业务模板的生成方法、装置、设备及存储介质
本申请要求于2020年07月22日提交的申请号为202010711021.X、发明名称为“业务模板的生成方法、装置、设备及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及网络技术领域，特别涉及一种业务模板的生成方法、装置、设备及存储介质。
背景技术
随着网络技术的发展，运营商网络复杂度指数级上升，端到端业务往往需要跨多个域。不同的域可能采用不同厂家的设备或者同一厂家但不同版本的设备，使得不同的域内的设备的能力不同，此外，不同的域还可能采用不同技术，因此，端到端业务的部署较为困难。
相关技术中，端到端业务从设计到上线通常需要经过可销售业务设计、现网硬件版本能力分析、网络配置规则设计以及将设计好的网络配置规则导入自动化系统的过程。其中，将网络配置规则导入自动化系统通常是采用现场定制的方式，对网络配置规则进行业务编排，得到自动化的业务模板，然后将业务模板导入该业务对应的多域控制器，由多域控制器根据该业务模板进行网络配置。
对于复杂度较高的网络，完成一种端到端业务的网络配置规则设计需要技术人员掌握在网设备的所有配置方式和约束，为每个域中的设备设计好网络配置规则，实现难度较高，对技术人员的技能要求高并且消耗时间很长。此外，根据网络配置规则现场定制得到业务模板，消耗的时间较长，效率较低。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
图1显示了本申请实施例提供的一种网络架构。如图1所示，运营商网络按层次分为多域控制器100、单域控制器200和网元(图未示)。该运营商网络按照控制器划分为多个域300，每个域300对应一个单域控制器200，每个单域控制器200控制所属域300内的网元，多个单域控制器200由一个多域控制器100控制。
示例性地，每个域300中的网元包括PE(provider edge，运营商网络边缘)设备和P(provider，运营商网络骨干)设备。PE设备例如是运营商网络的边缘路由器，具有与CE(customer edge，用户网络边缘)设备连接的接口，PE设备负责接入业务，P设备例如是运营商网络中的骨干路由器。CE设备例如是路由器或交换机，或者是一台主机。CE设备与域中的PE设备直接连接。
在一种可能的实施方式中，一条端到端业务为跨域业务，即用户从不同域的PE设备接入。也即是，跨域业务至少经过两个不同的域。跨域业务经过的多个不同域可能位于不同的国家、省份或城市，各个域使用的设备的厂家可能不同，并且各个域使用的技术也可能不同。在本申请实施例中，域使用的设备主要是指单域控制器。
例如图1所示，端到端业务1经过域C、域A和域D三个域，端到端业务2经过域C、域B和域D三个域。其中，域A采用厂家A的设备，域B采用厂家B的设备，域C采用厂家C的设备，域D采用厂家D的设备，可见，这两条端到端业务涉及的各个域使用的设备的厂家不同。此外，域A和域B采用的是IP CORE(核心网)技术，域C采用的是OTN(optical  transport network，光传送网)城域网技术，域D采用的是IP城域网技术，可见，这两条端到端业务涉及的各个域使用的技术也不相同。这里，域指的均为物理域，即实际网络中存在的域。
在另一种可能的实施方式中，一条端到端业务为单域业务，即用户从同一个域的不同PE设备接入。
在本申请实施例中，业务包括但不限于VPN(virtual private network，虚拟专用网络)业务、原生以太网(native ethernet)业务、SNC(sub-network connection，子网络连接)业务等等。下文中，将VPN业务为例进行详细说明。
图2显示了一条端到端业务的部署过程。如图2所示，该部署过程如下：
201：业务模板的生成装置获取实例化的业务模板。
该实例化的业务模板是根据端到端业务的业务特征、以及部署该端到端业务的网络的网络特征生成的。
