Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 shows a network architecture provided in an embodiment of the present application. As shown in fig. 1, the operator network is hierarchically divided into a multi-domain controller 100, a single-domain controller 200, and a network element (not shown). The operator network is divided into a plurality of domains 300 according to controllers, each domain 300 corresponds to one single domain controller 200, each single domain controller 200 controls network elements in the domain 300, and a plurality of single domain controllers 200 are controlled by one multi-domain controller 100.

Illustratively, the network elements in each domain 300 include PE (provider edge) devices and P (provider network backbone) devices. The PE device is, for example, an edge router of the operator network, and has an interface connected to a CE (customer edge) device, the PE device is responsible for accessing services, and the P device is, for example, a backbone router in the operator network. The CE device is, for example, a router or a switch, or a host. The CE device is directly connected to the PE device in the domain.

In a possible implementation, one end-to-end service is a cross-domain service, that is, a user accesses from PE devices of different domains. That is, cross-domain services traverse at least two different domains. The multiple different domains through which the cross-domain service passes may be located in different countries, provinces, or cities, the vendors of equipment used by the various domains may be different, and the technologies used by the various domains may also be different. In the embodiment of the present application, the device used by the domain mainly refers to a single domain controller.

For example, as shown in fig. 1, an end-to-end service 1 passes through three domains, domain C, domain a, and domain D, and an end-to-end service 2 passes through three domains, domain C, domain B, and domain D. The domain a adopts the equipment of the manufacturer a, the domain B adopts the equipment of the manufacturer B, the domain C adopts the equipment of the manufacturer C, and the domain D adopts the equipment of the manufacturer D, and thus, it can be seen that the manufacturers of the equipment used by the domains related to the two end-to-end services are different. In addition, the domain a and the domain B use an IP CORE (CORE network) technology, the domain C uses an OTN (optical transport network) metropolitan area network technology, and the domain D uses an IP metropolitan area network technology, which means that the technologies used in the domains related to the two end-to-end services are different. Here, the domains refer to physical domains, i.e., domains existing in an actual network.

In another possible implementation, an end-to-end service is a single domain service, that is, a user accesses from different PE devices in the same domain.

In the embodiment of the present application, the service includes, but is not limited to, a VPN (virtual private network) service, a native ethernet (native ethernet) service, an SNC (sub-network connection) service, and the like. Hereinafter, the VPN service will be described in detail as an example.

Fig. 2 shows a deployment process of an end-to-end service. As shown in fig. 2, the deployment process is as follows:

201: and the generation device of the service template acquires the instantiated service template.

The instantiated service template is generated based on service characteristics of the end-to-end service and network characteristics of the network in which the end-to-end service is deployed.

202: and importing the instantiated service template by the multi-domain controller.

Alternatively, the multi-domain controller can store the imported instantiated service templates in its own service template library in a centralized manner.

203: and the multi-domain controller decomposes the end-to-end service into single-domain service according to the service template.

For example, the multi-domain controller obtains basic information of the end-to-end service, such as a boundary point (i.e., an access point of a user), a selected service template, and the like, through the input device, and decomposes the end-to-end service into single-domain services, i.e., segmented services of each single domain, according to the service template.

204: and the multi-domain controller transmits the single-domain service to the single-domain controller.

For example, the multi-domain controller issues the single-domain service to the single-domain controller through an Application Programming Interface (API).

205: the single domain controller decomposes the single domain service into a single station configuration.

Here, a station refers to a network element in a domain to which a single domain controller belongs, and a single station configuration is a configuration of each network element. Illustratively, the single domain controller decomposes the single domain service into the configuration of each network element according to the type of each network element in the domain to which the single domain controller belongs.

206: and the single-domain controller transmits the single-station configuration to the corresponding network element.

In this way, the configuration of each network element is issued to the corresponding network element, so that the network bears the service according to the configuration of the network, namely the service is deployed in the network.

