为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍。

具体实施方式
请参见图1，图1是本申请实施例涉及的一种通信***的架构示意图，该通信***可以是云网络***。该通信***包括控制设备，交换机(或称物理交换机)集群和多台物理机。
其中，每台物理机上均可以配置或部署一台或多台虚拟机，具体配置数量由控制设备决定。每一物理机均有一物理网口，每一虚拟机可以对应一个虚拟网卡，同一物理机上的多个虚拟机对应到同一个物理网口上，每个虚拟网卡均可以具备独立的IP地址，具体可以由控制设备配置并发送给各个物理机。同一物理机上的多个虚拟机的IP地址可以位于同一IP网段下，进行通信的两台物理机的IP地址可以位于同一IP网段下。
其中，交换机用于对任意两台物理机之间传输的报文或数据进行转发。例如，每一物理机均有一物理网口，当交换机接收到某一物理网口发送的报文后，识别该报文的目的IP地址或者目的MAC地址，进而将该报文发送给该目的IP地址或者目的MAC地址对应的另一物理网口，从而实现两台物理机的报文 通信。交换机集群中可以包括一台或多台交换机，若交换机集群中包括多台交换机，则其中可以有主交换机和备交换机，当主交换机发生故障，备交换机可以接替主交换机继续进行数据包转发操作。
控制设备分别与每台物理机以及交换机集群中的主交换机进行连接。控制设备可以分配网络中的各个物理机的IP网段以及各个物理机上的全部虚拟机的IP地址，需要进行通信的两台物理机的IP网段需要处于同一IP网段下，只要IP在同一个网段，就可以实现二层通信。控制设备分配了IP地址后，可以将IP地址映射表发送给交换机以及各台物理机。各台物理机可以通过IP地址映射表获知通信对端的物理机上各个虚拟机的IP地址。交换机可以通过IP地址映射表实现物理机之间的报文转发。
本申请实施例中提及的控制设备可以是软件定义网络(Software Defined Network，SDN)控制设备或者其他控制设备。第一物理机和第二物理机可以是电脑、服务器或其他实体设备。
本申请实施例为了便于描述，以多台物理机中的第一物理机和第二物理机，多台交换机中的主交换机为例来进行说明。其中控制设备与主交换机、第一物理机和第二物理机通过云网络相互通信。在该通信***中，第一物理机的第一虚拟机产生心跳报文后，心跳报文发送给主交换机，主交换机接收到第一物理机上的第一虚拟机发往第二物理机上的第二虚拟机的心跳报文后向控制设备发送第一指示信息，然后通过IP地址映射表识别出对端物理机，即第二物理机，进而将第一物理机发送的心跳报文发送给第二物理机。第二物理机上的第二虚拟机收到第一物理机上的第一虚拟机发送的心跳报文后，基于第一心跳报文生成第二心跳报文，将第二心跳报文发送给主交换机，主交换机接收到第二心跳报文后，向控制设备发送第二指示信息。控制设备若在接收到第一指示信息的预设时间段内没有接收到第二指示信息，则判定第二虚拟机发生故障。若第二物理机上的全部虚拟机均发生故障，则判定第二物理机发送故障。因此，本申请可以精准识别出故障源是虚拟机还是物理机。

通信接口202用于网络设备200与其他网络设备进行通信，例如物理机进行通信。通信接口202可以是收发器、收发电路等，其中，通信接口是统称，可以包括一个或多个接口，例如控制设备与交换机之间的接口。通信接口202可以包括有线接口和无线接口，例如标准接口、以太网、多机同步接口。

结合图1所示的通信***架构示意图，参见图3，图3提供了一种故障检测方法的流程示意图。其中，该故障检测方法可以包括：
