In some optional embodiments, after notifying the message characterizing the increased network orchestration cluster by a preset notification manner, the method further includes:

And responding to the network arrangement cluster increasing instruction, and determining the configuration information of the newly-added network arrangement cluster in the network arrangement cluster increasing instruction.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present application, it should be noted that, unless explicitly stated and limited otherwise, the term "connected" should be interpreted broadly, and for example, it may be directly connected, or it may be indirectly connected through an intermediate medium, or it may be communication between two devices. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.

In the cloud computing architecture, network resources of a cloud data center are uniformly managed through a network orchestration cluster (such as a Neutron component based on an OpenStack framework, where OpenStack is an open-source large-scale cloud computing architecture, and Neutron is a component responsible for providing virtual network services). Referring to fig. 1, in a single orchestration cluster architecture, service requests of all tenants are processed through one orchestration cluster.

Due to the limited processing power of a set of network orchestration clusters, MQ blocking between plug in and Agent of the network orchestration cluster is often caused. In addition, in order to ensure that the tenant service is issued and processed according to the needs and the processing time sequence, the tenant lock is adopted inside, the service cannot be processed in parallel, and the processing efficiency is low.

A single network orchestration cluster cannot support large-scale cloud network service deployment and cannot flexibly expand capacity. As the scale of cloud network service increases, the single network arrangement cluster is difficult to meet the requirements of the cloud network service, and a network arrangement cluster cascading scheme appears.

Referring to fig. 2, in some embodiments, domain network arrangement clusters corresponding to AZs are set, and all domain network arrangement clusters are managed by a central network arrangement cluster. That is, the network arrangement clusters are arranged through the network arrangement clusters, and a plurality of domain network arrangement clusters are connected in a cascading manner for unified management.

However, the domain network arrangement clusters are deployed by resource clusters, and the services of the same tenant may be divided into different domain network arrangement clusters, and because the data of the same tenant has relevance (such as distributing IP addresses in the tenant through multiple service requests), the central network arrangement cluster needs to perform not only the domain network arrangement cluster distribution, but also the arrangement data of all domain network arrangement clusters needs to be reserved, so that the processing performance of the resource arrangement system is affected. When the traffic scale is large, the processing performance of the central network orchestration cluster will be severely degraded. In addition, the domain network arrangement clusters are deployed according to the resource clusters, and when the traffic of the resource clusters is very small, a whole set of network arrangement clusters are required to be deployed, so that the resource waste of the network arrangement clusters is caused.

Referring to fig. 3, in some embodiments, network element arrangement, authentication, charging, and other functions are integrated in a cloud management platform, and are mainly used for managing a huge number of network function virtualization (abbreviated as NFV) network elements. The network element is controlled by a software defined network (English: software Defined Network, abbreviated: SDN) controller in the gateway control layer, and the network element is forwarded by the network element forwarding layer.

The above approach relies on high-performance databases, message queue middleware, etc., and is not applicable to the OpenStack framework.

In view of this, an embodiment of the present application provides a device allocation method, a device, and a resource scheduling system, so as to improve the processing performance and flexibility of the resource scheduling system.

Referring to fig. 4, the resource arrangement system provided in this embodiment includes a gateway cluster, a plurality of network arrangement clusters, and a plurality of resource clusters, where a plurality of service devices are disposed in any one of the resource clusters, and the same resource cluster belongs to the same AZ;

Illustratively, the gateway cluster may employ an open source gateway architecture, such as Zuul (an application programming interface gateway), nmginx (a high-performance hypertext transfer protocol and reverse proxy web server), and the like. In implementation, the gateway cluster includes a certain number of servers, and the number of member servers in the gateway cluster can be extended according to an actual application scenario, that is, the embodiment supports the lateral extension of the servers in the gateway cluster.