It can be seen that the service design template is crucial to the deployment of services in the network.

Fig. 3 is a flowchart of a method for generating a service template according to an embodiment of the present application. The method is executed by computer equipment, and when the service design template generated by the service template generation method is suitable for cross-domain services, the computer equipment is a multi-domain controller or newly added equipment except the multi-domain controller. When the service design template generated by the service template generation method is suitable for single-domain services, the computer equipment is a single-domain controller or newly added equipment except the single-domain controller. Referring to fig. 3, the method includes several processes as follows.

301: and acquiring service characteristics and network characteristics.

The service features are used to describe the service. The service features include, but are not limited to: traffic type, traffic policy, traffic parameters, domain connection policy, etc.

The service types include L2VPN service, L3VPN service, client (client) service of OTN, and the like. The traffic policy includes, but is not limited to, an address pool policy, a quality of service (Qos) policy, a protection policy, and a routing policy, etc. The service parameters include, but are not limited to, bandwidth information and SLA (service-level aggregation) parameters, among others. The domain connection policy includes, but is not limited to, VLAN (virtual local area network) interfacing, ODUk (optical channel data unit-k) interfacing, and the like.

In the embodiment of the present application, the service type in the service feature refers to a service type of an end-to-end service. For example, the end-to-end traffic is combined VPN traffic. The combined VPN service is formed by combining one or more segmented VPN services, and each segmented VPN service corresponds to a single-domain service in one domain. In a combined VPN service of a specific service type, as long as one segmented VPN service is the specific service type, the service types of the remaining segmented VPN services are the specific service type or other service types other than the specific service type. For example, a three-layer combined VPN service includes a plurality of segment VPN services, where the segment VPN services at least include an L3VPN service, and other segment VPN services are an L2VPN service, a Client service, and the like.

Network features are used to describe the network carrying the traffic, mainly to describe the characteristics of the devices in the network topology. Network characteristics include, but are not limited to, physical domain identification, device vendor information, device version information, and the like. In this embodiment, the network includes at least one physical domain, each physical domain corresponding to a single domain controller. The characteristics of the devices described by the network features mainly refer to the characteristics of the single domain controllers in the respective physical domains.

In other embodiments, the network may be divided into a plurality of sub-networks, each sub-network comprising at least one physical domain, each physical domain corresponding to a single domain controller, the single domain controllers in each sub-network being controlled by a multi-domain controller, in which case the characteristics of the devices described by the network characteristics include the characteristics of the multi-domain controllers corresponding to the respective sub-network and the characteristics of the single domain controllers in the respective sub-network. That is, the method provided by the embodiment of the present application is applicable to a network of more layers in addition to the 3-layer network in fig. 1.

Illustratively, the service characteristics are obtained via an input device. The network characteristics are obtained through an input device or, alternatively, from a multi-domain controller. The acquired service characteristics and network characteristics each include at least one characteristic.

302: and determining a target virtual service design template from the virtual service design template library according to the service characteristics and the network characteristics.

Illustratively, the virtual business design template library includes at least one first virtual business design template. Here, the virtual service design template library is preset before executing the method of the embodiment of the present application, and the first virtual service design template in the virtual service design template library may be obtained in at least one of the following manners: one is manual configuration, and the other is abstracted through instantiated service templates, and the abstracting manner can be referred to in the following 307-308, and detailed description is omitted here.

Each first virtual business design template includes a feature set including a plurality of features. These characteristics include at least one of the following information: information of the virtual domain; connection relations between virtual domains; service configuration of each virtual domain; and (5) decomposing the strategy.

The virtual domain is an abstract subnet, and the information of the virtual domain includes a series of device feature sets, such as device manufacturers, device versions, and the like, for matching the network topology.

The connection relationship between virtual domains is a connection protocol between two adjacent domains when the service spans two or more domains, such as VLAN docking and the like.