S301，交换机接收第一虚拟机发往第二虚拟机的第一心跳报文。
本申请中，第一虚拟机为第一物理机上的虚拟机，第一物理机上配置有一个或多个虚拟机。第二虚拟机为第二物理机上的虚拟机，第二物理机上配置有一个或多个虚拟机。第一物理机上的每个虚拟机均与第二物理机上的某一虚拟机建立心跳链路，用于传输心跳报文。下述实施例以第一虚拟机与第二虚拟机之间传输心跳报文为例，以辅助控制设备进行全局的故障检测。
S302，交换机向控制设备发送第一指示信息，控制设备接收交换机发送的第一指示信息，该第一指示信息用于指示交换机接收到第一虚拟机发往第二虚拟机的第一心跳报文。
交换机接收到心跳报文后，需要向控制设备上报心跳传输事件，以辅助控制设备检测网络中的物理机或虚拟机是否发生故障。交换机可以识别出第一心跳报文的源IP地址和目的IP地址，源IP地址即第一虚拟机的IP地址，目的IP地址及第二虚拟机的IP地址。第一指示信息中可以包括该第一心跳报文的源IP地址以及目的IP地址。
S303，若交换机在发送第一指示信息之后的预设时间段内接收到第二虚拟机发往第一虚拟机的第二心跳报文，则交换机向控制设备发送第二指示信息，第二指示信息用于指示交换机接收到第二虚拟机发往第一虚拟机的第二心跳报文，第二心跳报文是第二虚拟机根据第一心跳报文生成的。
若交换机在发送第一指示信息之后的预设时间段内未接收到第二虚拟机 发往第一虚拟机的第二心跳报文，则交换机不会向控制设备发送第二指示信息。
示例性的，交换机在将第一心跳报文发送给第二虚拟机所属的第二物理机后，可以启动计时器，若在计时器结束之前接收到第二虚拟机发往第一虚拟机的第二心跳报文，则交换机需要向控制设备上报第二指示信息，指示第二虚拟机响应了心跳报文。若在计时器结束后仍未接收到第二虚拟机发往第一虚拟机的第二心跳报文，则交换机不会向控制设备上报第二指示信息，隐式指示第二虚拟机未响应心跳报文。或者，若在计时器结束后仍未接收到第二虚拟机发往第一虚拟机的第二心跳报文，则交换机向控制设备上报第三指示信息，指示第二虚拟机未响应心跳报文。
S304，若控制设备在接收到第一指示信息后的预设时间段内没有接收到交换机发送的第二指示信息，则判定第二虚拟机发生故障。
控制设备在接收到交换机发送的第一指示信息后，可以启动计时器，若在计时器结束之前接收到交换机发送的第二指示信息，则判定第二虚拟机没有发生故障。若在计时器结束后仍未接收到交换机发送的第二指示信息，则判定第二虚拟机发生故障。或者，若在计时器结束后接收到交换机发送的第三指示信息，指示第二虚拟机未响应心跳报文，则判定第二虚拟机发生故障。
上述计时器均可以是倒计时模式。倒计时的时长可以由控制设备配置。
实施本申请实施例，控制设备可以根据虚拟机之间的心跳报文从发送到响应之间的时间间隔来判断虚拟机是否存在故障，例如，若第一虚拟机向第二虚拟机发送了第一心跳报文后的预设时间段内第二虚拟机未响应心跳报文，则可以识别出第二虚拟机发生了故障，因此，可以精准检测出通信链路的故障源是否是虚拟机。
可选的，除了可以识别出故障源是否是虚拟机以外，控制设备还可以进一步识别出故障源是否是物理机。控制设备可以采用上述方式检测各个虚拟机是否发生故障，若检测到某一物理机上的全部虚拟机均发生故障，则判定是物理机出现故障。物理机出现故障即会导致该物理机上的全部虚拟机均无法正常响应心跳报文。
实施本申请实施例，控制设备根据虚拟机之间的心跳报文从发送到响应之间的时间间隔判断出某一物理机上的全部虚拟机均发生故障后，可以进一步判断出通信链路的故障源是该物理机，因此可以快速有效找到导致虚拟机之间通信链路发生故障的故障源，节省定位故障的时间。
