In a fifth aspect, the present application shows a computer program product, in which instructions, when executed by a processor of an electronic device, enable the electronic device to perform the method according to any of the preceding aspects.

Compared with the prior art, the method has the following advantages:

in this application, when the connection of the first data plane is not disconnected, at least one second network path between the first node and the second node is detected according to a component of a control plane of the first node, where the second network path is different from the first network path that carries the connection of the first data plane. And establishing at least one second data plane connection between the first node and the second node according to the control plane component in the first node, the connection of the first control plane and at least one second network path. And under the condition that the connection of the first data plane between the first node and the second node is disconnected and the connection of at least one second data plane is not disconnected, switching the data message needing to be transmitted between the first node and the second node to the connection transmission of the second data plane which is not disconnected according to the data plane component in the first node.

According to the method and the device, under the condition that the connection of the first data plane between the first node and the second node is not disconnected, the connection of at least one second data plane between the first node and the second node is established to serve as a backup of the connection of the data planes, and the second network path for bearing the connection of the second data plane is different from the first network path for bearing the connection of the first data plane.

In this way, in case of a disconnection of the first data plane due to a blocking of the first network path (network black hole), it does not necessarily lead to a blocking of the second network path, thereby not necessarily causing the disconnection of the second data plane, indirectly reducing the influence degree of the network black hole on the connection of the data plane between the first node and the second node, under the condition that the connection of the second data plane is not disconnected, the data message needing to be transmitted between the first node and the second node can be directly switched to the connection of the second data plane which is not disconnected for transmission, to avoid as far as possible waiting for the process of restoring the connection of the data plane between the first node and the second node, and may reduce the extent to which the transmission of data packets between the first node and the second node is affected, e.g., the time length for which the transmission of the data packet between the first node and the second node is interrupted can be reduced.

For example, in the present application, the connection of the second data plane is established based on the connected second network path "detected without disconnecting the connection of the first data plane", and instead of performing one detection to obtain one connected second network path, one connected second network path may not be obtained by performing one detection while detecting the second network path between the first node and the second node based on the component of the control plane in the first node, but in the present application, even if the connection of the first data plane is not disconnected, the connected second network path is not successfully obtained when detecting the network path, the detection may be continued until at least one connected second network path between the first node and the second node is detected, and then the connection of the second data plane between the first node and the second node may be established based on the at least one connected second network path, as a backup for the connection of the data plane. Then, under the condition that the connection of the first data plane between the first node and the second node is disconnected and the connection of at least one second data plane is not disconnected, the data message needing to be transmitted between the first node and the second node can be directly switched to the connection transmission of the second data plane which is established in advance and is not disconnected according to the component of the data plane in the first node. The second network path does not need to be detected in real time, and then the connection of the second data plane is established in real time based on the connected network path obtained by detection, so that the time consumed in the process of detecting the second network path in real time (secondly, more time delay caused by unsuccessful detection for many times) is saved, the time for establishing the connection of the second data plane in real time is saved, the degree of influence on the transmission of the data message between the first node and the second node can be reduced as much as possible, for example, the time for interruption of the transmission of the data message between the first node and the second node can be reduced, and the like.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

The connection of the control plane between two nodes in the network may be established based on one network path, which may include a plurality of other nodes, or based on one network path, which may include a plurality of other nodes.

However, a network path carrying a connection of the data plane may be blocked sometimes, which results in that the network path is not smooth, and further results in that the connection of the data plane is disconnected, which may result in that data packets between the two nodes cannot be transmitted normally.

In a possible case, a network path carrying a connection of a control plane between two nodes is the same as a network path carrying a connection of a control data plane between two nodes, so that, in the case of network path blocking, the connection of the control plane and the connection of the data plane between two nodes are both disconnected, resulting in that data packets cannot be normally transmitted between the two nodes.

In order to enable the two nodes to normally transmit the data packets, the connection of the data plane between the two nodes needs to be restored, but if the connection of the data plane between the two nodes needs to be restored.

However, it takes a while to restore the connection of the data plane between the two nodes, which may aggravate the affected degree of the data packet transmission between the two nodes.

