Description

Method, device and system for managing virtual network service

The present invention relates to the field of communications, and in particular, to a method, apparatus, and system for managing a virtual network service. Background technique

With the development of cloud computing technology, Infrastructure as a Service (IAAS) services have gradually matured in business models and technologies. In IaaS services, cloud service providers provide users with virtual infrastructure services such as computing resources, storage resources, and network resources. With cloud services, users can access cloud resources that are free to change. The amount of resources is almost unlimited, and users can pay for usage after using the resources.

Virtual network services are an important part of IaaS services. The virtual network service is used to provide the services required by the user on the service. In the process of virtual network services, users need to send the requirements for network services to the cloud service provider. The cloud service provider allocates corresponding network service resources according to the needs of users and provides effective network services.

Figure 1 depicts the network architecture of an existing cloud service provider. The cloud service user 101 and the cloud service provider 102 interact with the user's requirements and instructions for the cloud service through the user interface, such as CIMI (Cloud Infrastructure Management Interface) specified by the DMTF (Distributed Management Task Force). Cloud Infrastructure Management Interface ) interface. The cloud service provider 102 can include multiple modules. One of the more popular modules is divided into: the cloud service portal 103 is responsible for interacting with the user and displaying the service, and the virtual resource management system 104 is responsible for managing and allocating the virtual resources, and Interact with the cloud service portal 103 to obtain user requirements and return corresponding results. The virtual resource management system 104 can manage a variety of resources. It includes server resources 105, network resources 106, and other resources 107. These resources may be included in the cloud service provider 102 or may be provided by other entities.

In existing cloud services, users have less control over virtual network services. In general, users can only make functional requests for the network services they need (such as firewall services, etc.). The cloud service provider configures the corresponding network service according to the functional requirements of the user. The specific process includes the steps shown in Figure 2:

Step 201: The user proposes a virtual network service requirement to the cloud service provider, where the virtual network service requirement is mainly a functional requirement, such as a firewall service and a black and white list thereof.

Step 202: The cloud service portal system forwards the user's functional requirements to the virtual resource management system.

Step 203: The virtual resource management system performs function decomposition according to the network structure of the user and the virtual network service requirement of the user, and determines the network device to be configured.

Step 204: The virtual resource management system sends the corresponding network configuration to the network device to complete the corresponding network configuration.

Step 205: The virtual resource management system sends the configuration result to the cloud service portal, and notifies the specific network service instance for subsequent modification by the user.

Step 206: The cloud service portal returns the network service instance to the user to complete the virtual network service request.

The main problems with the existing virtual network service request process are:

Users only notify the cloud service provider of the network service functions they need, and are not sure about the service performance they need.

For a particular network service, such as a firewall service, its service performance is difficult to obtain in existing configuration parameters. Although the existing network configuration includes the user's configuration of network bandwidth and quality of service (such as delay, packet loss rate, etc.). However, the performance and bandwidth requirements of specific network services are difficult to obtain from existing parameters. For example, in a firewall's bandwidth configuration, the required processing power (for responding to various types of attacks) may be much larger than the user's effective bandwidth. On the other hand, some Some specific services (such as load balancing services) may only need to process a portion of the total user traffic, which has much less processing bandwidth requirements than the total user traffic.

Based on the above situation, when the virtual resource management system cannot accurately obtain the user's demand for the performance of the network service, the virtual communication management system cannot reasonably select the specific manner of providing the network service according to the specific performance requirement.

In practical applications, the user can also provide performance requirements of the virtual network while requesting the functional requirements of the virtual network service. The virtual resource management system can flexibly select the specific way to implement the network service according to the functional requirements and performance requirements of the user's virtual network service. For example, the user sends the required functional requirements and performance requirements of the network service to the cloud service provider, and the cloud service provider selects appropriate virtual network resources according to the user's needs and provides services for the user. Specifically, the network service may include one or more of the following services: a firewall service, a traffic cleaning service, a load balancing service, a network address translation service, a quality of service control service, and a Domain Name System (DNS). Query service, Dynamic Host Configuration Protocol (DHCP).

The performance requirement may be a fixed performance requirement or a dynamic performance configuration policy. The network service may be implemented by a physical network device, a server device, or a virtual machine, or may be implemented by a combination of the foregoing devices.

The architecture of the present invention is shown in FIG. The cloud service user 101 and the cloud service provider 102 interact with the user's requirements and instructions for the cloud service through the user interface. In the process of interacting through the user interface, the cloud service user 101 reports the functional requirements and performance requirements of the required virtual network service to Cloud service provider 102. Further, the cloud service provider 102 can reasonably allocate network resources according to the functional requirements and performance requirements of the cloud service user 101, and determine the implementation manner of the virtual network service.