可选的，控制设备检测出故障虚拟机或故障物理机之后，可以将发生故障的虚拟机的标识和/或物理机的标识进行汇总并输出给管理人员(或运维人员)，由管理人员对发生故障的虚拟机或物理机进行进一步检测故障原因并维修，比如如果是物理机操作***问题造成的物理机故障，则管理人员解决***问题，如果是物理机的硬件电路问题造成的物理机故障，则管理人员解决电路问题，以恢复该故障物理机的正常运行。又例如，如果是虚拟机配置问题造成的虚拟机故障，则管理人员解决该配置问题，以恢复该故障虚拟机的正常运行。
可选的，各个物理机的网段以及各个物理机上的虚拟机的IP地址可以由控制设备配置，控制设备为第一物理机上的全部虚拟机和第二物理机上的全部虚拟机分别分配IP地址，将第一物理机上的全部虚拟机的IP地址和第二物理机上的全部虚拟机的IP地址发送给交换机，第二虚拟机的IP地址用于交换机将第一心跳报文发送给第二物理机。控制设备还将第一物理机上的全部虚拟机的IP地址发送给第一物理机，将第二物理机上的全部虚拟机的IP地址发送给第二物理机。除此之外，每一虚拟机均关联了对端虚拟机，控制设备还会将第一物理机上各个虚拟机关联的虚拟机的IP地址发送给第一物理机，将第二物理机上各个虚拟机关联的虚拟机的IP地址发送给第二物理机。
为实现第一物理机与第二物理机在局域网内能够通信，控制设备需要为第一物理机和第二物理机分别配置IP子网段，并且需要保证第一物理机的IP子网段与第二物理机的IP子网段在同一网段内。例如，控制设备为第一物理机分配的IP子网段为192.168.1.X，控制设备为第二物理机分配的IP子网段为192.168.2.X，这两个子网段均位于网段192.168.X.X范围内。
进一步的，控制设备为第一物理机和第二物理机分别配置IP子网段后，还需要为第一物理机和第二物理机分配若干个虚拟机的IP地址，虚拟机的数量由控制设备决定。并配置第一物理机的每个虚拟机IP地址与第二物理机的每个虚拟机IP地址的映射表。例如，第一物理机的IP子网段为192.168.1.X，第二物理机的IP子网段为192.168.2.X，控制设备分别为第一物理机和第二物理机分配3个虚拟机的IP地址，并配置位于第一物理机中的每一个虚拟机的IP地址与第二物理机中每个虚拟机的IP地址的关联关系。这里，“关联”是指如果两个物理机上的虚拟机被分配的IP地址是关联的，则这两台虚拟机建立了心跳链路，需要互相发送并响应心跳报文。例如，IP地址映射表的格式及内容可以例如但不限于如下表1所示。
表1
Figure PCTCN2019102769-appb-000001
可选的，控制设备为各个物理机分配了IP子网段以及为各个物理机上的虚拟机分配了IP地址映射表后，可以将IP地址映射表发送给交换机，交换机根据IP地址映射表进行报文转发。例如，控制设备发送给交换机的IP地址映射表可以例如但不限于表1所示。
此外，控制设备还需要将为各个物理机分配的IP子网段以及虚拟机的IP地址映射表发送给各个物理机。以第一物理机为例，控制设备需要将为第一物理机分配的IP子网段192.168.1.X发送给第一物理机，还需要将第一物理机上各个虚拟机的IP地址以及与其对应的虚拟机的IP地址映射表发送给第一物理机。例如，控制设备向第一物理机发送的IP地址映射表可以例如但不限于下表2所示。
表2
Figure PCTCN2019102769-appb-000002
当然，控制设备发送给第一物理机的IP地址映射表也可以如表1所示。
