For one OVSDB server, the connected OVSDB clients include a main OVSDB client, and the OVSDB clients except the main OVSDB client in the connected OVSDB clients are all standby OVSDB clients of the main OVSDB client.

In practical applications, a plurality of OVSDB clients may be installed on one ONOS node 10, and each OVSDB client is a client of a different OVSDB server.

With reference to the application scenario diagram shown in fig. 1, the present embodiment provides an information processing method, which can solve the problem of inconsistency of configuration data in an ONOS node and an OVSDB server, and ensure synchronization of the configuration data in the ONOS node and the OVSDB server.

The functions implemented by the method may be implemented by calling program code by a processor in a computer device, which may, of course, be stored in a computer storage medium, which may comprise at least a processor and a storage medium.

Fig. 2 is a schematic flow chart of an implementation of an information processing method according to an embodiment of the present application, and as shown in fig. 2, the method may include the following steps:

s201, obtaining configuration data in an ONOS node of an open network operating system to obtain first configuration data.

In this embodiment of the application, the current ONOS node may be a master node in the ONOS cluster or may be a standby node in the ONOS cluster.

In an example, the current ONOS node is a master node, receives configuration data sent by a user through an upper layer based on an interface between the master ONOS and the upper layer, and synchronizes the configuration data to a standby node through connection between the ONOS node and the standby node, so that distributed storage of the configuration data in the ONON cluster is realized, and the configuration data of each ONOS node in the ONON cluster is consistent.

The configuration data may include: network topology configuration, Network interface configuration (such as IP address), routing configuration, Virtual Local Area Network (VLAN) configuration, flow table configuration, and other Network configurations of the Virtual Network. The content of the configuration data is not limited in any way in the embodiments of the present application.

In an example, the current ONOS node is a standby node, and receives configuration data sent by the master node, and updates the configuration data.

After receiving the configuration data, the ONOS node configures the ONOS node by the configuration data on one hand, and caches the configuration data on the other hand, so that the cached configuration data is issued to the OVSDB client by the OVSDB client in the ONOS node after the configuration is finished.

And the ONOS node acquires the latest configuration data according to the configuration condition of the ONOS node, wherein the acquired configuration data is not the cached configuration data, so that the situation that the acquired configuration data is not the latest configuration data under the conditions of cache configuration data loss and disorder is avoided.

In the embodiment of the present application, the latest configuration data of the ONOS node is referred to as first configuration data, and the ONOS may acquire a plurality of pieces of the first configuration data.

S202, obtaining configuration data in an OVSDB client of an open virtual switch database corresponding to the ONOS node to obtain second configuration data, wherein the OVSDB client is located in the ONOS node.

And the ONOS node acquires the configuration data of the OVSDB client on the ONOS node, wherein the configuration data of the OVSDB client acquired by the ONOS node is all the configuration data of the OVSDB server. The OVSDB client and the OVSDB server communicate with each other through an OVSDB protocol, and the OVSDB client automatically synchronizes all configuration data of the OVSDB server to the local OVSDB client based on the characteristics of the OVSDB protocol. In practical application, the OVSDB server synchronizes its configuration data to all connected OVSDB clients.

In this embodiment, the configuration data of the OVSDB client acquired by the ONOS node is referred to as second configuration data, and the ONOS may acquire a plurality of pieces of the second configuration data.

In the embodiment of the present application, the execution sequence of S201 and S202 is not limited at all.

The ONOS node may acquire its own first configuration data based on a preset trigger condition, and acquire its own second configuration data based on the acquisition of its own first configuration data. The ONOS node may acquire the second configuration data based on a preset trigger condition and acquire the first configuration data of itself based on the acquisition of the second configuration data. Wherein the trigger condition may include: when the current time reaches a specified time point, the switching of the main and standby nodes in the ONOS cluster is detected, the OVSDB client on the current ONOS node is switched from the main client of the connected OVSDB server to the standby client, and the like.

In practical application, the OVSDB client can determine to which OVSDB server the received configuration data is to be issued, and at this time, only the configuration data of the OVSDB server may be obtained to obtain the second configuration data, and the configuration data of the OVSDB server is configured based on a comparison result of the first configuration data and the second configuration data.

