However, in some actual business scenarios, the cloud platform service and the tenant network instance are required to perform message transmission, for example, the cloud platform service needs to send various operation instructions to the tenant network instance to manage the tenant network instance, and for example, the tenant network instance needs to feed back an execution result of the operation instructions to the cloud platform service or report a service state of the tenant network instance.
The existing message transmission generally comprises the following two methods: one method is that the tenant network and the management network use two network cards, namely, two networks are provided for the tenant network instance, the tenant access message is transmitted through the tenant network, and the management access message is transmitted through the management network without mutual interference; another method is to transmit the message received on the tenant network to the management network through the proxy, and transmit the message received on the management network to the tenant network through the proxy.

In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It is noted that the terms "comprises" and "comprising," and any variations thereof, in the description and claims of the present invention and in the foregoing figures, 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 or inherent to such process, method, article, or apparatus.
Example 1
Fig. 1 is a flowchart of a message transmission method provided in an embodiment of the present invention, where the embodiment is applicable to a case of performing message transmission on a message to be transmitted safely and reliably, and the method may be performed by a message transmission device, where the device may be implemented by software and/or hardware, and may generally be directly integrated in an electronic device that performs the method, where the electronic device may be a terminal device or a server device, and the embodiment of the present invention does not limit a type of electronic device that performs the message transmission method. Specifically, as shown in fig. 1, the message transmission method specifically includes the following steps:
S110, obtaining a message to be transmitted, and determining a target tenant network instance corresponding to the message to be transmitted and message attribute information of the message to be transmitted.
The message to be transmitted may be a message waiting for transmission. It is understood that the message to be transmitted may be a message communicated between the cloud platform service and the tenant network instance. The cloud platform service may be a service provided by a control node in the cloud computing platform, for example, may be a cloud database service, a cloud middleware service, a big data cluster service, or a cloud container service provided by the control node, which is not limited in the embodiment of the present invention. The tenant network instance may be an instance in each computing node in the cloud computing platform, for example, may be a physical machine, a virtual machine, or a container in the computing node, which is not limited by the embodiment of the present invention. That is, the cloud platform service may be a service in a management network and the tenant network instance may be an instance in the tenant network. It will be appreciated that the tenant network (Virtual Private Cloud, VPC), i.e. the tenant virtual private cloud, may be a custom logically isolated network space in a cloud computing platform, which is fully controlled by users, supporting custom network segment partitioning and routing policies, etc., similar to the networks partitioned by conventional data centers.
The target tenant network instance may be one target instance of each tenant network instance that needs to perform message transmission. The message attribute information may be any attribute information of the message to be transmitted, for example, may be message transmission direction information, which is not limited in the embodiment of the present invention.
In the embodiment of the invention, the message to be transmitted is acquired to determine the target tenant network instance corresponding to the message to be transmitted, and the message attribute information of the message to be transmitted is determined.
S120, determining a communication network address corresponding to the target tenant network instance according to the message attribute information; wherein the communication network address is a platform built-in network address, a platform external network address or an example network address.
The communication network address may be a network address capable of performing any communication corresponding to the network instance of the target tenant, for example, may be a network address communicating with an internal resource of the tenant network, may be a network address communicating with an external resource of the cloud platform, may be a network address communicating with a service of the cloud platform, or the like, which is not limited in the embodiment of the present invention.
The platform built-in network address may be a network address of a cloud computing platform built-in network. The cloud computing platform built-in network may be a network between the cloud platform service and each tenant network instance. That is, the platform built-in network address may be a network address of communication between the cloud platform service and the tenant network instance. Optionally, the cloud computing platform built-in network may be an IP of a management elastic public network, and may be a network planned for direct communication between each tenant network instance and the cloud platform service.
Wherein the platform external network address may be a network address of a cloud computing platform external network. The cloud computing platform external network may be a network between cloud platform external resources and each tenant network instance. That is, the cloud platform external network address may be a network address of communication between the cloud platform external resource and the tenant network instance.
Wherein the instance network address may be a network address of a network within a tenant network instance in the cloud computing platform. The tenant network instance internal network may be a network address of each tenant network instance internal communication, a network that can be directly accessed by cloud resources within the VPC. That is, the instance network address may be a network address that is communicated internally to each tenant network instance, a network address that can be directly accessed by cloud resources within the VPC. It can be appreciated that the tenant network instance internal network cannot be accessed by resources outside the cloud platform, and if it needs to be accessed by resources outside the cloud platform, it needs to bind the platform external network address.