Therefore, in order to reduce the affected degree of data packet transmission between two nodes as much as possible, referring to fig. 1, a flowchart of a data packet transmission method in a network according to the present application is shown.

The network includes a plurality of nodes, each of which includes control plane components and data plane components.

The embodiments of the present application are illustrated by taking a first node and a second node in a network as examples, but the present application is not limited to the scope of protection.

The first node and the second node in the network are connected through a first data plane, and data messages can be transmitted between the first node and the second node based on the connection of the first data plane.

A first node in the network has a first control plane connection with a second node in the network, and a data plane connection between the first node in the network and the second node in the network may be established based on the first control plane connection, and so on.

In the method, the flow of the method is described with the first node as an execution subject, but not as a limitation to the scope of the present application, specifically, the method includes:

in step S101, if the connection of the first data plane is not disconnected, at least one second network path between the first node and a second node is detected according to a component of the control plane of the first node, where the second network path is different from the first network path carrying the connection of the first data plane.

In this application, in a general case, a connection of a first data plane between a first node and a second node is connected, and a data packet may be transmitted between the first node and the second node based on the connection of the first data plane.

However, sometimes, a first network path between a first node and a second node may be blocked (e.g., a network black hole, etc.) under a possible scenario, for example, a node in the first network path goes down, causing a first network path between the first node and the second node to be blocked, etc., which may cause the first data plane between the first node and the second node to be disconnected if the first network path between the first node and the second node is blocked.

If the connection of the first data plane between the first node and the second node is disconnected, the connection of the data plane capable of transmitting the data message is lost between the first node and the second node, and further the data message cannot be transmitted between the first node and the second node, so that the transmission of the data message is interrupted.

Therefore, when the connection of the first data plane between the first node and the second node is disconnected, the connection of the data plane between the first node and the second node can be recovered as soon as possible, so that the transmission of the data packet can be recovered as soon as possible between the first node and the second node.

In order to recover the connection of the data plane between the first node and the second node as soon as possible, in the present application, when the connection of the first data plane is not disconnected, at least one connection of the second data plane between the first node and the second node may be additionally established as a backup, and a first network path carrying the connection of the first data plane needs to be different from a second network path carrying the connection of the second data plane.

Therefore, under the condition that the first network path is blocked to cause the disconnection of the first data plane, if the second network path is not disconnected, the connection of the second data plane is connected and available, and therefore, the data message between the first node and the second node can be transmitted continuously by directly using the connection of the connected second data plane, so that the transmission of the data message can be recovered as soon as possible between the first node and the second node.

In order to additionally establish a connection of the second data plane between the at least one first node and the second node as a backup, in this application, in a case that the connection of the first data plane is not disconnected, the at least one second network path between the first node and the second node may be detected according to a component of the control plane of the first node, and then step S102 is performed. The second network path is different from the first network path carrying the connection of the first data plane.

In step S102, a connection of at least one second data plane between the first node and the second node is established according to the component of the control plane in the first node, the connection of the first control plane, and the at least one second network path.

For any one detected second network path between the first node and the second node, the second network path is associated with the IP address of the first node, a port number of the first node, the IP address of the second node, and a port number of the second node. The same is true for every other second network path between the first node and the second node that is detected. And the port numbers of the associated first nodes in different second network paths are different and/or the port numbers of the associated second nodes are different, etc.

For any detected second network path between the first node and the second node, when a connection of a second data plane between the first node and the second node, which is carried by the network path, needs to be established, a connection establishment request message may be sent to the second node through a connection of the first control plane according to a component of the control plane in the first node, where the connection establishment request message carries an IP address of the first node, a port number of the first node, an IP address of the second node, and a port number of the second node, which are associated with the second network path, and the component of the control plane in the second node receives the connection establishment request message, activates the port number in the second node according to the port number of the second node carried in the connection establishment request message, so as to assign the port number in the second node to the first node, and then may send a connection establishment response message to a component of the control plane in the first node, and the control plane component in the first node receives the connection establishment response message, so that the connection of the second data plane carried by the second network path is established between the first node and the second node.

The same is true for every other second network path between the first node and the second node that is detected. Thereby enabling the establishment of a connection of at least one second data plane between the first node and the second node.