相应的，控制设备需要将为第二物理机分配的IP子网段192.168.2.X发送给第二物理机以外，还需要将第二物理机上各个虚拟机的IP地址以及与其对应的虚拟机的IP地址映射表发送给第二物理机。例如，控制设备向第二物理 机发送的IP地址映射表可以例如但不限于下表3所示。
表3
Figure PCTCN2019102769-appb-000003
当然，控制设备发送给第二物理机的IP地址映射表也可以如表1所示。
可选的，物理机接收控制设备发送的IP地址映射表后，根据IP地址映射表创建虚拟机，例如，第一物理机接收到控制设备发送的如表2的IP地址映射表后，第一物理机根据表2创建3台虚拟机，分别为虚拟机1、虚拟机2和虚拟机3，并且根据控制设备为其分配的虚拟机IP地址分别为各个虚拟机分配IP地址。例如，为虚拟机1配置的IP地址为：192.168.1.102，为虚拟机2配置的IP地址为：192.168.1.68，为虚拟机3配置的IP地址为：192.168.1.94。同样的，第二物理机接收到控制设备发送的如表3所示的IP地址映射表后，根据表3创建3台虚拟机，分别为虚拟机4、虚拟机5和虚拟机6，并根据控制设备为其分配的虚拟机IP地址分别为各个虚拟机分配IP地址。例如，为虚拟机4配置的IP地址为：192.168.2.104，为虚拟机5配置的IP地址为：192.168.2.70，为虚拟机6配置的IP地址为：192.168.2.96。
可选的，第一物理机发送的第一心跳报文是第一物理机上某一虚拟机(为便于描述，以虚拟机1为例)发送给第二物理机上的某一虚拟机(为便于描述，以虚拟机4为例)的。第一物理机根据虚拟机1的IP地址和IP地址映射表将虚拟机1发送的第一心跳报文的目的IP地址设置为与虚拟机1匹配的目的IP地址。例如，第一物理机根据虚拟机1的IP地址192.168.1.102，从IP地址映射表1中确定目的IP地址192.168.2.104，第一物理机将虚拟机1发送的心跳报文的目的IP地址设置为192.168.2.104。
交换机接收到第一物理机发送的第一心跳报文后，对第一心跳报文的目的IP地址进行解析，根据IP地址映射表找到192.168.2.104地址对应的为第二物理机，然后将第一心跳报文发送给第二物理机。
实施本申请实施例，控制设备可以为网络中的各个物理机上的虚拟机分配IP地址，并发送给交换机，使得交换机可以基于各个虚拟机的IP地址对虚拟 机之间传输的心跳报文进行转发处理。
可选的，第一虚拟机和第二虚拟机的关系可以是主备虚拟机，其中第一虚拟机为主虚拟机，第二虚拟机为备虚拟机。主机可以周期性向备机发送心跳报文，备机可以检测主机是否周期性发送心跳报文来识别主机是否处于正常工作状态，若备机在一段时间内未收到主机发送的心跳报文，则备机判定主机发生故障，则备机升级为主机继续执行主机的操作。
可选的，上述交换机为交换机集群中的主交换机，所述交换机集群中包括至少两台交换机，在主交换机出现故障后交换机集群中可以选举新的主交换机替换故障交换机继续与第一物理机、第二物理机和控制设备进行上述交互。
具体的，交换机集群中的交换机中存储有与主交换机相同的数据内容。
实施本申请实施例，通过主备集群的设置能够提升整个通信***的可靠性，避免数据在主交换机发生故障后丢失。
参见图4，图4示给出了一种控制设备的逻辑结构示意图，如图4所示，该控制设备400包括：接收单元401和处理单元402。
其中，接收单元401，用于接收交换机发送的第一指示信息，所述第一指示信息用于指示所述交换机接收到第一虚拟机发往第二虚拟机的第一心跳报文，所述第一虚拟机为第一物理机上配置的一个或多个虚拟机中的一个，所述第二虚拟机为第二物理机上配置的一个或多个虚拟机中的一个；