In the embodiment of the invention, after the target tenant network instance corresponding to the message to be transmitted and the message attribute information of the message to be transmitted are determined, the communication network address corresponding to the target tenant network instance can be further determined according to the message attribute information. Specifically, the communication network address corresponding to the target tenant network instance may be a built-in network address of a platform corresponding to the target tenant network instance, or may be an external network address of a platform corresponding to the target tenant network instance, or may also be an instance network address corresponding to the target tenant network instance. It is understood that different message attribute information may correspond to different communication network addresses.
Optionally, the platform built-in network address, the instance network address, and the platform external network address are network addresses of non-identical communication network segments. That is, any two networks among the built-in network of the cloud computing platform, the external network of the cloud computing platform and the internal network of the tenant network instance are physically isolated, so as to ensure the security of the network of the cloud platform.
According to the technical scheme, the specific implementation mode of each network address included in the communication network address is limited, and the communication network segment of each network address is limited, so that the security of the cloud platform network is further guaranteed.
S130, according to the communication network address and the message attribute information, the message to be transmitted is transmitted.
In the embodiment of the invention, after the communication network address corresponding to the target tenant network instance is determined according to the message attribute information, the message to be transmitted can be further transmitted according to the communication network address and the message attribute information, so that the message transmission between the cloud platform service and the tenant network instance is realized.
According to the technical scheme, the message to be transmitted is transmitted according to the communication network address and the message attribute information, so that the problems of network resource waste, relatively complex operation and maintenance, relatively high cloud service loss, relatively high cloud service cost and the like in the prior art are solved, the message to be transmitted can be transmitted safely and reliably, the utilization rate of network resources is improved, the operation and maintenance complexity is reduced, and the performance loss and the cloud service cost of cloud service are reduced.
Example two
Fig. 2 is a flowchart of a message transmission method provided by a second embodiment of the present invention, where the foregoing technical solutions are further refined, and various specific alternative implementation manners of determining, according to the message attribute information, a communication network address corresponding to the target tenant network instance, and transmitting, according to the communication network address and the message attribute information, the message to be transmitted are provided. The technical solution in this embodiment may be combined with each of the alternatives in one or more embodiments described above. As shown in fig. 2, the method may include the steps of:
s210, obtaining a message to be transmitted, and determining a target tenant network instance corresponding to the message to be transmitted and message attribute information of the message to be transmitted.
Optionally, the message attribute information may include incoming traffic information; the message to be transmitted of the incoming traffic information may be a message sent to each tenant network instance by the cloud platform service. The message attribute information can also comprise forward flow information; the message to be transmitted, which goes to the traffic information, may be a message sent to the cloud platform service by each tenant network instance.
The incoming traffic information may be message attribute information with a transmission direction being an incoming direction. The outgoing traffic information may be message attribute information with the transmission direction being outgoing. It can be understood that if the message attribute information of the message to be transmitted is the incoming flow information, it is indicated that the message to be transmitted is a message sent to each tenant network instance by the cloud platform service. If the message attribute information of the message to be transmitted is the forward flow information, the message to be transmitted is a message sent to the cloud platform service by each tenant network instance.
Specifically, after the message to be transmitted is acquired, whether the message attribute information of the message to be transmitted is the incoming flow information or the outgoing flow information can be further determined, so as to determine the communication network address corresponding to the network instance of the target tenant according to the message attribute information.
Alternatively, the message attribute information of the message to be transmitted may be determined according to the IP address and the port information of the message to be transmitted. For example, if the destination address of the message to be transmitted is an IP address corresponding to the cloud platform service, or the source address of the message to be transmitted is an IP address corresponding to the tenant network instance, or the port information in the message to be transmitted is a port accessing the cloud platform service, which indicates that the message to be transmitted is a message sent to the cloud platform service by the tenant network instance, it may be determined that the message attribute information of the message to be transmitted is the outgoing flow information.
In another example, if the destination address of the message to be transmitted is an IP address corresponding to the tenant network instance, or the source address of the message to be transmitted is an IP address corresponding to the cloud platform service, or the port information in the message to be transmitted is a port in the access tenant network instance, which indicates that the message to be transmitted is a message sent to the tenant network instance by the cloud platform service, it may be determined that the message attribute information of the message to be transmitted is ingress traffic information.
