Description

Method, device, equipment and medium for dynamically establishing tunnel

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a method, an apparatus, a device, and a medium for dynamically establishing a tunnel.

Background

At present, different nodes of a virtualization layer are communicated with each other through a tunnel network card in an Overlay tunnel, when a communication requirement exists between a source address and a destination address, user data is forwarded through a virtual tunnel established between data center IP networks, namely, the virtualization layer adopts an Overlay protocol network, two virtual machines are directly connected with a router, a virtual link tunnel can be directly established for communication, and the connected router is called a tunnel terminal. The tunnel terminals in the same two layers need to establish virtual tunnels, and the source IP address and the destination IP address of each tunnel are communicated through the tunnel terminal address of the local virtual machine and the virtual tunnel terminal address of the target virtual machine.

However, in some Overlay scenes, tunnels cannot be dynamically established, interfaces of tunnels at two ends cannot be connected with each other, and dynamic establishment of tunnels needs to be realized in ways of manually changing codes and the like, so that advantages brought by network performance of OpenStack Overlay are greatly lost.

In summary, how to implement dynamic establishment of tunnels is a problem to be solved at present.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

At present, tunnels cannot be dynamically established in an Overlay scene, interfaces of the tunnels at two ends cannot be connected with each other, and the tunnels need to be dynamically established in a manner of manually changing codes and the like, so that the advantages brought by the network performance of the OpenStack Overlay are greatly lost. The Overlay is used as a common network type of OpenStack, and development of adaptation for supporting Overlay network design is important for establishing a tunnel. In the prior art, a tunnel is only used as an information receiving device and does not process tunnel receiving information, and if a tunnel terminal of a network node only supports notification of tunnel establishment or deployment modes and tunnel technologies of all nodes are different, the tunnel cannot be established. The control plane design process only reports the information through the message channel and informs other nodes of completing the establishment of the tunnel, but if the two nodes cannot be matched, the establishment of the tunnel cannot be completed. Therefore, the embodiment of the application discloses a method, a device, equipment and a medium for dynamically establishing a tunnel, which can realize the dynamic establishment of the tunnel.

Referring to fig. 1 and fig. 2, an embodiment of the present application discloses a method for dynamically establishing a tunnel, where the method includes:

step S11: and determining a target computing node of a tunnel to be established, and reporting the target computing node to a target network component so that the target network component establishes a corresponding tunnel port.

In this embodiment, a target computing node of a tunnel to be established is determined, and the target computing node is reported to a target network component, that is, the reporting of node information is realized. The target network component of the tunnel Overlay tunnel to be established is a neural Server, and the neural Server establishes a tunnel port corresponding to the target computing node. The Neutron Server side code mainly realizes the processing of information reported by nodes with different deployment modes, the drive mechanism receives the port reported node information, realizes the binding of the port and the updating of the port to the starting state, realizes the function of processing the reported information while monitoring the reported node information,

step S12: and binding the tunnel port with the target computing node through the target network component, broadcasting the target computing node, and monitoring the state change information of the tunnel port to determine whether to establish a tunnel.

In this embodiment, the target network component router Server binds the tunnel port and the target computing node, and monitors the state change information of the tunnel port to determine whether to establish a tunnel. It can be understood that, as shown in fig. 3, the Neutron Server has the capability of processing the binding information of the routing/gateway port, so that the binding information of the processing port can be newly added on the original basis, the original interface is called to perform the port host binding, and the port host binding is written into the database. In addition, the tunnel not only serves as an information receiving device, but also can process tunnel information, so that the nodes of the opposite end do not need to be matched with each other, only a request for establishing the tunnel needs to be sent, and the tunnel can process data of the opposite end to realize tunnel establishment. Optimizing the tunnel communication implementation mode is crucial to the receiving and sending processes of data packets, improving the data forwarding plane is crucial to the forwarding efficiency in the data processing process, and improving the packet processing process so as to better implement tunnel establishment and forwarding. In addition, the provided network interface transmits network data in two layers and three layers, and optimizes the functional defects of the data plane.

Further, in the monitoring of the state change information of the tunnel port to determine whether to establish the tunnel, the method further includes: and acquiring heartbeat packet information sent by the tunnel port at preset time intervals so as to judge whether a target computing node corresponding to the tunnel port is in an online state or not according to the heartbeat packet information. It can be understood that the neuron Server can establish a tunnel with other nodes after acquiring the computing node information and the port binding information, and in addition, the state change of the port needs to be monitored in the ETCD, any network-related operation two-layer function is optional, the port heartbeat packet message reporting needs to be realized, and whether the target computing node is in an online state or not can be refreshed at intervals. Reporting node state information to indicate that the service is running, then issuing the node state information to a route or gateway interface corresponding to the node, and binding a route or gateway port to a target computing node so as to realize the starting state of the port.

In addition, the above process of broadcasting the target computing node further includes: determining a target network where the tunnel port is located, and searching other target ports in a port available state in the target network; and acquiring the 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 the computing node information corresponding to the target ports is obtained. And then, the information of the computing nodes where the ports are located is notified to the reported computing nodes through a broadcast message, and the information of the computing nodes is broadcast to all the nodes.

