具体实施方式
下面结合附图，对本申请的实施例进行描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。本领域普通技术人员可知，随着技术的发展和新场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请实施例提供本申请实施例提供一种网络管理的方法，可以基于网络的结构化平面对网络中的设备和业务进行自动化的上线管理。本申请实施例还提供了相应的控制设备。以下分别进行详细说明。
本申请实施例中，为了更自动化的管理网络，可以将网络划分成不同的结构化平面(fabric plane)。每个结构化平面基于预规划的网络分层结构可以划分为多个不同的结构化区域(fabric area)。
本申请实施例中，网络管理的任务由控制设备来执行，如图1所示，控制设备会对一定范围内的网络进行管理。例如：一个省份内配置一个控制设备，由该控制设备管理该省份的网络。在做结构化划分时，控制设备获取所管理网络范围内的网络拓扑和预规划的网 络分层结构；所述控制设备为所述网络拓扑确定至少一个结构化平面，其中，不同的结构化平面所关联的网络资源不同，且不同的结构化平面中的转发资源隔离，即使网络中存在没有被划分为结构化平面其他资源，结构化平面也与这部分没被划分为结构化平面资源隔离。针对这种结构化平面的划分方式，各结构化平面之间不存在交叉，可以有效的实现一网多用。
结构化平面是一组网元和链路的集合，以及与该集合绑定的网络配置资源池称为一个结构化平面。一个结构化平面内的网元和链路组成一个连通图。一个网络拓扑可划分为一到多个结构化平面，每个结构化平面可以定义不同的设备范围、接口资源等。
针对每个结构化平面，控制设备根据所述预划分的网络分层结构可以确定至少一种类型的结构化区域(fabric area)。
在一个结构化平面内，提供某种抽象网络能力的一组网元和链路称为一个结构化区域。一个结构化区域的网元和链路是其所属结构化平面内的一个连通子图。结构化区域提供抽象网络功能，该抽象网络功能是结构化区域对其自身转发能力的承诺(assurance)。对于抽象网络功能的使用者，不再需要关注结构化区域内部的连接方式和拓扑结构。
下面结合附图介绍结构化平面(fabric plane)和结构化区域(fabric area)。
控制设备可以获取如图1所示的网元及链路所形成的网络拓扑，该网络拓扑是承载网的一网络拓扑，实际上，本申请实施例中的网络拓扑不限于是承载网的网络拓扑，也可以是其他类型的网络拓扑，例如单层网络拓扑或数据中心网络拓扑。
控制设备可以对图1所示的网络拓扑可以划分为逻辑上相互隔离的多个结构化平面。例如：控制设备可以将图1所述的网络拓扑划分为图2所示的Fabric Plane M和Fabric Plane N两个不同的结构化平面。
在划分结构化平面时，控制设备可以为每个结构化平面灵活定义其包含的网元集合，如图2中的Fabric Plane N包含图1所示的网络拓扑中的全部网元，而Fabric Plane M中不包含网元基站侧网关(cell site gateway，CSG)1和CSG2。
由图2中也可以看出，在划分结构化平面时，相同的网元可以属于不同的Fabric平面，如图2中的网元CSG4，其既属于Fabric Plane M又属于Fabric Plane N。
Fabric Plane M和Fabric Plane N两个结构化平面所关联的网络资源不同，且不同的结构化平面中的转发资源隔离。
连接在同一个Fabric平面的基站间互通使用该Fabric平面内的转发资源，如：子接口集合、网络分片、链路带宽、虚拟专用网络(virtual private network，VPN)实例等。
连接在不同Fabric平面间的两个基站间互通只能通过第三方转发完成，如图2中的基站1和基站3互通需要通过新一代核心网(new generation core,NGC)转发，尽管物理上基站1和基站3都通过CSG3接入网络。
