Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, device, equipment and medium for dynamically establishing a tunnel. Background Art

[0002] At present, different nodes in the virtualization layer communicate with each other through the tunnel network card in the Overlay tunnel. When there is a communication demand between the source address and the destination address, the user data is forwarded through a virtual tunnel created between the IP networks of the data center. That is, the virtualization layer adopts the Overlay protocol network. The routers directly connected to the two virtual machines can directly establish a virtual link tunnel for communication. The connected routers are called tunnel terminals. All tunnel terminals in the same large second layer need to establish virtual tunnels. The source IP address and destination IP address of each tunnel communicate through the tunnel terminal address of the local virtual machine and the virtual tunnel terminal address of the target virtual machine.

[0003] However, there are currently some Overlay scenarios where tunnels cannot be established dynamically, and the tunnel interfaces at both ends cannot be connected to each other. Instead, the dynamic establishment of tunnels needs to be achieved through manual code modification, which greatly loses the advantages brought by the OpenStack Overlay network performance. As a commonly used network type in OpenStack, it is crucial to develop Overlay network design that supports tunnel establishment. In the prior art, the tunnel only serves as an information receiving device and does not process tunnel reception information. If the tunnel terminal of the network node only supports notification of tunnel establishment, or the deployment mode and tunnel technology of each node are different, the tunnel cannot be established. The control plane design process only reports information through the message channel to notify other nodes to complete the tunnel establishment, but if the two nodes cannot match, the tunnel establishment cannot be completed.

[0004] In summary, how to achieve dynamic tunnel establishment is a problem that needs to be solved at present. Summary of the invention

[0018] Optionally, the process of monitoring the status change information of the tunnel port to determine whether to establish a tunnel further includes:

[0019] The heartbeat packet information sent by the tunnel port at every preset time interval is obtained, so as to determine whether the target computing node corresponding to the tunnel port is in an online state according to the heartbeat packet information.

[0020] Optionally, the process of adding the tunnel port to the preset bridge further includes:

[0021] The split horizon group numbers of the remaining ports in the preset bridge are determined, and the tunnel ports are configured using the split horizon group numbers.

[0022] Optionally, the process of broadcasting to the target computing node further includes:

[0023] Determine the target network where the tunnel port is located, and search for other target ports in the target network that are in a port available state;

[0024] Obtain computing node information corresponding to the target port.

[0028] A monitoring module, used for monitoring the status change information of the tunnel port to determine whether to establish a tunnel;

[0029] The tunnel establishing module is used to add the tunnel port to the preset bridge if it is determined to establish the tunnel, and set the tunnel port to the port available state.

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] At present, there are some Overlay scenarios where tunnels cannot be established dynamically, and the tunnel interfaces at both ends cannot be connected to each other. Instead, it is necessary to manually modify the code to dynamically establish the tunnel, which greatly loses the advantages brought by the OpenStack Overlay network performance. As a commonly used network type in OpenStack, it is crucial to develop Overlay network design that supports the establishment of tunnels. In the prior art, the tunnel is only used as an information receiving device and does not process the tunnel reception information. If the tunnel terminal of the network node only supports notification of tunnel establishment, or the deployment mode and tunnel technology of each node are different, the tunnel cannot be established. The control plane design process only reports the information through the message channel to notify other nodes to complete the tunnel establishment, but if the two nodes cannot match, the tunnel establishment cannot be completed. To this end, the embodiments of the present application disclose a method, device, equipment and medium for dynamically establishing a tunnel, which can realize the dynamic establishment of a tunnel.

[0046] See also Figure 1 and Figure 2 As shown, the embodiment of the present application discloses a method for dynamically establishing a tunnel, the method comprising:

[0047] Step S11: determine a target computing node for a tunnel to be established, and report the target computing node to a target network component so that the target network component creates a corresponding tunnel port.

[0048] In this embodiment, the target computing node of the tunnel to be established is determined, and the target computing node is reported to the target network component, that is, the reporting of node information is realized. Among them, the tunnel to be established is an Overlay tunnel, and the target network component is specifically Neutorn Server. Neutorn Server will create a tunnel port corresponding to the target computing node. The NeutronServer side code mainly realizes the processing of information reported by nodes in different deployment modes, the driving mechanism receives the port reported node information, and realizes port binding and port update to the enabled state. While monitoring the reported node information, it realizes the function of processing the reported information.