Step S13: and if the tunnel is determined to be established, adding the tunnel port to a preset bridge, and setting the tunnel port to be in a port available state.

In this embodiment, if it is determined that a tunnel is established, the established tunnel port is inserted into the preset bridge, and the tunnel port is set to the port available state. In addition, the corresponding service information is searched in the database according to the host name scheduled to the computing node and the node type driven by the mechanism, and then whether the network type of the port is supported or not is deduced. And Neutron can monitor the state change of the port and bind the port to the host, the state of the port is set to be started after the binding is finished, and the establishment of the tunnel can be directly realized by two different nodes. There are two possibilities for port changes, one is port update and one is port delete, see in particular fig. 4. Therefore, the original Overlay scene tunnel mechanism is modified, so that the tunnel mechanism of the control plane is kept native, and only the data plane is changed. The problem that due to the differentiation of each node, the two ends of the tunnel cannot be matched, and then the tunnel can not be built is solved. The scheme of the application can realize the intercommunication among the computing nodes in the Overlay network.

It should be noted that, in the process of adding the tunnel port to the preset bridge, the method further includes: and determining horizontal division group numbers of other ports in the preset bridge, and configuring the tunnel port by using the horizontal division group numbers. It can be understood that, in order to avoid routing loops and accelerate route aggregation, when tunnel ports are added to bridges, they are also configured with the same and non-zero horizontal split group number, that is, the horizontal split group numbers of the rest of ports in the preset bridges are obtained, and the tunnel ports are configured by using the horizontal split group numbers, otherwise, the Overlay tunnel is completely meshed between servers, and flooding packets may circulate between servers with the same network segment. In addition, if the three tunnel endpoints have the requirement of mutual communication, the three tunnel endpoints do not need to establish VXLAN tunnels, and every two tunnels can be established.

Referring to the above tunnel establishment process, a connection is established for tunnels of different modes between nodes. If no two-layer tunnel communication requirement exists between the computing nodes, for example, the computing nodes do not have virtual machines, and the virtual machines do not have communication requirements, no tunnel needs to be established. The establishment of unnecessary tunnels is reduced, and the number of two-layer broadcast messages is reduced, so that the efficiency is improved. Specifically, the process of dynamically establishing the tunnel is as follows: when the computing node finds that the network card is inserted and identifies the network card as an interface for network management, calling a relative network component Neutron Server through a broadcast message calling method; after receiving the message, the Neutron Server calls an update state function to set the state of the port as a starting state, and calls all related drivers to synchronously update the port to the starting state before submitting the port; when the method for driving the update port state is used for processing, the update port number is synchronously called, other available ports of the same network with the update port number are searched according to the available port number in the state, then the node information of the port is notified to the reported computing node through the broadcast message, and the computing node information is broadcast to all nodes.

That is, the embodiment of the present application is mainly implemented by issuing each node synchronization and maintaining the data table through the plug-in. When the virtual machine created by the designated network is started, the virtual machine is dispatched to the computing node, and the computing related service of the node can call the interface of the created port of the network module, wait for the state of the port to become available, and further realize the dynamic establishment of the subsequent tunnel. That is, through the process of dynamically establishing the tunnel, the interconnection of the Overlay type virtual machines is completed for the user interface of the virtual host node, and the interface can provide service for the end similar to the DHCP. And creating a port interface synchronous cycle and calling all supported network mechanism methods to perform port binding, wherein the port state becomes available after the binding is successful. The network module needs to add a plug-in for tracking the state of the configured resource, when the port is created and bound to the host, the network module is used for tracking the configuration state of each port, and each node needs to complete the calling work before the port is converted into the available state. The original node needs to broadcast to all nodes and establish a tunnel, and after improvement, the broadcast is sent to a related agent and establishes connection only through a unicast encapsulation packet.

Therefore, the target computing node of the tunnel to be established is determined, and the target computing node is reported to the target network component, so that the target network component can establish a corresponding tunnel port; binding the tunnel port with the target computing node through the target network component, broadcasting the target computing node, and monitoring state change information of the tunnel port to determine whether to establish a tunnel; and if the tunnel is determined to be established, adding the tunnel port to a preset bridge, and setting the tunnel port to be in a port available state. Therefore, the target computing node of the tunnel to be established is determined, the target computing node is reported to the target network component, the corresponding tunnel port is established by the target network component, and then the tunnel port and the target computing node are bound; and then broadcasting the target computing node, monitoring state change information of the tunnel port to determine whether a tunnel needs to be established, if so, adding the tunnel port to a preset network, and setting the port to be in a port available state. The technical scheme realizes the dynamic establishment of the tunnel between the computing nodes and further realizes the intercommunication between different computing nodes.

Referring to fig. 5, the embodiment of the present application discloses a specific method for dynamically establishing a tunnel, and compared with the previous embodiment, the present embodiment further describes and optimizes the technical solution. The method specifically comprises the following steps:

step S21: and the computing node determines a target point of the tunnel to be established and reports the target computing node to the target network component so as to facilitate the target network component to establish a corresponding tunnel port.