一个Fabric平面可以承载一种或多种VPN业务。在典型的5G承载网场景下，近似的业务尽量部署在一个Fabric平面内。即：在同一个网络内，通过划分不同的Fabric平面，不同服务等级协议(service level agreement，SLA)需求的业务可以使用不同的链路转发资源和不同的网络承载技术。在确定结构化平面之前，控制设备还获取业务的服务等级协议SLA的需求；然后根据所述SLA的需求确定至少一个结构化平面，其中，不同的SLA的需求对应不同的结构化平面。当然，在确定结构化平面时，也不限于SLA的需求这一种方式，也可以根据其他需求或规则来确定结构化平面。
对于每个Fabric平面，都可以进一步再做Fabric区域的规划，一个Fabric平面上可以包括至少一个Fabric区域。如图3所示的结构化区域示意图中所示出的Fabric Area 0、Fabric Area 1和Fabric Area 2是三个不同的Fabric区域。
控制设备可以为每个Fabric区域灵活定义其包含的网元集合，如图3中的Fabric area1中包含汇聚侧网关(aggregate site gateway，ASG)1、ASG2和CSG1、CSG2、CSG3、CSG4、CSG5共7个网元。相同网元可以同时属于多个Fabric区域，如图3中的ASG1，其既属于Fabric area 0又属于Fabric area 1。每个Fabric区域内的网络拓扑都是一个连通子图，每个Fabric区域内的网元都属于相同的内部网关协议(interior gateway protocol，IGP)域。连通子图是相对于Fabric的连通图来说的。连通图是指在一个图G中，若从顶点i到顶点j有路径相连，则称i和j是连通的。连通子图是指如果图G`的所有定点和边都属于图G，则G`是G的子图。IGP域是指位于同一个IGP范围内，同一个IGP域的网元的IGP进程标识可以不同。IGP进程标识可以是IGP进程号，也可以是IGP的其他标识信息。
如图3中，ASG1、ASG2和CSG1、CSG2、CSG3、CSG4、CSG5都在相同的IGP域内且互相连通，可以归集到一个Fabric区域(Fabric area 1)中。同理，如果采用不同的IGP域规划方式，则Fabric区域的范围也不同。如图4中，核心区域边界路由器(core-area border router，C-ABR)1、C-ABR2和ASG8、ASG6、ASG1、ASG2以及CSG1、CSG2、CSG3、CSG4、CSG5处于相同的IGP域内且互相连通，则此时Fabric area 1应包含以上全部这些网元。
Fabric区域对外承诺抽象的网络能力，Fabric区域对内采用相同的承载技术。如一种可能的情况下，Fabric area 1承诺任何从CSG网元接入的业务都有300Mb上行带宽，同时，Fabric area 1内的CSG网元通过配置有带宽保障的分段路由流量工程(segment routing-traffic engineering，SR-TE)隧道达成该承诺。
根据Fabric区域在转发过程中所属的层次和网络拓扑，控制设备可以将Fabric区域分成四种类型：接入(access)类型、汇聚(aggregate)类型、默认(default)类型、数据中心(data centre，DC)类型。每种类型的Fabric area只承诺对应的业务转发能力。
当所述网络拓扑为分层的承载网拓扑时，所述结构化区域的类型包括汇聚类型和接入类型。如图5所示，Fabric Area 0是Aggregate类型的结构化区域，Fabric Area 1和Fabric Area 2是Access类型的结构化区域。其中，Access类型的结构化区域间转发需要经过Aggregate类型的结构化区域，接入Access类型的结构化区域的业务上行转发需要经过Aggregate类型的结构化区域。
