Abstract:
A path detection method in a virtual extensible local area network (VxLAN), a controller, and a network device, where the controller constructs a detection packet according to a detection request and sends the detection packet to a source network device corresponding to a source VxLAN tunnel endpoint (VTEP). The source network device forwards, level by level, the detection packet to a destination network device corresponding to a destination VTEP, and reports information such as an Internet Protocol (IP) address, an outbound interface number, and an inbound interface number to the controller level by level. Therefore, a real service path may be detected.

Claim (Index 2):
The method of  claim 1 , wherein the detection request comprises an IP address of a source virtual machine, an IP address of a destination virtual machine, and a protocol type identifier and constructing the detection packet comprising:\n capturing, by the controller, a target packet according to the IP address of the source virtual machine, the IP address of the destination virtual machine, and the protocol type identifier in the detection request; obtaining, by the controller, a port number of the source virtual machine of the target packet and a port number of the destination virtual machine of the target packet to obtain 5-tuple information, the 5-tuple information comprising the IP address of the source virtual machine, the IP address of the destination virtual machine, the protocol type identifier, the port number of the source virtual machine, and the port number of the destination virtual machine; determining, by the controller, the source port value according to the 5-tuple information; determining, by the controller, the endpoint identifier of the source VTEP according to the IP address of the source virtual machine; determining, by the controller, the endpoint identifier of the destination VTEP according to the IP address of the destination virtual machine; obtaining, by the controller, the IP address of the first network device corresponding to the endpoint identifier of the source VTEP; and determining, by the controller according to the detection request, that the path detection type comprises path detection between virtual machines.
