Embodiment Construction

[0166] In Layer 2 networks such as VxLAN and VLAN, in order to improve the reliability of data transmission, it is usually necessary to detect the connectivity between MAC addresses in the same broadcast domain. For example, for VxLAN, what is mainly needed at present is to detect connectivity between MAC addresses with the same VxLAN network identifier (English: Virtual Network Identifier, VNI for short).

[0167] In some Layer 2 networks, the Mac Ping function of IEEE 802.1g ETHOAM can be used to detect the connectivity between MAC addresses in the same broadcast domain. According to the IEEE 802.1g protocol, when using the Mac Ping function, you first need to configure the MD in the layer 2 network, and configure the MA in the MD according to the service instance. The border node of the configured MA is called MEP, and the intermediate node is called MIP. . After the MA and MD are configured, the maintenance node and the remote maintenance node are determined from the MEP ...

Abstract

The invention provides a layer-2 network connectivity detecting method and associated equipment which are used for detecting connectivity of a first MAC (media access control) address and a second MAC address belonging to the same broadcast domain. The method comprises steps as follows: a controller sends a first MAC flow-table entry or data indicating generation of the first MAC flow-table entry to a first switch; the first MAC flow-table entry comprises a first matching item and a first action, the first action is used for indicating the first switch to be matched with a first message according to the first matching item and uploading the first message to the controller; the controller detects the connectivity of the first MAC address and the second MAC address according to the result of the judgment whether the first message is received in preset time. Accordingly, the connectivity of the first MAC address and the second MAC address belonging to the same broadcast domain can be detected through issuing of the flow-table entry without a complicated parameter configuration process, so that the workload is reduced.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a method for detecting connectivity of a two-layer network and related equipment. Background technique [0002] In Layer 2 networks such as virtual extensible local area network (English: Virtual eXtensible Local Area Network, referred to as VxLAN) and virtual local area network (English: Virtual Local Area Network, referred to as VLAN), in order to improve the reliability of data transmission, it is usually necessary to Connectivity between MAC addresses belonging to the same broadcast domain is detected. [0003] At present, in some Layer 2 networks, the Institute of Electrical and Electronics Engineers (English: Institute of Electrical and Electronics Engineers (abbreviation: IEEE) 802.1g Ethernet operation, management and maintenance (English: Operations, Administration and Maintenance of Ethernet, abbreviation: ETHOAM) Mac Ping function. According to the IEEE 802.1g...