以上描述了分层的承载网的区域类型，对于不分层的简单网络，也可以称为单层网络。当所述网络拓扑为单层网络拓扑时，所述结构化区域的类型为默认类型。如图6所示，一个Fabric平面包括一个是默认类型的结构化区域。同样，该默认类型的Fabric区域内的网元和链路拓扑是一个连通图，且所有网元属于一个IGP域。
当所述网络拓扑为数据中心网络拓扑时，所述结构化区域的类型为数据中心类型。对于数据中心网络拓扑，如图7所示，一个Fabric平面包括一个DC类型的Fabric区域。同样，该DC类型的Fabric区域内的网元和链路拓扑是一个连通图，且所有网元属于一个IGP域；特别地，DC类型的Fabric Area的拓扑应同时符合Spine-leaf结构。
需要说明的是，不同类型的Fabric区域可以组合。当网络拓扑为云网共管网络拓扑时，所述结构化区域的类型包括汇聚类型、接入类型和数据中心类型，所述云网共管网络拓扑为所述分层的承载网拓扑和所述数据中心网络拓扑的组合。如图8所示，5G承载网结构是 Access与Aggregate类型的Fabric区域的组合。此时，如果需要与边缘DC(edge DC)共管，则可能出现三种Fabric区域级联的场景。
对于Fabric区域内部的网元，如果不同的网元在转发过程中起到的作用不同，则还需要区分网元角色(network entity role)。网元角色分三种：接入角色(access role)、边界角色(border role)、透传角色(deliver role)。
其中，接入角色：转发过程中，当一个网元接收本Fabric区域外的流量并转发至本Fabric区域中的边缘角色的网元时，其在Fabric区域内为接入角色；典型的，接入类型Fabric区域中，CSG网元一般充当接入角色。
边界角色(Border Role)：转发过程中，当一个网元接收本Fabric区域中的流量并转发至其它Fabric区域中时，其在本Fabric区域内为边界角色；典型的，接入类型Fabric区域中，ASG网元一般充当边界角色。
默认类型的Fabric区域：区域内所有网元的角色都为接入角色。
接入类型的Fabric区域：区域内含有一个到多个接入角色的网元，两个出口节点为边界角色的网元，以及0至多个透传角色的网元；其中边界角色的网元需要标识主备。
汇聚类型的Fabric区域：区域内含有一个到多个接入角色的网元，两个出口节点为边界角色的网元，以及0至多个透传角色的网元；其中边界角色的网元需要标识主备。
DC类型的Fabric区域：区域内含一个到多个接入角色的网元，两个出口节点为边界角色的网元，且需要标识主备。DC类型Fabric区域内，叶子(leaf)网元一般作为接入角色，主干(spine)/网关(gateway，GW)网元一般作为边界角色。
边界角色的网元的转发能力一般强于接入角色的网元，当一个网元属于多个Fabric区域时，其在不同的Fabric区域中的角色可能相同，也可能不同。
以上介绍了结构化区域的四种类型，下面介绍这四种类型的结构化区域的确定过程。
针对承载网的结构化平面，控制设备根据所述预划分的网络分层结构确定至少一种类型的结构化区域可以包括确定汇聚类型的结构化区域和确定接入类型的结构化区域两部分。
其中，控制设备确定汇聚类型的结构化区域的过程可以包括：
所述控制设备获取与第一结构化平面对应的第一意图信息，所述第一意图信息包括所述第一结构化平面中一对核心汇聚网元的信息和所述一核心汇聚网元的第一内部网关协议IGP进程标识，所述第一结构化平面为所述至少一个结构化平面中的任意一个；
所述控制设备根据所述一对核心汇聚网元的信息在所述第一结构化平面中从所述一对核心汇聚网元开始查找与所述第一IGP进程标识在同一个IGP域的网元和链路，以确定出汇聚类型的结构化区域，所述汇聚类型的结构化区域的拓扑图是所述第一结构化平面的连通图中的一个连通子图；
所述控制设备根据所述汇聚类型的结构化区域确定至少一个接入类型的结构化区域。