202：多域控制器导入实例化的业务模板。
可选地，多域控制器可以将导入的实例化的业务模板集中保存在自身的业务模板库中。
203：多域控制器根据业务模板，将端到端业务分解为单域业务。
例如，多域控制器通过输入装置获得端到端业务的基本信息，例如边界点(即用户的接入点)、选择的业务模板等，并根据业务模板将端到端业务分解为单域业务，即各单域的分段业务。
204：多域控制器将单域业务下发给单域控制器。
例如，多域控制器通过API(application programming interface，应用程序接口)将单域业务下发给单域控制器。
205：单域控制器将单域业务分解为单站配置。
这里，站指单域控制器所属域内的网元，单站配置即为每个网元的配置。示例性地，单域控制器根据所属的域内的各个网元的类型，将单域业务分解为每个网元的配置。
206：单域控制器将单站配置下发给对应的网元。
这样，将各个网元的配置下发给对应的网元，从而实现根据对网络的配置，使得该网络承载该业务，即在网络中部署该业务。
可见，业务设计模板对业务在网络中的部署至关重要。
图3是本申请实施例提供的一种业务模板的生成方法的流程图。该方法由计算机设备执行，当该业务模板的生成方法生成的业务设计模板适用于跨域业务时，计算机设备为多域控制器，或者为多域控制器以外的新增设备。当该业务模板的生成方法生成的业务设计模板适用于单域业务时，计算机设备为单域控制器，或者为单域控制器以外的新增设备。参见图3，该方法包括如下几个过程。
301：获取业务特征和网络特征。
业务特征用于描述业务。业务特征包括但不限于：业务类型、业务策略、业务参数、域连接策略等等。
其中，业务类型包括L2VPN业务、L3VPN业务、OTN的客户(client)业务等。业务策略包括但不限于地址池策略、Qos(quality of service，服务质量)策略、保护策略和路由策略等等。业务参数包括但不限于带宽信息和SLA(service-level agreement，服务等级协议)参 数等等。域连接策略包括但不限于VLAN(virtual local area network，虚拟局域网)对接、ODUk(optical channel data unit-k，光通路数据单元)对接等等。
在本申请实施例中，业务特征中的业务类型指端到端业务的业务类型。例如，端到端业务为组合VPN业务。组合VPN业务由一个或多个分段VPN业务组合而成，每个分段VPN业务对应一个域内的单域业务。在一个特定业务类型的组合VPN业务中，只要一个分段VPN业务为该特定业务类型即可，其余分段VPN业务的业务类型是该特定业务类型，或者该特定业务类型以外的其他业务类型。例如，一个三层组合VPN业务包括多个分段VPN业务，这多个分段VPN业务中，至少包括一个L3VPN业务，其他分段VPN业务为L2VPN业务、Client业务等。
网络特征用于描述承载业务的网络，主要用于描述网络拓扑中的设备的特性。网络特征包括但不限于物理域标识、设备厂家信息、设备版本信息等。在本实施例中，网络包括至少一个物理域，每个物理域对应一个单域控制器。网络特征所描述的设备的特性主要是指各个物理域中单域控制器的特性。
在其他实施例中，网络可以分为多个子网络，每个子网络包括至少一个物理域，每个物理域对应一个单域控制器，每个子网络中的单域控制器由一个多域控制器控制，在这种情况下，网络特征所描述的设备的特性，包括各个子网络对应的多域控制器的特性以及各个子网络中单域控制器的特性。也就是说，本申请实施例提供的方法除了适用于图1中的3层次的网络，还适用于更多层次的网络。
示例性地，业务特征通过输入装置获取。网络特征通过输入装置获取，或者，从多域控制器获取。获取到的业务特征和网络特征均包括至少一个特征。
302：根据业务特征和网络特征，从虚拟业务设计模板库中，确定目标虚拟业务设计模板。
