The nodes to be synchronized 101, 102 may interact with the synchronization node 104 via the network 103 to receive or send messages or the like. The nodes 101 and 102 to be synchronized may be hardware or software.

The server can analyze and process the received data such as the data processing request sent by the terminal equipment, and feed back the processing result to the terminal equipment.

It should be understood that the number of nodes to be synchronized, the network and the synchronization nodes in fig. 1 are merely illustrative. There may be any number of nodes, networks and synchronization nodes to be synchronized, as desired for the implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for synchronizing information in accordance with the present disclosure is shown. The method for synchronizing information includes the steps of:
In the present embodiment, an execution subject of the method for synchronizing information (e.g., the synchronization node 104 shown in fig. 1) may detect that information to be synchronized is detected through a wired connection manner or a wireless connection manner. It is noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a UWB (Ultra Wideband) connection, and other wireless connection means now known or developed in the future.
In the prior art, when a node synchronizes information, multiple handshaking operations are required to establish communication connection. Thereafter, whether or not synchronization information is required, it is necessary to monitor whether or not the communication connection is normal by heartbeat. Therefore, the node has more operations when synchronizing the information, and the synchronization time is increased. The nodes need heartbeat for a long time to monitor the connection state, and the data processing burden of the nodes is increased.
When the information to be synchronized which needs to be synchronized is detected, the information to be synchronized can be firstly packaged into a data packet to be synchronized. The information to be synchronized may be node configuration information, state information, user data saved on the node by the user, and the like, and may be determined specifically according to actual needs.
In some optional implementation manners of this embodiment, the encapsulating the information to be synchronized into a data packet to be synchronized may include the following steps:
and step one, inquiring the data volume of the information to be synchronized.
In the process of synchronizing information, the data size of the synchronizing information is needed, so that the information to be synchronized can be successfully synchronized to the node to be synchronized.
And secondly, in response to the fact that the data volume is larger than a set threshold value, dividing the information to be synchronized into at least one piece of sub information to be synchronized.
When the data size of the information to be synchronized is smaller than the set threshold, the information to be synchronized can be considered to be successfully synchronized to the node to be synchronized at one time, and at this time, the execution main body can directly package the information to be synchronized into a data packet to be synchronized. When the data size of the information to be synchronized is larger than the set threshold, errors are easy to occur in the synchronization layer. To this end, the execution body may divide the information to be synchronized into at least one piece of sub-information to be synchronized. Wherein, each sub-information to be synchronized needs to set a threshold.
And thirdly, packaging the sub information to be synchronized into a sub data packet to be synchronized for the sub information to be synchronized in the at least one sub information to be synchronized.
After the sub-to-be-synchronized information is obtained, the execution main body may encapsulate each piece of to-be-synchronized information into a sub-to-be-synchronized data packet.
In some optional implementation manners of this embodiment, the encapsulating the sub-to-be-synchronized information into a sub-to-be-synchronized data packet may include the following steps:
the first step, compress the sub-information to be synchronized into data compression packet, and set data packet information for the sub-information to be synchronized.
In the process of synchronizing information, information loss may occur due to various interferences, and in order to enable the node to be synchronized to know whether information loss exists in the received data packet to be synchronized, the execution main body may set data packet information for the sub information to be synchronized. The data packet information includes data packet transmission state information and data volume information of the data compression packet. And the data packet sending state information is used for representing the state information of the sent sub information to be synchronized. The status information may be any one of: normal, empty, ignore, etc. Correspondingly, the packet transmission status information may be "110", "010", "100", and the like.
The packet information may be represented by a bit data sequence. For example, the packet information may be: "1101001100110101". Wherein, the first three bits "110" may indicate that the data packet transmission status information is "normal"; the 4 th to 7 th bits "1001" may indicate that the data size information of the data compression packet is the data size corresponding to the next 9 bits (i.e., "100110101").
And step two, packaging the data compression packet and the data packet information into a sub-packet to be synchronized.
