Abstract
The application is applicable to the technical field of networks, and particularly discloses an information release control method, device, equipment and a computer readable storage medium for a virtual tunnel endpoint.
Description
Technical Field
The present invention relates to the field of network technologies, and in particular, to a method, an apparatus, a device, and a computer readable storage medium for controlling information release of a virtual tunnel endpoint.
Background
The original implementation scheme of the virtual extension local area network (Virtual Extensible Local Area Network, VXLAN) has no control plane, and the discovery and host information learning of the virtual tunnel endpoint (Virtual Tunnel End Point, VTEP) are carried out through the flow flooding of the data plane. The host information includes an IP address, a MAC (Media Access Control Address) address, a VXLAN network identifier VNI, a gateway VTEP IP address, etc., where the host mainly refers to a virtual machine (a physical machine where the virtual machine is located) directly connected to the virtual tunnel endpoint. Because of the lack of a control plane, each virtual tunnel endpoint needs to send a large amount of data to complete the interaction of host information with other virtual tunnel endpoints, and the large amount of data occupies the data transmission channel, so that a data center network has a lot of flooding traffic.
To solve this problem, the virtual extended lan introduces an ethernet virtual private network (Ethernet Virtual Private Network, EVPN) as a control plane, and implements the characteristics of automatic discovery of virtual tunnel endpoints, mutual advertisement of host information, and the like by exchanging border gateway protocol ethernet virtual private network (Border Gateway Protocol Ethernet Virtual Private Network, BGP EVPN) routes between virtual tunnel endpoints, thereby avoiding unnecessary data traffic flooding.
The ethernet virtual private network is a virtual private network (Virtual Private Network, VPN) technology for data center large two-layer network interconnection. The EVPN technology adopts a mechanism similar to BGP/MPLS IP VPN, defines new network layer reachability information (Network Layer Reachability Information, NLRI) which is Ethernet virtual private network layer reachability information EVPN NLRI on the basis of border gateway protocols (Border Gateway Protocol, BGP), and defines 5 new BGP EVPN route types for address learning and release between different stations of the EVPN network. Wherein BGP EVPN type2 type routing can be used to pass host MAC addresses and IP addresses. When the virtual machine is on-line, the virtual tunnel endpoint connected with the virtual machine (the physical machine) issues a type2 information update message BGP update to all virtual tunnel endpoints with border gateway protocol neighbor relation based on the border gateway protocol.
However, if a certain virtual machine is frequently connected to the network, disconnected from the network, or continuously drifted between different virtual tunnel endpoints due to faults or other reasons, the virtual tunnel endpoint connected to the virtual machine (the physical machine where the virtual machine is located) frequently issues the information update message BGP update, so that a large amount of information update messages BGP update exist in the network, which wastes a large amount of bandwidth resources, and meanwhile, causes instability of the network and affects normal service.

Detailed Description
The core of the application is to provide a method, a device, equipment and a computer readable storage medium for controlling information release of a virtual tunnel endpoint, which are used for solving the problems that a large amount of information update messages exist in a network due to frequent change of the connection state of a virtual machine, so that a large amount of information update messages exist in the network, thereby wasting bandwidth resources and affecting services.
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Example 1
Fig. 1 is a flowchart of an information release control method of a virtual tunnel endpoint according to an embodiment of the present application; fig. 2 is a connection schematic diagram of a monitoring server according to an embodiment of the present application.
As shown in fig. 1, the information release control method for a virtual tunnel endpoint provided in the embodiment of the present application includes:
s101: and when a state change event occurs in a target virtual machine connected with the target virtual tunnel endpoint, acquiring historical state change data of the target virtual machine.
S102: and determining the connection state change frequency parameter of the target virtual machine according to the historical state change data.
S103: and if the connection state change frequency degree parameter of the target virtual machine accords with the preset state change frequency standard, prohibiting the target virtual tunnel endpoint from issuing a state update message of the target virtual machine to the border gateway protocol neighbor node.
S104: and if the connection state change frequency degree parameter of the target virtual machine does not accord with the state change frequency standard, allowing the target virtual tunnel endpoint to issue a state update message of the target virtual machine to the border gateway protocol neighbor node.