示例性地，虚拟业务设计模板库中包括至少一个第一虚拟业务设计模板。这里，虚拟业务设计模板库是在执行本申请实施例的方法之前预先设置的，虚拟业务设计模板库中的第一虚拟业务设计模板可以采用以下方式中的至少一种获得：一种是人工配置，另一种是通过实例化的业务模板抽象化得到，抽象化的方式可以参见下文中307～308相关内容，在此省略详细描述。
每个第一虚拟业务设计模板包括一个特征集合，该特征集合中包括多个特征。这些特征包括以下信息中的至少一种：虚拟域的信息；虚拟域之间的连接关系；每个虚拟域的业务配置；分解策略。
其中，虚拟域是一个抽象的子网，虚拟域的信息包括一系列的设备特征集合，例如，设备厂家、设备版本等，用于匹配网络拓扑。
虚拟域之间的连接关系，是描述业务在跨两个或多个域时的相邻的两个域之间的连接协议，例如VLAN对接等。
每个虚拟域的业务配置主要包括业务类型以及业务类型的默认配置，例如Client业务的signal type(信号类型)，L3VPN的VRRP(virtual router redundancy protocol，虚拟路由冗余协议)开关等。
分解策略包括但不限于需要自动分配的资源策略。例如Hubspoke类型的VPN的RD(route-distinguisher，路由区分器)/RT(route-target，路由标记)分配策略，Qos套餐策略等。若该第一虚拟业务设计模板包括至少两个虚拟域，则分解策略包括至少两个虚拟域之间的域 间分解策略以及每个虚拟域内的域内分解策略。若该第一虚拟业务设计模板仅包括一个虚拟域，则分解策略仅包括虚拟域内的域内分解策略。
虚拟域之间的连接关系、每个虚拟域的业务配置和分解策略组成一个业务特征集合。业务特征集合和设备特征集合的并集，即为第一虚拟业务设计模板的特征集合。
不同的第一虚拟业务设计模板中，虚拟域的信息、虚拟域之间的连接关系、虚拟域的业务配置和分解策略中至少一个有所不同。这里，至少一个是指这四种信息中的任意一种信息中的至少一个。
在本申请实施例中，每个虚拟域对应一种业务类型，例如，对应L3VPN或者L2VPN。每个虚拟域均具有唯一的标识和设备特征集合，该设备特征集合描述了能区分不同的设备的最小特征，这里，最小特征即前述设备厂家、设备版本。
在一种可能的实现方式中，虚拟域对应的设备特征集合在一个虚拟业务设计模板内有效，例如，每个虚拟业务设计模板中均包括虚拟域的所有信息。在另一种可能的实施方式中，虚拟域对应的设备特征集合跨模板有效，例如，虚拟域对应的设备特征集合单独保存，多个虚拟业务设计模板中包括相同的虚拟域的标识，这多个虚拟业务设计模板均能够通过该虚拟域的标识调用对应的虚拟域的设备特征集合。
示例性地，根据业务特征和网络特征，从虚拟业务设计模板库中确定目标虚拟业务设计模板，包括：将业务特征和网络特征与特征集合中的特征进行匹配，得到各个第一虚拟业务设计模板的匹配度；根据匹配度，从各个第一虚拟业务设计模板中确定目标虚拟业务设计模板。
示例性地，将业务特征和网络特征与特征集合中的特征进行匹配，得到各个第一虚拟业务设计模板的匹配度，包括：对于任一所述第一虚拟业务设计模板，将业务特征和网络特征中的至少部分特征，分别与特征集合中的特征进行匹配；按照匹配到的特征对应的权重，确定第一虚拟业务设计模板的匹配度。
其中，特征对应的权重根据对于业务部署后满足客户诉求的重要程度来确定，使得满足客户诉求的概率越高的业务部署方式对应的第一虚拟业务设计模板的匹配度越高。
将业务特征和网络特征与特征集合中的特征进行匹配的方式有多种，只要能够将业务特征和网络特征中的至少部分特征，分别与特征集合中的特征进行匹配即可。匹配方式包括但不限于以下两种。
第一种匹配方式：
对于每个第一虚拟业务设计模板，按照业务特征和网络特征中特征的优先级从高到低的顺序，将业务特征和网络特征与特征集合中的特征进行匹配，直至指定优先级的业务特征和网络特征均完成匹配；按照匹配到的特征对应的权重，确定第一虚拟业务设计模板的匹配度。