该种可能的实现方式中，意图信息用于表示网管人员或用户对结构化区域的划分打算。一对核心汇聚网元的信息可以是如图3或图4中的移动汇聚业务网关(mobile aggregate service gateway，MASG)1和MASG2的信息，如：MASG1和MASG2的设备标识，或者互联网协议(internet protocol，IP)地址等信息。MASG1的IGP进程标识与MASG2的IGP进程标识可以相同，也可以不同。但MASG1和MASG2的IGP进程标识都属于同一IGP域。IGP域表示的是一个范围。
根据所述一对核心汇聚网元的信息在所述第一结构化平面中从所述一对核心汇聚网元开始查找与所述第一IGP进程标识在同一个IGP域的网元和链路，以确定出汇聚类型的结构化区域的过程。
以图3为例可以理解为从MASG1和MASG2开始，与MASG1和MASG2的进程标识位于同一个IGP域的中间系统到中间系统(intermediate system to intermediate system，ISIS)process N的网元有C-ABR1、C-ABR2、ASG8、ASG1、ASG2、ASG6、ASG7、ASG3、ASG4和ASG5。
以图4为例可以理解为从MASG1和MASG2开始，与MASG1和MASG2的进程标识位于同一个IGP域的ISIS process N的网元有C-ABR1和C-ABR2。
确定出汇聚类型的结构化区域后，所述控制设备根据所述汇聚类型的结构化区域确定至少一个接入类型的结构化区域可以有两种方案。
其中，方案一：
所述控制设备确定所述汇聚类型的结构化区域中各网元的角色；
所述控制设备在所述第一结构化平面中扣减所述汇聚类型的结构化区域中的链路，以得到至少一个互相不连通的子图；
针对每个互相不连通的子图，从所述汇聚类型的结构化区域中的第一网元开始查找与第二IGP进程标识在同一个IGP域的网元和链路，以得到至少一个接入类型的结构化区域，其中，所述第一网元以及链路，以及与第二IGP进程标识在同一个IGP域的网元和链路构成一个连通子图，不同互相不连通的子图所构成的接入类型的结构化区域的IGP域不同，所述第一网元为连接边数大于2的任意一个接入角色的网元。
该方案一中，以图9为例，网络已归集部分也就是所确定的汇聚类型的结构化区域，该汇聚类型的结构化区域的IGP域的标识信息为ISIS process 100，图9中示出的汇聚类型的结构化区域包括ASG1、ASG2、ASG3、ASG4、ASG5和ASG6这6个网元，这6个网元中ASG1、ASG2、ASG3和ASG4都属于接入角色的网元，ASG5和ASG6是边界角色的网元。在汇聚类型的结构化区域中，只有接入角色的网元才能成为接入类型的结构化区域中的网元。
从图9所示的结构化平面的拓扑中扣减掉汇聚类型的结构化区域的链路，对于未归集部分就会得到两个互相不连通的子图，这两个子图也就是网络未归集部分，也就是要确定的接入类型的结构化区域。这两个子图中的第一个子图因为ASG1和ASG2间的链路被扣减，从而导致这个子图不能连通。第二个子图因为ASG3和ASG4间的链路被扣减，从而导致这个子图不能连通。所以，在确定接入类型的结构化区域时，在汇聚类型的结构化区域的网元中选取边>2的网元，在图9所示的汇聚类型的结构化区域中，忽略链路扣减，ASG1、ASG2、ASG3和ASG4的连接边数都有3个，也就是连接的边数都大于2。所以针对第一个不连通的子图可以从ASG1或ASG2开始查找与ASG1或ASG2的进程标识在同一个IGP域的网元，分别找到了CSG1、CSG2、CSG3、CSG4和CSG5。这样，再加上ASG1和ASG2之间的链路，就确定了一个IGP域的标识是ISIS process 1的接入类型的结构化区域。针对第二个不连通的子图可以从ASG3或ASG4开始查找与ASG3或ASG4的进程标识在同一个IGP域的网元，分别找到了CSG6、CSG7、CSG8、CSG9和CSG10。这样，再加上ASG3和ASG4之间的链路，就确定了一个IGP域的标识是ISIS process 2的接入类型的结构化区域。
