步骤102b：根据业务流的目的地址，获取业务流的业务标识；
步骤103b：将业务流的业务标识封装到报文中，向交换机发送报文，使交换机根据业务流的业务标识获取报文的处理策略，并根据处理策略确定是否发送报文，如果发送报文，根据处理策略将报文发送给第二虚拟机。
在本发明中，接收第一虚拟机所在的第一主机发送的报文，该报文携带业务流的业务标识，业务流的业务标识为第一主机根据业务流的目的地址设置并封装到报文中的；根据业务流的业务标识，获取报文的处理策略；根据处理策略，确定是否发送报文；如果发送报文，则根据处理策略，将报文发送给第二
虚拟机。由于报文中携带业务流的业务标识，从而能够根据业务流的业务标识对报文进行策略控制。
实施例2
本发明实施例提供了一种发送报文的方法，参见图2，其中，该方法包括：
步骤201：第一主机接收第一虚拟机发送的业务流，该业务流携带业务流的目的地址；
第一虚拟机部署在第一主机上，第二虚拟机部署在第二主机上；当第一虚拟机向第二虚拟机发送业务流时，第一虚拟机首先向第一虚拟机所在的第一主机发送业务流，该业务流至少携带业务流的目的地址，还可以携带第一虚拟机的标识和第二虚拟机的标识；第一主机接收第一虚拟机发送的业务流，执行步骤202。
目的地址可以为目的IP(Internet Protocol， 网络之间互连的协议)地址、目的端口或者目的MAC(Media Access Control，介质访问控制)地址等。第一虚拟机的标识可以为第一虚拟机的IP地址、第一虚拟机的名称或者第一虚拟机的编号等；同样，第二虚拟机的标识可以为第二虚拟机的IP地址、第二虚拟机的名称或者第二虚拟机的编号等。
例如，以目的地址为目的端口80，第一虚拟机的标识为192.231.31.252，第二虚拟机的标识为192.231.31.251为例进行说明，第一虚拟机向第一主机发送业务流，该业务流携带目的端口80，第一虚拟机的标识192.231.31.252和第二虚拟机的标识192.231.31.251。第一主机接收第一虚拟机发送的该业务流。
步骤202：第一主机根据业务流的目的地址，获取业务流的业务标识；
在本步骤之前，用户向第一控制器输入目的地址和业务标识；第一控制器接收用户输入的目的地址和业务标识，将用户输入的目的地址和业务标识存储在目的地址和业务标识的对应关系中。
第一控制器向第一主机发送目的地址和业务标识的对应关系，第一主机接收第一控制器发送的目的地址和业务标识的对应关系，并存储目的地址和业务标识的对应关系。
相应的，步骤202可以为：第一主机根据业务流的目的地址，从目的地址和业务标识的对应关系中获取业务流的业务标识。
第一控制器可以为SDN(Software Defined Network，软件定义网络)控制器或者VxLAN(Virtual eXtension xLAN，虚拟扩展VLAN协议)控制器等。
例如，用户向第一控制器输入目的地址80和业务标识1025，目的地址443和业务标识2049，目的地址5000和业务标识4097以及目的地址5001和业务标识4098；第一控制器接收用户输入的目的地址80和业务标识1025，目的地址443和业务标识2049，目的地址5000和业务标识4097以及目的地址5001和业务标识4098，将用户输入的目的地址和业务标识存储在如下表1中：
表1
| 目的地址 | 业务标识 |
| 80 | 1025 |
| 443 | 2049 |
| 5000 | 4097 |
| 5001 | 4098 |
例如，第一主机根据业务流的目的地址80，从表1存储的目的地址和业务标识的对应关系中获取业务流的业务标识为1025。
其中，业务标识字段范围是65535，一台主机上可以部署50台虚拟机。对于每个虚拟机对应的业务标识字段范围为1-1024，也即每台虚拟机最多可以定义1024个业务标识，用于对不同的业务进行策略控制。
步骤203：第一主机将业务流的业务标识封装到报文中，向交换机发送报文；
其中，报文包括内层报文和外层报文，本步骤中第一主机将业务流的业务标识封装到外层报文中。