第一虚拟业务设计模板的匹配度与最终匹配到的特征对应的权重的加权平均值正相关，加权平均值越大，第一虚拟业务设计模板的匹配度越高，加权平均值最大的为匹配度最高的第一虚拟业务设计模板。
在一种可能的实施方式中，特征的优先级与特征的类型对应，获取到的网络特征和业务特征的优先级根据特征的类型与优先级的关系确定。指定优先级根据实际需要设置，例如，指定优先级是最低优先级，或者，指定优先级是综合匹配效率和匹配准确度确定的中间优先级。
这里，优先级越高表示业务部署满足客户诉求的概率越高，同时，特征的优先级越高，该特征对应的权重越大。例如，设备厂家、设备版本和业务类型的优先级较高，分解策略的优先级较低。根据优先级来进行匹配，可以降低匹配过程的复杂度，有利于提高匹配效率。
在其他实施例中，按照特征优先级从高到低的顺序进行匹配替换为按照特征优先级从低到高的顺序进行匹配，本申请对此不做限制。
下面对该匹配方式进行举例说明。
图1中，端到端业务1的业务类型为L3VPN业务，覆盖域C、域A和域D三个物理域，域C的设备为厂家C的设备，版本为3，域A的设备为厂家A的设备，版本为1，域D的设备为厂家D的设备，版本为3。如前所述，对于组合VPN业务，只需要域C、域A和域D中存在一个域的业务类型为L3VPN业务即可。
输入的业务特征包括业务类型：L3VPN，业务策略：保护策略，网络特征：厂家C，版本3；厂家A，版本1；厂家D，版本3。
第一个第一虚拟业务设计模块包括特征集合{[虚拟域a，厂家A，版本1]，[虚拟域b，厂家B，版本3]，[VLAN对接]，[L3VPN，配置1]，[分解策略1]}，其中，[虚拟域a，厂家A，版本1]，[虚拟域b，厂家B，版本3]为虚拟域的信息，[VLAN对接]为域间连接策略，[L3VPN，配置1]为业务配置、[分解策略1]为分解策略。
第二个第一虚拟业务设计模块包括特征集合{[虚拟域a，厂家A，版本1]，[虚拟域b，厂家D，版本3]，[VLAN对接]，[L3VPN，配置1]，[分解策略2]}，其中，[虚拟域a，厂家A，版本1]，[虚拟域b，厂家B，版本3]为虚拟域的信息，[VLAN对接]为域间连接策略，[L3VPN，，配置1]为业务配置，[分解策略2]为分解策略。
按照第一种匹配方式：
业务类型的优先级最高，网络特征的优先级其次，业务策略的优先级最低。按照优先级从高到低的顺序进行匹配，且只匹配前两个优先级的特征。
第一优先级的特征：业务类型L3VPN，权重100。第二优先级的特征：网络特征，权重100。由于网络包括三个物理域，每个物理域的权重占比为1/3。
首先匹配第一优先级的特征，两个第一虚拟业务设计模板都匹配。然后匹配第二优先级的特征，第一个第一虚拟业务设计模板只有虚拟域a能对应物理域，权重100*1/3，第二个第一虚拟业务设计模板能匹配两个虚拟域，权重100*2/3，第二个第一虚拟业务模板权重为100+100*2/3，第一个第一虚拟业务模板权重为：100+100*1/3，因此第二个第一虚拟业务模板的匹配度更高。
第二种匹配方式：
将网络特征与第一虚拟业务设计模板中的设备特征集合进行匹配，得到第一匹配度；将业务特征与第一虚拟业务设计模板中的业务特征集合进行匹配，得到第二匹配度；根据第一匹配度和第二匹配度，得到第一虚拟业务设计模板的匹配度。
在一种可能的实施方式中，将网络特征与第一虚拟业务设计模板中的设备特征集合进行匹配，得到第一匹配度，包括：确定设备特征集合中与网络特征匹配的设备特征；将确定出的设备特征对应的权重之和，作为第一匹配度。
类似地，将业务特征与第一虚拟业务设计模板中的业务特征集合进行匹配，得到第二匹配度，包括：确定业务特征集合中与业务特征匹配的设备特征；将确定出的业务特征对应的 权重之和，作为第二匹配度。
不同种类的网络特征和业务特征分别预先设置有权重，该权重与对应网络特征和业务特征对业务部署的重要程度正相关，也即是，网络特征和业务特征对业务部署越重要，对应的权值越大。例如，在本申请实施例中，设备厂家、设备版本和业务类型对业务的部署最重要，则设备厂家、设备版本和业务类型对应的权重值相等且最大。
