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 application, 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 application.
At present, a router corresponding to a tenant network in a cluster and a transit switch in the cluster are in a one-to-one correspondence relationship, so that one transit switch needs to be added every time a tenant network is added in the cluster, and resource waste exists. And overlapping network segments in different clusters cannot communicate due to IP collisions.
Therefore, the cluster communication scheme is provided, interconnection cost among clusters can be reduced, and meanwhile the problem of IP conflict of overlapped network segments is solved.
Referring to fig. 1, an embodiment of the present application discloses a trunking communication method, including
S101, if any two clusters have an overlapped network segment, closing a dynamic interconnection function aiming at the overlapped network segment, and configuring static routes on a first virtual router and a second virtual router in the two clusters so as to realize communication connection of the overlapped network segment; and starting a dynamic interconnection function aiming at the non-overlapping network segments in the two clusters so as to enable the two clusters to synchronize the non-overlapping network segments to an interconnection database respectively, and realizing communication connection of the non-overlapping network segments through the interconnection database.
The closing or opening of the dynamic interconnection function may be accomplished by operating the cluster database of the cluster, specifically, operating the NB _ Global table of the northbound database of the cluster OVN. If the dynamic interconnection function is started, the OVN ic process of the local cluster fills the opened network segment route into an interconnection database, and other clusters can learn the contents to the local. Specifically, the command for closing the dynamic interconnection function of a certain network segment may be: ovn-nbctl set NB _ global. options: ic-route-blacklist [ < subnet segment >.
The process of configuring the static route may be: and adding ecmp high available static routes to a first virtual router and a second virtual router in the opposite-end cluster, so that the first virtual router leads the traffic to the second virtual router according to the configured static routes, and the second virtual router leads the traffic to the opposite-end cluster according to the configured static routes. Correspondingly, a static route is added to the second virtual router of the cluster, so that the second virtual router guides the flow to the first virtual router of the cluster according to the added static route.
S102, if no overlapped network segment exists in any two clusters, starting a dynamic interconnection function aiming at each network segment in the two clusters so as to enable the two clusters to synchronize self network segments to an interconnection database respectively, and realizing communication connection of each network segment in the two clusters through the interconnection database.
Referring to fig. 2, in each cluster, any tenant network is connected to a first virtual router, each first virtual router is connected to a virtual switch in the same cluster, the virtual switch in the cluster is connected to at least two second virtual routers, any second virtual router is connected to at least one virtual gateway, and each virtual gateway is connected to a virtual switch between the same clusters. The inter-cluster virtual switches in each cluster are created based on the interconnection database and are in the same network segment, so that each cluster can communicate through the inter-cluster virtual switches.
Wherein, a tenant network refers to: a network under a first virtual router. Within each cluster, any one tenant network corresponds to only one first virtual router.
It should be noted that step S101 and step S102 do not limit the execution order, that is: the two steps may be performed out of order.
In a specific embodiment, when any two clusters communicate, a Routing path is selected based on an ECMP (Equal-Cost multi path Routing) protocol to implement: and meanwhile, a plurality of routing links are used, so that the transmission bandwidth is increased, and the data transmission of the failed link can be backed up without time delay and packet loss. For example: when a request is sent to B in the cluster A, the traffic in the cluster A selects a static route at the first virtual router through the ECMP to reach the second virtual router of the next hop of the static route, and then the ECMP selects a static route at the second virtual router again to lead the traffic to the opposite-end cluster. In the B cluster, the traffic passes through the first virtual router and the second virtual router to reach a container or a virtual machine to be accessed.
In one embodiment, the creating process of the inter-cluster virtual switch in any cluster includes: any cluster respectively creates an inter-cluster virtual switch based on the switch name, the network segment and the interconnection database specified by the user. It can be seen that creating an inter-cluster virtual switch requires specifying the switch name, network segment, and north-south ports of the interconnected databases, so that each cluster can create switches with the same name and configure ports of the same network segment accordingly. Wherein, the north-south port of the interconnection database is appointed, so that each cluster can be conveniently connected with the interconnection database.
The interconnection database is an OVN (open Virtual network) database. OVN is the control plane of OVS (open vSwitch), which adds the native support to the virtual network for OVS, and greatly improves the performance and scale of OVS in the practical application environment. The OVS is a high quality multi-layer virtual switch.
In a specific embodiment, if a newly-built tenant network exists in any cluster, the dynamic interconnection function of the network segment corresponding to the currently-built tenant network is closed, a corresponding first virtual router is created for the currently-built tenant network based on a cluster database of the current cluster, and the first virtual router is connected to an intra-cluster virtual switch in the current cluster. It can be seen that, before the newly-built tenant network is connected with the virtual switch in the cluster, the dynamic interconnection function of the automatic notification is closed, and subsequently, if the network segment corresponding to the newly-built tenant network is confirmed not to be overlapped with other clusters, the dynamic interconnection function can be started. And if the network segment corresponding to the newly-built tenant network is confirmed to be overlapped with other clusters, performing static routing configuration.
In a specific embodiment, if any tenant network in any cluster is deleted, the first virtual router corresponding to the tenant network is deleted.