In FIG. 1, the virtual resource management system 104 can acquire the functional requirements and performance requirements of the user's network service; and analyze the functional requirements and performance requirements of the network service, and combine the existing virtual resources to implement the virtual network service required by the user. The logic modules depicted in Figure 1 can be merged or split as needed in actual deployment and application. For example, cloud service portal 103 and virtual resource management system 104 can be combined into one module that interacts internally using internal communication.

When a user requests an IaaS service, in addition to requesting computing resources and storage resources, it is often necessary to request virtual network resources to connect to a virtual machine provided by the cloud service provider for the user. The user's need for virtual network services can be generated in a number of ways:

For non-professional users, the network services provided in the virtual network architecture and virtual network can be generated by the system default template or several typical network architectures.

For professional users, virtual network architecture and virtual network services can be generated through user demand for the network and planning of the network topology.

When a user has a physical system implementation before migrating to a cloud service, the virtual network architecture and the virtual network service can be generated by the topology and configuration in the existing physical system.

After the user generates the requirements of the virtual network architecture and the virtual network service, specific requirements need to be sent to the cloud service provider to complete the configuration of the virtual network service. In the present invention, the virtual network service is mainly directed to the following types of network services:

Firewall service;

Traffic cleaning service;

Load balancing service;

Network address translation service;

Service quality control service;

DNS query service; DHCP month service.

The cloud service provider can provide these virtual network services by selecting the appropriate subnet or access point range based on the user's network topology.

When requesting the virtual network service, the user needs to first provide the function requirement parameter of the corresponding virtual network service. In the present invention, the function requirement parameter includes, but is not limited to:

Network service type;

That is, the type of the requested virtual network service may be one or more combinations of the above virtual network services.

Network service strategy;

The strategy that virtual network services need to follow. The content configured by this policy is different for different types of network services. For the firewall service, it can be a firewall blacklist list; for the traffic cleaning service, it can be a protocol type and a cleaning policy for cleaning; for the load balancing service, it can be a server list in the server pool, load balancing algorithm, virtual address configuration, For the network address translation service, it may be a list of address pools, a conversion policy; for a service quality service, it may be a processing strategy (label, queuing policy) of a flow corresponding to a flow feature that requires quality of service control; The DNS service can be a domain name and IP mapping table, and weight configuration. For the DHCP service, it can be a list of address pools and network configuration parameters.

Provide a range of network services;

That is, the scope of the virtual network service in the user network. The user's network topology can be divided into multiple subnets. The virtual network service requested by the user can act inside some subnets or on the access point of the subnet. The scope of providing virtual network services is the subnet or access point that describes the role of the requested virtual network service.

In the present invention, the cloud service user needs to provide the performance requirement of the corresponding network service when requesting the virtual network service, and the specific performance requirements include but are not limited to the following parameters:

The traffic that the network service needs to process;

Refers to the amount of data bandwidth that the network service needs to process, or the data that the network service needs to process. The number of packages. It is worth noting that the traffic demand of the network service is different from the user's network bandwidth. For example, the user bandwidth is 10 Mbps, but the performance requirement of the user's firewall service can be to handle 1 Gbps of traffic to deal with malicious attacks.

Required service reliability;

Refers to the robustness of network services, with continuous faultless service time, defined by average service failure time or failure recovery time.

The capacity of the required service configuration parameters;

For example, the maximum number of blacklists for the firewall, the size of the load balancing server pool, the domain name capacity of the DNS service, and the network address pool capacity in the DHCP or network address translation service.

The maximum processing delay required;

Refers to the maximum amount of delay in the processing of network services. For network services on the control plane (such as DHCP, DNS, etc.), the delay is the time elapsed between the time the request is received and the response is sent. For network services on the data side (such as address translation, firewall service, etc.), it refers to the delay caused by the processing of the data packet within the service providing entity.

The above performance requirement parameters can be specified by the user with specific values, or can be linked to the capacity of the IaaS service requested by the user through a specific performance configuration policy. For example, the performance of a specific virtual network service can vary proportionally with the number of virtual machines requested by the user, network bandwidth, and the like.

