Abstract

The invention provides a data transmission method, device and system based on programmable network switching technology, a storage medium and equipment. The method comprises the following steps of receiving a data packet packaged by a tunnel protocol; analyzing header information of the data packet based on the format of the tunnel protocol to form analyzed metadata; analyzing a metadata value corresponding to a matching field configured in the flow table in the metadata; querying a flow table item of the flow table, the flow table item comprising a field value of a matching field and a parameter value of an action configured in the flow table, the matching field comprising a user ID and an inner layer quintuple, and the action being that a data packet matched with the flow table item is output to a port corresponding to the parameter value; and outputting the data packet to a port corresponding to the parameter value according to the flow table item.

Description

technical field

[0001] The invention relates to the field of programmable network hardware switches, in particular to a method, device, system, storage medium and equipment for data transmission based on programmable network switching technology. Background technique

[0002] In the cloud computing environment, in order to meet the high performance, flexibility, and scalability of the business, the SDN solution uses Open vSwitch on the forwarding plane, and more and more self-developed high-performance forwarding clusters are used on the forwarding plane. , such as the dpdk cluster. In order to achieve high availability, the dpdk cluster is usually used in combination with the traditional switch bgp+ecmp.

[0003] However, compared with the programmable switch, the dpdk cluster has the following technical defects:

[0004] 1. Limited by the CPU and network card, it is impossible to achieve higher wire speed forwarding, usually 10G wire speed, 25G wire speed, and programmab...
