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

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

In the application, at least one second network path between the first node and the second node is detected from the components of the control plane of the first node, the second network path being different from the first network path carrying the connection of the first data plane, in the case that the connection of the first data plane is not broken. The connection of the at least one second data plane between the first node and the second node is established based on the components of the control plane in the first node, the connection of the first control plane and the at least one second network path. And under the condition that the connection of the first data surface between the first node and the second node is disconnected and the connection of at least one second data surface is not disconnected, switching the data message to be transmitted between the first node and the second node to the connection transmission of the second data surface which is not disconnected according to the components of the data surfaces in the first node.

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

In this way, under the condition that the connection of the first data surface is disconnected due to the first network path blocking (network black hole), the second network path blocking is not necessarily caused, and then the connection of the second data surface is not necessarily caused, so that the influence degree of the network black hole on the connection of the data surface between the first node and the second node is indirectly reduced, and under the condition that the connection of the second data surface is not disconnected, the data message to be transmitted between the first node and the second node can be directly switched to the connection transmission of the second data surface which is not disconnected, so that the process of waiting for restoring the connection of the data surface between the first node and the second node is avoided as much as possible, and the degree to which the transmission of the data message between the first node and the second node is influenced can be reduced, for example, the time length of the transmission of the data message 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 when the connection of the first data plane is not disconnected", instead of performing one detection to obtain one connected second network path in the process of 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, one connection of the second data plane between the first node and the second node may not be obtained by performing one detection, but in the present application, even if the connection of the first data plane is not disconnected, the detection may be continued until at least one connection 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 connection second network path as a backup of the connection of the data plane. And then under the condition that the connection of the first data surface between the first node and the second node is disconnected and the connection of at least one second data surface is not disconnected, the data message to be transmitted between the first node and the second node can be directly switched to the connection transmission of the second data surface which is not disconnected and is established in advance according to the components of the data surface in the first node. The connection of the second data plane is established in real time without detecting the second network path in real time and based on the detected connected network path, 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 avoided) is saved, and the time for establishing the connection of the second data plane in real time is saved, thereby reducing the degree to which the transmission of the data message between the first node and the second node is affected as much as possible, for example, reducing the time length for which the transmission of the data message between the first node and the second node is interrupted, and the like.

Detailed Description

In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description.

The connection of the control plane between two nodes in the network may be established based on a network path, possibly including a plurality of other nodes, and the connection of the control plane between the two nodes may be established based on a network path, possibly including a plurality of other nodes.

However, the network path carrying the connection of the data plane may be blocked sometimes, which may cause the network path to be not smooth, and may further cause the connection of the data plane to be disconnected, which may cause the data packet between the two nodes to be not normally transmitted.

In one possible scenario, the network path carrying the connection of the control plane between the two nodes is identical to the network path carrying the connection of the control data plane between the two nodes, so that in case of a network path blocking, both the connection of the control plane between the two nodes and the connection of the data plane are disconnected, resulting in an inability to normally transmit data messages between the two nodes.

In order to enable normal transmission of data messages between the two nodes, it is necessary to restore the connection of the data plane between the two nodes, but if necessary.

However, it takes a while to restore the connection of the data plane between the two nodes, which aggravates the affected extent of the transmission of the data message between the two nodes.

Thus, in order to reduce the affected extent of the transmission of data messages between two nodes as much as possible, referring to fig. 1, a flow diagram of a method of data message transmission in a network according to the present application is shown.

The network comprises a plurality of nodes, and each node comprises a component of a control plane and a component of a data plane.

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

The first node and the second node in the network are connected by a first data surface, and the first node and the second node can mutually transmit data messages based on the connection of the first data surface.

A connection having a first control plane between a first node in the network and a second node in the network, a connection of a data plane between the first node in the network and the second node in the network, etc. may be established based on the connection of the first control plane.

In the method, the first node is taken as an execution body to describe the flow of the method, but the method is not taken as a limitation on the protection scope of the application, and specifically, the method comprises the following steps:

In step S101, in case the connection of the first data plane is not broken, at least one second network path between the first node and the second node is detected from the components of the control plane of the first node, the second network path being different from the first network path carrying the connection of the first data plane.

In the present application, in general, the connection of the first data plane between the first node and the second node is connected, and the data packet can be transmitted between the first node and the second node based on the connection of the first data plane.

However, sometimes, in a possible case, a first network path between the first node and the second node may be blocked (for example, a network black hole, etc.), for example, a certain node in the first network path is down, so that the first network path between the first node and the second node is blocked, and if the first network path between the first node and the second node is blocked, the connection of the first data plane between the first node and the second node is disconnected.