When a cloud service user requests a required virtual network service, it needs to provide both the functional requirements and performance requirements of the required virtual network service. The manner in which the functional requirements and performance requirements are specifically provided may be: The cloud service user actively sends the functional requirements and the performance requirements to the cloud service provider at the same time; or, the cloud service user sends some of the requirements to the cloud service provider, and the cloud service provider according to The resource status or default configuration returns the setting parameters of other requirements, and the two parties determine the specific functional requirements and performance requirements through negotiation; or

The cloud service user only sends some of the requirements to the cloud service provider, and the remaining parameters are set by the specified template. In the above manner, the cloud service provider can acquire the functional requirements and performance requirements of the virtual network service requested by the user. According to the above two requirements of the network service requested by the user, the cloud service provider can select a suitable way to implement the virtual network service requested by the user. The specific implementation can be:

Implemented by physical network devices;

Implemented through a specific physical server;

Implemented by assigning a virtual machine with special features;

It is realized by a combination of the above three methods.

The specific selection strategy can be determined by policies within the cloud service provider. For example, for a service with high performance and reliability, the cloud service provider can be implemented with actual physical network devices (such as physical firewall devices). For some services with less demanding performance, cloud service providers can use software to implement specific services (such as using virtual machines) to reduce the cost of network service implementation. Another benefit of using virtual machines to implement network services is that the corresponding network services can be migrated with the virtual machine and have less coupling to the underlying physical network.

After a cloud service provider assigns a user a specific resource to implement a specific network service, the user can also dynamically modify the performance or functionality of the network service according to his or her needs. One of the possible dynamic configuration methods is implemented by the foregoing specific performance configuration policy. In this case, the user does not have to explicitly describe the specific change of the network service performance, but the cloud service provider according to other needs of the user. Changes to dynamically adjust network service performance parameters based on established policies. For example, the virtual network service performance policy required by the user is proportional to the change of the number of virtual machines required. When the user changes the number of virtual machines, the cloud service provider can also dynamically change the virtual network service performance configuration of the user. And corresponding reserved resources.

Based on the above description, Figure 3 shows the overall steps for a cloud service provider to implement virtual network services in the present invention:

5301. The cloud service provider obtains the functional requirements and performance requirements of the user's network service.

5302, the cloud service provider analyzes the functional requirements and performance requirements of the network service, and concludes The existing virtual resources are combined to obtain an implementation scheme of the virtual network service.

S303. The cloud service provider manages and configures the network device or the server device according to the implementation manner, and implements the virtual network service required by the user. The cloud service provider can also dynamically modify the configuration according to user requirements.

Referring to FIG. 4 and FIG. 4, the cloud service user actively sends the functional requirements and performance requirements of the virtual network service, and the cloud service provider judges that the physical network device needs to complete the corresponding network function according to the user requirement. The process shown in Figure 4 includes the following steps:

Step 401: The user proposes a virtual network service requirement to the cloud service provider, where the virtual network service requirement includes the foregoing functional requirements and performance requirements.

Step 402: The cloud service portal system forwards the user's functional requirements and performance to the virtual resource management system.

Step 403: The virtual resource management system performs function decomposition according to the network structure of the user and the functional requirements of the virtual network service of the user, and determines the network service to be configured. At the same time, the virtual resource management system determines that the physical network device needs to be used to implement the request according to the performance requirements of the user network service.

Step 404: The virtual resource management system sends the corresponding network configuration to the physical network device, and completes the corresponding network configuration.

Step 405: The virtual resource management system sends the configuration result to the cloud service portal, and notifies the specific network service instance for subsequent modification by the user.

Step 406: The cloud service portal returns the network service instance to the user to complete the virtual network service request.

Referring to FIG. 5 and FIG. 5, the cloud service user actively sends the functional requirements and performance requirements of the virtual network service, and the cloud service provider judges that the virtual machine can be used to complete the corresponding function according to the user requirement. The process shown in Figure 5 includes the following steps:

Steps 501-502 are the same as steps 401-402 described above.

Step 503, the virtual resource management system is based on the user's network structure and the user's virtual network. The functional requirements of the service are functionally decomposed to determine the network services that need to be configured. At the same time, the virtual resource management system determines that the required virtual network service can be implemented by the virtual machine according to the performance requirements of the user network service.

Step 504: The virtual resource management system deploys virtual machine resources according to the functional requirements and performance requirements of the user's virtual network service, and runs a specific network service on the virtual machine.

Step 505: The virtual resource management system configures a specific network service running on the virtual machine according to the functional requirement of the virtual network service of the user. If necessary, configure the relevant physical network devices for network routing control.

Steps 506-507 are the same as steps 405-406 described above.