通过自动计算，控制设备得到网络归集后的信息如下：
Figure PCTCN2020111700-appb-000001
Figure PCTCN2020111700-appb-000002
方案二：
所述控制设备确定所述汇聚类型的结构化区域中各网元的角色；
所述控制设备获取所述汇聚类型的结构化区域的第二意图信息，所述第二意图信息包括所述汇聚类型的结构化区域中的至少一对接入角色的网元的信息和与每对接入角色的网元对应的IGP进程标识；
所述控制设备根据第一对接入角色的网元的信息在所述第一结构化平面中从所述第一对接入角色的网元开始查找与所述第一对接入角色的网元对应的第三IGP进程标识在同一个IGP域的网元和链路，以确定出与所述第三IGP进程标识对应的接入类型的结构化区域，所述第一对接入角色的网元是所述至少一对接入角色的网元中的任意一对，且每对接入角色的网元所对应的IGP进程标识不相同。
该方案二与方案一的区别是不采用扣减链路的方式，而是根据网管人员或用户指定的意图信息确定接入类型的结构化区域。该意图信息中会包括至少一对接入角色的网元的信息，如图9中，若第二意图信息中包括了ASG1和ASG2的信息，以及ASG1和ASG2的IGP进程标识，则控制设备可以从ASG1和ASG2开始，查找与ASG1和ASG2的IGP进程标识在同一个IGP域的网元，通过查找可以确定CSG1、CSG2、CSG3、CSG4和CSG5与ASG1和ASG2在同一个IGP域ISIS process 1，则确定了一个接入类型的结构化区域。另外，若该第二意图信息中包括了ASG3和ASG4的信息，以及ASG3和ASG4的IGP进程标识，则控制设备可以从ASG3和ASG4开始，查找与ASG3和ASG4的IGP进程标识在同一个IGP域的网元，通过查找可以确定CSG6、CSG7、CSG8、CSG9和CSG10与ASG3和ASG4在同一个IGP域ISIS process 2，则确定了另一个接入类型的结构化区域。
该第二种方案中，也可以是用户指定一对ASG设备和一对下行接口时，还可以指定这个接入类型的Fabric区域的名称和IGP process id。
如图10所示，第二意图信息中包括了要创建的接入类型的结构化区域的名称为：Fabric_acc3。指定的一对设备为ASG5和ASG6，并指定了ASG6为主边界设备，ASG5为从边界设备。ASG5和ASG6的下行接口标识都为port 1/0/1。指定的IGP process id为ISIS 3。
对于默认类型的结构化区域的确定过程可以是：
所述控制设备获取第二结构化平面对应的第三意图信息，所述第三意图信息包括一对设备的信息和所述一对设备的第四IGP进程标识，所述第二结构化平面为所述至少一个结构化平面中的任意一个；
所述控制设备根据所述一对设备的信息在所述第二结构化平面中从所述一对设备开始查找与所述第四IGP进程标识在同一个IGP域的设备和链路，以确定出默认类型的结构化区域，所述默认类型的结构化区域的稀疏连通图为所述所管理网络范围内的网络拓扑的一个子集。

本申请实施例提供的接入设备自动化下线的方案，在接入设备下线后，可以针对发生配置变化的网元自动更新这些变更网元的变更配置信息，从而实现配置信息的自动化更新。另外还会自动更新连通子图，不需要人工参与，提高了设备下线时网络管理的效率。
2、接入承载网的第一基站自动化上线过程和基于该第一基站的VPN业务的自动化上线过程。
下面参阅图13介绍第一基站上线的过程：
301、第一基站插入第三接入设备的接口后，第三接入设备向控制设备发送第一基站上线的信息。对应地，控制设备获取到第一基站上线的信息。
所述第一基站上线信息中包括所述第一基站在所述接入类型的结构化区域上所接入的第三接入设备的接口信息和所述第一基站的电子序列号(electronic serial number，ESN)。其中，第三接入设备的接口信息可以是第三接入设备的接口标识。
302、控制设备根据所述第三接入设备的接口信息和所述第一基站的ESN为所述第一基站分配第一IP地址和第一掩码，为所述接口信息所指示的接口分配第二IP地址和第二掩码。