The service configuration of each virtual domain mainly includes a service type and a default configuration of the service type, such as a signal type of a Client service, a VRRP (virtual router redundancy protocol) switch of an L3VPN, and the like.

The resolution policy includes, but is not limited to, a resource policy that requires automatic allocation. Such as RD (route-distinguisher)/RT (route-target) allocation policy, Qos package policy, etc., of the hubsspoke-type VPN. If the first virtual service design template comprises at least two virtual domains, the decomposition strategy comprises an inter-domain decomposition strategy between the at least two virtual domains and an intra-domain decomposition strategy in each virtual domain. If the first virtual service design template only comprises one virtual domain, the decomposition strategy only comprises an intra-domain decomposition strategy in the virtual domain.

And the connection relation among the virtual domains, the service configuration of each virtual domain and the decomposition strategy form a service characteristic set. And the union of the service characteristic set and the equipment characteristic set is the characteristic set of the first virtual service design template.

In different first virtual service design templates, at least one of information of virtual domains, connection relations among the virtual domains, service configuration of the virtual domains and a decomposition strategy is different. Here, at least one means at least one of any one of the four kinds of information.

In the embodiment of the present application, each virtual domain corresponds to one service type, for example, corresponds to L3VPN or L2 VPN. Each virtual domain has a unique identity and a device feature set describing the smallest features that can distinguish different devices, where the smallest features are the aforementioned device vendor, device version.

In a possible implementation manner, the device feature set corresponding to the virtual domain is valid in one virtual service design template, for example, each virtual service design template includes all information of the virtual domain. In another possible implementation, the device feature set corresponding to the virtual domain is valid across templates, for example, the device feature set corresponding to the virtual domain is separately stored, a plurality of virtual service design templates include the same identifier of the virtual domain, and the plurality of virtual service design templates can call the device feature set of the corresponding virtual domain through the identifier of the virtual domain.

Illustratively, determining a target virtual business design template from a library of virtual business design templates based on the business characteristics and the network characteristics comprises: matching the service characteristics and the network characteristics with the characteristics in the characteristic set to obtain the matching degree of each first virtual service design template; and determining a target virtual service design template from each first virtual service design template according to the matching degree.

Exemplarily, matching the service features and the network features with the features in the feature set to obtain the matching degree of each first virtual service design template, including: for any one first virtual service design template, at least part of the service characteristics and the network characteristics are respectively matched with the characteristics in the characteristic set; and determining the matching degree of the first virtual service design template according to the weight corresponding to the matched features.

The weight corresponding to the features is determined according to the importance degree of meeting the customer appeal after the service is deployed, so that the higher the probability of meeting the customer appeal is, the higher the matching degree of the first virtual service design template corresponding to the service deployment mode is.

There are various ways to match the service features and the network features with the features in the feature set, as long as at least part of the service features and the network features can be matched with the features in the feature set respectively. The matching method includes, but is not limited to, the following two.

The first matching mode is as follows:

for each first virtual service design template, matching the service features and the network features with the features in the feature set according to the sequence of the priority of the service features and the priority of the features in the network features from high to low until the service features and the network features with the specified priorities are matched; and determining the matching degree of the first virtual service design template according to the weight corresponding to the matched features.

The matching degree of the first virtual service design template is positively correlated with the weighted average of the weights corresponding to the finally matched features, the larger the weighted average is, the higher the matching degree of the first virtual service design template is, and the largest weighted average is the first virtual service design template with the highest matching degree.

In a possible implementation manner, the priority of the feature corresponds to the type of the feature, and the obtained priority of the network feature and the service feature is determined according to the relationship between the type of the feature and the priority. The assigned priority is set according to actual needs, for example, the assigned priority is the lowest priority, or the assigned priority is an intermediate priority determined by integrating the matching efficiency and the matching accuracy.