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

The interruption of the transmission of the data packet is an undesirable phenomenon, so that the connection of the data plane between the first node and the second node can be recovered as soon as possible under the condition that the connection of the first data plane between the first node and the second node is disconnected, 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 be able to recover the connection of the data plane between the first node and the second node as soon as possible, in the present application, in case the connection of the first data plane is not broken, the connection of the second data plane between at least one first node and the second node may be additionally established as a backup, and it is necessary to make the first network path carrying the connection of the first data plane different from the second network path carrying the connection of the second data plane.

In this way, in the case that the first network path is blocked, and the connection of the first data surface is disconnected, if the second network path is not disconnected, the connection of the second data surface is available for connection, so that the data message between the first node and the second node can be continuously transmitted directly by means of the connection of the connected second data surface, so that the transmission of the data message between the first node and the second node can be quickly resumed.

In order to additionally establish the connection of the second data plane between the at least one first node and the second node as a backup, in the present application, in the case that the connection of the first data plane is not broken, the at least one second network path between the first node and the second node may be detected according to the components of the control plane of the first node, and then step S102 may be 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 based on the components 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 of the second network paths between the detected 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 each other second network path between the detected first node and the second node. And, the port numbers of the associated first nodes in the different second network paths are different and/or the port numbers of the associated second nodes are different, etc.

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

The same is true for each other second network path between the detected first node and the second node. Thereby enabling a connection to be established for 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 broken and the connection of at least one second data plane is not broken, according to the components of the data plane in the first node, 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 broken.

Wherein, through step S101 and step S102, a connection between the first node and the second node with a first data plane and a connection with at least one second data plane can be achieved.

In one case, the first node and the second node mutually transmit the data message 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 mutually transmit the data message based on the connection of the first data plane, however, if the connection of at least one second data plane is not disconnected, the first node and the second node can continuously mutually transmit the data message based on the connection of one second data plane, so that the data message to be transmitted between the first node and the second node can be switched to the connection transmission of the second data plane which is not disconnected according to the components of the data plane in the first node.

In the present 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.

If 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, and if the third network path is blocked, the second network path is blocked, which results in disconnection of both the connection of the second data plane and the connection of the first control plane, and since the connection of the first data plane is also disconnected, connection of the data plane which is not communicated between the first node and the second node is caused, and further, transmission of data messages between the first node and the second node is not possible.

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 required to be spent 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 message between the first node and the second node is further affected.

Therefore, in order to solve the above-mentioned problem, in another embodiment of the present application, the third network path carrying the connection of the first control plane is different from the second network path, for example, when the component of the control plane of the first node detects at least one second network path between the first node and the second node in step S101, the third network path may 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 carrying the connection of 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, it would result in the disconnection of the first control plane, but it would not necessarily result in the blocking of the second network path, i.e. it would not necessarily result in the disconnection of the second data plane.

Under the condition that the second network path is not blocked, the connection of the second data surface is not disconnected, namely the connection of the second data surface is communicated, the transmission of the data message can still be carried out between the first node and the second node based on the connection of the second data surface, the situation that the connection of the data surface which is not communicated between the first node and the second node due to the blocking of the third network path is avoided, and further the transmission of the data message cannot be carried out between the first node and the second node is avoided, and the influence on the transmission of the data message between the first node and the second node can be avoided.

Or in another embodiment of the present application, other available network paths between the first node and the second node, which are different from the second network path and the third network path, may be detected according to the component of the control plane of the first node, and connection of other control planes of the communication between the first node and the second node is established based on the detected other network paths, so as to backup the connection of the control plane.

Therefore, if the connection of the first control plane is disconnected, and the connection of the first data plane is disconnected and the connection of the second data plane is disconnected, the connection of the data plane which is not communicated between the first node and the second node is caused, and further, the transmission of the data message between the first node and the second node cannot be performed.

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

In this case, there is no connection of the data plane between the first node and the second node, so that transmission of the data packet between the first node and the second node cannot be performed, and therefore, connection of the data plane between the first node and the second node needs to be established in real time to resume transmission of the data packet between the first node and the second node.

In one example, if the connection of the first control plane is not broken, at least one fourth network path may be detected in real time between the first node and the second node according to the components of the control plane in the first node, and in the present application, the fourth network path to be detected is a connected network path but not a blocked network path, so 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 the at least one third data plane between the first node and the second node may be established according to the components 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, which is not described in detail herein. And switching the data message to be transmitted between the first node and the second node to the connection transmission of at least one third data plane according to the components of the data planes in the first node.

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

If 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, and if the third network path is blocked, the fourth network path is blocked, which results in disconnection of both the connection of the third data plane and the connection of the first control plane, and since the connection of the first data plane and the connection of the second data plane are also disconnected, there is no connection of the data plane between the first node and the second node, and further, transmission of data messages between the first node and the second node is disabled.

