Problems solved by technology

However, the existing technology using VTEP cannot flexibly define the forwarding path of the inner layer message according to the needs after decapsulating the general VXLAN protocol, and can only determine the forwarding path according to the inner layer message information
In addition, the outer layer information encapsulated by the general VXLAN protocol cannot be flexibly defined according to the needs, and can only be encapsulated according to the tunnel information associated with the inner layer packet forwarding path
Moreover, general-purpose VTEP cannot be used as a transparent gateway device for adding / decapsulating

Abstract

The invention provides a VXLAN (Virtual Extensible Local Area Network) message processing device arranged at a network node for terminating a VXLAN message. The device comprises a mapping table creation component used for acquiring all VXLAN tunnel IPs and network identifiers VNIs in a specified network, creating mapping entries for each group of VXLAN tunnel IPs and network identifiers VNIs and the corresponding VXLAN encapsulation header information, and storing all mapping entries as mapping tables in a mapping table storage unit; an analysis unit used for analyzing the received message andacquiring header information of the message; a mapping table searching component used for querying a mapping table based on the obtained header information and obtaining a mapping entry correspondingto the header information; and an encapsulation and de-encapsulation unit used for encapsulating or de-encapsulating the message based on the inquired mapping entry.

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...