Here, higher priority indicates higher probability that the service deployment meets the customer appeal, and meanwhile, higher priority of a feature increases the weight corresponding to the feature. For example, the device vendor, device version, and service type are higher in priority, and the resolution policy is lower in priority. Matching is carried out according to the priority, so that the complexity of the matching process can be reduced, and the matching efficiency can be improved.

In other embodiments, matching according to the priority of the features from high to low is replaced by matching according to the priority of the features from low to high, which is not limited in this application.

This matching method is exemplified below.

In fig. 1, the service type of the end-to-end service 1 is an L3VPN service, and covers three physical domains, namely, a domain C, a domain a, and a domain D, where the device of the domain C is a device of a manufacturer C, the version is 3, the device of the domain a is a device of the manufacturer a, the version is 1, the device of the domain D is a device of the manufacturer D, and the version is 3. As described above, for the combined VPN service, it is only necessary that the service type of one of the domain C, the domain a, and the domain D is the L3VPN service.

The input service features include service types: l3VPN, service policy: protection policy, network characteristics: manufacturer C, version 3; manufacturer a, version 1; manufacturer D, version 3.

The first virtual service design module comprises a feature set { [ virtual domain a, manufacturer A, version 1], [ virtual domain B, manufacturer B, version 3], [ VLAN docking ], [ L3VPN, configuration 1], [ decomposition policy 1] }, wherein [ virtual domain a, manufacturer A, version 1], [ virtual domain B, manufacturer B, version 3] is information of the virtual domain, [ VLAN docking ] is an inter-domain connection policy, [ L3VPN, configuration 1] is service configuration, and [ decomposition policy 1] is a decomposition policy.

The second virtual service design module comprises a feature set { [ virtual domain a, manufacturer a, version 1], [ virtual domain B, manufacturer D, version 3], [ VLAN docking ], [ L3VPN, configuration 1], [ decomposition policy 2] }, wherein [ virtual domain a, manufacturer a, version 1], [ virtual domain B, manufacturer B, version 3] is information of the virtual domain, [ VLAN docking ] is an inter-domain connection policy, [ L3VPN, configuration 1] is service configuration, and [ decomposition policy 2] is decomposition policy.

According to a first matching mode:

the priority of the traffic type is highest, the priority of the network characteristics is second, and the priority of the traffic policy is lowest. Matching is carried out according to the priority from high to low, and only the characteristics of the first two priorities are matched.

Characteristic of the first priority: traffic type L3VPN, weight 100. Feature of the second priority: network characteristics, weight 100. Since the network includes three physical domains, the weight fraction of each physical domain is 1/3.

First, the characteristics of the first priority are matched, and the two first virtual service design templates are matched. Then, matching the characteristics of the second priority, wherein only the virtual domain a of the first virtual service design template can correspond to the physical domain and has the weight of 100 × 1/3, the second first virtual service design template can match two virtual domains and has the weight of 100 × 2/3, the weight of the second first virtual service template is 100+100 × 2/3, and the weight of the first virtual service template is as follows: 100+100 × 1/3, the second first virtual traffic template has a higher degree of matching.

The second matching mode is as follows:

matching the network characteristics with the equipment characteristic set in the first virtual service design template to obtain a first matching degree; matching the service characteristics with a service characteristic set in the first virtual service design template to obtain a second matching degree; and obtaining the matching degree of the first virtual service design template according to the first matching degree and the second matching degree.

In a possible implementation manner, matching the network feature with the device feature set in the first virtual service design template to obtain a first matching degree includes: determining the device characteristics matched with the network characteristics in the device characteristic set; and taking the sum of the weights corresponding to the determined equipment features as a first matching degree.

Similarly, matching the service characteristics with the service characteristic set in the first virtual service design template to obtain a second matching degree, including: determining the equipment characteristics matched with the service characteristics in the service characteristic set; and taking the sum of the weights corresponding to the determined service characteristics as a second matching degree.

