Abstract

This disclosure provides a VXLAN message processing device, which is arranged at the network node that terminates the VXLAN message, including: a mapping table creation component, which obtains all VXLAN tunnel IPs and network identifiers VNI in the specified network, and provides each group of VXLAN tunnel IPs and network Identify the VNI and the corresponding VXLAN encapsulation header information to create a mapping entry, and store all the mapping entries as a mapping table in the mapping table storage unit; the parsing unit parses the received message and obtains the header information of the message; the mapping table lookup component , querying the mapping table based on the obtained header information, and obtaining a mapping entry corresponding to the header information; and an encapsulation and decapsulation unit, based on the queried mapping entry, encapsulating or decapsulating the message.

Description

technical field

[0001] The disclosure relates to a message processing device and a data processing method, in particular to a message processing device and a data processing method in a virtual scalable local area network environment. Background technique

[0002] In a VLAN network environment, all data streams need to pass clear network addressing to ensure that they reach their destinations accurately. Therefore, the size of the Layer 2 address entry of the network device becomes the upper limit of the size of the virtual machine in the cloud computing environment. The current mainstream network isolation technology is VLAN (or VPN). The number of VLANs is only 12 bits in the standard definition, that is, the available number is about 4000. Such an order of magnitude is negligible for public cloud or large-scale virtualized cloud computing applications. .

[0003] In order to solve the above problems, VXLAN technology emerges as the times require. VXLAN (Virtual Extensib...