S203, comparing the first configuration data with the second configuration data to obtain a comparison result.

And after the ONOS node acquires the first configuration data and the second configuration data, comparing the first configuration data with the second configuration data, searching for configuration differences existing between the first configuration data and the second configuration data, and generating a comparison result according to a search result. Here, the comparison result is only whether the first configuration data and the second configuration data are the same or not, and is different in the case where the first configuration data and the second configuration data are different.

In an example, the alignment results may include a first alignment result characterizing a configuration difference between the first configuration data and the second configuration, and a second alignment result characterizing an absence of a configuration difference between the first configuration data and the second configuration data.

And when the comparison result is the first comparison result, the current configuration data representing the ONOS node is consistent with the configuration data of the OVSDB service end, and when the comparison result is the first comparison result, the current configuration data representing the ONOS node is inconsistent with the configuration data of the OVSDB service end.

It should be noted that, in the embodiment of the present application, the comparison method for comparing the first configuration data with the second configuration data may include the following three methods or other methods capable of determining the difference: in the mode 1, first traversing the first configuration data and then traversing the second configuration data; mode 2, or first traverse the second configuration data, then traverse the first configuration data; mode 3, the first configuration data and the second configuration data are traversed simultaneously. In the embodiment of the present application, the comparison process between the first configuration data and the second configuration data is not limited at all.

And S204, generating a sending instruction according to the comparison result, and configuring configuration data in an OVSDB server corresponding to the OVSDB client through the sending instruction.

And the ONOS node generates a sending instruction according to the comparison result so as to indicate whether the OVSDB server side modifies the configuration data or not and update the content under the condition of updating the configuration data through the sending instruction.

In an example, the ONOS node periodically sends a heartbeat packet to the OVSDB server based on a connection between the OVSDB client and the OVSDB server and a heartbeat detection mechanism exists between the ONOS node and the OVSDB server. And the ONOS node can send a sending command to the OVSDB server side through a sending channel of the heartbeat packet while sending the heartbeat packet.

In another example, the ONOS node sends the issue instruction to the OVSDB server if it determines that the connection with the OVSDB server is connected through the heartbeat packet.

In practical application, the ONOS node may generate a sending instruction corresponding to the first comparison result or a sending instruction corresponding to the second comparison result when the comparison result is the first comparison result or the second comparison result, at this time, a synchronization identifier may be carried in the sending instruction to indicate whether the configuration of the ONOS node is consistent with the configuration of the OVSDB service end, or the ONOS node may generate a sending instruction only when the comparison result is the first comparison result and send the sending instruction to the OVSDB service end to indicate that the configuration of the OVSDB service end is inconsistent with the configuration data of the ONOS node, and it is necessary to update the configuration data, and indicate how to update the configuration data.

In the embodiment of the application, when the first configuration data and the second configuration data have configuration differences, the issued instruction can indicate the configuration data which needs to be added, modified or deleted by the OVSDB server.

In the information processing method provided by the embodiment of the application, the ONOS node determines whether the configuration data of the OVSDB server corresponding to the ONOS node and the OVSDB client are the same or not by comparing the configuration data of the ONOS node with the configuration data of the OVSDB client on the ONOS node with the configuration data of the OVSDB server corresponding to the OVSDB client, and updates the configuration data of the OVSDB server based on the comparison result, so that the occurrence of the situation that the configuration data of the ONOS node and the OVSDB server are inconsistent can be found in time, the data of the OVSDB server is recovered, the problem that the configuration data in the ONOS node and the ovsdsdb server are inconsistent is solved, and the synchronization of the configuration data in the ONOS node and the sdovsdb.

In some embodiments, as shown in fig. 3, before S201, the method further includes:

s301, detecting whether the OVSDB client executes the master-slave switching event.

And the ONOS node detects whether the OVSDB client on the ONOS node has execution of the master-slave switching event. In the embodiment of the present application, the OVSDB client may execute the active/standby switching event under one of the following conditions:

the connection between the OVSDB client and the OVSDB server is disconnected;

the ONOS node processes are abnormal or powered down.

