of the memory is set to be 25%, the weight parameter of the load factor currently requested by the resource directory is set to be 10%, and the like.
It should be noted that the default recommended weight parameter may be set by the user when configuring the server.
Setting the weight parameters according to the environment means that a user can customize some modes according to the use environment of the equipment and set default weight parameters for the modes. For example, as described above, if a device is used in a factory, the factory mode may be set, and the weight parameter occupied by the power supply may be reduced, so that all the devices set to the factory mode perform calculation using the set weight parameter, and the resource directory to be finally used is selected.
The actual implementation of these two weighting factor selections is determined by an attribute named local _ wei _ choose, which has two values 0 and 1, 0 representing the automatic setting of the weighting parameters and 1 representing the setting of the weighting parameters according to the environment. The server selects a corresponding weight parameter calculation method by setting the attribute value.
Of course, in the implementation, a person skilled in the art may set a series of setting modes of the weight parameter according to different environments and various application scenarios, so as to facilitate the user to select and use the setting modes.
Fig. 6 is a flowchart illustrating a method for selecting a resource directory RD according to a second embodiment of the present invention, as shown in fig. 6, the method includes:
the server registers and stores the resource directory sent by the equipment;
the server sends a request for selecting the resource directory to the cloud platform;
the cloud platform finds out equipment which can be used as a resource directory in the local area network according to whether the registered equipment contains "/oic/rd" resources, and obtains relevant parameters of the equipment;
the cloud platform selects one of two weight setting strategies and performs weighted calculation on the related parameters;
the cloud platform returns the device id of the device with the larger calculation result to the server as a response;
and the server releases own resources to the equipment corresponding to the equipment id after receiving the response, and completes the selection of the resource directory.
