Method and device for achieving virtual extensible local area network (VXLAN) message transmitting in application specific integrated circuit (ASIC)

Abstract

The invention discloses a method and device for achieving virtual extensible local area network (VXLAN) message transmitting in an application specific integrated circuit (ASIC). The VXLAN message transmitting is completed through treatment of a VXLAN gateway between a server and an internet protocol (IP) network, the transmitted message comprises uplink message and downlink message, the uplink message is message transmitted from a server side to the IP network, a treatment process comprises analyzing received message and judging whether transmitting treatment is needed or not; obtaining corresponding VXLAN ID of the message needing transmitting; and using the VXLAN ID and a message destination MAC address lookup table to obtain treatment information and transmitting port information of the message, and transmitting the message to be transmitted after packaging treatment. The method and device achieves actions of unicast, multicast and the like of the VXLAN message, and achieves transition from a VLAN transmitting area to a transmitting area based on the VXLAN through logical solidification in the ASIC.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and a device for realizing VXLAN message forwarding in ASIC (Ethernet switching chip) design. Background technique [0002] With the gradual development of virtualization and cloud computing, future data centers will deploy a large number of virtual machine applications. In order to control the communication between different virtual machines and between virtual machines, and between virtual machines and tenants, VLAN (Virtual Local Area Network, Virtual Local Area Network) has naturally become a means of isolating different local area networks. However, due to the wide application of virtual technology, the number of tenants that can be supported in a data center has also greatly increased, and the layer 2 MAC addresses will experience explosive growth, and in theory, MAC addresses in different virtual LANs can overlap. Therefore, the number of original 4K VLANs ha...
