In this embodiment, a method for sending a data packet is provided, including but not limited to being applied to a computer terminal, and fig. 2 is a flowchart of an alternative method for sending a data packet according to an embodiment of the present application, where the flowchart includes the following steps:
step S202: under the condition that a data packet sent by cloud equipment is received, determining an equipment identifier carried by the data packet, and inquiring a state index corresponding to the equipment identifier in an equipment state table;
step S204: and transmitting the data packet to the target device by using the configured target protocol pointer in the state index under the condition that the state information in the state index indicates that the target device corresponding to the device identifier is an available device.
Through the steps, under the condition that a data packet sent by cloud equipment is received, an equipment identifier carried by the data packet is determined, and a state index corresponding to the equipment identifier is queried in an equipment state table; transmitting the data packet to the target device by using a configured target protocol pointer in the state index under the condition that the state information in the state index indicates that the target device corresponding to the device identifier is an available device; by adopting the technical scheme, the problem that the forwarding time is long because the device information table is queried again under the condition that the routing table is traversed in the process of forwarding the data to the target device by the current cloud is solved.
In an exemplary embodiment, before querying the device state table for the state index corresponding to the device identifier, the method further includes: determining a number of available devices present in the device state table; stopping sending the data packet and executing deleting operation on the data packet under the condition that the number is smaller than a preset value; under the condition that the number is equal to a preset value, determining whether the equipment identifier carried by the data packet is the same as the target equipment identifier corresponding to the available equipment; and under the condition that the number is larger than a preset value, determining to execute a query operation in the equipment state table.
That is, before determining the state corresponding to the device, the number of currently available devices may be determined first, and if the number of available devices is smaller than the preset value, which indicates that the currently available devices are not enough to receive the data packet, the current data packet sending operation is stopped directly, and the data packet is deleted. And under the condition that the number of the available devices is equal to a preset value, the current available devices just meet the requirement of receiving the data packet, and only the fact that whether the device identifier carried by the data packet is identical to the target device identifier corresponding to the available devices is determined. If the equipment identifier carried by the data packet is the same as the target equipment identifier corresponding to the available equipment, the data packet can be directly sent to the target equipment. If the number of available devices is greater than the preset value, it is indicated that the current available devices exceed the requirement of receiving the data packet, and then a query operation needs to be performed in the device state table, so as to further determine the target device specifically receiving the data packet.
In an alternative embodiment, if the preset value is 1, then in the case where the number of available devices is 0, it is indicated that no device can accept the data packet currently. The current packet transmission operation can be directly stopped and the packet can be deleted. In the case where the number of available devices is equal to 1, it is only necessary to determine whether the device identifications in the device identification data packet of the available devices are identical. And under the condition that the number of the available devices is larger than 1, the fact that a plurality of devices can accept the data packet is indicated, and then a query operation is executed from the device state table to query the available devices for target devices consistent with the device identification in the data packet.
In an exemplary embodiment, determining whether the carried device identifier is the same as a target device identifier corresponding to the available device includes: determining a first character corresponding to the equipment identifier and determining a second character corresponding to the target equipment; calculating the similarity of the first character and the second character; under the condition that the similarity is larger than a preset similarity, determining that the equipment identifier is the same as the target equipment identifier, and allowing the data packet to be directly transmitted to the available equipment; and under the condition that the similarity is smaller than or equal to the preset similarity, determining that the equipment identifier is different from the target equipment identifier, stopping sending the data packet, and executing deleting operation on the data packet.
That is, in order to determine whether the device identifier carried by the data packet is the same as the target device identifier corresponding to the available device, the device identifier and the target device identifier may be determined to be the same according to the similarity between the first character and the second character by comparing the first character corresponding to the device identifier and the second character corresponding to the target device. If the similarity of the first character and the second character is greater than the preset similarity, the description may send the data packet to the available device. If the similarity between the first character and the second character is smaller than the preset similarity, the data packet cannot be sent to the available equipment, and the data packet can be deleted directly.
In an alternative embodiment, the device identifier carried by the data packet is 00001, the target device identifier is 00001, the similarity between the device identifier and the target device is 100%, and in the case that the preset similarity is 99%, the description is used for sending the data packet to the available device. If the device identifier carried by the data packet is 00001 and the target device identifier is 00002, the similarity of the device identifier and the target device identifier is 80%, that is, the similarity is smaller than the preset similarity, which indicates that the data packet cannot be sent to the available device and the data packet can be deleted directly.