In step S103, when the connection of the first data plane between the first node and the second node is disconnected and the connection of at least one second data plane is not disconnected, the data packet to be transmitted between the first node and the second node is switched to the connection transmission of the second data plane that is not disconnected according to the component of the data plane in the first node.

In step S101 and step S102, a connection having a first data plane and at least one second data plane between the first node and the second node can be realized.

In one case, the first node and the second node transmit data packets to each other based on the connection of the first data plane, if the connection of the first data plane between the first node and the second node is disconnected, the first node and the second node cannot transmit data packets to each other based on the connection of the first data plane, however, if at least one second data plane is not disconnected, the first node and the second node can continue to transmit data packets to each other based on the connection of one of the second data planes, and thus, the data packets to be transmitted between the first node and the second node can be switched to the connection of the second data plane which is not disconnected according to the component of the data plane in the first node.

In this application, the third network path carrying the connection of the first control plane may be the same as or different from the second network path.

Under the condition that the third network path is the same as the second network path, the network path carrying the connection of the second data plane is the same as the network path carrying the connection of the first control plane, if the third network path is blocked, the second network path is blocked, which can cause the disconnection of both the connection of the second data plane and the connection of the first control plane.

Secondly, since the connection of the first control plane is also disconnected, if the connection of the data plane between the first node and the second node is to be restored, the connection of the control plane between the first node and the second node needs to be restored first, however, a period of time is consumed in the process of restoring the connection of the control plane between the first node and the second node, the process of restoring the connection of the data plane between the first node and the second node is delayed, the efficiency of restoring the connection of the data plane between the first node and the second node is reduced, and the transmission of the data packet between the first node and the second node is further affected.

Therefore, in order to solve the above problem, in another embodiment of the present application, the third network path of the connection carrying the first control plane is different from the second network path, for example, when at least one second network path between the first node and the second node is detected according to the component of the control plane of the first node in step S101, the third network path can be bypassed to detect the second network path between the first node and the second node, so that the detected second network path between the first node and the second node is different from the third network path of the connection carrying the first control plane.

Since the second network path carrying the connection of the second data plane is different from the third network path carrying the connection of the first control plane, if the third network path is blocked, the disconnection of the first control plane may be caused, but the blocking of the second network path may not necessarily be caused, that is, the disconnection of the second data plane may not necessarily be caused.

Under the condition that the second network path is not blocked, the connection of the second data plane is not disconnected, that is, the connection of the second data plane is connected, the first node and the second node can still transmit the data message based on the connection of the second data plane, and the condition that the data message cannot be transmitted between the first node and the second node due to the blockage of the third network path and the connection of the data plane which is not connected between the first node and the second node does not exist can not occur, so that the transmission of the data message between the first node and the second node can be avoided being influenced.

Or, in another embodiment of the present application, other available network paths different from the second network path and the third network path between the first node and the second node may be detected according to a component of the control plane of the first node, and a connection of another control plane for communicating between the first node and the second node is established based on the detected other network paths, so as to back up the connection of the control plane.

Thus, if the connection of the first control plane is disconnected, and the connection of the first data plane and the disconnection of the second data plane are disconnected, the connection of the connected data plane does not exist between the first node and the second node, and further the data message cannot be transmitted between the first node and the second node, because the first node and the second node are connected by other communicated control planes, the connection of the data plane between the first node and the second node can be restored directly according to the connection of other communicated control planes, thereby avoiding the situation that the connection of the control plane between the first node and the second node needs to be restored in real time, and then the connection of the data plane between the first node and the second node is restored according to the connection of the restored control planes, the efficiency of recovering the connection of the data plane between the first node and the second node is improved, and the transmission of the data message between the first node and the second node is prevented from being influenced as much as possible.

Based on the foregoing illustrated embodiments, in a possible case, in a case where the connection of the first data plane between the first node and the second node is disconnected, the previously established connection of the second data plane between the first node and the second node is disconnected (for example, the connection of the second data plane is disconnected due to the second network path blocking).

In this case, at this time, there is no connection of the connected data plane between the first node and the second node, which results in that the data packet cannot be transmitted between the first node and the second node, and therefore, the connection of the connected data plane between the first node and the second node needs to be established in real time to recover the transmission of the data packet between the first node and the second node.