The three modes of the virtual tunnel endpoint (Virtual Tunnel End Point, VTEP), the virtual extended lan (Virtual Extensible Local Area Network, VXLAN) gateway, and VXLAN IP gateway may be virtual switches or physical switches. In this application, for convenience of description, a virtual tunnel endpoint and a target virtual tunnel endpoint refer to a switch (switch) that implements a virtual tunnel endpoint function.
Host information such as MAC address, IP address, etc. of hosts is transferred between virtual tunnel endpoints in an ethernet virtual private network (Ethernet Virtual Private Network, EVPN) through a border gateway protocol (Border Gateway Protocol, BGP) type2 route. In the prior art, after a virtual machine is on line, a virtual tunnel endpoint connected with a physical machine where the virtual machine is located will issue a type2 type information update message BGP update to all virtual tunnel endpoints having a border gateway protocol neighbor relation. If a certain virtual machine frequently goes up and down due to faults or other reasons or continuously drifts among different virtual tunnel endpoints, the corresponding virtual tunnel endpoint continuously issues information update messages (including BGP notification of the virtual machine going up and revocation messages of the virtual machine going down), so that a chain reaction is triggered, all virtual tunnel endpoints in a cluster where the virtual tunnel endpoint is located can repeat the same actions, issue BGP notification and revocation messages, waste a large amount of bandwidth resources, and meanwhile, cause unstable network and influence normal service. There is no reliable solution for frequent oscillation drift of hosts in ethernet virtual private networks.
The information release control method of the virtual tunnel endpoint aims at the problem of frequent oscillation drift of the host in the Ethernet virtual private network scene, and achieves the scheme of preventing network oscillation.
As shown in fig. 2, virtual tunnel endpoints in the ethernet virtual private network are interconnected two by two, and on this basis, each virtual tunnel endpoint may be arranged into a tree structure for data management, that is, each virtual tunnel endpoint is divided into a Spine node (Spine) and Leaf nodes (Leaf 1, leaf 2), and in general, hosts (Host 1, host1', host 2) are connected to the virtual tunnel endpoint as the Leaf nodes, one virtual tunnel endpoint may be connected to multiple hosts, and one Host may run multiple Virtual Machines (VMs). Frequent changes in the connection state of the virtual machine to the virtual tunnel endpoint are more likely to be caused by disconnection between the host and the virtual tunnel endpoint, and may also be caused by failure of the virtual machine itself. The embodiment of the application mainly focuses on the connection state between the virtual machine and the virtual tunnel endpoint, and does not focus on the data structure of the virtual tunnel endpoint. That is, as shown in fig. 2, the information release control method of the virtual tunnel endpoint provided in the embodiment of the present application may be applied to a monitoring server, where the monitoring server is a server connected to each virtual tunnel endpoint in a cluster where a target virtual tunnel endpoint is located. In general, in addition to virtual tunnel endpoints, a plurality of servers exist in a data network cluster, the servers have higher performance, and originally have a connection relationship with each virtual tunnel endpoint, and one or more servers respectively connected with each virtual tunnel endpoint in the cluster are selected as monitoring servers, so that information release control of the highly available virtual tunnel endpoints can be realized.
In consideration of possible connection interruption between the virtual tunnel endpoint and the monitoring server, in addition to using a plurality of servers as the monitoring server to improve availability, the information release control method for the virtual tunnel endpoint provided by the embodiment of the application may further include: and pre-agreeing feedback time with each virtual tunnel endpoint, so that when the target virtual tunnel endpoint does not receive the connection state change frequent degree parameter of the target virtual machine in the feedback time after reporting the state change event, the issuing strategy of the state update message of the target virtual machine is determined according to the latest connection state change frequent degree parameter of the target virtual machine.