And after the data packet information is obtained, packaging the data packet information and the data compression packet together into a sub-data packet to be synchronized. When the data volume of the information to be synchronized is smaller than the set threshold, the data packet information also needs to be set, and the data packet to be synchronized is obtained at this time.
When the user data protocol transmits data, the long-time communication connection between a data transmitting party and a data receiving party is not required, and only a data packet to be synchronized needs to be transmitted to a node to be synchronized at the same time as information. In the embodiment, the data packet to be synchronized is sent through the user data protocol, so that a plurality of information interaction operations irrelevant to information synchronization in the information synchronization process can be reduced, the information synchronization process is simplified, and the information synchronization efficiency is improved.
As can be seen from the above description, the data packet to be synchronized includes data packet information. After the data packet to be synchronized is sent to the node to be synchronized, the node to be synchronized can analyze the information to be synchronized according to the data packet information in the data packet to be synchronized, and return feedback information according to the analysis result. And the execution main body completes information synchronization according to the feedback information.
Therefore, the information is transmitted through the user data protocol when the information synchronization is needed, the nodes do not need to keep communication connection for a long time through heartbeat detection, and the problems of information concurrence and the like do not need to be considered. Therefore, the data processing amount of the nodes is reduced, the information synchronization process is simplified, and the effectiveness of the information synchronization is improved.
In some optional implementation manners of this embodiment, the completing information synchronization according to the feedback information may include the following steps:
and step one, responding to the fact that the feedback information is successfully transmitted, and finishing information synchronization operation.
When the feedback information is transmitted successfully, it indicates that the node to be synchronized has received the corresponding data packet to be synchronized, and the information to be synchronized in the data packet to be synchronized is complete. At this time, the execution body may consider this time that the information synchronization has been completed.
And step two, in response to the fact that the feedback information is transmission failure, the data packet to be synchronized is retransmitted.
When the feedback information is transmission failure, it indicates that the node to be synchronized has received the corresponding data packet to be synchronized, but the information to be synchronized in the data packet to be synchronized is incomplete. Generally, the executing entity may send the data packet to be synchronized to the node to be synchronized again according to the above steps, and know that the content returned by the node to be synchronized is the feedback information of successful transmission.
With continued reference to FIG. 3, a flow 300 of one embodiment of a method for synchronizing information in accordance with the present disclosure is shown. The method for synchronizing information includes the steps of:
In this embodiment, an execution subject of the method for synchronizing information (for example, the nodes to be synchronized 101 and 102 shown in fig. 1) may receive the data packet to be synchronized sent by the synchronization node through a wired connection manner or a wireless connection manner.
The execution body can receive a data packet to be synchronized sent by the synchronization node. After receiving the data packet to be synchronized sent by the synchronization node, the execution main body may analyze the data packet to be synchronized to obtain analysis information.
In some optional implementation manners of this embodiment, the analyzing the data packet to be synchronized to obtain analysis information may include the following steps:
firstly, analyzing a data compression packet and data packet information from the data packet to be synchronized.
As can be seen from the above description, the data packet to be synchronized includes a data compression packet and data packet information. The execution body can analyze the data compression packet and the data packet information from the data packet to be synchronized. The data packet information may include data packet transmission status information and data volume information of the data compression packet.
And step two, responding to the data volume information in the data packet information being the same as the data volume of the data compression packet, determining that the information transmission is correct, decompressing from the data compression packet to obtain the information to be synchronized, and determining that the information transmission is wrong.
After obtaining the packet transmission status information and the data size information of the data compression packet, the execution main body may compare the data size information of the data compression packet and the data size of the data compression packet. And if the data volume information of the data compression packet is the same as the data volume of the data compression packet, indicating that no information is lost in the information transmission process. At this time, the execution body may set the parsing result to be correct for information transmission. Then, the execution body can decompress the data compression packet to obtain the information to be synchronized. If the data volume information of the data compression packet is different from the data volume of the data compression packet, the information loss occurs in the information synchronization process. At this time, the execution body may set the parsing result as an information transmission error. The information transmission error may include any one of: retry, empty packet, incomplete, duplicate, failure, etc. Wherein, the retry can indicate that the synchronization node needs to resend the data sent before; the null packet may indicate that the actual data sent is null; incomplete may mean incomplete reception of data sent by the synchronization node; a duplicate may indicate that duplicate data was received; failure may indicate that an exception occurs during the data reception process, and the message reception cannot be completed normally.