S220, determining the communication network address corresponding to the target tenant network instance according to the message attribute information.
Optionally, determining the communication network address corresponding to the network instance of the target tenant according to the message attribute information may include: and under the condition that the message attribute information is determined to be the incoming flow information, determining an instance network address corresponding to the network instance of the target tenant, and determining the instance network address as the communication network address.
Optionally, determining the communication network address corresponding to the network instance of the target tenant according to the message attribute information may include: and under the condition that the message attribute information is the destination flow information, determining the destination address of the message to be transmitted, and determining the communication network address according to the destination address of the message to be transmitted.
Specifically, after determining the target tenant network instance corresponding to the message to be transmitted and the message attribute information of the message to be transmitted, whether the message attribute information is the incoming traffic information or the outgoing traffic information can be further determined, so that when the message attribute information is the incoming traffic information, the instance network address corresponding to the target tenant network instance is determined, and the instance network address is determined to be the communication network address. And when the message attribute information is the forward flow information, determining the destination address of the message to be transmitted, thereby determining the communication network address according to the destination address of the message to be transmitted. It can be understood that the destination address of the message to be transmitted may be the address for receiving the message, and may be determined according to the field content corresponding to the destination address in the message to be transmitted.
Optionally, determining the communication network address according to the destination address of the message to be transmitted may include: under the condition that the destination address of the message to be transmitted meets the preset platform built-in network condition, determining the platform built-in network address corresponding to the network instance of the target tenant, and determining the platform built-in network address as the communication network address; and under the condition that the destination address of the message to be transmitted does not meet the preset platform built-in network condition, determining the platform external network address corresponding to the target tenant network instance, and determining the platform external network address as the communication network address.
The preset platform built-in network condition may be a preset platform built-in network condition that a destination address of a message to be transmitted needs to meet, for example, the destination address of the message to be transmitted may be within a communication network segment range corresponding to the cloud computing platform built-in network, which is not limited in the embodiment of the present invention.
Specifically, when the message attribute information is the forward flow information, after determining the destination address of the message to be transmitted, it may be further determined whether the destination address of the message to be transmitted meets the preset platform built-in network condition. When the destination address of the message to be transmitted meets the preset platform built-in network condition, the platform built-in network address corresponding to the network instance of the target tenant can be determined, so that the platform built-in network address is determined to be the communication network address. When the destination address of the message to be transmitted does not meet the preset built-in network condition of the platform, the external network address of the platform corresponding to the network instance of the target tenant can be determined, so that the external network address of the platform is determined as the communication network address.
According to the technical scheme, a specific implementation mode for determining the communication network address according to the destination address of the message to be transmitted is provided, and the control message and the data message can be separated, so that the safety of message transmission is further improved.
Optionally, before determining the communication network address corresponding to the target tenant network instance according to the message attribute information, a cloud computing platform built-in network, a cloud computing platform external network and a tenant network instance internal network may be created, and different communication network segments are respectively allocated to the cloud computing platform built-in network, the cloud computing platform external network and the tenant network instance internal network, so as to further allocate network addresses belonging to each communication network segment, that is, a platform built-in network address, a platform external network address and an instance network address, to each tenant network instance.
S230, determining the address to be converted of the message to be transmitted according to the message attribute information.
The address to be translated may be an address to be translated. It may be understood that the address corresponding to the message to be transmitted may include a source address and a destination address, and then any one of the source address and the destination address may be determined as the address to be converted.
In the embodiment of the invention, after the target tenant network instance corresponding to the message to be transmitted and the message attribute information of the message to be transmitted are determined, the address to be converted of the message to be transmitted can be further determined according to the message attribute information.
It should be noted that fig. 2 is only a schematic diagram of one implementation manner, and the step S220 and the step S230 do not have a sequential relationship, and the step S220 may be implemented first, then the step S230 may be implemented first, then the step S220 may be implemented, or both may be implemented in parallel or alternatively implemented.
Optionally, determining the address to be converted of the message to be transmitted according to the message attribute information may include: and under the condition that the message attribute information is determined to be the incoming flow information, determining the destination address of the message to be transmitted as the address to be converted.
Optionally, determining the address to be converted of the message to be transmitted according to the message attribute information may include: and under the condition that the message attribute information is the destination flow information, determining the source address of the message to be transmitted as the address to be converted.