The disconnection between the OVSDB client and the OVSDB server can be caused by the ONOS node or the OVSDB server. Under the condition caused by the ONOS node, when the ONOS node is crashed or abnormal, the connection between the OVSDB client and the OVSDB server is disconnected. Under the condition caused by the OVSDB server, the ONOS node detects that the OVSDB server is disconnected.

S302, when the OVSDB client executes a master-slave switching event, triggering an acquisition instruction, wherein the acquisition instruction is used for acquiring the first configuration data and the second configuration data.

And the ONOS node detects that the OVSDB client has a main/standby switching event, and triggers an acquisition instruction for indicating the ONOS node to acquire the first configuration data and the second configuration data based on the main/standby switching event.

In the information processing method provided by the embodiment of the application, the ONOS node acquires the first configuration data and the second configuration data when detecting that the OVSDB client has the master-slave switching event, and compares the first configuration data with the second configuration data, thereby determining whether an abnormal condition causing the master-slave switching event affects the configuration data cached in the ONOS node, and finding out a condition that the configuration data in the ONOS node is inconsistent with the configuration data in the OVSDB server in time.

In some embodiments, as shown in fig. 4, the implementation of S203 includes:

s401, with the first configuration data as a reference standard, judging whether the second configuration data and the first configuration data have configuration difference.

In the embodiment of the application, the first configuration data is used as a reference standard to search for the difference between the second configuration data and the first configuration data. Here, the first configuration data and the second configuration data may be traversed, respectively, to determine the configuration difference between the second configuration data and the first configuration data.

In some embodiments, the implementation of S401 comprises: in some embodiments, the determining whether there is a configuration difference between the second configuration data and the first configuration data by using the first configuration data as a reference standard includes: comparing the configuration identifier of the first configuration data with the configuration identifier of the second configuration data, and determining whether the configuration identifier of the first configuration data and the configuration identifier of the second configuration data include a first configuration identifier, a second configuration identifier and a third configuration identifier, where the first configuration identifier is a configuration identifier included in both the configuration identifier of the first configuration data and the configuration identifier of the second configuration data, the second configuration identifier is a configuration identifier not included in the configuration identifier of the first configuration data but included in the configuration identifier of the second configuration data, and the third configuration identifier is a configuration identifier included in the configuration identifier of the first configuration data but not included in the configuration identifier of the second configuration data; when the configuration identifier including the first configuration data and the configuration identifier including the second configuration data include the first configuration identifier, comparing third configuration data corresponding to the first configuration identifier in the first configuration data with fourth configuration data corresponding to the first configuration identifier in the second configuration data, and judging whether data difference exists between the third configuration data and the fourth configuration data.

Here, the ONOS node may first traverse the difference between the configuration identifier of the first configuration data and the configuration identifier of the second configuration data to see which configuration data is included in both the first configuration data and the second configuration data, which configuration data is not included in the first configuration data but is included in the second configuration data, and which configuration data is included in the first configuration data but not included in the second configuration data. Here, the configuration identifier included in both the first configuration data and the second configuration data is referred to as a first configuration identifier, the configuration identifier not included in the first configuration data but included in the second configuration data is referred to as a second configuration identifier, and the configuration identifier included in the first configuration data but not included in the second configuration data is referred to as a third configuration identifier.

For the first configuration identifier, the ONOS node needs to further check whether the data content of the first configuration data, i.e., the third configuration data, and the second configuration data, i.e., the fourth configuration data, having the same configuration identifier are the same, and determine the data difference between the third configuration data and the fourth configuration data if the data content of the first configuration data and the data content of the second configuration data, i.e., the fourth configuration data, are not the same.

In practical application, the third configuration data may be subjected to format conversion, and compared with the fourth configuration data after being converted into the OVSDB format, so as to obtain a data difference between the third configuration data and the fourth configuration data.