In an example, if the connection of the first control plane is not disconnected, at least one fourth network path may be detected in real time between the first node and the second node according to a component of the control plane in the first node, and in this application, the fourth network path that needs to be detected is a connected network path but cannot be a blocked network path, so that the detected fourth network path may be different from the first network path and different from the second network path, and then the connection of at least one third data plane between the first node and the second node may be established according to the component of the control plane in the first node, the connection of the first control plane, and the at least one fourth network path. The specific manner of establishing the connection of the third data plane may refer to the description of establishing the connection of the second data plane in step S102, and is not described in detail here. And then, according to the data plane component in the first node, switching the data message needing to be transmitted between the first node and the second node to the connection transmission of at least one third data plane.

In this application, the third network path and the fourth network path carrying the connection of the first control plane may be the same or different.

Under the condition that the third network path is the same as the fourth network path, the network path carrying the connection of the third data plane is the same as the network path carrying the connection of the first control plane, if the third network path is blocked, the fourth network path is blocked, which can cause the disconnection of both the connection of the third data plane and the connection of the first control plane.

Therefore, in order to solve the above problem, in another embodiment of the present application, the third network path of the connection carrying the first control plane is different from the fourth network path, for example, when at least one fourth network path between the first node and the second node is detected according to the component of the control plane of the first node, the third network path may be bypassed to detect the fourth network path between the first node and the second node, so that the detected fourth network path between the first node and the second node is different from the third network path of the connection carrying the first control plane.

Since the fourth network path carrying the connection of the third data plane is different from the third network path carrying the connection of the first control plane, if the third network path is blocked, the connection of the first control plane is disconnected, but the fourth network path is not necessarily blocked, that is, the connection of the third data plane is not necessarily disconnected.

Under the condition that the fourth network path is not blocked, the connection of the third data plane is not disconnected, that is, the connection of the third data plane is connected, the first node and the second node can still transmit the data message based on the connection of the third data plane, and the situation that the data message cannot be transmitted between the first node and the second node due to the fact that the third network path is blocked and the connected data plane does not exist between the first node and the second node is not connected can not occur, so that the data message can be prevented from being transmitted between the first node and the second node.

Or, in another embodiment of the present application, other available network paths different from the fourth network path and the third network path between the first node and the second node may be detected according to a component of the control plane of the first node, and a connection of another control plane for communicating between the first node and the second node is established based on the detected other network paths, so as to back up the connection of the control plane.

Thus, if the connection of the first control plane is disconnected, the connection of the first data plane is disconnected, the connection of the second data plane is disconnected and the connection of the third data plane is disconnected, so that the connection of the communicated data plane does not exist between the first node and the second node, and further the transmission of the data message cannot be carried out between the first node and the second node, because the first node and the second node are connected by other communicated control planes, the connection of the data plane between the first node and the second node can be directly restored according to the connection of the other communicated control planes, thereby avoiding the situation that the connection of the control plane between the first node and the second node needs to be restored in real time first, and then the connection of the data plane between the first node and the second node is restored according to the restored connection of the control planes, and improving the efficiency of restoring the connection of the data plane between the first node and the second node, in order to avoid as far as possible affecting the transmission of data packets between the first node and the second node.

Based on the foregoing illustrated embodiments, in a possible case, in the case that the connection of the first data plane between the first node and the second node is broken, the previously established connection of the second data plane between the first node and the second node is broken (for example, the connection of the second data plane is broken due to the second network path blocking), and the connection of the first control plane is also broken (for example, the connection of the first control plane is broken due to the third network path blocking).

However, at this time, there is no connection of the connected control plane between the first node and the second node, and in order to establish a connection of the connected data plane between the first node and the second node to recover transmission of the data packet between the first node and the second node, the connection of the control plane between the first node and the second node needs to be recovered first.

In order to restore the connection of the control plane between the first node and the second node, at least one fifth network path may be probed in real time between the first node and the second node according to a component of the control plane in the first node.