Different kinds of network characteristics and service characteristics are respectively preset with weights, the weights are positively correlated with the importance degrees of the corresponding network characteristics and service characteristics to service deployment, namely, the more important the network characteristics and the service characteristics to service deployment, the larger the corresponding weights. For example, in the embodiment of the present application, the device manufacturer, the device version, and the service type are most important for service deployment, and the weighted values corresponding to the device manufacturer, the device version, and the service type are equal and maximum.

In one possible implementation manner, the sum of the first matching degree and the second matching degree is used as the matching degree of the first virtual service design template.

In the two matching methods, matching refers to searching for the same feature in the feature set, and if the same feature exists in the feature set, it indicates that there is a matched feature.

In a possible implementation manner, determining a target virtual service design template according to the matching degree includes: and taking the first virtual service design template with the highest matching degree as a target virtual service design template. That is, the default target virtual service design template is the first virtual service design template with the highest matching degree.

In another possible implementation, determining a target virtual service design template according to the matching degree includes: sequencing the first virtual service design templates according to the sequence of the matching degree from high to low; displaying a plurality of first virtual service design templates arranged in front; and selecting a target virtual service design template from the plurality of first virtual service design templates according to a user instruction. Illustratively, the number of the first virtual business design templates shown is a set value, for example, 5, etc.

Illustratively, among the displayed plurality of first virtual business design templates, the first virtual business design template corresponding to the business design template with the least modification required after instantiation is selected as the target virtual business design template.

303: and generating an instantiated service template according to the target virtual service design template.

The instantiated traffic template is used to configure the network such that the network carries the traffic, i.e. the traffic is deployed in the network. The configuration of the network is completed, for example, according to the flow shown in fig. 2.

Illustratively, 303 includes:

3031: and extracting network characteristics of a physical domain in the network, including equipment manufacturers, equipment versions and the like.

3032: in the target virtual service design template, a first virtual domain with an equivalent physical domain is determined, wherein the equivalent physical domain is a physical domain with the same network characteristics as the corresponding first virtual domain.

3033: and replacing the identifier of the first virtual domain in the target virtual service design template with the identifier of the equivalent physical domain. And copying the configuration corresponding to the virtual domain to the physical domain to obtain the instantiated service template.

Optionally, if there is a second virtual domain without an equivalent physical domain in the target virtual service design template, 303 further includes: and deleting the second virtual domain and the service characteristics corresponding to the second virtual domain.

For example, three virtual domains are deployed in the target virtual service design template, where a virtual domain a employs a device of a manufacturer a, a virtual domain B employs a device of a manufacturer B, a virtual domain C employs a device of a manufacturer C, and the physical domains only include a physical domain employing the device of the manufacturer a and a physical domain employing the device of the manufacturer B, and at this time, it indicates that there is no equivalent physical domain in the virtual domain C in the target virtual service design template, and therefore, relevant content of the virtual domain C in the target virtual service design template is deleted.

In one possible implementation, the matching degree between the physical domain in the physical network and the virtual domain in the target virtual service design template is high, for example, each physical domain has an equivalent virtual domain in the target virtual service design template, in this case, the instantiated service template is obtained directly by converting according to the target service design template, and the execution 304 is not needed.

In another possible embodiment, the matching degree between the physical domain in the physical network and the virtual domain in the target virtual service design template is relatively low, for example, part of the physical domain in the physical network does not have an equivalent virtual domain in the target virtual service design template, in this case, an instantiated service template matching the existing network cannot be directly converted according to the target virtual service design template, and therefore, the method further includes:

304: and modifying the instantiated service template according to the received instruction.

Modifying the instantiated business template, including at least one of:

adding a physical domain and service characteristics corresponding to the physical domain;

deleting the physical domain and the service characteristics corresponding to the physical domain;

and modifying the service characteristics corresponding to the physical domain.

Accordingly, the received instruction includes at least one of an add instruction, a delete instruction, and a modify instruction.

