Embodiment Construction

[0043] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0044] The embodiment of the present invention provides a message forwarding method. Through the learning of the message, the PP (Packet Processor, message processor) is dynamically configured, and the modification and forwarding of the message are directly completed by using the PP, so that the performance of the gateway can be greatly improved. Promote.

[0045] As the core of hardware forwarding messages, PP can support IPv4 (Internet Protocol Version 4), IPv6 (Internet Protocol Version 6), PPPoE message identification, quintuple information matching; support for modifying MAC addresses, NAT translation, VLAN addition and deletion, and PPPoE header addition and deletion; support for counting the matching times of packets for software qu...

Abstract

The invention provides a message forwarding method and device. The method comprises the steps that a software acceleration item for modifying attribute information of a first message recorded in the forwarding process of the first message is acquired; the first number of second messages which meet the software acceleration item and require to be forwarded is acquired in the first preset period of time after forwarding the first message; a hardware acceleration item is configured for the second messages required to be forwarded according to the first number; and the subsequent second messages required to be forwarded are forwarded according to the hardware acceleration item. According to the method and the device, cooperation of the software and the hardware can be realized, the hardware acceleration item is configured by learning the messages and modification and forwarding of the messages can be directly completed by using a message processor so that the gateway performance can be greatly enhanced, the performance requirement of the gateway product can be met, the hardware cost can also be reduced and the method and the device have economic value and reference value.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method and device for message forwarding. Background technique [0002] As the national network speeds up, the data load of gateway products has increased dramatically. When processing network packets, many of them are processed by protocol stack software. Although the performance of the CPU (Central Processing Unit) has been greatly improved, it is still overwhelmed compared to a large number of packet forwarding; , The message needs to be modified, such as MAC (Media Access Control, hardware address) address translation, NAT (Network Address Translation, network address translation), adding and deleting business service types of VLAN (Virtual Local Area Network, virtual local area network) and Adding and deleting PPPoE (Point to Point Protocol over Ethernet, Point to Point Protocol over Ethernet) first class, which greatly consumes CPU resources, and aggravates the burden on...