[0049] Step S12: Bind the tunnel port to the target computing node through the target network component, broadcast to the target computing node, and monitor the status change information of the tunnel port to determine whether to establish a tunnel.

[0050] In this embodiment, the target network component Neutorn Server binds the tunnel port to the target computing node and monitors the status change information of the tunnel port to determine whether to establish a tunnel. Figure 3 As shown, Neutron Server has the ability to process routing / gateway port binding information. Therefore, on the basis of the original, it can add processing port binding messages, call the original interface to perform port host binding, and write it to the database. In addition, the tunnel is not only an information receiving device, but also can process tunnel information. Therefore, there is no need for the peer nodes to match each other. It is only necessary to send a request to establish a tunnel. The tunnel will process the peer data to establish the tunnel. Optimizing the tunnel communication implementation method is crucial for the data packet sending and receiving process. Improving the data forwarding plane is crucial for the forwarding efficiency in the data processing process. Improving its packet processing process is crucial to better realize tunnel establishment and forwarding. In addition, the network interface provided performs layer 2 and layer 3 forwarding of network data, and optimizes the functional defects of the data plane.

[0051] Furthermore, in the process of monitoring the status change information of the tunnel port to determine whether to establish a tunnel, it also includes: obtaining the heartbeat packet information sent by the tunnel port at preset time intervals, so as to determine whether the target computing node corresponding to the tunnel port is online according to the heartbeat packet information. It is understandable that NeutornServer can establish a tunnel with other nodes only after obtaining the computing node information and port binding information. In addition, it is necessary to monitor the port status changes in ETCD. Any network-related operation layer 2 function is required. It is necessary to implement port heartbeat packet message reporting, and it is possible to refresh whether the target computing node is online every once in a while. Reporting node status information indicates that the service is running, and then it is sent to the routing or gateway interface corresponding to the node, and the routing or gateway port is bound to the target computing node, thereby realizing the enabled state of the port.

[0052] In addition, the above-mentioned process of broadcasting the target computing node also includes: determining the target network where the tunnel port is located, and searching for other target ports in the target network that are in a port available state; and obtaining computing node information corresponding to the target port. That is, by determining the target network where the tunnel port is located, the remaining available target ports can be searched in the network, and computing node information corresponding to the target port can be obtained. Then, the computing node information where these ports are located is notified to the reporting computing node through a broadcast message, and the computing node information is broadcast to all nodes at the same time.

[0053] Step S13: If it is determined to establish a tunnel, the tunnel port is added to the preset bridge, and the tunnel port is set to a port available state.

[0054] In this embodiment, if it is determined to establish a tunnel, the created tunnel port will be inserted into the preset bridge, and the tunnel port will be set to the port available state. In addition, the corresponding service information is searched in the database based on the host name of the computing node scheduled and the node type driven by the mechanism, and then it is inferred whether the network type where the port is located is supported. In addition, Neutron can monitor changes in port status and bind the port to the host. After the binding is completed, the port status is set to enabled, and two different nodes can directly establish a tunnel. There are two possibilities for port changes, one is port update and the other is port deletion. Please refer to the specific details. Figure 4 As shown in . It can be seen that this application modifies the original Overlay scenario tunnel mechanism so that the control plane tunnel mechanism remains native and only changes the data plane. This avoids the problem of being unable to match the two ends of the tunnel and thus unable to complete the tunnel establishment due to the differences between the nodes. The solution of this application can achieve intercommunication between computing nodes in the Overlay network.

[0055] It should be pointed out that the above process of adding the tunnel port to the preset bridge also includes: determining the horizontal segmentation group number of the remaining ports in the preset bridge, and configuring the tunnel port using the horizontal segmentation group number. It is understandable that in order to avoid routing loops and speed up routing convergence, it is also necessary to configure the same and non-zero horizontal segmentation group number for the tunnel ports when adding them to the bridge, that is, to obtain the horizontal segmentation group number of the remaining ports in the preset bridge, and use the horizontal segmentation group number to configure the tunnel port. Otherwise, the Overlay tunnel is fully meshed between the servers, and flooding data packets may circulate between servers with the same network segment. In addition, if the three tunnel endpoints have the need to communicate with each other, there is no need for all three to establish VXLAN tunnels with each other, and tunnels can be established two by two.

