(2)CPE之间根据SD-WAN控制器下发的密钥信息编号在各个WAN口上建立IPSEC会话。
(3)SD-WAN控制器定义业务流(可以是SD-WAN报文)的等级，并对CPE设备的之间的WAN接口之间的不同隧道设置不同的安全等级。
(4)部署DetNet成功后，DetNet控制器主动连接SD-WAN控制器，可以通过BGP-链路状态(Link State，LS)的方式，上报具有DetNet的传输能力，并上报DetNet边缘网络的拓扑信息到SD-WAN控制器。
(5)SD-WAN控制器根据步骤(4)DetNet控制器上报的DetNet的网络边缘拓扑信息，为第一CPE选择最近的DetNet中的第一PE设备和第二CPE选择最近的DetNet的第二PE设备，并将对应的最近的第一网关上加载DetNet报文 的封装能力。
(6)SD-WAN控制器下发业务请求给DetNet控制器。该业务请求中携带第一PE设备、第二PE设备的信息和业务要求信息。根据草案draft-ietf-detnet-flow-information-model中描述，需要下发的业务要求信息可以包括，流量特性信息循环间隔、每个循环间隔的最大报文数、最大报文长度、最小带宽、最大时延、最大可容忍时延、最大丢包率，最大可容忍丢包率和最大容忍乱序，分配资源计算路径。SD-WAN控制器可通过YANG模型将业务请求配置到DetNet控制器。
DetNet控制器收到业务请求后，会根据业务要求信息、第一PE设备和第二PE设备的信息计算出一条DetNet的确定性路径。DetNet控制器将计算出的flow-ID(确定性路径的标识)上报给SD-WAN控制器。
(7)SD-WAN控制器在收到步骤(6)中DetNet控制器上报的信息后，计算出离DetNet中第二PE设备最近的第二GW，并在对应的第二GW上安装DetNet报文处理能力。
(8)SD-WAN控制器下发第一引流规则到第一GW上，将报文流量引流到第一PE设备上。可以通过netconf的YANG模型下发，也可以通过BGP下发。SD-WAN报文可以是纯IP报文，匹配规则信息包括源IP、目的IP、源端口、目的端口、协议类型、DSCP值，IPSECSPI。SD-WAN控制器并设置对应的行为，即在报文匹配后将报文引流到对应的DetNet中，设置之前由DetNet控制器上报到SD-WAN控制器的对应的DetNet的flow-ID。
(9)SD-WAN控制器下发第二引流规则到第二GW上，将对应的DetNet报文封装头剥掉，替换成纯SD-WAN报文。
(10)当真正有确定性业务的报文要从第一CPE到第一GW时，第一GW就会将此报文封装为DetNet报文，并且转发给DetNet域中的第一PE设备处理，第一PE设备根据DetNet内的确定性路径转发到对应的DetNet内的输出节点第二PE设备，然后由第二PE设备将DetNet报文转发给第二GW，在第二GW处DetNet报文将解外层隧道头，并还原成原来的SD-WAN报文，最终转发到对应的第二CPE上。
本申请实施例提供的方法，可以在SD-WAN的网络提供DetNet服务，该方法同样适用于在SD-WAN的网络中将当前的报文流动态迁移到其他网络，运营商不再感知到客户端的业务，方便网络的灵活迁移和部署。