In an exemplary embodiment, transmitting the data packet to the target device using the configured target protocol pointer in the state index includes: accessing protocol information in a routing table using the target protocol pointer; determining a transmitting mode of the data corresponding to the data packet according to the protocol information, and transmitting the data packet to the target equipment according to the transmitting mode.
That is, the corresponding transport protocol is determined from the routing table based on the protocol pointer.
In an exemplary embodiment, the method further comprises: acquiring a preset updating period of the equipment state table; collecting first state information of each device in the device state table according to the updating period, and determining a corresponding relation between the first state information and the device identifier; and updating the historical state information of each device in the device state table according to the first state information and the corresponding relation.
That is, the actual state of each device is collected according to the update period of the device state table, so that the state information in the device state table can show the actual state of each device.
In an exemplary embodiment, after transmitting the data packet to the target device using the configured target protocol pointer in the state index, the method further comprises: determining whether first feedback information sent by the target equipment is received within a preset time period; under the condition that the first feedback information of the target equipment is received, determining that the data packet is successfully transmitted; and sending the first feedback information to a cloud device to instruct the cloud device to allow the target device to continue sending other data packets.
That is, after the data packet is transmitted to the target device according to the protocol pointer, it is further required to determine whether the data packet is successfully transmitted, and further, whether it is possible to continue to transmit other data packets to the target device. If the feedback information sent by the target equipment is received, the success of the data packet sending is indicated, and other data packets can be continuously sent to the target equipment.
In an exemplary embodiment, the method further comprises: under the condition that the first feedback information of the target equipment is not received, determining that the transmission of the data packet fails; and sending second feedback information to the cloud device to instruct the cloud device to stop sending other data packets to the target device continuously.
That is, if feedback information sent by the target device is not received, it is indicated that the data packet transmission has failed. Then, feedback information preventing the cloud device from continuously sending other data packets needs to be sent to the cloud device.
It will be apparent that the embodiments described above are only some, but not all, of the embodiments of the present application. In order to better understand the foregoing method for transmitting the data packet, the following description will explain the foregoing process with reference to the embodiments, but is not intended to limit the technical solution of the embodiments of the present application, specifically:
fig. 3 is a schematic technical basis diagram of an alternative method for sending a data packet according to an embodiment of the present application, as shown in fig. 3, with the following steps:

Fig. 6 is a flowchart of an alternative prior art method for receiving a data packet according to an embodiment of the present application, specifically as follows:
after receiving the data packet from the cloud service, analyzing the transmission protocol, checking the routing table to obtain the target device id of the packet, checking the device state table to obtain the information such as the current device connection port, the device state and the bus address, determining the forwarding channel, and starting the forwarding flow.
Fig. 7 is a schematic technical principle diagram of an alternative data packet transmission method according to an embodiment of the present application, as shown in fig. 7:
an entry is added for each device in the device state table, the contents of which are references to the device transport protocol and port. With this, the forwarding protocol and port can be directly obtained by the reference without consulting the routing table, and downstream data forwarding can be started.
An index of available devices (devices in an initialized, ready, operational state) is built in a device state table, and updated in real-time as any device state changes. Through this index, a list of currently available devices can be obtained without entering any device id. When the list is empty, it indicates that no devices are currently available.
After receiving the downlink data message, the available device index table is accessed first, and when no available device exists, the downlink data message is directly discarded. When the available equipment index table has only one equipment, directly comparing the equipment id with the target equipment id in the message data, and if the equipment id is not matched with the target equipment id, directly discarding the data message; if so, the message is directly forwarded to the device.
When the available equipment index table is formed by a plurality of available equipment, after receiving a data message, the original flow of firstly checking the routing table and then checking the equipment table is changed into the flow of directly checking the equipment state table through the equipment id, if the equipment exists and is normal, the routing information in the routing table is directly abandoned through the protocol stack pointer added on the inner surface of the equipment information table, and the process of checking the routing table is omitted.
Fig. 8 is a schematic diagram of an alternative method for sending a data packet according to an embodiment of the present application, as shown in fig. 8:

In the downlink data forwarding logic in the internet of things (internet of Things, simply referred to as IOT) module, after receiving the downlink data message, the message may not be parsed temporarily, the device state is queried first, and forwarding information may be found only through the device information table under part of the scenarios, so as to realize blind forwarding. And adding a reference to the routing information in the equipment information table, directly finding the protocol information required by forwarding through the reference after determining the forwarding port, directly starting data message encapsulation and forwarding, and reducing the table look-up times.
