一种OAM报文处理方法、网络设备和网络系统
摘要：
一种OAM报文处理方法、网络设备和网络系统。其中该方法包括：接收第一IP包，所述第一IP包中包含OAM报文，所述OAM报文的IP包头部包括第一OAM信息；所述第一OAM信息包括第一源设备ID、第一宿设备ID；返回第二IP包，对所述OAM报文进行回复，所述第二IP包中包含OAM回复报文，所述OAM回复报文的IP包头部包括与所述第一OAM信息相对应的第二OAM信息；所述第二OAM信息包括第二源设备ID、第二宿设备ID、第二报文类型，其中，所述第二源设备ID为本地网络设备的ID，所述第二宿设备ID与所述第一源设备ID相同。可利用IP包头部携带OAM信息，提高了OAM方法故障侦测的能力。
摘要（英）：

An OAM packet processing method, a network device, and a network system are disclosed. The method includes: receiving a first IP packet, where the first IP packet includes an OAM packet, an IP packet header of the OAM packet includes first OAM information, and the first OAM information includes a first source device ID and a first sink device ID; and returning a second IP packet to reply to the OAM packet, where the second IP packet includes an OAM reply packet, an IP packet header of the OAM reply packet includes second OAM information corresponding to the first OAM information, the second OAM information includes a second source device ID, a second sink device ID, and a second packet type, the second source device ID is an ID of a local network device, and the second sink device ID is the same as the first source device ID. An IP packet header may be used to carry OAM information, which improves a fault detection capability in an OAM method.
