Embodiment Construction

[0092] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0093] Under the VxLAN networking architecture, the data packet sent by the VM is encapsulated in UDP, and the IP / MAC of the physical network is used as the outer-header for encapsulation, and then transmitted on the physical IP network. After reaching the destination, the VTEP decapsulates and sends Data is sent to the target virtual machine. Multiple VMs can be attached to one VTEP. In the embodiment of the present invention, the controller can detect a single net...

Abstract

This application provides a path detection method in VxLAN, a controller and a network device. The controller constructs a detection message according to the detection request and sends it to the source network device corresponding to the source VxLAN tunnel endpoint (VTEP), forwards it to the destination network device corresponding to the destination VTEP through the source network device step by step, and reports the IP address, Information such as the outgoing interface number and incoming interface number can detect the real service path.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a path detection method, a controller and a network device in a virtual extensible local area network (Virtual Extensible Local Area Network, referred to as VxLAN). Background technique [0002] Software Defined Network (SDN for short) is an implementation method of network virtualization, which can separate the control plane and data plane of network equipment through the Open Flow Forwarding Protocol (OpenFlow), thereby realizing the flexibility of network traffic control, making the network as a conduit smarter. [0003] VxLAN is an overlay network technology or tunnel technology. Under the VxLAN networking architecture, the data packets sent by the virtual machine (Virtual Machine, VM for short) are encapsulated in the User Datagram Protocol (UDP for short), and the Internet Protocol / Media Access Control layer ( Internet Protocol / MediaAccess Contol, referred ...