Step S22: and binding the tunnel port with the target computing node through the target network component, and broadcasting the target computing node.

Step S23: and monitoring the state change information of the tunnel port to acquire the tunnel port number and the IP address of the remote computing node, and acquiring the currently established tunnel information from a preset database.

In this embodiment, monitoring the state change information of the tunnel port is specifically used in the ETCD listener, that is, a listener is specifically provided in this embodiment, and specifically, as shown in fig. 6, the listener is mainly designed for an Overlay tunnel and is configured to process the monitored change of the Overlay tunnel port and receive and process a message for creating the Overlay tunnel. And then acquiring the tunnel port number, the host name and the port IP from the ETCD listener so as to acquire the IP address of the remote computing node, namely the remote host IP. And then acquiring the current tunnel information to be established from a preset database. It should be noted that, it is necessary to further determine whether the host name is the host name of the local computer, and if so, no processing is needed; and judging whether the tunnel port number has a routing port of the same opposite end on the node, and if not, processing is not needed.

Step S24: and judging whether a tunnel corresponding to the tunnel port number and the IP address exists at present or not based on the tunnel information, and if not, determining to establish the tunnel between the target computing node and the far-end computing node.

In this embodiment, it is determined whether a tunnel corresponding to the tunnel port number and the IP address, specifically, an interface of the call node, exists at present based on the tunnel information, and acquires all tunnels that have been created at present, and determines whether a tunnel corresponding to the tunnel port number + the remote host IP exists, and if not, determines to establish an overlay tunnel between the target computing node and the remote computing node.

Step S25: and if the tunnel is determined to be established, adding the tunnel port to a preset bridge, and setting the tunnel port to be in a port available state.

In this embodiment, if it is determined that a tunnel is to be established, the tunnel information including the tunnel port number and the IP address of the remote computing node is stored in the preset database. Specifically, tunnel port number + host name is used as a key value, and a remote host IP + IP address + MAC is used as a vlaue value and stored in a database, so that all created tunnels can be acquired later. That is, the present design is directed to providing functionality for creating an overlay tunnel port that may be added to a bridge as a bridge port to participate in layer two forwarding. The tunnel is dynamically established through the design, the control plane keeps native, only the data plane is changed, the monitoring port becomes available time, the monitoring port is sent to other nodes needing to establish the tunnel through the ETCD to be processed, and the tunnel intercommunication with other nodes is realized.

In addition, the method further comprises: when a tunnel deleting command is acquired, screening target tunnel information corresponding to a tunnel to be deleted from the preset database; and extracting the IP address of the remote computing node in the target tunnel information, and executing deletion operation on the target tunnel information. It can be understood that, if the tunnel deletion command is obtained, the target tunnel information corresponding to the tunnel to be deleted is screened from the preset database, the remote host IP is extracted, and the deletion operation is executed. That is, when a tunnel or a related interface needs to be deleted, a pair of key-vlaue values is obtained from the ETCD database, the remote host IP is taken out, if only one piece of data needing to be deleted remains in the cache, the invocation is performed to delete the Overlay tunnel, and if a plurality of pieces of data exist, only the corresponding cache is deleted.

For more specific processing procedures of the steps S21 and S22, reference may be made to corresponding contents disclosed in the foregoing embodiments, and details are not repeated here.

As can be seen, the computation node of the embodiment of the present application determines a target point of a tunnel to be established, and reports the target computation node to a target network component, so that the target network component establishes a corresponding tunnel port; binding the tunnel port with the target computing node through the target network component, and broadcasting the target computing node; monitoring state change information of the tunnel port to acquire a tunnel port number and an IP address of a remote computing node, and acquiring currently established tunnel information from a preset database; monitoring state change information of the tunnel port to acquire a tunnel port number and an IP address of a remote computing node, and acquiring currently established tunnel information from a preset database; and if the tunnel is determined to be established, adding the tunnel port to a preset bridge, and setting the tunnel port to be in a port available state. Therefore, in the embodiment, an ETCD listener is arranged, mainly aiming at the design of an Overlay tunnel, and is used for processing the monitored change of an Overlay tunnel port, and then acquiring a tunnel port number, a host name and a port IP from the ETCD listener, so as to acquire the IP address of a remote computing node, namely a remote host IP, and then acquiring all the currently-created tunnels, judging whether the tunnel corresponding to the tunnel port number + the remote host IP exists, if not, determining to establish the Overlay tunnel between a target computing node and the remote computing node, and storing tunnel information including the tunnel port number and the IP address of the remote computing node into a preset database, so as to realize the dynamic establishment of the tunnel between the computing nodes. According to the scheme, after the tunnel is dynamically established in the Overlay scene, even if the opposite end nodes cannot be matched with each other to establish the tunnel in the Overlay network type, different deployment modes and different nodes, the tunnel can be dynamically established through the tunnel logic and the tunnel mechanism, and the tunnel can be dynamically established under the Overlay network type, such as network creation/deletion, router creation/deletion, interface addition/deletion for the router and the like.
