Data forwarding method and device thereof, storage medium and network card equipment

Abstract

The invention relates to the field of the communication, and discloses a data forwarding method and device thereof, a storage medium and network card equipment. The data forwarding method comprises the following steps: receiving a connection header message of to-be-forwarded data forwarded by the network card equipment; acquiring a source address and a destination address in the connection headermessage; determining a forwarding rule corresponding to the source address according to the acquired source address and destination address; sending the forwarding rule to the network card equipment,thereby enabling the network card equipment to directly forward the subsequent message of the to-be-forwarded from the first terminal to the second terminal according to the forwarding rule after a data transmission relation is established between the first terminal corresponding to the source address and the second terminal corresponding to the destination address. The network data forwarding with a firewall function is realized through the software and hardware combination way, the complexity of realizing the technology only based on the software is reduced, and the network data forwarding performance under the cloud computation environment is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a data forwarding method and its device, storage medium and network card equipment. Background technique [0002] Software Defined Network (SDN) separates the control plane of network equipment from the data plane, thereby realizing flexible control of network traffic and making the network more intelligent as a pipeline. In the cloud computing environment, users' requirements for the network are becoming more and more complex, such as isolation by tunnel technology, protection of the network from external attacks through firewall functions, and adoption of QoS (Quality of Service, service Quality) to control and manage user traffic, and use NAT (Network Address Translation, Network Address Translation) technology to provide external access capabilities. These requirements make the functions of SDN extremely complicated, and sometimes SDN alone cannot meet these performance requirements...

AI Technical Summary

Problems solved by technology

In the cloud computing environment, users' requirements for the network are becoming more and more complex, for example, the use of tunnel technology to achieve isolation, the use of firewall functions to prevent the network from external attacks, and the use of QoS (Quality of Service, service Quality) to control and manage user traffic, and use NAT (Network Address Translation, Network Address Translation) technology to provide external access capabilities. These requirements make the functions of SDN extremely complicated, and sometimes SDN alone cannot meet these performance requirements of users.