[0056] Referring to the above tunnel establishment process, in order to achieve different modes of tunnel establishment connection between nodes. If there is no Layer 2 tunnel communication demand between computing nodes, for example, there is no virtual machine in this computing node and the virtual machine has no communication demand, then there is no need to establish a tunnel. Reduce the establishment of unnecessary tunnels and reduce the number of Layer 2 broadcast messages to improve efficiency. Specifically, the process of dynamically establishing a tunnel is as follows: when the computing node finds that a network card is inserted and identifies it as a network management interface, it calls the relevant network component Neutron Server through the broadcast message call method; after receiving the message, Neutron Server will call the update status function to set the port status to the enabled state, and will call all related drivers to synchronize and update to the enabled state before submission; when the driver updates the port status method, it synchronously calls the update port number, and according to the available port number, finds other available ports in the same network as this port, and then notifies the reporting computing node of the node information through the broadcast message, and broadcasts the computing node information to all nodes at the same time.

[0057] That is, the embodiment of the present application is mainly implemented by sending each node synchronization and maintaining the data table through the plug-in. When the virtual machine created by the specified network is started, the virtual machine is scheduled to the computing node, and the computing-related service of the node will call the interface of the network module to create the port, waiting for the port status to become available, thereby realizing the dynamic establishment of the subsequent tunnel. That is, through the process of dynamically establishing the tunnel, the virtual machines of the Overlay type are connected to each other, which is used for the user interface of the virtual host node. This interface can provide services similar to the DHCP end. The port interface is created to synchronously call all supported network mechanism methods in a loop to bind the port. The port status becomes available only after the binding is successful. The network module needs to add a plug-in to track the configuration resource status. When the port is created and bound to the host, the network module is used to track the configuration status of each port. Before it becomes available, each node needs to complete the call. The original node needs to broadcast to all nodes and establish a tunnel. After the improvement, the broadcast is only sent to the relevant agent through a unicast encapsulation packet and a connection is established.

[0058] It can be seen that the present application determines the target computing node to be established for the tunnel, and reports the target computing node to the target network component so that the target network component creates a corresponding tunnel port; the tunnel port is bound to the target computing node through the target network component, and the target computing node is broadcast, and the state change information of the tunnel port is monitored to determine whether to establish a tunnel; if it is determined to establish a tunnel, the tunnel port is added to the preset bridge, and the tunnel port is set to the port available state. It can be seen that the present application first determines the target computing node to be established for the tunnel, and reports the target computing node to the target network component, and the target network component creates the corresponding tunnel port, and then binds the tunnel port to the target computing node; then broadcasts the target computing node, and monitors the state change information of the tunnel port to determine whether a tunnel needs to be established. If established, the tunnel port is added to the preset network, and the port is set to the port available state. The above technical solution realizes the dynamic establishment of tunnels between computing nodes, and further realizes the intercommunication between different computing nodes.

[0059] See also Figure 5 As shown, the embodiment of the present application discloses a specific method for dynamically establishing a tunnel. Compared with the previous embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, it includes:

[0060] Step S21: The computing node determines the target point of the tunnel to be established, and reports the target computing node to the target network component so that the target network component creates a corresponding tunnel port.

[0061] Step S22: Bind the tunnel port to the target computing node through the target network component, and broadcast to the target computing node.

[0062] Step S23: monitor the status change information of the tunnel port to obtain the tunnel port number and the IP address of the remote computing node, and obtain the currently established tunnel information from a preset database.

[0063] In this embodiment, the state change information of the monitoring tunnel port is specifically used in the ETCD monitor, that is, this embodiment specifically sets a monitor, as shown in the following example. Figure 6As shown in , it is mainly designed for Overlay tunnels, and is used to process the monitored Overlay tunnel port changes, as well as receive and process messages to create overlay tunnels. Then, the tunnel port number, host name, and port IP are obtained from the ETCD listener to obtain the IP address of the remote computing node, that is, the remote host IP. Then, the currently established tunnel information is obtained from the preset database. It should be noted that it is necessary to further determine whether it is the host name of the local machine. If so, no processing is required; determine whether the tunnel port number has the same routing port on the opposite end on the node. If not, no processing is required.

[0064] Step S24: based on the tunnel information, determine whether there is currently a tunnel corresponding to the tunnel port number and the IP address; if not, determine to establish a tunnel between the target computing node and the remote computing node.

