Abstract

The invention discloses a mapping method and system and a related device and relates to the field of data communication. According to the method, the system and the related device, a switch sends a request message for establishing mapping to a management platform in response to a received data packet, so the management platform can establish a mapping relationship among virtual local area networkidentifiers of virtual machines, switch ports accessed by the virtual machines and tenant identifiers. The practically existing mapping relationship in a network can be generated according to a demand, so the redundant mapping relationship is prevented from being generated. A memory space of the switch is reduced. The searching efficiency of the mapping relationship and the forwarding efficiency of the data packet are improved.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a mapping method, system and related equipment. Background technique [0002] At present, as the software-defined network technology continues to mature, more and more data centers begin to adopt overlay network technologies such as Virtual Extensible LAN (VxLAN, Virtual Extensible LAN) to form a large layer-2 virtualized network. [0003] For platforms that cannot deploy overlay network technology, traditional virtual local area network (VLAN, Virtual Local Area Network) technology is still used for network isolation. Therefore, it is necessary to consider the compatibility and interconnection of overlay networks such as VxLAN and VLAN networks. [0004] In existing solutions, a software-defined network hardware access switch is often introduced as a VxLAN gateway to realize the mapping and intercommunication between the VxLAN network and the VLAN network. This solution needs...