In the application, the fifth network path to be detected is a connected network path but cannot be a blocked network path, and therefore, the detected fifth network path may be different from the first network path, the second network path, and the third network path, and then the connection of the second control plane between the first node and the second node may be established according to the component of the control plane in the first node and the fifth network path; establishing at least one fourth data plane connection between the first node and the second node according to the control plane component in the first node, the second control plane connection and at least one fifth network path; the specific establishment manner of establishing the connection of the fourth data plane may refer to the description of establishing the connection of the second data plane in step S102, and is not described in detail here. And then, according to the data plane component in the first node, switching the data message needing to be transmitted between the first node and the second node to the connection transmission of at least one fourth data plane.

In this application, the fifth network path carrying the connection of the second control plane and the fifth network path carrying the connection of the fourth data plane may be the same or different.

Under the condition that a fifth network path for carrying the connection of the second control plane is the same as a fifth network path for carrying the connection of the fourth data plane, if the fifth network path for carrying the connection of the second control plane is blocked, the fifth network path for carrying the connection of the fourth data plane is blocked, which may result in disconnection of both the connection of the fourth data plane and the connection of the second control plane, and as the connection of the first data plane is also disconnected and the connection of the second data plane is also disconnected, there may be no connection of the data plane between the first node and the second node, and further, data packet transmission between the first node and the second node may not be performed.

Secondly, since the connection of the second control plane is also disconnected, if the connection of the data plane between the first node and the second node is to be restored, the connection of the control plane between the first node and the second node needs to be restored first, however, a period of time is consumed in the process of restoring the connection of the control plane between the first node and the second node, the process of restoring the connection of the data plane between the first node and the second node is delayed, the efficiency of restoring the connection of the data plane between the first node and the second node is reduced, and the transmission of the data packet between the first node and the second node is further affected.

Therefore, in order to solve the above problem, in another embodiment of the present application, at least two fifth network paths are detected, and different fifth network paths are different; the fifth network path carrying the connection of the second control plane is different from the fifth network path carrying the connection of the fourth data plane.

For example, when detecting at least one fifth network path between the first node and the second node according to the component of the control plane of the first node, the fifth network path carrying the connection of the second control plane may be bypassed to detect the other fifth network path between the first node and the second node, such that the detected fifth network path for establishing the connection of the data plane between the first node and the second node is different from the fifth network path carrying the connection of the second control plane.

Since the fifth network path carrying the connection of the fourth data plane is different from the fifth network path carrying the second control plane, if the fifth network path carrying the connection of the second control plane is blocked, the connection of the second control plane may be disconnected, but the fifth network path carrying the connection of the fourth data plane may not be blocked necessarily, that is, the connection of the fourth data plane may not be disconnected necessarily.

Under the condition that a fifth network path for carrying the connection of the fourth data plane is not blocked, the connection of the fourth data plane is not disconnected, that is, the connection of the fourth data plane is connected, the first node and the second node can still transmit the data message based on the connection of the fourth data plane, and the condition that the data message cannot be transmitted between the first node and the second node due to the fact that the fifth network path for carrying the connection of the second control plane is blocked can not occur, so that the transmission of the data message between the first node and the second node can be avoided being influenced.

Or, in another embodiment of the present application, other available network paths between the first node and the second node and different from the fifth network path carrying the connection of the fourth data plane and the fifth network path carrying the connection of the second control plane may be detected according to a component of the control plane of the first node, and the connection of the other control planes communicating between the first node and the second node is established based on the detected other network paths, so as to back up the connection of the control plane.

Thus, if the second control plane is disconnected, the first data plane is disconnected, the second data plane is disconnected and the fourth data plane is disconnected, so that the first node and the second node are not connected by the connected data plane, and further the first node and the second node cannot transmit data messages, because the first node and the second node are connected by other connected control planes, the connection of the data plane between the first node and the second node can be directly recovered according to the connection of the other connected control planes, thereby avoiding the situation that the connection of the control plane between the first node and the second node needs to be recovered in real time first, and then the connection of the data plane between the first node and the second node is recovered according to the recovered connection of the control plane, so as to improve the efficiency of recovering the connection of the data plane between the first node and the second node, in order to avoid as far as possible affecting the transmission of data packets between the first node and the second node.