In this embodiment, since the gateway cluster only needs to maintain the correspondence (key-value type data) between the network orchestration cluster and the tenants, and does not need to maintain the orchestration data of all the network orchestration clusters, the processing logic of the gateway cluster is simplified, so that the gateway cluster can adopt dis (a lightweight buffer) to perform data caching; or a CACHE (a kind of CACHE) is selected as the storage scheme for fast access.

In this embodiment, the specific number of network arrangement clusters in the resource arrangement system is not limited, and fig. 4 illustrates M network arrangement clusters, in implementation, more or fewer network arrangement clusters may be set, and in a use process, the network arrangement clusters may be laterally expanded (i.e., the number of network arrangement clusters is increased).

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems with reference to the drawings and specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 5 is an interaction flow chart of a first device allocation method according to an embodiment of the present application, as shown in fig. 5, including the following steps:

Step S501: and the gateway cluster responds to the service request triggered by the target tenant, and determines the network arrangement cluster corresponding to the target tenant based on a preset corresponding relation.

The preset corresponding relation comprises a corresponding relation between a network arrangement cluster and a tenant, and the same tenant in the preset corresponding relation corresponds to the same network arrangement cluster.

According to the embodiment, the network arrangement clusters are not deployed according to the resource clusters, but one tenant is associated with a unique network arrangement cluster, after the gateway cluster receives the service request triggered by the target tenant, the network arrangement cluster corresponding to the target tenant is determined based on the preset corresponding relation, namely, the gateway cluster only needs to maintain the corresponding relation between the network arrangement clusters and the tenants, all the service requests of the same tenant are sent to the same network arrangement cluster, the data relevance among different network arrangement clusters is reduced, the gateway cluster does not need to maintain the arrangement data of all the network arrangement clusters, the processing logic of the gateway cluster is simplified, and the processing performance of the resource arrangement system is improved.

In implementation, all service requests of the same tenant need to be sent to the same network arrangement cluster, so that the same tenant in the preset corresponding relationship corresponds to the same network arrangement cluster, that is, the relationship between the tenant and the network arrangement cluster is one-to-one or many-to-one.

Step S502: and the gateway cluster sends the service request to the corresponding network arrangement cluster.

In this embodiment, the gateway cluster only needs to maintain the correspondence between the network orchestration cluster and the tenant, and the actual resource orchestration needs to be implemented by the network orchestration cluster, based on which the gateway cluster needs to send the service request to the corresponding network orchestration cluster.

Step S503: the network arrangement cluster determines a target resource cluster corresponding to the service request.

Determining the target resource cluster corresponding to the service request comprises the following steps:

If the service request carries the identification information of the target resource cluster, the target resource cluster is based on the identification information of the target resource cluster;

otherwise, determining the resource cluster of the virtual machine of the tenant as the target resource cluster.

For example, the tenant may directly specify the target resource cluster, for example, the identification information of the target resource cluster is placed in the service request, and then the target resource cluster may be determined directly based on the identification information of the target resource cluster; or the tenant does not specify the target resource cluster, and the resource cluster where the virtual machine (i.e. the service host of the tenant) allocated by the cloud computing platform is located is determined as the target resource cluster.

Step S504: and the network arrangement cluster allocates target business service equipment for the target tenant from a plurality of business service equipment of the target resource cluster based on the type of the business request.

In this embodiment, different types of service requests need to use different cloud network resources, and also correspond to different network service entities (i.e. the service devices mentioned above, which are used as computing nodes in the cloud data center).

Exemplary cloud Network resources include routers (english: router), computer networks (english: network), subnets (english: subnet), interfaces (english: port), security groups, security group policies, quality of service (english: quality of Service, abbreviation: qoS), firewall policies, network address translation (english: network Address Translation, abbreviation: NAT), virtual private networks (english: virtual Private Network, abbreviation: VPN), and the like.

Based on this, the network orchestration cluster needs to allocate, from among the multiple service devices of the target resource cluster, a target service device with a type matching, based on the type of the service request.

