Abstract:
A path detection method and apparatus, where the method includes generating M virtual extensible local area network (VXLAN) probe packets according to a source User Datagram Protocol (UDP) port number, a destination UDP port number, and a probe identifier when there are multiple equivalent paths between a source VXLAN tunnel endpoint (VTEP) and a destination VTEP, sending the M VXLAN probe packets to the source VTEP to forward the M VXLAN probe packets to the destination VTEP, receiving VXLAN advertisement packets from the source VTEP, the destination VTEP, and intermediate nodes in the multiple equivalent paths according to the M VXLAN probe packets, and detecting, according to the VXLAN advertisement packets, whether a fault occurs in a path of the multiple equivalent paths between the source VTEP and the destination VTEP.

Claim (Index 4):
The method according to  claim 1 , wherein generating the M VXLAN probe packets comprises:\n performing a hash operation on each of N consecutive source UDP port numbers and an Internet Protocol (IP) address of the source VTEP, an IP address of the destination VTEP, a Layer 4 port number of the destination VTEP, and a protocol type between the source VTEP and the destination VTEP to obtain hash values, wherein N comprises a maximum value of the source UDP port numbers, and wherein N comprises a positive integer greater than or equal to two; grouping the N consecutive source UDP port numbers into M first sets according to the hash values, wherein hash values corresponding to all source UDP port numbers in each of the M first sets are equal, and wherein M is less than or equal to N; obtaining a source UDP port number from each of the M first sets to form a second set; and generating the M VXLAN probe packets according to each source UDP port number in the second set, the destination UDP port number, and the probe identifier.