Referring to FIG. 6, in FIG. 6, the cloud service user does not explicitly specify the performance requirement in the process of requesting the virtual network service, but the cloud service provider negotiates with the user according to the current system resource status, and finally determines the user's virtual network month. Functional and performance requirements for the service. The process shown in Figure 6 includes the following steps:

Step 601: The user proposes a virtual network service requirement to the cloud service provider, where the virtual network service requirement may only include the functional requirements of the foregoing service.

Step 602: The cloud service portal system requests the virtual resource management system according to the function of the virtual network service of the user to obtain the resource condition that the current system can provide.

Step 603: The cloud service portal system determines the performance of the virtual network service that can be provided according to the current resource status of the system, and returns the corresponding default performance parameter to the cloud service user.

Note: The order of execution of steps 602-603 can be varied, and the cloud service portal system can also obtain default network service performance directly from the virtual resource management system. Another possibility is that after the default network service performance is determined, the cloud service portal system can require the virtual resource management system to reserve the corresponding resources.

Step 604: The cloud service user interacts with the cloud service provider to negotiate and determine the functional requirements and performance requirements of the final network service.

Step 605: The cloud service portal system forwards the user's functional requirements and performance requirements to the virtual resources. Source management system.

Step 606: The virtual resource management system performs function decomposition according to the network structure of the user and the functional requirements of the virtual network service of the user, and determines the network device to be configured. At the same time, the virtual resource management system judges according to the performance requirements of the user network service to determine the way to implement the request, and configures and manages the corresponding resources.

Step 607: The virtual resource management system sends the configuration result to the cloud service portal, and notifies the specific network service instance for subsequent modification by the user.

Step 608: The cloud service portal returns the network service instance to the user to complete the virtual network service request.

Referring to Figure 7, Figure 7, the cloud service user does not explicitly specify the specific requirements of the virtual network service in the process of requesting the virtual network service, but specifies a specific template. The cloud service provider determines the specific parameters of the functional requirements and performance requirements of the user's virtual network service based on the parameter configuration in the template. The process shown in Figure 7 includes the following steps:

Step 701: The user proposes a virtual network service requirement to the cloud service provider, where the user needs some functional requirements and/or partial performance requirements. At the same time, the user also specifies a template for the virtual network service, indicating that its virtual network requirements can be configured by a specific template.

Step 702: The cloud service portal system determines a functional requirement and a performance requirement of the virtual network service according to the template of the virtual network service of the user and the requirement parameter provided by the user. When the requirement parameter indicated by the user is inconsistent with the template, the cloud service portal system may take the separately indicated requirement parameter and ignore the corresponding parameter in the template. The cloud service portal system forwards the user's functional requirements and performance requirements to the virtual resource management system.

Steps 703-705 are the same as steps 606-608 previously described.

Referring to FIG. 8, in FIG. 8, the cloud service provider dynamically adjusts the virtual network service performance parameter according to the user's system status. The premise of the process shown in Figure 8 is that the virtual network service performance policy requested by the user states: The network service performance required by the user should be synchronized with the number of virtual machines required. The process shown in Figure 8 includes the following steps: Step 801: The user proposes a virtual machine quantity change requirement to the cloud service provider, and hopes to increase (or decrease) the number of virtual machines to cope with a larger service flow.

Step 802: The cloud service portal system forwards the user's virtual machine quantity change request to the virtual resource management system.

Step 803: The virtual resource management system confirms the change in the number of virtual machines of the user, and performs a corresponding virtual machine management, allocation, and deployment process. At the same time, the virtual resource management system determines the performance of the virtual network service required by the user through the pre-configured virtual network service performance policy, and also needs to change with the number of virtual machines. The virtual resource management system updates the performance parameters of the virtual network service required by the user.

Step 804: The virtual resource management system reconfigures the virtual network service to meet the performance requirements of the user.

Step 805: The virtual resource management system returns the execution result of the reconfiguration to the cloud service portal system, where the modification result of the virtual network service may or may not be included.

Step 806, the cloud service portal system returns the execution result to the user, where the modification result of the virtual network service may or may not be included.

In summary, the method for managing a virtual network service of the present invention, whether it is a method, a device, or a system, can acquire the functional requirements and performance requirements of the user's network service by the cloud service provider; the functional requirements of the cloud service provider for the network service The performance requirement is analyzed, and the virtual network service implementation scheme is obtained by combining the existing virtual resources; the cloud service provider manages and configures the network device or the server device according to the implementation scheme, and implements the virtual network service required by the user.