In practice, network organization clusters are isolated by using a private network (English: virtual Private Cloud, abbreviated as VPC), and each network organization cluster is respectively clustered by using an independent database (such as MySql database) and a message queue (such as RabbitMQ).

In some alternative embodiments, the network orchestration cluster receives the service requests sent by the gateway cluster through its own MQ, and sequentially obtains the service requests from the MQ.

In some alternative embodiments, after step S504 above, the network orchestration cluster further performs:

And storing the information representing the target tenant and the information representing the target business service equipment in a database of the network arrangement cluster.

That is, the network orchestration cluster performs data management independently, and ensures the data relevance of the same tenant.

Fig. 6 is an interaction flow chart of a second device allocation method according to an embodiment of the present application, as shown in fig. 6, including the following steps:

step S601: and the gateway cluster responds to a service request triggered by a target tenant, and determines whether the target tenant is contained in the tenants in the preset corresponding relationship.

The preset corresponding relation in the gateway equipment is established based on the historical service request, after the gateway equipment receives the service request triggered by the tenant for the first time, a network arrangement cluster is allocated to the tenant, the corresponding relation between the tenant and the network arrangement cluster is established, and all the service requests of the tenant are sent to the network arrangement cluster subsequently;

Based on the above, after receiving the service request triggered by the target tenant, the gateway cluster needs to determine whether the target tenant is included in the tenants in the preset corresponding relationship, if so, it indicates that the target tenant is not the first triggering service request, and network arrangement clusters have been allocated to the tenant, and needs to determine the network arrangement cluster corresponding to the target tenant from the preset corresponding relationship;

If the target tenant is not included, the target tenant is indicated to trigger a service request for the first time, network arrangement clusters are not allocated to the tenant yet, the network arrangement cluster corresponding to the target tenant needs to be selected from all network arrangement clusters based on state parameters of each network arrangement cluster, and the preset corresponding relation is updated based on the target tenant and the selected network arrangement cluster, so that all service requests triggered by the target tenant can be corresponding to the network arrangement cluster.

Step S602: if yes, determining a network arrangement cluster corresponding to the target tenant from the preset corresponding relation; otherwise, based on the state parameters of each network arrangement cluster, selecting the network arrangement cluster corresponding to the target tenant from all network arrangement clusters, and updating the preset corresponding relation based on the target tenant and the selected network arrangement cluster.

For example, the preset correspondence may be shown in the following table 1:

TABLE 1

If the target tenant is tenant 3, the tenant 3 in the preset corresponding relationship includes tenant 3, and according to the preset corresponding relationship, it can be determined that the target tenant corresponds to network orchestration cluster 1.

Taking the table 1 as an example, if the target tenant is the tenant 12, the tenant 12 is not included in the tenant in the preset corresponding relationship, and the network arrangement cluster corresponding to the tenant 12 needs to be selected from the 5 network arrangement clusters according to the state parameters of the 5 network arrangement clusters, for example, the network arrangement cluster 5 is selected as the network arrangement cluster corresponding to the tenant 12;

the preset correspondence relationship needs to be updated based on the tenant 12 and the network orchestration cluster 5, and the updated preset correspondence relationship can be shown in table 2:

TABLE 2

Network orchestration cluster 1	Tenant 1, tenant 2, tenant 3
		Network orchestration cluster 2	Tenant 4, tenant 5
Network orchestration cluster 3	Tenant 6, tenant 7
		Network orchestration cluster 4	Tenant 8, tenant 9, tenant 10
Network orchestration cluster 5	Tenant 11, tenant 12

The original preset corresponding relation and the updated preset corresponding relation are only exemplary, and the application is not limited thereto.

Step S603: and the gateway cluster sends the service request to the corresponding network arrangement cluster.

Step S604: the network arrangement cluster determines a target resource cluster corresponding to the service request.