Specifically, after determining the target tenant network instance corresponding to the message to be transmitted and the message attribute information of the message to be transmitted, it may be further determined whether the message attribute information is incoming traffic information or outgoing traffic information. When the message attribute information is the incoming flow information, the destination address of the message to be transmitted can be determined as the address to be converted. When the message attribute information is the forward flow information, the source address of the message to be transmitted can be determined as the address to be converted.
According to the technical scheme, the specific application scenario that the message attribute information comprises the incoming flow information is provided, so that when the message attribute information is the incoming flow information, the corresponding communication network address and the address to be converted are determined, the accuracy of message transmission can be improved, and the reliability of message transmission is further improved. The specific application scenario that the message attribute information comprises the forward flow information is also provided, so that when the message attribute information is the forward flow information, the corresponding communication network address and the address to be converted are determined, the accuracy of message transmission can be improved, and the reliability of message transmission is further improved.
S240, address conversion is carried out on the communication network address and the address to be converted, and message transmission is carried out on the message to be transmitted according to an address conversion result.
The address conversion result may be a result obtained after address conversion is performed.
In the embodiment of the invention, after determining the communication network address corresponding to the network instance of the target tenant according to the message attribute information and determining the address to be converted of the message to be transmitted according to the message attribute information, the communication network address and the address to be converted can be further subjected to address conversion so as to transmit the message to be transmitted according to the address conversion result.

When the message attribute information is the forward flow information, the address to be converted is the source address of the message to be transmitted, and when the communication network address is the built-in network address of the platform corresponding to the network instance of the target tenant, the address conversion is carried out on the source address of the message to be transmitted and the built-in network address of the platform, and the address conversion result is that the source address of the message to be transmitted is changed into the built-in network address of the platform; when the communication network address is a platform external network address corresponding to the target tenant network instance, performing address conversion on the source address of the message to be transmitted and the platform external network address, wherein the address conversion result is that the source address of the message to be transmitted is changed into the platform external network address; and then the message transmission of the message to be transmitted is carried out according to the changed address.

Optionally, the method may further include: determining a port access rule corresponding to a network instance of a target tenant, and determining a target access port corresponding to a message to be transmitted; and filtering the message to be transmitted according to the target access port and the port access rule.
The port access rule may be a rule that the tenant network instance accesses a port in the cloud platform service. It will be appreciated that multiple ports may be included in the cloud platform service, with the same or different ports being accessible to different tenant network instances. I.e. different tenant network instances may correspond to the same or different port access rules. The target access port may be a port to which the message to be transmitted wants to access. The message filtering may be to filter the message to be transmitted, so as to discard the message that does not meet the port access rule.
Specifically, the method may further include determining a port access rule corresponding to the network instance of the target tenant, and determining a target access port corresponding to the message to be transmitted, so as to filter the message to be transmitted according to the target access port and the port access rule. Specifically, filtering the message to be transmitted according to the target access port and the port access rule may include: when the target access port meets the port access rule, allowing message transmission of the message to be transmitted; and when the target access port does not meet the port access rule, not allowing message transmission of the message to be transmitted, and discarding the message to be transmitted.

Example III
In order to enable those skilled in the art to better understand the message transmission method of the present embodiment, a specific example is described below.
Fig. 3 is an exemplary architecture diagram of a cloud computing platform according to a third embodiment of the present invention, where, as shown in fig. 3, the cloud computing platform may include a cloud platform service disposed at a control node, a lease network gateway disposed at a computing node, and a VPC instance (i.e., a tenant network instance). The cloud platform service can provide service operations of various cloud platform services for tenants through a management network, and perform control and management operations on the VPC instance through a built-in network (i.e., a built-in network of the cloud computing platform). The VPC instance may be a cloud service instance created by a tenant, may execute an operation instruction from the cloud platform service and feed back an execution result, and may also report a self service state to the cloud platform service at regular time. It will be appreciated that the operation messages of the VPC instance are all performed by the VPC network.