Specifically, different feedback time can be agreed between different virtual tunnel endpoints and the monitoring server, the monitoring server manages feedback time of each virtual tunnel endpoint and historical state change data of each virtual machine, and each virtual tunnel endpoint manages virtual machines connected with the virtual tunnel endpoint and feedback time agreed between the virtual tunnel endpoint and the monitoring server. After the target virtual tunnel endpoint monitors the local online action or the local offline action of the target virtual machine, reporting the online action or the local offline action of the target virtual machine to the monitoring server, and waiting for a connection state change frequency parameter fed back by the monitoring server or a release strategy of a state update message of the target virtual machine. If the feedback time is exceeded and no message fed back by the monitoring server is received, disconnection from the monitoring server is determined, and at the moment, the virtual tunnel endpoint can temporarily adopt the latest connection state change frequency degree parameter of the target virtual machine stored locally to determine the release strategy of the state update message of the target virtual machine or execute the release strategy of the latest state update message of the target virtual machine stored locally.
In addition, the virtual tunnel endpoint can also adopt a heartbeat mechanism to monitor the connection state between the virtual tunnel endpoint and the monitoring server in real time, and directly adopts the latest connection state change frequency degree parameter of the target virtual machine stored locally to determine the release strategy of the state update message of the target virtual machine or execute the latest release strategy of the state update message of the target virtual machine stored locally when the online or offline action of the target virtual machine is monitored and the monitoring server cannot be connected.
When the monitoring server is set, the target virtual tunnel endpoint may report a state change event of the target virtual machine to the monitoring server based on the routing of the border gateway protocol type 2.
Or, the information release control method of the virtual tunnel endpoint provided by the embodiment of the application can also be applied to the virtual tunnel endpoint, namely, the virtual tunnel endpoint automatically determines the connection state change frequency degree of the target virtual machine and formulates a release strategy of the state update message of the target virtual machine after receiving the state change event of the target virtual machine connected with the virtual tunnel endpoint. The performance of the virtual tunnel endpoint (switch) is poorer than that of the server, but the time for communicating with the monitoring server can be saved, and information delay caused by unstable connection state between the virtual tunnel endpoint and the monitoring server can be avoided. However, the disadvantage of this scheme is that the virtual tunnel endpoint is not easy to determine that the target virtual machine frequently drifts between different virtual tunnel endpoints, and needs to interact with other virtual tunnel endpoints before determining.
In addition, the information release control method of the virtual tunnel endpoint provided by the embodiment of the application can be further applied to part of virtual tunnel endpoints in a cluster and used for managing information release strategies of all virtual tunnel endpoints, and after the target virtual tunnel endpoint monitors that a state change event occurs in a target virtual machine connected with the target virtual tunnel endpoint, the target virtual tunnel endpoint reports the information release strategies of state update messages of the target virtual machine for realizing control.
Whether applied to a monitoring server or a virtual tunnel endpoint, the information release control method of the virtual tunnel endpoint provided by the embodiment of the application needs to preset a calculation mode of a connection state change frequency parameter and determine a state change frequency standard. The calculation mode of the connection state change frequent degree parameter and the state change frequent standard aim at quantitatively planning whether the virtual machine connected with the virtual tunnel endpoint frequently generates the connection state change or not, and then the determination of the calculation mode of the connection state change frequent degree parameter and the determination of the state change frequent degree standard can be formulated and replaced in advance by a network administrator according to the busyness degree of the data cluster, and the calculation relation between the two parameters and the busyness degree parameter can be preset, so that the cluster can be formulated and replaced automatically.
Through the above-mentioned alternative scheme, oscillation suppression and drift suppression can be performed on the information update message issued by the virtual tunnel endpoint by formulating the connection state change frequent degree parameter and the state change frequent standard. And when the situation that the connection state is not changed frequently exists in the target virtual machine is quantitatively determined, the monitoring server or the target virtual tunnel endpoint can flood the state update message of the target virtual machine based on the routing of the type2 border gateway protocol so as to synchronize to each virtual tunnel endpoint in the cluster.
According to the information release control method of the virtual tunnel endpoint, after a state change event occurs in a target virtual machine connected with the target virtual tunnel endpoint, the target virtual tunnel endpoint does not release a state update message of the target virtual machine, but waits for a connection state change frequent degree parameter of a fixed target virtual machine determined according to historical state change data of the target virtual machine, the connection state change frequent degree parameter of the target virtual machine is compared with a preset state change frequent standard, whether the situation of frequent change of the connection state of the target virtual machine exists or not is determined in a quantitative mode, the target virtual tunnel endpoint is forbidden to release the state update message of the target virtual machine to a boundary gateway protocol neighbor node when the situation exists, and the target virtual tunnel endpoint is allowed to release the state update message when the situation does not exist, so that the problems that a large amount of information update messages exist in a network and bandwidth resources are wasted and service influence are effectively relieved due to frequent change of the connection state of the virtual machine.
