Problems solved by technology

[0005] The routing process of IP has gone through three processes of data receiving, forwarding path finding and data sending. In general, all data packets of a connection will be forwarded using the same path, and the CPU needs to be processed on the protocol stack, which seriously reduces speed of message forwarding

Embodiment Construction

[0022] In order to improve the forwarding speed, when the embodiment of the present invention receives a data message, obtain the quintuple information of the data message, and judge whether the data message is a forwarding message; if it is a forwarding message, then according to the preserved forwarding table The forwarding path corresponding to the quintuple information forwards the data message; if it is not a forwarded message, after the data message is processed by the protocol stack, the routing information of the data message is obtained, and then sent according to the routing information the datagram.

[0023] see figure 1 As shown, the data packet forwarding method in the embodiment of the present invention includes the following steps:

[0024] Step 101: When the network card terminal processing unit recognizes that the network card has received a data packet, call the hard interrupt processing unit for processing. Specifically, the network card terminal processin...

Abstract

The invention discloses a method and a device for data message forwarding. The method and the device aim at improving message forwarding speed. The method includes that when a network card terminal processing unit recognizes that a network card receives a data packet, a hardware interrupt processing unit is invoked to process, the hardware interrupt processing unit applies for an fk_buff data storage structure to copy the data packet into a data area of the fk_buff from the internet card, whether the data packet meets forwarding conditions or not is determined, if yes, a quick forwarding module obtains a corresponding forwarding path according to forwarding entries in a forwarding table set by quintuple information indexes of a data message and utilizes a hardware sending function to forward the data packet in the data area of the fk_buff, and if not, the fk_buff is taken as data of sk_buff to upload to a protocol stack for processing.

Description

technical field [0001] The invention relates to a data forwarding technology on a Linux operating system, in particular to a data message forwarding method and device. Background technique [0002] The fierce competition in the IT industry and the continuous decline in product prices have brought severe challenges to IT companies. Everyone has turned their attention to the low-cost embedded (Linux) operating system, and the popularity and development of Linux has begun. For terminal network products, Linux is undoubtedly a good choice for the operating system. [0003] And with the development of the network, the use of IP networks is becoming more and more extensive. Almost everyone has experience in using the network to query data, e-mail back and forth, and play online games. In this case, users have higher and higher requirements for network speed. [0004] However, at present, the routing process of non-locally generated data packets in an optical network access term...