And 302, constructing feedback information through the analysis information, and sending the feedback information to the synchronization node.
After the analysis information is obtained, the execution main body can construct feedback information through the analysis information and send the feedback information to the synchronization node. Therefore, the communication connection between the nodes is not required to be maintained through heartbeat detection, and the problems of information concurrence and the like are not required to be considered. The data processing amount of the nodes is reduced, the information synchronization process is simplified, and the effectiveness of the information synchronization is improved.
In some optional implementation manners of this embodiment, the constructing the feedback information by using the analysis information may include the following steps:
and step one, in response to the analysis result that the information transmission is correct, the data packet sending state information is modified into first data packet receiving state information with the content of successful transmission, and first feedback information is constructed according to the first data packet receiving state information.
When the analysis result shows that the information transmission is correct, the execution main body can modify the data packet sending state information into the first data packet receiving state information with the content of successful transmission. For example, the first packet reception state information may be "000". Where "000" may indicate a successful transmission. Then, the execution body may construct first feedback information according to the first packet reception status information. The first feedback information may only include the first data packet receiving status information, or may also include the data volume information and the data compression packet of the data compression packet in the data packet sending status information, which is specifically determined according to the actual needs.
And a second step of modifying the data packet sending state information into second data packet receiving state information with the content of transmission failure in response to the analysis result being an information transmission error, and constructing second feedback information according to the second data packet receiving state information.
When the analysis result is that the information transmission is wrong, the execution main body can modify the data packet sending state information into second data packet receiving state information with the content of transmission failure. For example, the second packet reception state information may be "011". Where "011" may indicate incomplete. Other transmission failures may also be: "001" indicates retry; "010" means empty packet; "100" means ignore; "101" means repetition, etc. Similar to the first feedback information, the second feedback information may include only the second packet reception status information, or may include the data amount information and the data compression packet of the data compression packet in the packet transmission status information.
With continuing reference to fig. 4, fig. 4 is a schematic diagram of an application scenario of the method for synchronizing information according to the present embodiment. In the application scenario of fig. 4, when information to be synchronized is needed on the synchronization node 104, the synchronization node 104 encapsulates the information to be synchronized into a data packet to be synchronized, and sends the data packet to the node to be synchronized 101 and the node to be synchronized 102 through the network 103. Then, the node to be synchronized 101 and the node to be synchronized 102 send feedback information to the synchronization node 104 according to the received actual information. If the feedback information of the node to be synchronized 101 received by the synchronization node 104 is successful in transmission, the synchronization node 104 does not send a data packet to be synchronized to the node to be synchronized 101 any more; if the feedback information of the node to be synchronized 101 received by the synchronization node 104 is a transmission failure, the synchronization node 104 sends the data packet to be synchronized to the node to be synchronized 102 again until the node to be synchronized 102 successfully receives the data packet to be synchronized.
The method provided by the embodiment of the disclosure firstly encapsulates the information to be synchronized into a data packet to be synchronized when the information to be synchronized is detected; then, the data packet to be synchronized is sent to a node to be synchronized through a user data protocol; and finally, when receiving the feedback information sent by the node to be synchronized, completing information synchronization according to the feedback information. According to the method and the device, information transmission is carried out through the user data protocol when information synchronization is needed, the nodes do not need to be in communication connection for a long time through heartbeat detection, and the problems of information concurrency and the like do not need to be considered. Therefore, the data processing amount of the nodes is reduced, the information synchronization process is simplified, and the effectiveness of the information synchronization is improved.