Example two
Based on the above embodiment, in order to implement oscillation suppression of a host frequent oscillation event, such as frequent online and offline of a target virtual machine on a target virtual tunnel endpoint, in the information release control method of a virtual tunnel endpoint provided in the embodiment of the present application, S102: determining the connection state change frequency parameter of the target virtual machine according to the historical state change data specifically may include:
when the target virtual machine performs one online action or one offline action on the target virtual tunnel endpoint, adding one to a first punishment coefficient corresponding to the target virtual machine;
if the target virtual machine does not have the online action or the offline action after the first attenuation period is spaced, subtracting one from a first penalty coefficient corresponding to the target virtual machine;
wherein the first penalty coefficient is an integer not less than zero.
In the implementation, the first penalty coefficient is used as a connection state change frequency parameter of the target virtual machine, and the first penalty coefficient is attenuated by using a first attenuation period to reflect the change of the connection state change frequency of the target virtual machine with time. The first penalty coefficient may be changed by adding one to each time the target virtual machine performs an online action or a offline action on the target virtual tunnel endpoint, or may be accumulated by other manners, for example, may be accumulated by other values, or the value accumulated each time is increased with the increase of the number of times, or other accumulation calculation manners are adopted. And as the connection state of the target virtual machine tends to be stable, i.e. after the first attenuation period is spaced, the target virtual machine does not have an online action or a offline action, the first penalty coefficient corresponding to the target virtual machine can be reduced by one, or the first penalty coefficient is reduced by other values, or the reduced value is increased or reduced along with the extension of time, or other accumulated calculation modes are adopted.
Based on this, in the information release control method of a virtual tunnel endpoint provided in the embodiment of the present application, the state change frequent criterion may specifically be: the first punishment coefficient corresponding to the target virtual machine is larger than the first preset times. When the ratio of the first punishment coefficient to the times is 1:1, the first punishment coefficient is adopted to be compared with the first preset times. If other accumulating modes are adopted, other types of thresholds can be correspondingly set. When the first punishment coefficient corresponding to the target virtual machine is larger than the first preset times, the condition that the state of the target virtual machine connected with the target virtual tunnel endpoint is changed frequently is considered, and then the target virtual tunnel endpoint is forbidden to issue a state update message of the target virtual machine to the border gateway protocol neighbor node. And when the first penalty coefficient corresponding to the target virtual machine is smaller than or equal to the first preset times, allowing the target virtual tunnel endpoint to issue a state update message of the target virtual machine to the border gateway protocol neighbor node.
However, the adoption of the above-described state change frequent criteria may cause the target virtual machine to switch between frequent and infrequent state changes, which is also disadvantageous for stable control. Therefore, it is preferable that the status change frequent criteria specifically are: the first punishment coefficient corresponding to the target virtual machine is larger than the first preset times, or the first punishment coefficient corresponding to the target virtual machine does not fall below the second preset times after being larger than the first preset times last time. That is, when the first penalty coefficient corresponding to the target virtual machine is greater than the first preset times, the condition that the state of the target virtual machine connected with the target virtual tunnel endpoint is changed frequently is considered, and then the target virtual tunnel endpoint is forbidden to issue the state update message of the target virtual machine to the border gateway protocol neighbor node. When the first penalty coefficient corresponding to the target virtual machine is reduced from the condition that the first penalty coefficient is larger than the first preset times to the condition that the first penalty coefficient is smaller than the first preset times, the oscillation suppression of the target virtual machine is not released, and the first penalty coefficient corresponding to the target virtual machine is waited to continue to be reduced to the condition that the second penalty coefficient is smaller than the second preset times (the second preset times are smaller than the first preset times), the target virtual tunnel endpoint is allowed to issue a state update message of the target virtual machine to the border gateway protocol neighbor node.