[0065] In this embodiment, based on the tunnel information, it is determined whether there is a tunnel corresponding to the tunnel port number and IP address. Specifically, the interface of the calling node is used to obtain all the tunnels that have been created, and it is determined whether the tunnel corresponding to the tunnel port number + remote host IP exists. If not, it is determined to establish an overlay tunnel between the target computing node and the remote computing node.

[0066] Step S25: If it is determined to establish a tunnel, the tunnel port is added to the preset bridge, and the tunnel port is set to a port available state.

[0067] In this embodiment, if it is determined to establish a tunnel, the tunnel information including the tunnel port number and the IP address of the remote computing node is stored in the preset database. Specifically, the tunnel port number + host name is used as the key value, and the remote host IP + IP address + MAC is used as the vlaue value, which is stored in the database to facilitate the acquisition of all tunnels that have been created in the future. That is, the design of the present invention is intended to provide the function of creating an overlay tunnel port, which can be added to the bridge as a bridge port to participate in Layer 2 forwarding. Through the above design, a tunnel is dynamically established, the control plane remains native, only the data plane is changed, the listening port becomes available, and it is sent to other nodes that need to establish tunnels through ETCD for processing, so as to achieve tunnel intercommunication with other nodes.

[0068] In addition, the above method also includes: when a tunnel deletion command is obtained, the target tunnel information corresponding to the tunnel to be deleted is filtered out from the preset database; the IP address of the remote computing node in the target tunnel information is extracted, and the deletion operation is performed on the target tunnel information. It can be understood that if a tunnel deletion command is obtained, the target tunnel information corresponding to the tunnel to be deleted is filtered out from the preset database, the remote host IP is extracted, and the deletion operation is performed. That is, when the tunnel or related interface needs to be deleted, a pair of key-vlaue values ​​is obtained from the ETCD database, and the remote host IP is taken out. If there is only one piece of data to be deleted in the cache, a call to delete the Overlay tunnel is executed. If there are multiple pieces of data, only the corresponding cache is deleted.

[0069] For more specific processing procedures of the above steps S21 and S22, reference may be made to the corresponding contents disclosed in the above embodiments, which will not be described in detail here.

[0070] It can be seen that the computing node of the embodiment of the present application determines the target point of the tunnel to be established, and reports the target computing node to the target network component so that the target network component creates a corresponding tunnel port; binds the tunnel port to the target computing node through the target network component, and broadcasts the target computing node; monitors the status change information of the tunnel port to obtain the tunnel port number and the IP address of the remote computing node, and obtains the currently established tunnel information from the preset database; monitors the status change information of the tunnel port to obtain the tunnel port number and the IP address of the remote computing node, and obtains the currently established tunnel information from the preset database; if it is determined to establish a tunnel, the tunnel port is added to the preset bridge, and the tunnel port is set to the port available state. It can be seen that this embodiment sets an ETCD listener, which is mainly designed for Overlay tunnels, and is used to process the monitored Overlay tunnel port changes, and then obtains the tunnel port number, host name and port IP from the ETCD listener, thereby obtaining the IP address of the remote computing node, that is, the remote host IP, and then obtains all the tunnels that have been created, and determines whether the tunnel corresponding to the tunnel port number + remote host IP exists. If not, it is determined to establish an overlay tunnel between the target computing node and the remote computing node, and the tunnel information including the tunnel port number and the IP address of the remote computing node is stored in the preset database, thereby realizing the dynamic establishment of tunnels between computing nodes. After the above scheme realizes the process of dynamically establishing tunnels in the Overlay scenario, it can be realized under the Overlay network type, different deployment modes, and different nodes. Even if the peer nodes cannot match each other to establish tunnels, the tunnel logic and tunnel mechanism of the present invention can be used to realize dynamic tunnel establishment, which is supported under the Overlay network type, such as creating / deleting networks, creating / deleting routers, adding / deleting interfaces to routers, etc., and intercommunication can be achieved through dynamic tunnel establishment.

[0075] The tunnel establishing module 14 is used to add the tunnel port to the preset bridge if it is determined to establish the tunnel, and set the tunnel port to a port available state.

[0076] It can be seen that the present application determines the target computing node to be established for the tunnel, and reports the target computing node to the target network component so that the target network component creates a corresponding tunnel port; the tunnel port is bound to the target computing node through the target network component, and the target computing node is broadcast, and the state change information of the tunnel port is monitored to determine whether to establish a tunnel; if it is determined to establish a tunnel, the tunnel port is added to the preset bridge, and the tunnel port is set to the port available state.