Here, adding a physical domain includes adding a physical domain identification and features of devices within the physical domain. Deleting the physical domain includes deleting the physical domain identification and the characteristics of the device within the physical domain. The service features are features in the service feature set.

Optionally, to ensure reliability after the service configuration, before configuring the network by using the instantiated service template, the method further includes:

305: and verifying the instantiated business template.

Illustratively, the verification means includes:

determining a boundary point of a service, wherein the boundary point is an access point of a tenant, namely accessed PE equipment;

determining the configuration on the boundary points and the paths between the boundary points according to the boundary points of the services and the instantiated service templates, wherein the paths between the boundary points comprise network elements through which the services pass;

and comparing the determined configuration with the reference configuration to obtain a verification result.

Here, if the determined configuration is the same as the reference configuration, the verification result is a pass verification; if the determined configuration is different from the reference configuration (including partially or totally different), the verification result is not verified.

Illustratively, the boundary points of the traffic are obtained by the input means. The configuration comprises at least one of a configuration command line and a configuration parameter. Illustratively, the reference configuration is also obtained by an input device, entered by a technician.

In one possible implementation, the verification result is obtained by manually checking whether the determined configuration meets the requirements.

In the case that an instantiated business template is not validated, the technician needs to further modify and validate the instantiated business template until the instantiated business template is validated.

Here, according to the boundary point and the instantiated service template, the process of determining the configuration command of the boundary point is the same as the process of determining the network configuration by the actual multi-domain controller and single-domain controller, but the obtained configuration is only used for verifying the instantiated service template and is not issued to the network.

Optionally, in some embodiments, the instantiated service template is not verified, and the service deployment is performed directly according to the instantiated service template.

306: and saving the instantiated business template which passes the verification.

For example, the instantiated business template that passes the validation is saved in a business template library. The instantiated service templates are stored in a centralized manner by using the service template library, so that unified management can be conveniently performed on the instantiated service templates, for example, full-life-cycle management can be performed on the instantiated service templates in the service template library according to actual needs, such as importing, exporting, publishing, unpublishing, deleting and the like.

In one possible embodiment, if the instantiated service template is not directly transformed from the target virtual service design template, but is a modified service template, the instantiated service template can be abstracted to obtain a new virtual service design template. The instantiated service template is abstracted to obtain a corresponding second virtual service design template, the second virtual service design template is used as a new first virtual service design template and added into the virtual service design template library, and the virtual service design templates in the virtual service design template library can be added in a self-learning mode, so that the possibility that the target virtual service design template is possibly matched during subsequent service deployment is increased. In this case, the method further comprises:

307: and generating a second virtual business design template according to the instantiated business template.

308: and adding the second virtual service design template into the virtual service design template library.

Illustratively, 307 is implemented by:

3071: and extracting the characteristic parameters of the physical domain in the instantiated service template to obtain the characteristic parameter set of each physical domain, wherein the characteristic parameter set comprises the equipment manufacturer, the equipment version and the connection relation of the physical domain in the physical domain.

3072: and deleting the physical domain with the same characteristic parameter set and the corresponding service configuration.

3073: and replacing the identifier of each physical domain in the instantiated service template with the identifier of a unique virtual domain to generate a second virtual service design template.

And deleting the physical domain with the same characteristic parameter set and the corresponding service configuration to reduce the repeated content in the obtained second virtual service design template so as to simplify the second virtual service design template.

It should be noted that if the instantiated service template is directly converted from the target virtual service design template, and is not modified, the steps 307 to 308 do not need to be executed.

In another possible implementation, a new virtual business design template is added to the virtual business design template library through a manual configuration mode. For example, according to expert experience, a plurality of virtual business design templates are generated and added into the virtual business design template library.

Through the self-learning and manual configuration modes, the virtual service design templates in the virtual service design template library can be updated, the more the virtual service design templates in the virtual service design template library are, the higher the possibility that the subsequent service can be matched with the target service design template is, and the automatic generation of the instantiated service template is facilitated.
