Detailed Description
The embodiment of the application provides a message transmission method, an information processing method and related equipment thereof, which are used for avoiding the problem of network scale caused by excessive tunnels under the condition of transmitting messages among gateway equipment clusters.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The following terms refer to the main network elements involved in the present application:
a gateway device: namely a VxLAN Gateway (VxLAN GW) (hereinafter collectively referred to as GW) for connecting VPCs of different regions.
The tenant device: the device on the tenant side may be a VPC or a Virtual Machine (VM) in the VPC, or may also be other devices, for example, a switch connected to the VM, where the switch may be a virtual switch, and a specific device is not limited herein.
The gateway equipment cluster: a cluster consisting of a set of gateway devices performing the same function (responsible for forwarding of the same set of VPCs).
An address server: the method is used for diffusing the mapping relation between the gateway equipment cluster and the gateway IP address combination, and the domain name identification of the gateway equipment cluster and the IP address combination corresponding to the domain name identification are stored, wherein the IP address combination comprises the IP addresses of at least two gateway equipment.
Target IP address combination: the IP addresses of at least two gateway devices in the target gateway device cluster are included, and in general, the IP addresses of all gateway devices in the target gateway device cluster are included.
A VxLAN tunnel is a point-to-point tunnel between a pair of VTEP addresses (i.e., the IP addresses of the gateway devices in this application). A cloud data center network is generally divided into a plurality of regions (regions), and each region has a special gateway device to connect VPCs in different regions.
In order to establish a connection between two gateway device clusters, in the prior art, as shown in fig. 1, GW1, GW2, GW3 represents a first gateway device cluster, GW4, GW5, GW6 represents a second gateway device cluster, each GW in the first gateway device cluster and the second gateway device cluster may have a VTEP address, as shown in fig. 1, 9 (3 × 3) independent VxLAN tunnels are established between the first gateway device cluster and the second gateway device cluster (i.e., two gateway device clusters need to store 9 forwarding information tables and 9 tunnel index information tables), each of which works independently, in this case, the actual gateway device cluster has no practical meaning, because tunnels are established independently between GWs, and when there are multiple heavy GWs in a gateway device cluster, the number of tunnels increases, and the final number of tunnels approximates to M × N, where M is the number in the first gateway device cluster, n is the number of GWs in the second gateway device cluster, which results in very complex network management and ultimately affects the scale of the entire network.
In order to solve the above problem, please refer to fig. 2, fig. 2 is a schematic view of an application scenario of a packet transmission method in this embodiment of the present application, in the schematic view, a first gateway device cluster and a second gateway device cluster are connected through a VxLAN tunnel, a gateway in the first gateway device cluster is responsible for packet forwarding of tenants VPC1, VPC2, and VPC3, and a gateway in the second gateway device cluster is responsible for packet forwarding of tenants VPC4, VPC5, and VPC6, where IP addresses of gateways in the first gateway device cluster and the second gateway device cluster belong to an underlay address space, and an IP address of a VPC belongs to an overlay, where a RegionA-vtep-GW in fig. 2 is a domain name identifier of the first gateway device cluster, and a RegionB-vtep-GW is a domain name identifier of the second gateway device cluster. The tenants VPC 1-VPC 6, the first gateway device cluster and the second gateway device cluster can all obtain the IP address combination of the next-hop gateway device cluster from the address server.
When the gateway device or the tenant device forwards the message, one IP address is selected from the IP address combination of the next-hop gateway device cluster as the IP address of the target gateway device to be sent as the destination. For example, when a tenant device (VPC1) sends a message to a gateway in a first gateway device cluster, first, an IP address combination in the first gateway device cluster is obtained, then, an IP address of a target gateway device is selected from the IP address combination in the first gateway device cluster and encapsulated in the message to be sent, when an IP address of the target gateway device is an IP address of GW1, GW1 receives the message, when the GW1 receives the message, a next hop, that is, an IP address combination in a second gateway device cluster is obtained, then, a target IP is determined from the IP address combination in the second gateway device cluster and encapsulated in the message as the target IP address to be sent, wherein the GW in the second gateway device cluster only receives the message that a destination IP address is the own GW IP address, so that only one tunnel needs to be established between the two gateway device clusters, and tunnel increase caused by too many gateways is avoided, the problem of influencing the network scale.
It should be noted that the message transmission method in the present application is mainly applied to a multi-source and multi-destination (multi-source and multi-destination) situation.
It should be noted that the message transmission method in the embodiment of the present application is not only applicable to the VxLAN gateway device cluster, but also applicable to other three-layer tunnel technologies, and a specific scenario is not limited here.

In this embodiment, the network device receives a first message, where the first message includes target tenant information, such as an IP address of VPC4 in fig. 2, where the network device may be a gateway device or a tenant device.
It should be noted that, before operating the message transmission method in the present application, the network device may first configure tunnel objects, where each tunnel object includes, but is not limited to:
the registering of the IP address to the address server by the gateway device specifically includes: and after receiving the IP address and the domain name identifier of the gateway device, the address server acquires an IP address combination corresponding to the domain name identifier according to the domain name identifier, and then stores the IP address of the gateway device in the IP combination.
It should be noted that all or a part of the gateways in the second gateway device cluster may also register an IP address with the address server.
It should be noted that the address server may be a Domain Name System (DNS) server, or may be another server, such as a service registration management server, and the specific type of the address server is not limited herein.