所述第一IP地址和所述第二IP地址属于同一个网段。该过程可以是所述控制设备根据所述第三接入设备的接口信息和所述第一基站的ESN确定所述第三接入设备所属的结构化平面所关联的资源池，所述资源池包括所述第三接入设备所属的结构化平面对应设备可分配的IP地址和掩码；控制设备根据所述资源池为所述第一基站分配第一IP地址和第一掩码，为所述接口信息所指示的接口分配第二IP地址和第二掩码。
303、控制设备向动态主机配置协议(dynamic host configuration protocol，DHCP)服务器发送所述第一基站的ESN、所述第一IP地址和所述第一掩码。
304、DHCP服务器通过第三接入设备向第一基站发送所述第一IP地址和所述第一掩码。
305、第一基站使用所述第一IP地址和所述第一掩码进行自动上线配置。

参阅图14，基于第一基站进行业务上线的过程可以包括：
401、控制设备根据所述第一基站的ESN获取基于所述承载网的所述第一结构化平面的第一可用流量模型。
所述第一可用流量模型包括基站与互联网通信的流量子模型、网管流量子模型和基站与基站通信的流量子模型；
该种可能的实现方式中，第一基站与互联网通信的流量子模型可以称为N2/N3业务流量模型，网管流量模型可以称为(orchestrator mangment，OM)管理流量子模型，第一基站与其他基站通信的流量模型可以称为Xn业务流量子模型。
N2/N3业务流量子模型可以在控制设备上设计如图14A所示的连接关系：
图14A中，含有两种接入点类型，第一基站和NGC；NGC侧接入点类型为Hub，第一基站侧接入点类型为Spoke；接入点最终会被实例化为一个或一对接入设备。图14A中，含有两种Fabric区域类型，Access型和Aggregate型；第一基站接入侧spoke点在Access类型的 Fabric区域中；NGC接入侧hub点在Aggregate类型的Fabric区域中，两个Fabric区域中间的Hub作为VPN业务跨层的中继节点。Fabric区域类型最终会被指定到具体的一个Access类型的Fabric区域和一个Aggregate类型的Fabric区域中去。
OM管理流量模型可以在控制设备上设计如图14B所示的连接关系，Xn业务流量模型可以在控制设备上设计如图14C所示的连接关系。图14B和图14C中所表达的连接关系与图14A相似，可以参阅上述图14A对应的相应描述进行理解。
402、控制设备根据所述第一可用流量模型确定所述第一结构化平面中不同网元的功能需求，并确定所述第一结构化平面中满足通过所述第一基站布放的虚拟专用网络VPN业务的至少一条业务路径。
其中，不同的功能需求对应不同的流量子模型，每种流量子模型对应一套配置模板；
在网络拓扑中，每个网元的功能需求是不同的，例如：图14D中Spoke1既承担着与互联网通信的任务，又承担与其他第一基站通信的任务，而Spoke2只承担与所以该Spoke1通信的任务。这种情况下，Spoke1既要配置第一基站与互联网通信的流量模型的配置模板，又要配置第一基站与第一基站通信的流量模型的配置模板。而Spoke2只需要配置第一基站与第一基站通信的流量模型的配置模板即可。
在网络中，从A点到达B点，可通行的路径可以有多条，例如：如图15所示，从海淀环保园到西直门的路径可以有多条。
403、控制设备从所述至少一条业务路径中确定满足所述VPN业务的服务等级协议SLA要求的最优路径。
路径有多条时，每条路径的SLA可能都不相同，例如：有的路径带宽大，时延小等，而有的路径带宽小，时延大。这样就可以根据各条路径的SLA选择一条最优路径。例如图15中，从海淀环保园到西直门的路径可以有路径1：海淀环保园-PE1-PE2-PE4-西直门，还可以有路径2：海淀环保园-PE1-PE3-PE5-西直门。路径1的SLA高于路径2，那么可以选路径1作为最优路径。