Step S605: and the network arrangement cluster allocates target business service equipment for the target tenant from a plurality of business service equipment of the target resource cluster based on the type of the business request.

The specific implementation of steps S603 to S605 may refer to the above embodiment, and will not be described herein.

In some optional embodiments, the state parameter includes a first number and/or a second number, where the first number is a number of tenants corresponding to each network orchestration cluster, and the second number is a number of tenant service ports corresponding to each network orchestration cluster;

Correspondingly, the step S603 may be implemented by, but not limited to, the following ways:

For example, the network arrangement clusters in the resource arrangement system need to be kept in a state balance as much as possible, so that the resource waste of the network arrangement clusters is reduced, and the processing performance of the network arrangement clusters is ensured;

Based on this, when the gateway cluster allocates network orchestration clusters for the target tenant, a network orchestration cluster with a smaller number of associated tenants needs to be selected (i.e. a network orchestration cluster with a minimum first number is selected as the network orchestration cluster corresponding to the target tenant); or a network orchestration cluster with a smaller number of associated tenant traffic ports (virtual machines) (i.e. selecting the network orchestration cluster with the smallest second number as the network orchestration cluster corresponding to the target tenant); or simultaneously, the network arrangement clusters with less associated tenants and less associated tenant service ports are selected (the network arrangement cluster with the smallest weighted number is selected as the network arrangement cluster corresponding to the target tenant).

The foregoing is merely illustrative, and in practice, it is sufficient to balance the operating states of all network orchestration clusters.

Fig. 7 is an interaction flow chart of a third device allocation method according to an embodiment of the present application, as shown in fig. 7, including the following steps:

Step S701: and the gateway cluster responds to the service request triggered by the target tenant, and determines the network arrangement cluster corresponding to the target tenant based on a preset corresponding relation.

Step S702: and the gateway cluster sends the service request to the corresponding network arrangement cluster.

Step S703: the network arrangement cluster determines a target resource cluster corresponding to the service request.

The specific implementation manner of the steps S701 to S703 may refer to the above embodiment, and will not be described herein.

Step S704: and the network arrangement cluster determines candidate business service equipment corresponding to the type of the business request from a plurality of business service equipment of the target resource cluster.

In this embodiment, a resource cluster generally includes a plurality of optional devices that provide the same service; different types of service requests need to use different cloud network resources and also correspond to different service devices.

Based on this, this embodiment needs to determine candidate service devices matching the type of the service request from the target resource cluster, and then select the target service device from the candidate service devices.

Step S705: the network orchestration cluster selects the target business service device from all candidate business service devices based on the load parameters of each candidate business service device.

For example, one resource cluster generally includes a plurality of optional devices that provide the same service, where the load conditions of the plurality of optional devices are different, and in order to improve the subsequent service processing efficiency, a target service device with a smaller load needs to be selected from all candidate service devices based on the load parameters of each candidate service device.

In some alternative embodiments, this step may be accomplished by, but not limited to, the following:

In some optional embodiments, on the basis of any of the foregoing embodiments, the gateway cluster further performs the following steps:

As described above, the network orchestration clusters may be laterally expanded (i.e. the number of network orchestration clusters is increased) during use, based on which, if the number of network orchestration clusters available in the resource orchestration system is smaller than the preset number, it is indicated that the number of network orchestration clusters available in the resource orchestration system is too small, and the network orchestration clusters need to be increased in the resource orchestration system to ensure the processing performance of the network orchestration clusters, so as to provide better services for subsequent tenants;

based on the above, the message characterizing the increased network arrangement cluster needs to be notified in a preset notification manner, so that related personnel can timely learn that the available network arrangement cluster in the resource arrangement system is too few.

For example, the above-mentioned available network orchestration cluster is a network orchestration cluster with a processing performance parameter smaller than a preset parameter, that is, if the processing performance parameter of the network orchestration cluster is smaller than the preset parameter, no new tenant is associated for the network orchestration cluster.