It should be noted that, when the gateway in the gateway device cluster changes (e.g., increases or decreases), the address server is notified in real time to change the IP address combination corresponding to the domain name of the gateway device cluster.
The purpose of registering the gateway IP addresses in the first gateway device cluster with the address server is to diffuse the domain name identifier of the first gateway device cluster and the IP addresses of the gateways in the cluster in the whole cloud network, so that other devices in the cloud network can obtain the domain name identifier and the IP addresses of all gateway devices under the domain name identifier. For example, when the tenant device needs to send a packet to the first gateway device cluster, an IP address combination of a gateway in the first gateway device cluster is obtained from the address server, and then an IP address is determined as a next hop address of the packet from the obtained IP address combination.
After the gateway IP in the gateway device cluster is registered with the address server, the address server stores the domain name identifier of the corresponding gateway device cluster and the IP address combination (list) corresponding to the domain name identifier, as shown in table 1:
TABLE 1
The network device also obtains a domain name identifier (RegionB-vtep-GW) of the opposite end according to the tunnel object, and then obtains an IP address combination (target IP address combination) of the opposite end from an address server (such as DNS) according to the domain name identifier:
DNS:getRequest(RegionB-vtep-GW)
the obtained information is as follows:
the step of acquiring, by the network device, the target IP address combination from the address server may specifically be:
the network device sends a request message containing a domain name identifier (such as a RegionB-vtep-GW) to an address server, and after receiving the request message, the address server searches an IP address combination corresponding to the target domain name identifier according to the target domain name identifier in the request message, and then determines the IP address combination as a target IP address combination and sends the target IP address combination to the network device.
After acquiring the target IP address combination, the network device creates a tunnel information table according to the target IP address combination and its own IP address (source IP address), that is, writes the target IP address combination and its own IP address into a corresponding location in the tunnel information table (the target IP address combination is written into a location corresponding to destination, and its own IP address is written into a location corresponding to source), where the tunnel information table further includes tunnel index information, and when the network device is a gateway device in a first gateway device cluster, the information in the tunnel information table is as follows:
when the network device is a tenant device (e.g., VPC1), the information in the tunnel information table is as follows:
wherein, creating the tunnel information table specifically may be:
the network equipment acquires the domain name identification of the target gateway equipment cluster according to the information in the tunnel object; and then, acquiring the target IP address combination from the address server according to the domain name identifier, and finally, creating the tunnel information table according to the target IP address combination and the IP address of the network equipment.
After the tunnel information table is created, the tunnel information table is issued to a data forwarding engine in the network device.
It should be noted that the domain name identifier of the target gateway device cluster may be configured in advance on the network device by an administrator through a command, or may be configured by the network device receiving a message sent by another control management device according to a message instruction; or the network equipment automatically generates and completes the configuration by running algorithm software; or may be a default value set upon software implementation of the network device; the specific manner of obtaining the domain name identifier of the target gateway device cluster is not limited herein.
402. And the network equipment obtains the tunnel index information corresponding to the target tenant information according to the target tenant information.
After receiving the first packet, a source gateway in the network device maps tenant information (for example, Vxlan Network Identifier (VNI) of Vxlan) in the first packet to a Virtual Private Network (VPN) Routing Forwarding table (Virtual Routing Forwarding, VRF), and searches a Forwarding information table by using a target tenant IP address in the target tenant information to obtain tunnel index information corresponding to the first packet, where the Forwarding information table may be a private network Forwarding information table.
The private network forwarding information table is as follows:
the private network forwarding information table and the tunnel information table are both required to be issued to a data forwarding engine in the network device.
403. And the network equipment obtains a target IP address combination corresponding to the tunnel index information according to the tunnel index information.
After the network device obtains the private network forwarding information table corresponding to the first packet, the network device searches the tunnel information table according to tunnel index information (out-tunnel-index) in the private network forwarding information table to obtain a target IP address combination, where in this application embodiment, the target IP address combination includes IP addresses of all gateways in the target gateway device cluster or includes IP addresses of some specified gateways in the target gateway device cluster, a gateway in the target gateway device cluster is a next hop of the first packet, the target gateway device cluster includes N gateways, and N is an integer greater than 1.
404. The network device determines the IP address of the target gateway device in the target IP address combination.
In this embodiment, after the network device obtains the target IP address combination, the IP address of the target gateway device is determined from the group of IPs, specifically, the IP address of the target gateway device may be determined in the group of IPs according to a load sharing algorithm, and the target gateway IP address combination may also be determined according to a polling method in the target IP address combination, so as to achieve an effect of balancing gateway loads in a cluster, where a specific method for determining the IP address of the target gateway device from the target IP address combination is not limited here.
405. The network equipment encapsulates the IP address of the target gateway equipment into the first message to obtain a second message.
When the network device is a tenant device, the network device encapsulates the IP address of the target gateway device into the first packet, and obtaining the second packet includes: and the tenant equipment encapsulates the source tenant IP address and the target tenant IP address into the inner layer of the first message, encapsulates the source tenant IP address and the target gateway equipment IP address into the outer layer of the first message, and obtains the second message, wherein the source tenant IP address is the IP address of the tenant equipment.

406. And the network equipment sends the second message to the target gateway equipment.
In this embodiment, the network device sends the second message through the underlay network, and since the IP address of the target gateway device is encapsulated in the second message, the target gateway corresponding to the IP address of the target gateway device in the target gateway device cluster receives the second message.
And after receiving the second message, the target gateway sends the message to the next hop equipment.