The lease network gateway can adopt a distributed design, one lease network gateway can be arranged in each computing node, and the lease network gateway can be a module realized based on an OpenFlow flow table. OpenFlow is a network communication protocol that can control the forwarding plane of a switch or router on a control network, thereby changing the network path taken by network packets. The network gateway can monitor network segment messages corresponding to the built-in network and the VPC network (namely, the internal network of the tenant network instance) through the lease pipe network gateway, and meanwhile, the access authority control is carried out on the messages through a security policy (such as an access control list ACL, which can be an access control technology based on the packet filtering realized by Openflow, and can filter the data packets on the ports according to the set conditions, allow the data packets to pass or be discarded), so that the message forwarding function between the tenant network and the built-in network is realized under the condition of safety and reliability. That is, the message transmission method according to the embodiment of the present invention may be implemented through a lease network gateway.
Fig. 4 is an example flowchart of a message transmission method provided in the third embodiment of the present invention, as shown in fig. 4, where the method specifically may include:
step 1, planning/creating a communication network in a cloud computing platform. Specifically, a built-in network (such as an MFIP network in fig. 4) is planned in the cloud computing platform, and a communication network segment of the built-in network is determined, for example, 100.126.0.0/16; creating an external network (such as the FIP network in fig. 4, i.e., the cloud computing platform external network), and determining a communication network segment of the external network, which may be 10.10.0.0/24, for example; a VPC network (e.g., the network corresponding to Fixed IP in fig. 4) is created and the communication network segment of the VPC network is determined, which may be 192.168.0.0/24, for example. It will be appreciated that the networks are physically isolated from each other, and from each other, from the management network.
And step 2, distributing network addresses for the VPC examples. Specifically, each VPC instance in the cloud computing platform is assigned a platform built-in network address (i.e., MFIP network address), a platform external network address (i.e., FIP network address), and an instance network address (i.e., fixed IP address). For example, VPC example 1 was assigned a platform internal network address of 100.126.0.3, a platform external network address of 10.10.0.3, and an example network address (i.e., fixed IP) of 192.168.0.3.
And 3, transmitting the message to be transmitted through the leased network gateway. Specifically, a message path of a message to be transmitted is determined through a lease network gateway, so that the message is transmitted according to the message path. It will be appreciated that the management network is only responsible for providing services of the cloud platform itself, such as message queues, mysql, intermediate keys in the compute nodes, i.e. the management network only accesses public services in the compute nodes, and cannot access VPC instances in the compute nodes through the management network.
The first case, i.e. the case where the message path is the outgoing traffic path (i.e. the message attribute information is the outgoing traffic information):
(1) The VPC instance sends a message (i.e. a message to be transmitted) through the VPC network, when the message arrives at the leased network gateway, the destination address of the message is determined, and if the destination address belongs to the built-in network segment (i.e. 100.126.0.0/16 network), the source address of the message is converted into the platform built-in network address corresponding to the VPC instance (e.g. 100.126.0.3 of VPC instance 1). If the destination address does not belong to the internal network segment, the source address of the message is translated to a network address external to the platform (as 10.10.0.3 of VPC instance 1).
(2) And (3) carrying out ACL rule filtering (namely message filtering) on the message, if the message meets the ACL rule, allowing the message to pass, and if the message does not meet the ACL rule, discarding the message.
(3) And the message after ACL inspection is sent to the network by the leased network gateway through the computing node network card, finally reaches the built-in network card of the control node, and is delivered to the cloud platform service program by the control node, and the cloud platform service program finishes processing and sends an operation result to a client through the management network.
The second case, that is, the case where the packet path is an incoming traffic path (that is, the packet attribute information is incoming traffic information):
(1) The client operates the VPC instance of the cloud platform management interface through the management network, and the cloud platform service sends specific operation (namely, message) to the lease network gateway through the built-in network.
(2) The message arrives at the lease network gateway and is filtered by ACL rules.
(3) The destination address of the message is converted to an intranet address (e.g., 192.168.0.3 of VPC instance 1).
(4) And forwarding the message to a virtual network bridge, wherein the virtual network bridge forwards the message to a VPC instance, and the VPC instance forwards the message to a cloud database resident program.
According to the technical scheme, two networks of one network card can be realized, namely, one intranet IP (namely, an example network address) is bound with two public network IPs (namely, a platform built-in network address and a platform external network address) at the same time, so that message transmission of a control message through the platform built-in network address is realized, and message transmission of a data message through the platform external network address is realized; and by adopting a distributed design, address conversion and message filtering are realized in the computing nodes, so that the flow path is shortened, the performance of the cloud computing platform is improved, and meanwhile, the robustness of the cloud computing platform is further improved.