As can be seen, in this embodiment, for an overlapping network segment existing in two clusters, static routes may be configured on a first virtual router and a second virtual router in the two clusters to implement communication connection of the overlapping network segment; for non-overlapping network segments, cluster communication can be realized based on a dynamic interconnection function and an interconnection database, so that the problem of IP conflict of overlapping network segments is solved. Meanwhile, only one inter-cluster virtual switch needs to be arranged in the cluster, and the router corresponding to each tenant network in the same cluster is connected with the inter-cluster virtual switch, so that the interconnection cost among the clusters is reduced.
The following examples are presented by way of example of two clusters, openstack and kubernets. The interconnection of the openstack cluster and the kubernets cluster introduced below is still based on OVN, and three layers of high availability intercommunication can be realized. The scheme does not depend on a third party component, and three-layer intercommunication of openstack and kubernets can be quickly realized only by using OVN native functions such as OVN ic, static routing, a virtual machine router, a virtual switch and the like. The switch, the router, the gateway and the like related to the embodiment are all virtual devices.
Referring to fig. 3, the intra-cluster transit switches and inter-cluster interconnection routers in the openstack and kubernets can connect the vpc virtual router in the cluster to the outside, and the inter-cluster transit switches shared by the openstack and the kubernets can interconnect the openstack and the kubernets. Fig. 3 illustrates an inter-cluster transit switch that is logically two and thus shared by openstack and kubernets.
Specifically, the interconnection system shown in fig. 3 can be implemented according to the following steps:
1. and (4) starting an OVN ic database (namely an interconnection database), and respectively starting an OVN ic function in openstack and kubernets.
2. And respectively creating a required transfer switch in the cluster and an interconnection router between the clusters in the two clusters, wherein one vpc virtual router in the cluster is an outlet of one tenant network in the cluster.
3. The intra-cluster transit switch is connected with the vpc virtual router through an ovn-nbctl command, the intra-cluster transit switch is connected with the inter-cluster interconnection router, and the inter-cluster transit switch is connected with 2 inter-cluster interconnection routers. The port of the gateway node is the port of the inter-cluster interconnection router, so that the inter-cluster transit switch and the inter-cluster interconnection router are directly connected, but logically, traffic passes through the gateway node.
The transit switches in the two clusters mainly make the flow circulate in the cluster, so the network segment and the ip address can be the same. Virtual ip of interconnection routers and gateway ports among clusters needs to be inherited to network segments of transit switches among clusters, so ip addresses cannot be overlapped.
Further, aiming at the non-overlapped subnets of the two clusters, the subnets are configured to automatically announce to realize three-layer intercommunication, ovn ic learns the gateway information of the opposite end and writes the gateway information into the openstack/kubernets cluster, and the high availability of the network access gateway is fully automatically realized. For overlapping subnets of two clusters: and (3) closing the automatic notification of the subnet, adding an ecmp static route of a certain ip in the vpc virtual router, and enabling the next hop to be an inter-cluster interconnection router, thereby realizing high availability of the gateway of the outgoing network. And an ecmp static route of the ip is configured on the interconnection router among the clusters, and the next hop is an opposite-end cluster gateway port virtual ip, so that the high availability of the network access gateway is realized. Referring to fig. 4, the IP of each device may be configured as in fig. 4 to implement communication.
The static route added by the vpc router leads the flow to the inter-cluster transit switch, and the inter-cluster transit switch is used for communicating the three-layer flow of openstack and kubernets. A plurality of ecmp routing gateways deployed in an Openstack/kubernets cluster can realize high availability of communication in the cluster and among the clusters, and improve three-layer intercommunication availability. And identifying an overlapped network segment among clusters, closing the ovn ic dynamic announcement of the overlapped network segment, and adding a 32-bit network segment static route to the vpc virtual router and the interconnection router to realize three-layer intercommunication of openstack and kubernets overlapped network segment traffic. And the ovn ic native network segment dynamic notification function can rapidly get through the traffic of the non-overlapping network segment only by adding a static route to the vpc virtual router.
It can be seen that, in this embodiment, after the cluster separately creates the inter-cluster interconnection router, when each vpc router is added, only the relationship between the vpc virtual router and the transit switch in the cluster needs to be configured, so that three-layer intercommunication between clusters can be quickly achieved, and cumbersome configuration can be reduced. As shown in fig. 3, each cluster contains 2 inter-cluster interconnection routers, and a plurality of gateway nodes. After the outgoing cluster traffic is statically routed through the ecmp gateway of the vpc virtual router, the traffic reaches different outgoing gateways, and the outgoing gateway can be highly available. The relay switch between the clusters associates the openstack gateway with the kubernets gateway, and the flow reaches different network access gateways after the cluster access flow is statically routed through the ecmp gateway of the inter-cluster interconnection router, so that the high availability of the network access gateways is realized.
Thus, the present application has the following advantages:
1. using OVN technology for both clusters avoids the added operational complexity and development cost of using multiple technology stacks.
2. Three-layer intercommunication of openstack and kubernets high availability can be rapidly realized by using ovn native functions.
3. The method can support the intercommunication of the vpc routers of a plurality of tenants, and can quickly finish the change of the relationship between the vpc router and the transit switch in the cluster when the vpc router of one tenant is added or deleted. The inter-cluster network isolation and high availability of access gateways are realized through simple configuration in a loose coupling mode.
4. The gateway ecmp is available, and the availability of three-layer intercommunication is greatly improved.