Example III
When a target virtual machine frequently drifts (switches) between different virtual tunnel endpoints, there may be no frequent change in the connection state of the target virtual machine detected by a single target virtual tunnel endpoint, but from the perspective of the entire cluster, the target virtual machine has frequently drifted.
On the basis of the above embodiment, in order to implement drift suppression of frequent drift of the target virtual machine between different virtual tunnel endpoints, in the information release control method of a virtual tunnel endpoint provided in the embodiment of the present application, S102: determining the connection state change frequency parameter of the target virtual machine according to the historical state change data specifically may include:
when the target virtual machine performs the action of changing the connected virtual tunnel endpoint once, adding one to a second punishment coefficient corresponding to the target virtual machine;
if the target virtual machine does not change the connected virtual tunnel endpoint after the second attenuation period is spaced, subtracting one from a second punishment coefficient corresponding to the target virtual machine;
wherein the second penalty coefficient is an integer not less than zero.
In specific implementation, the first penalty coefficient is used as a connection state change frequency parameter of the target virtual machine, and the second attenuation period is utilized to attenuate the first penalty coefficient so as to reflect the change of the connection state change frequency of the target virtual machine with time. The first penalty coefficient may be changed by adding one to each time the target virtual machine has drift of the virtual tunnel endpoint, or may be accumulated by other manners, for example, may be accumulated by other values, or the value accumulated each time is increased with the increase of the number of times, or other accumulation calculation manners are adopted. And as the connection state of the target virtual machine tends to be stable, that is, when the target virtual machine does not drift after the first attenuation period is spaced, the second penalty coefficient corresponding to the target virtual machine can be subtracted by one, or the second penalty coefficient is subtracted by other values, or the subtracted values are increased or decreased along with the extension of time, or other accumulated calculation modes are adopted.
Based on this, in the information release control method of a virtual tunnel endpoint provided in the embodiment of the present application, the state change frequent criterion may specifically be: the second punishment coefficient corresponding to the target virtual machine is larger than the third preset times. When the ratio of the second punishment coefficient to the times is 1:1, the second punishment coefficient is adopted to be compared with a third preset time. If other accumulating modes are adopted, other types of thresholds can be correspondingly set. When the second penalty coefficient corresponding to the target virtual machine is larger than the third preset times, the condition that the target virtual machine connected with the target virtual tunnel endpoint has frequent drift is considered, and the target virtual tunnel endpoint is forbidden to issue a state update message of the target virtual machine to the border gateway protocol neighbor node. And when the second penalty coefficient corresponding to the target virtual machine is smaller than or equal to the third preset times, allowing the target virtual tunnel endpoint to issue a state update message of the target virtual machine to the border gateway protocol neighbor node.
However, the adoption of the above-described state change frequent criteria may cause the target virtual machine to switch between frequent and infrequent state changes, which is also disadvantageous for stable control. Therefore, it is preferable that the status change frequent criteria specifically are: the second penalty coefficient corresponding to the target virtual machine is larger than the third preset times, or the second penalty coefficient corresponding to the target virtual machine does not fall below the fourth preset times after the second penalty coefficient corresponding to the target virtual machine is larger than the third preset times last time. That is, when the second penalty coefficient corresponding to the target virtual machine is greater than the third preset times, the condition that the target virtual machine connected with the target virtual tunnel endpoint has frequent drift is considered, and then the target virtual tunnel endpoint is forbidden to issue the state update message of the target virtual machine to the border gateway protocol neighbor node. When the second penalty coefficient corresponding to the target virtual machine is reduced from the condition that the second penalty coefficient is larger than the third preset times to the condition that the second penalty coefficient is smaller than the third preset times, the drift suppression of the target virtual machine is not released, and the second penalty coefficient corresponding to the target virtual machine is waited to continue to be reduced to the condition that the second penalty coefficient is smaller than the fourth preset times (the fourth preset times are smaller than the third preset times), the state update message of the target virtual machine is allowed to be issued to the border gateway protocol neighbor node by the target virtual tunnel endpoint.
Various embodiments of a virtual tunnel endpoint information release control method are detailed above, and on the basis of the embodiments, the application also discloses an information release control device, equipment and a computer readable storage medium of the virtual tunnel endpoint corresponding to the method.
