Problems solved by technology

[0004] However, due to the large number of virtual machines in the large layer-2 network used by the data center, and the MAC (Media Access Control, physical address) address on the virtual machine is generated by the software of the virtual machine management platform, it is used on different virtualization platforms. In the case of the network, there will inevitably be MAC address conflicts in the network, and the MAC address conflicts may affect the normal communication

Abstract

The present disclosure provides a method, device and machine-readable storage medium for processing conflicting MAC addresses. The method includes: sending monitoring flow entries to each switch, receiving an OpenFlow message carrying a copied ARP protocol message, and according to the sending end MAC address host table entry, determine the MAC address of the sending end and the MAC address of the found host table entry as a conflicting MAC address, use the hosts corresponding to the conflicting MAC address as the first host and the second host, and connect to the first host. A switch sends a first hosting flow entry hosting the ARP protocol message from the first host, and sends a second hosting flow entry hosting the ARP protocol message from the second host to a second switch connected to the second host. In this way, the conflicting MAC address can be found in time, and the ARP protocol message corresponding to the conflicting MAC address can be managed, thereby improving the reliability of communication.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and in particular to a method, device and machine-readable storage medium for processing conflicting MAC addresses. Background technique [0002] With the development of large-scale data concentration and the application of virtualization technology, the scale of data centers is increasing day by day, which not only requires a larger area of ​​the Layer 2 network, but also poses new challenges in terms of requirements and management levels. [0003] As the size of the data center area and business processing requirements increase, there are more and more applications for cluster processing. The servers in the cluster need to be in a Layer 2 VLAN (Virtual Local Area Network, Virtual Local Area Network) or VXLAN (Virtual Extensible LAN, Virtual Extended Local Area Network) )Down. At the same time, on the basis of the convenience and flexibility of business deployment brought by the a...