在一种可能的实施方式中，将第一匹配度和第二匹配度之和作为第一虚拟业务设计模板的匹配度。
需要说明的是，在前述两种匹配方式中，进行匹配是指在特征集合中查找相同的特征，如果特征集合中存在相同的特征，则表示存在匹配的特征。
在一种可能的实施方式中，根据匹配度，确定目标虚拟业务设计模板，包括：将匹配度最高的第一虚拟业务设计模板作为目标虚拟业务设计模板。也即是，默认目标虚拟业务设计模板为匹配度最高的第一虚拟业务设计模板。
在另一种可能的实施方式中，根据匹配度，确定目标虚拟业务设计模板，包括：按照匹配度从高到低的顺序对第一虚拟业务设计模板进行排序；展示排列在前的若干个第一虚拟业务设计模板；根据用户指令从若干个第一虚拟业务设计模板中，选择目标虚拟业务设计模板。示例性地，展示的第一虚拟业务设计模板的数量为设定值，例如5个等。
示例性地，在展示出的若干个第一虚拟业务设计模板中，选择实例化后需要作出的修改量最少的业务设计模板对应的第一虚拟业务设计模板作为目标虚拟业务设计模板。
303：根据目标虚拟业务设计模板，生成实例化的业务模板。
实例化的业务模板用于配置网络使得网络承载业务，即将业务部署在该网络中。例如，按照图2所示的流程，完成对网络的配置。
在本申请实施例中，通过输入网络特征实现CFS(customer facing service，面向用户的服务)层端到端业务设计，通过自动匹配目标虚拟业务设计模板，并根据目标虚拟业务设计模板生成实例化的业务模板，实现RFS(resource facing service，面向资源的服务)层的业务设计，无需用户熟悉网络中每个设备的配置方式和约束，降低了业务设计难度和配置难度，并且降低了对工程师的技能要求，减少了获得业务设计模板所需的时间。
此外，虚拟业务设计模板在相似的条件下可以重复使用，降低了业务部署的复制难度。例如，在相同的业务在不同的省份部署时，虽然部分设备存在差异，但是相同的部分仍然可以共用。
示例性地，303包括：
3031：提取网络中物理域的网络特征，包括设备厂家、设备版本等。
3032：在目标虚拟业务设计模板中，确定具有等价物理域的第一虚拟域，等价物理域为与对应的第一虚拟域具有相同的网络特征的物理域。
3033：将目标虚拟业务设计模板中的第一虚拟域的标识替换为等价物理域的标识。使得虚拟域对应的配置被复制到物理域上，得到实例化的业务模板。
可选地，若目标虚拟业务设计模板中还存在没有等价物理域的第二虚拟域，则303还包括：删除第二虚拟域以及第二虚拟域对应的业务特征。
例如，目标虚拟业务设计模板中部署了三个虚拟域，虚拟域A采用厂家A的设备，虚拟域B采用厂家B的设备，虚拟域C采用厂家C的设备，而物理域中，仅包括采用厂家A的 设备的物理域和采用厂家B的设备的物理域，此时，表示目标虚拟业务设计模板中虚拟域C不存在等价的物理域，因此，将目标虚拟业务设计模板中，虚拟域C的相关内容删除。
在一种可能的实施方式中，物理网络中的物理域与目标虚拟业务设计模板中虚拟域的匹配度高，例如，每个物理域在目标虚拟业务设计模板中均存在等价的虚拟域，在这种情况下，直接根据目标业务设计模板转化得到实例化的业务模板，无需执行304。
而在另一种可能的实施方式中，物理网络中的物理域与目标虚拟业务设计模板中的虚拟域的匹配度相对较低，例如，物理网络中的部分物理域在目标虚拟业务设计模板中不存在等价的虚拟域，这种情况下，根据目标虚拟业务设计模板无法直接转化得到与现网匹配的实例化的业务模板，因此，该方法还包括：
304：根据接收到的指令，对实例化的业务模板进行修改。
对实例化的业务模板进行修改，包括以下方式中的至少一种：
新增物理域以及物理域对应的业务特征；
删除物理域以及物理域对应的业务特征；
修改物理域对应的业务特征。
相应地，接收到的指令包括，增加指令、删除指令和修改指令中的至少一种。
这里，新增物理域包括增加物理域标识以及物理域内的设备的特征。删除物理域包括删除物理域标识以及物理域内的设备的特征。业务特征为前述业务特征集合中的特征。