其中，外层报文中还包括源MAC、目的MAC、VLAN、源IP、目的IP、VxLAN端口、VxLAN头等，第一主机获取该业务流的源MAC、目的MAC、VLAN、源IP、目的IP、VxLAN端口、VxLAN头，将该业务流的源MAC、目的MAC、VLAN、源IP、目的IP、VxLAN端口、VxLAN头和报文的业务标识同时封装到外层报文中。
其中，内层报文包括源MAC、目的MAC和业务流，第一主机获取该业务流的源MAC、目的MAC和业务流，将该业务流的源MAC、目的MAC和业务流封装到内层报文中。
步骤204：交换机接收第一主机发送的报文，该报文携带该业务流的业务标识；
交换机接收第一主机发送的报文，解析该报文的外层报文得到该业务流的业务标识，执行步骤205。
需要说明的是，交换机只能解析报文的外层报文，并不能解析报文的内层报文。
步骤205：交换机根据业务流的业务标识，获取该报文的处理策略；
在本步骤之前，用户向第二控制器输入业务标识和处理策略；第二控制器接收用户输入的业务标识和处理策略，将用户输入的业务标识和处理策略存储在业务标识和处理策略的对应关系中。
第二控制器向交换机发送业务标识和处理策略的对应关系，交换机接收第二控制器发送的业务标识和处理策略的对应关系，并存储业务标识和处理策略的对应关系。
相应的，步骤205可以为：交换机根据业务流的业务标识，从业务标识和处理策略的对应关系中获取该报文的处理策略。
处理策略可以为任一对报文进行处理的策略，包括用于丢弃报文的处理策略和用于对报文执行除丢弃以外的其他操作的处理策略；例如处理策略可以为丢弃策略、转发策略、重定向策略或者基于带宽的路径控制策略等。
第二控制器可以为SDN控制器或者OF(openflow，开放流表协议)控制器。
例如，用户向第二控制器输入业务标识1025和处理策略：正常转发，业务标识2049和处理策略：丢弃，业务标识4097和处理策略：重定向到低权重路径，业务标识4098和处理策略：设置转发路径的带宽大小为100M等；第二控制器接收用户输入的业务标识1025和处理策略：正常转发，业务标识2049和处理策略：丢弃，业务标识4097和处理策略：重定向到低权重路径，业务标识4098和处理策略：设置转发路径的带宽大小为100M等，将用户输入的业务标识和处理策略存储在如下表2中：
表2
| 业务标识 | 处理策略 |
| 1025 | 正常转发 |
| 2049 | 丢弃 |
| 4097 | 重定向到低权重路径 |
| 4098 | 设置转发路径的带宽大小为100M |
例如，交换机根据业务标识1025，从表2存储的业务标识和处理策略的对
应关系中获取报文的转发策略为正常转发。
步骤206：交换机根据该报文的处理策略，确定是否发送该报文，如果发送该报文，执行步骤207；如果不发送该报文，执行步骤212；
具体地，如果该报文的处理策略用于丢弃该报文，则确定不发送该报文；如果该报文的处理策略用于对报文执行除丢弃以外的其他操作，则确定发送该报文。
例如，该报文的处理策略可以为丢弃策略、转发策略、重定向策略或者基于带宽的路径控制策略等。则如果处理策略为丢弃策略，则确定不发送该报文；如果处理策略为转发策略、重定向策略或者基于带宽的路径控制策略，则确定发送该报文。
步骤207：如果发送该报文，则交换机根据第一虚拟机的标识和第二虚拟机的标识，确定用于发送该报文的至少一条转发路径；
在本步骤之前，第二控制器获取交换机所在的物理网络的拓扑结构，向交换机发送物理网络的拓扑结构，交换机接收第二控制器发送的物理网络的拓扑结构，并存储物理网络的拓扑结构。
相应的，步骤207可以为：如果发送该报文，则交换机根据第一虚拟机的标识、第二虚拟机的标识以及物理网络的拓扑结构，确定用于发送该报文的至少一条转发路径。
根据第一虚拟机的标识、第二虚拟机的标识以及物理网络的拓扑结构，确定用于发送该报文的至少一条转发路径为现有技术，在此不再详细说明。
进一步地，交换机根据至少一条转发路径中的每条转发路径的路径标识，获取每条转发路径的路径权重。
在本步骤之前，用户向第二控制器输入权重规则，该权重规则可以为根据转发路径包括的转发实体的数量进行设置。第二控制器接收用户输入的权重规则，并根据权重规则生成物理网络中的每条转发路径的路径权重，将每条转发路径的路径标识和每条转发路径对应的路径权重存储在路径标识和路径权重的对应关系中。