In an example, the first configuration data includes: configuration data A, configuration data B and configuration data C, wherein the second configuration data comprises: configuration data a, configuration data C, and configuration data D, wherein A, B, C, D are identifiers of the configuration data, respectively, and the first configuration identifier includes: a and C, the second configuration identifier comprises: d, the third configuration identifier comprises B. And under the condition that the ONOS node determines that the first configuration identifier exists, checking whether the configuration data A in the first configuration data is the same as the configuration data A in the second configuration data and whether the configuration data C in the first configuration data is the same as the configuration data C in the second configuration data.

S402, when the second configuration data and the first configuration data have configuration difference, obtaining a first comparison result representing the configuration difference.

When the comparison result of the first configuration data and the second configuration data comprises at least one of the following results, the generated comparison result is the first comparison result: the second configuration identifier, the third configuration identifier, or the third configuration data and the fourth configuration data are different.

S403, when no configuration difference exists between the second configuration data and the first configuration data, generating a second comparison result.

And when the comparison result of the first configuration data and the second configuration data does not include the second configuration identifier and the third configuration identifier, and the third configuration data and the fourth configuration data are not different, the generated comparison result is the second comparison result.

In some embodiments, the implementation of S204 includes: and when the comparison result is the first comparison result, generating the issuing instruction according to the first comparison result.

Here, according to the different results included in the first comparison result, the generating of the issuing command includes the following three cases:

in case 1, when the first comparison result includes a first configuration identifier and a data difference corresponding to the first configuration identifier, a configuration data modification instruction indicating that the configuration data corresponding to the first configuration identifier is modified according to the data difference is generated, where the first configuration identifier is a configuration identifier included in both the configuration identifier of the first configuration data and the configuration identifier of the second configuration data.

And 2, when the comparison result includes a second configuration identifier, generating a configuration data deleting instruction for indicating to delete the configuration data corresponding to the second configuration identifier according to the second configuration identifier, where the second configuration identifier is a configuration identifier that is not included in the configuration identifiers of the first configuration data but is included in the configuration identifiers of the second configuration data.

And 3, when the comparison result includes a third configuration identifier, generating a configuration data adding instruction for indicating to add configuration data corresponding to the third configuration identifier according to the configuration data corresponding to the third configuration identifier, where the third configuration identifier is a configuration identifier included in the configuration identifier of the first configuration data but not included in the configuration identifier of the second configuration data.

When the first comparison result is the result of the condition 1, the fact that the first configuration data and the second configuration data have the same configuration identifier but different configuration data corresponding to the configuration identifier is characterized, the issued instruction comprises a modification instruction to indicate that the OVSDB server modifies the fourth configuration data according to the third configuration data corresponding to the first configuration identifier in the first configuration data, the third configuration data is modified, and the configuration data in the same configuration identifier are the same. The modification instruction may include the third configuration data itself, or may only include a data difference between the third configuration data and the fourth configuration data.

And when the comparison file shows that the first comparison result is the result of the condition 2, the fact that a certain configuration data is not included in the first configuration data but exists in the second configuration data is represented, and a deleting instruction is issued to indicate that the OVSDB server needs to delete the configuration data.

And when the comparison result is that the first comparison result is in the condition 3, the fact that a certain piece of configuration data is included in the first configuration data but not included in the second configuration data is represented, and an adding instruction is issued to indicate that the OVSDB server needs to add the piece of configuration data.

In practical application, when the comparison result includes a combination of multiple situations, a set of instructions is used to simultaneously carry multiple update identifiers, so that different update marks correspond to different issued instructions.

The information processing method provided by the embodiment of the application can generate different issuing instructions based on different comparison results so as to correctly instruct the OVSDB server to update the configuration data and keep the configuration data consistent with the configuration data of the ONOS node.

The information processing method provided in the embodiment of the present application is further described below by taking a specific application scenario as an example.

In the related art, the structure of the ONOS network may be as shown in fig. 5, and includes: the interface 501, the ONOS node 502, the OVSDB server 503-1, the OVSDB server 503-2 and the OVSDB server 503-3. The ONOS node 502 includes OVSDB clients 504 of OVSDB server 503-1, OVSDB server 503-2, and OVSDB server 503-3. Wherein, the interface 501 may be restful api.