可选地，为了保证业务配置后的可靠性，在利用实例化的业务模板对网络进行配置之前，该方法还包括：
305：对实例化的业务模板进行验证。
示例性地，验证方式包括：
确定业务的边界点，该边界点为租户的接入点，即接入的PE设备；
根据业务的边界点和实例化的业务模板，确定边界点及边界点之间的路径上的配置，其中，边界点之间的路径包括业务经过的网元；
将确定出的配置与基准配置进行比对，得到验证结果。
这里，若确定出的配置与基准配置相同，则验证结果为通过验证；若确定出的配置与基准配置不同(包括部分不同或者全部不同)，则验证结果为未通过验证。
示例性地，业务的边界点是通过输入装置获取的。配置包括配置命令行、配置参数中的至少一种。示例性地，基准配置也是通过输入装置获取的，由技术人员输入。
在一种可能的实施方式中，通过人工查看确定出的配置是否符合要求，得到验证结果。
在实例化的业务模板未通过验证的情况下，技术人员需要对该实例化的业务模板进行进一步修改和验证，直至该实例化的业务模板通过验证。
这里，根据该边界点和实例化的业务模板，确定边界点的配置命令的过程与实际多域控制器和单域控制器确定网络配置的过程相同，但是，得到的配置仅用于对实例化的业务模板进行验证，并不下发到网络。
可选地，在一些实施方式中，不对实例化的业务模板进行验证，直接根据实例化的业务模板进行业务部署。
306：保存通过验证的实例化的业务模板。
例如，将通过验证的实例化的业务模板保存在业务模板库中。利用业务模板库集中保存 实例化的业务模板，以便于对实例化的业务模板进行统一管理，例如，根据实际需要，对业务模板库中的实例化的业务模板进行全生命周期管理，例如导入、导出、发布、取消发布、删除等。
在一种可能的实施方式中，如果实例化的业务模板不是由目标虚拟业务设计模板直接转化得到的，而是经过了修改的业务模板，那么该实例化的业务模板抽象后能够得到新的虚拟业务设计模板。通过对该实例化的业务模板进行抽象化处理，得到对应的第二虚拟业务设计模板，并将第二虚拟业务设计模板作为新的第一虚拟业务设计模板添加到虚拟业务设计模板库中，能够通过自学习的方式增加虚拟业务设计模板库中的虚拟业务设计模板，使得在后续业务部署时，可能匹配到目标虚拟业务设计模板的可能性增大。在这种情况下，该方法还包括：
307：根据实例化的业务模板，生成第二虚拟业务设计模板。
308：将第二虚拟业务设计模板添加到虚拟业务设计模板库中。
示例性地，307通过以下方式实现：
3071：提取实例化的业务模板中的物理域的特征参数，得到各个物理域的特征参数集，该特征参数集包括物理域中的设备厂家、设备版本、物理域的连接关系。
3072：删除特征参数集相同的物理域以及对应的业务配置。
3073：将实例化的业务模板中的各个物理域的标识均替换为一个唯一的虚拟域的标识，以生成第二虚拟业务设计模板。
通过删除特征参数集相同的物理域，以及对应的业务配置，使得到的第二虚拟业务设计模板中重复内容少，以简化第二虚拟业务设计模板。
需要说明的是，如果实例化的业务模板是由目标虚拟业务设计模板直接转化得到的，未经过修改，则无需执行307～308。
在另一种可能的实施方式中，通过人工配置的方式在虚拟业务设计模板库中添加新的虚拟业务设计模板。例如，根据专家经验，生成多个虚拟业务设计模板添加到虚拟业务设计模板库中。
通过自学习和人工配置的方式，均能更新虚拟业务设计模板库中的虚拟业务设计模板，虚拟业务设计模板库中的虚拟业务设计模板越多，后续业务能够匹配到目标需业务设计模板的可能性越大，有利于实例化的业务模板的自动生成。

其中，获取模块410用于执行图3中的301。确定模块420用于执行图3中的302。生成模块430用于执行图3中的303。

此外，虚拟业务设计模板在相似的条件下可以重复使用，降低了业务部署的复制难度。例如，在相同的业务在不同的省份部署时，虽然部分设备存在差异，但是相同的部分仍然可以共用。