第二控制器向交换机发送路径标识和路径权重的对应关系；交换机接收第二控制器发送的路径标识和路径权重的对应关系，并存储路径标识和路径权重的对应关系。
相应的，根据至少一条转发路径中的每条转发路径的路径标识，获取每条
转发路径的路径权重，可以为：
根据至少一条转发路径中的每条转发路径的路径标识，从路径标识和路径权重的对应关系中获取每条转发路径的路径权重。
例如，用户向第二控制器输入的权重规则为：包括转发实体在1-5之间的转发路径的路径权重为500，包括转发实体在6-10之间的转发路径的路径权重为400，包括转发实体在11-15之间的转发路径的路径权重为300，包括转发实体在16-20之间的转发路径的路径权重为200，包括转发实体大于的转发路径的路径权重为100。第二控制器接收用户输入的权重规则，根据权重规则生成路径1对应的路径权重为100，路径2对应的路径权重为500，路径3对应的路径权重为200，路径4对应的路径权重为300等；第二控制器将路径1、路径2、路径3和路径4及其对应的路径权重存储在如下表3中：
表3
| 路径标识 | 路径权重 |
| 1 | 100 |
| 2 | 500 |
| 3 | 200 |
| 4 | 300 |
例如，交换机根据第一虚拟机的标识和第二虚拟机的标识，确定出用于发送该报文的3条路径分别为路径1，路径2和路径3；并且，根据路径1、路径2和路径3的路径标识，从表3中获取路径1、路径2和路径3对应的路径权重分别为100、500和200。
步骤208：交换机根据该报文的处理策略，从至少一条转发路径中选择转发路径；
如果该报文的处理策略为转发策略或者基于带宽的路径控制策略，则从至少一条转发路径中随机选择一条转发路径。
如果该报文的处理策略为重定向，则获取该报文的处理策略中包括的重定向条件，从至少一条转发路径中选择一个满足重定向条件的一条转发路径。例如，重定向的条件为选择最高权重的转发路径，则根据每条转发路径的路径权重，从至少一条转发路径中选择一个路径权重最高的转发路径；如果重定向的条件为选择最低权重的转发路径，则根据每条转发路径的路径权重，从至少一条转发路径中选择一个路径权重最低的转发路径。
例如，报文的处理策略为重定向到最低权重的转发路径上，则从路径1、路径2和路径3中选择一个路径权重最低的转发路径为路径1。
步骤209：交换机根据该报文的处理策略，获取选择的转发路径的带宽；
每种处理策略对应一个转发路径的带宽大小，根据该报文的处理策略，获取选择的转发路径的带宽大小。
其中，转发策略和重定向策略对应的带宽大小为默认的带宽大小；基于带宽的路径控制策略对应的带宽大小为处理策略中包括的带宽大小。
例如，默认的带宽大小为50M，则转发策略和重定向策略对应的带宽大小为50M，；基于带宽的路径控制策略中包括转发路径对应的带宽为100M。
步骤210：交换机根据获取的带宽，设置选择的转发路径的带宽大小；
具体地，交换机将选择的转发路径的带宽大小设置为获取的带宽。
例如，选择的转发路径为路径1，获取的带宽为100M，则将路径1的带宽大小设置为100M。
步骤211：交换机根据设置后的转发路径，将报文发送给第二虚拟机。
具体地，交换机根据设置后的转发路径，将报文转发给第二虚拟机所在的第二主机，第二主机接收交换机发送的该报文，将该报文进行解封装，得到第二虚拟机的标识和业务流，根据第二虚拟机的标识，将该业务流发送给第二虚拟机。
步骤212：如果不发送该报文，则交换机将该报文丢弃。
如果处理策略为丢弃策略，则交换机不发送给报文，直接将该报文丢弃。
在本发明中，接收第一虚拟机所在的第一主机发送的报文，该报文携带业务流的业务标识，业务流的业务标识为第一主机根据业务流的目的地址设置并封装到报文中的；根据业务流的业务标识，获取报文的处理策略；根据处理策略，确定是否发送报文；如果发送报文，则根据处理策略，将报文发送给第二虚拟机。由于报文中携带业务流的业务标识，从而能够根据业务流的业务标识对报文进行策略控制。