The processing performance parameter is an index capable of representing the residual processing capacity of the network arrangement cluster, and information such as the residual memory, reading speed, CPU performance and the like of the network arrangement cluster can be comprehensively obtained.

In some alternative embodiments, after notifying the message characterizing the added network orchestration cluster by a preset notification manner, the gateway cluster further performs the following steps:

By way of example, after notifying the message characterizing the addition of the network orchestration cluster by a preset notification manner, the relevant personnel can timely learn that the available network orchestration cluster in the resource orchestration system is too few. And triggering a network arrangement cluster adding instruction carrying configuration information of the newly-added network arrangement cluster, and after receiving the network arrangement cluster adding instruction, the gateway equipment determines the configuration information of the newly-added network arrangement cluster and transversely expands the network arrangement cluster in the resource arrangement system.

In some alternative embodiments, the network orchestration cluster further performs the following steps on the basis of any of the above embodiments:

if other tenants associated with the target tenant exist, sending the arrangement data of the target tenant to a shared data unit; obtaining the arrangement data of other tenants associated with the target tenant from the shared data unit; wherein the orchestration data includes tenant information, allocated business service device information, and shared information (resources that need to be shared).

In practice, there may be allocation of shared resources among multiple tenants, such as floating IP addresses (FIPs), virtual local area network accounts (VLAN IDs), etc., which are associated with each other, but not necessarily allocated in the same network orchestration cluster;

Based on this, in this embodiment, by setting the shared data unit, the network orchestration cluster sends the orchestration data of the associated tenant to the shared data unit, and obtains the orchestration data of other tenants associated with the tenant from the shared data unit, which not only ensures the relevance of the data of the same tenant, but also ensures the relevance of the data of different tenants associated with each other.

The specific implementation manner of the shared data unit is not limited in this embodiment, and may be set in any network arrangement cluster of the resource arrangement system, or may be set in the resource arrangement system independently.

In implementation, besides the user of the tenant identity, a user of the administrator identity may also appear, and correspondingly, on the basis of any embodiment, the gateway cluster further performs the following steps:

Responding to a read request triggered by an administrator, and determining a first network arrangement cluster corresponding to the read request; after first read data is acquired from the first network arrangement cluster, the first read data is spliced to obtain first spliced data;

responding to a writing request triggered by an administrator, and determining a second network arrangement cluster corresponding to the writing request; and writing the data carried by the writing request in the second network arrangement cluster.

The administrator has the authority of reading and writing to all network arrangement clusters, so that the administrator can trigger a reading request when needing to read part or all of the data in the network arrangement clusters, and the gateway cluster acquires the first reading data from the corresponding first network arrangement cluster and performs splicing when receiving the reading request;

When the manager needs to write data in part or all of the network arrangement clusters, the manager can trigger a write request, and when the gateway cluster receives the write request, the data carried by the write request is written in the corresponding second network arrangement cluster.

In some alternative embodiments, to ensure the security of the resource orchestration system, the gateway cluster needs to authenticate the tenant, and this step may be performed by KeyStone (the unit responsible for authentication, service rules, and service tokens in the openstack framework) of the gateway cluster.

In the embodiment of the application, as shown in fig. 8, a device allocation method executed by a gateway cluster in a resource scheduling system includes the following steps:

Step S801: responding to a service request triggered by a target tenant, and determining a network arrangement cluster corresponding to the target tenant based on a preset corresponding relation; the preset corresponding relation comprises a corresponding relation between a network arrangement cluster and a tenant, and the same tenant in the preset corresponding relation corresponds to the same network arrangement cluster;

Step S802: and sending the service request to a corresponding network arrangement cluster, so that the corresponding network arrangement cluster distributes target service equipment for the target tenant from a plurality of service equipment of a target resource cluster corresponding to the service request after receiving the service request.

In some alternative embodiments, the method further comprises:
