Title
(EN) Message processing method, device and system
(ZH) 一种处理报文的方法、设备及系统
Abstract
(EN)
The invention discloses a method, equipment and a system for processing a message. The method comprises the steps that a first network device sends a first VXLAN message to a second network device through an NAT device, and the first VXLAN message comprises a first destination port number and a first source port number; and the first network device receives a fourth VXLAN message sent by the NAT device through a VXLAN tunnel, wherein the value of a fourth destination port number included in the fourth VXLAN message is equal to the value of the first source port number. And the first network device processes the fourth VXLAN message according to a VXLAN protocol after determining that the fourth destination port number is the same as the first source port number.

(ZH)
一种处理报文的方法、设备及系统。所述方法包括,第一网络设备经由NAT设备向第二网络设备发送第一VXLAN报文,所述第一VXLAN报文包括第一目的端口号和第一源端口号。所述第一网络设备经由VXLAN隧道接收所述NAT设备发送的第四VXLAN报文,所述第四VXLAN报文包括的第四目的端口号的值等于所述第一源端口号的值。所述第一网络设备确定所述第四目的端口号与所述第一源端口号相同后,根据VXLAN协议处理所述第四VXLAN报文。
