Problems solved by technology

In this way, sending each frame of network message to the LINUX protocol stack for processing will increase the processing time of the network message in the LINUX protocol stack, which will greatly limit the transmission efficiency and rate of the network message, thereby limiting network throughput

Embodiment Construction

[0035] The technical solution of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0036] The invention is based on the Ethernet-driven data forwarding method, combines PHP and Ethernet-driven routers to process the transmission data, adjusts the LINUX-based Ethernet driver's data transmission and reception process, and skips normal and redundant Ethernet Driven data processing flow, thereby reducing the processing time of data in the LINUX protocol stack.

[0037] In the present invention, the forwarding of the network message without being processed by the LINUX protocol stack is called fast forwarding.

[0038] The network message exists in the form of a data packet in the data processing flow of the present invention. The processing of the network message by the driving receiving end is based on the descriptor of the packet header. The descriptor is a field in the packet header used to describe the data pa...

Abstract

The invention discloses a data forwarding method based on an Ethernet driver, which comprises the following steps: a packet header processor (PHP) confirms that a current data packet needs to be quickly forwarded and finds a matching quick forwarding entrance of the current data packet in a quick forwarding table; after verifying that the current data packet is a TCP control message but not a transmission control protocol (TCP) control message or the current data packet is not a timeout user datagram protocol (UDP) message, a driver receiving terminal sends the current data packet to a driversending terminal through the quick forwarding port; the driver sending terminal forwards the data packet. The invention further discloses a data forwarding device based on the Ethernet driver, and based on the method and the device of the invention, the processing time of data packets in the LINUX protocol stack can be saved.

Description

technical field [0001] The present invention relates to data transmission technology, in particular to an Ethernet-driven data forwarding method and device. Background technique [0002] With the rapid development of network technology, the data volume of various business types such as voice and telephone data, real-time video data, and Internet browsing data in the network has increased sharply; at the same time, ordinary home users have more and more requirements for network transmission quality and network bandwidth. high. Obviously, the data transmission based on the Ethernet router is bound to become an important direction of future development. [0003] At present, compared with the uplink router based on Asymmetric Digital Subscriber Line (ADSL, Asymmetric Digital Subscriber Line), the uplink router of Ethernet based on LINUX has greatly improved its performance, but it is still in the forwarding of network packets. There is a bottleneck, and the so-called bottlenec...