The process of sending down the configuration data of the network shown in fig. 5 includes: the user issues configuration data to the ONOS node 402 through the interface 401, and the ONOS node 402 stores the configuration data and returns the storage result to the user. The ONOS node 402 processes and distributes the stored configuration through a message notification mechanism, and then issues to the OVSDB server 403-1, the OVSDB server 403-2 and the OVSDB server 403-3 through the OVSDB client 404 by adopting an OVSDB protocol.

Here, when the ONOS node 402 may be stored in a distributed manner with other ONOS nodes in the ONOS network, the configuration data of all ONOS nodes may be consistent.

However, the configuration data issuing process has an asynchronous process: the configuration data is cached in the ONOS node, so that the cached configuration data is possibly discarded after the ONOS node is abnormal, and an upper-layer user cannot perceive the configuration data. And the ONOS node has the following technical defects:

1. if the ONOS node flow is abnormal or the process is abnormal, the configuration data cached in the asynchronous message queue is lost, the user cannot perceive the configuration data, and the cached configuration data cannot be recovered.

2. The physical environment of the ONOS node is powered off, the cache message is lost, the user cannot perceive the loss, and the cached configuration data cannot be recovered.

3. And switching between the main and standby ONOS nodes in the ONOS cluster, and repeatedly issuing the cached configuration data out of order or losing the configuration data to cause configuration data errors or losses.

4. The ONOS node and the OVSDB server have short-term network disconnection, so that configuration data is lost and cannot be recovered.

The information processing method provided by the embodiment of the application can enable the configuration data to be smoothly issued, and can ensure that the configuration is correct and not lost and the configuration is consistent from top to bottom under various abnormal scenes such as network abnormality, equipment power failure, cluster master-slave switching and the like. Even if the upper and lower configurations are not consistent in a complicated case, the recovery can be performed in a short period of time.

As shown in fig. 6, an information processing method provided in an embodiment of the present application includes:

s601, obtaining local storage data of the ONOS node and data of the OVSDB server stored by the OVSDB client.

And S602, comparing the difference data between the locally stored data of the ONOS node and the data of the OVSDB server side by taking the locally stored data of the ONOS node as a standard.

And S603, sending the compared difference data to an OVSDB server.

Here, the ONOS node, i.e., the ONOS control node, is connected to the OVSDB client (client), because of the features of the OVSDB protocol, the OVSDB client may automatically synchronize all configurations of the OVSDB server service to the OVSDB client locally, and by comparing the local storage of the ONOS node with the storage of the OVSDBclient, it may be determined whether the configurations of the ONOS node and the OVSDB service are consistent. Wherein, the ONOS node can be called a control layer, and the OVSDB service can be called a data forwarding layer.

And carrying out configuration comparison on the ONOS distributed storage, namely the local storage data of the ONOS node and the local storage of the OVSDB client, and making a difference on the local storage of the OVSDB client by taking the ONOS distributed storage as a reference.

Here, the local storage of the OVSDB client is traversed first, and configuration search is performed in the ONOS distributed storage by the ID of each configuration data. And for the found configuration, converting the ONOS storage data into an OVSDB format, comparing the OVSDB format with the local storage data of the OVSDB client, configuring and issuing the difference data by taking the configuration data of the ONOS as the standard, and identifying the compared ONOS storage data as compared. And for the configuration which is not found, the configuration which does not exist in the ONOS needs to delete the configuration data in the OVSDB service end. And then the ONOS distributed storage is performed, and the configuration data which is not identified and compared in the ONOS distributed storage is newly added in the OVSDB server, is converted into OVSDB data for configuration and issuing and is issued to the OVSDB server.

In the embodiment of the application, the local storage of the OVSDB client is differentiated and the difference is issued with the ONOS distributed storage as the standard, so that the aim of consistent configuration of the control layer and the data forwarding layer is fulfilled.

Here, the abnormal point of the ONOS is identified, a synchronization process is triggered, the characteristic that automatic synchronization data of an OVSDB protocol are transmitted to an OVSDB client is utilized for carrying out rapid comparison, the data of the ONOS node is consistent with the data of the OVSDB server, and the problem of configuration data loss or errors under the abnormal condition is solved.
