System and method for detecting a virtual extensible local area network (VXLAN) segment data path failure

摘要

Methods and apparatuses for determining a VXLAN data path failure are provided. In an embodiment, a first data packet comprising an echo request is generated at an originating tunnel end point device in a network. The echo request includes a VXLAN network identifier (VNI) associated with a selected VXLAN segment. A second data packet is generated comprising a header having a format associated with a VXLAN technology, the header comprising a network identifier portion including the VXLAN network identifier (VNI). The first data packet is encapsulated in the second data packet, and the second data packet is transmitted via the selected VXLAN segment.

1. A method for determining a VXLAN data path failure, the method comprising:
generating, at an originating tunnel end point device in a network, a first data packet comprising an echo request, the echo request including a VXLAN network identifier (VNI) located in a payload portion of the echo request, wherein the VNI identifies a selected VXLAN segment and is used to generate an echo reply in response to the echo request; generating a second data packet comprising a header having a format associated with a VXLAN technology, the header comprising a network identifier portion including the VNI; encapsulating the first data packet in the second data packet; transmitting the second data packet to a destination node via the selected VXLAN segment; receiving the echo reply in response to transmitting the second data packet to the destination node, the echo reply including a port number of the destination node; and determining whether there is a failure in the selected VXLAN segment by matching the echo reply with the echo request based on the port number.
