Problems solved by technology

This makes the network structure complex
When a network failure requires maintenance, the complex links in the underlay network make it difficult to locate the faulty port and link, resulting in long maintenance time, low efficiency, and slow network recovery and communication.

Embodiment Construction

[0104] The technical solution of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments of the specification.

[0105] Such as figure 2 As shown, this embodiment provides a virtual extensible local area network VxLAN detection method, which is applied to a transmission node, and includes:

[0106] Step S110: detecting the sent detection message;

[0107] Step S120: When detecting a detection message, copy the detection message to form a copy message;

[0108] Step S130: Add the transmission information of the probe message transmitted at the transmission node to the copy message;

[0109] Step S140: Send the copy message with the transmission information added to the control node;

[0110] Step S150: Send the detection message to the next transmission node.

[0111] The transmission node may be a network node capable of transmitting the detection message, such as a virtual switch of a heavy-overlay network and a physical ...

Abstract

The embodiment of the invention discloses a V x LAN detection method and device, which are applied to a transmission node; the detection method comprises the following steps: detecting a sent detection message; when the detection message is detected, copying the detection message to form a duplicate message; adding transmission information transmitted by the detection message to the transmission node in the duplicate message; sending the duplicate message added with the transmission information to a control node; and sending the detection message to a next transmission node. In the embodiment,the detection message is duplicated, and the transmission information is added in the duplicate message, so that the transmission condition of the detection message in the transmission node can be known after the control node receives the duplicate message; therefore, whether the transmission node causes a network abnormal fault point or not is positioned according to the transmission condition;simple network fault positioning is realized, the fault positioning efficiency is improved, and the recovery speed of network communication is improved.

Description

Technical field [0001] The invention relates to a network detection technology in the communication field, in particular to a virtual extensible local area network (Virtualextensible Local Area Network, VxLAN) detection method and device. Background technique [0002] Such as figure 1 The VxLAN shown includes an overlay network and an underlying underlay network. A large number of primary links, backup links, and bundled links are configured in the underlying underlay network. This makes the network structure complicated. When the network fails and needs to be maintained, the complex links in the underlay network make it difficult to locate the port and link where the failure occurred, resulting in long maintenance time, low efficiency, and slow network recovery communication. Summary of the invention [0003] In view of this, the embodiments of the present invention are expected to provide a VxLAN detection method and device, and the indication part. [0004] In order to achieve...