Therefore, in order to solve the above-mentioned problem, in another embodiment of the present application, the third network path carrying the connection of the first control plane is different from the fourth network path, for example, when the component according to the control plane of the first node detects at least one fourth network path between the first node and the second 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 carrying the connection of 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, this will result in a disconnection of the first control plane, but not necessarily in a blocking of the fourth network path, i.e. not necessarily in a disconnection of the third data plane.

Under the condition that the fourth network path is not blocked, the connection of the third data surface is not disconnected, namely the connection of the third data surface is communicated, the transmission of the data message can still be carried out between the first node and the second node based on the connection of the third data surface, the situation that the connection of the data surface which is not communicated between the first node and the second node due to the blocking of the third network path is avoided, and further the transmission of the data message cannot be carried out between the first node and the second node is avoided, and the influence on the transmission of the data message between the first node and the second node can be avoided.

Or in another embodiment of the present application, other available network paths between the first node and the second node, which are different from the fourth network path and the third network path, may be detected according to the component of the control plane of the first node, and connection of other control planes of the communication between the first node and the second node may be established based on the detected other network paths, so as to backup the connection of the control plane.

In this way, 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 data plane between the first node and the second node is not available, and further, the transmission of the data message between the first node and the second node cannot be performed, then the connection of the data plane between the first node and the second node can be restored directly according to the connection of the other connected control plane, so that the situation that the connection of the control plane between the first node and the second node needs to be restored in real time is avoided, 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 plane is avoided, so that the transmission efficiency of the data message 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 previously shown embodiments, in case of a possible disconnection of the first data plane between the first node and the second node, the connection of the second data plane between the first node and the second node established in advance is disconnected (for example, the connection of the second data plane is disconnected due to the second network path blocking), and the connection of the first control plane is also disconnected (for example, the connection of the first control plane is disconnected due to the third network path blocking).

However, in this case, there is no connection between the first node and the second node for the control plane, and in order to establish a connection between the first node and the second node for the data plane for communication to resume transmission of the data packet between the first node and the second node, it is necessary to resume the connection between the first node and the second node 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 detected in real time between the first node and the second node based on the components of the control plane in the first node.

In the present application, the fifth network path to be detected is a connected network path but not a blocked network path, so that the detected fifth network path may be different from the first network path, the second network path and the third network path, and then a connection of the second control plane between the first node and the second node may be established according to the components 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 components of the control plane in the first node, the connection of the second control plane and at least one fifth network path; the specific 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, which is not described in detail herein. And switching the data message to be transmitted between the first node and the second node to at least one connection transmission of a fourth data plane according to the components of the data plane in the first node.

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

If the fifth network path carrying the connection of the second control plane is the same as the fifth network path carrying the connection of the fourth data plane, if the fifth network path carrying the connection of the second control plane is blocked, the fifth network path carrying the connection of the fourth data plane is blocked, which results in disconnection of both the connection of the fourth data plane and the connection of the second control plane, and since the connection of the first data plane is also disconnected and the connection of the second data plane is also disconnected, connection of the data plane with no communication exists between the first node and the second node, and further, transmission of data messages between the first node and the second node is impossible.

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 required to be spent 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 message between the first node and the second node is further affected.

Therefore, in order to solve the above-mentioned problem, in another embodiment of the present application, there are at least two detected fifth network paths, 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 at least one fifth network path between the first node and the second node is detected by a component of the control plane of the first node, the other fifth network paths between the first node and the second node may be detected by bypassing the fifth network path carrying the connection of the second control plane, such that the detected fifth network path between the first node and the second node for establishing the connection of the data plane 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, this may result in a disconnection of the second control plane, but not necessarily in a blocking of the fifth network path carrying the connection of the fourth data plane, i.e. not necessarily in a disconnection of the fourth data plane.

In the case that the fifth network path 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 transmission of the data message can still be performed between the first node and the second node based on the connection of the fourth data plane, and the situation that the connection of the data plane which is not connected between the first node and the second node due to the blocking of the fifth network path carrying the connection of the second control plane, and further the transmission of the data message cannot be performed between the first node and the second node, is avoided.

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 the component of the control plane of the first node, and the connection of the other control plane of the communication between the first node and the second node may be established based on the detected other network paths, so as to backup the connection of the control plane.

In this way, if the connection of the second control plane is disconnected, the connection of the first data plane is disconnected, the second data plane is disconnected, and the fourth data plane is disconnected, so that the connection of the data plane between the first node and the second node is not available, and further, the transmission of the data message between the first node and the second node cannot be performed, then the connection of the data plane between the first node and the second node can be restored directly according to the connection of the other connected control planes, so that the situation that the connection of the control plane between the first node and the second node needs to be restored in real time is avoided, 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 plane 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.