404、控制设备根据所述不同网元的功能需求为所述最优路径上的关键网元生成网元配置信息，所述网元配置信息包括所述关键网元所属流量子模型对应的配置模板。
关键网元可以是最优路径上的所有网元，也可以是部分网元。
在网络拓扑中，每个网元的功能需求是不同的，Spoke1既承担着与互联网通信的任务，又承担与其他第一基站通信的任务，而Spoke2只承担与所以该Spoke1通信的任务。这种情况下，Spoke1既要配置第一基站与互联网通信的流量模型的配置模板，又要配置第一基站与第一基站通信的流量模型的配置模板。而Spoke2只需要配置第一基站与第一基站通信的流量模型的配置模板即可。
405、控制设备向所述关键网元发送所述网元配置信息。
所述网元配置信息用于所述关键网元进行自动化配置。
相比对现有技术中根据工单中的业务诉求和网络参数，通过运维人员把它转化成业务配置脚本并下发配置的业务上线方案，本申请实施例提供的业务自动化上线的管理方案，速度快，而且准确度高。
3、归属于默认类型的结构化区域中的接入设备自动化上线和自动化下线过程。
对于中小型网络，由于设备数量少，接入需求相对简单，所以在网络建设时更倾向于 简化多层网络设计，设备间的通道一般可抽象为全连接(fullmesh)结构，连接数正比于设备数量的平方，设备数量的增加将导致设备间的通道管理困难。本申请实施例中将这种单层的简单网络规划为default类型的Fabric区域，可以有效的管理区域内的连接，实现网络变更的自动化管理。下面参阅图16介绍单层的简单网络的设备上线的过程。

第四接入设备所属的结构化平面会对应一个资源池，控制设备可以根据该资源池中的资源为第四接入设备分配上述配置信息。
504、控制设备向所述第四接入设备发送所述配置信息。
所述配置信息用于所述第四接入设备在所述默认类型的结构化区域中正常工作。
如图17所示，若该结构化平面中新增加的设备为路由器router7，则控制设备为router7发送配置信息，用于router7在所述默认类型的结构化区域中正常工作。

另外，当所述默认类型的结构化区域中下线了第五接入设备时，所述控制设备获取所述第五接入设备的链路关系；
所述控制设备在所述默认类型的结构化区域对应的第一稀疏连通图中删除所述第五接入设备和其对应的链路关系，并重新建立所述第一稀疏连通图中剩余设备的链路关系，以得到第二稀疏连通图。
针对简单的单层网络，可以通过上述默认类型的结构化区域的划分来自动化管理设备上线和下线，从而提高了网络管理的效率。
4、接入DC网络的VN自动化上线过程、基于VM的业务自动化上线和VM迁移的过程。

所述控制设备根据所述资源池为所述第一VM分配第三IP地址。
603、控制设备根据所述第一接口的信息和所述第一VM所在的服务器的ESN、第一VM的标识，第一VM的MAC地址为所述第一VM分配第三IP地址。

以图19所示出的为例，图19是DC网络的一结构示意图。若该图19中虚拟机网络功能(virtual network function，VNF)1中的VM1表示第一虚拟机，则该VM1通过TOR1接入DC类型的结构化区域，TOR1可以通过图19中的spine节点和数据中心网关向控制器上报该VM1上线的信息，然后控制器会通过上述控制设备所执行的过程，为该VM1分配第三IP地址，该第三IP地址用于VM1进行自动上线配置。
在第一VM上线后，就可以基于该第一VM实现VPN业务的自动化上线过程。该过程可以参阅图20进行理解。

所述第二可用流量模型包括所述VM与互联网通信的流量子模型和VM与VM通信的流量子模型。
702、控制设备根据所述第二可用流量模型确定所述第一结构化平面中不同网元的功能需求，并确定所述第一结构化平面中通过所述第一VM布放的VPN业务的M条业务路径。
其中，不同的功能需求对应不同的流量子模型，每种流量子模型对应一套配置模板，所述M为大于0的整数。

因为VM是一块虚拟化的资源，VM可能会发生迁移，在基于第一VM布放业务后，随着第一VM迁移，业务也会随之迁移。
虚拟机迁移过程中可以包括：
