Embodiment Construction

[0022] The present invention utilizes reconfigurable technology to realize the access of supporting two modes of 10GE and 10GPOS at the same time, and can automatically select the current network protocol in an adaptive way, and can also perform arbitrary access to the two interfaces according to the configuration of the software Mode selection, such as two 10GE or two 10GPOS or one 10GE plus one 10GPOS, to flexibly support 10G bandwidth access in different network environments.

[0023] can refer to attached figure 1 And attached figure 2 , with figure 1 For the overall structure diagram, attached figure 2 For the specific control structure diagram.

[0024] attached figure 1 Among them, the high-speed serial-to-parallel conversion module uses an ASIC chip to convert the serial data stream of 10.3125Gbps (10GE environment) or 9.95328Gbps (10GPOS environment) into parallel data and input it to the reconfigurable device; the channel selection module is configured accordin...

Abstract

The invention provides a mixed-mode high-speed front end network access processing method. A high-speed serial-parallel conversion unit converses two paths of data and input the converted data into a reconfigurable device; a channel selection module branches network data according to software configuration; a 10GE processing unit and a 10GPOS processing unit respectively process 10GE and 10GPOS physical layer and data link layer protocols, independently; and a data merging unit merges data flows into one data flow for use of following network information processing units. The mixed-mode high-speed front end network access processing method implements the packet capturing and the treatment under various high-speed network environments, so multiple investments are avoided, and cost is saved.

Description

technical field [0001] The invention relates to the field of high-speed network information processing, in particular to a mixed-mode high-speed front-end network access processing method. Background technique [0002] In the 10G network environment, there are mainly two protocol access modes, 10GE and 10GPOS. Due to the different protocols, in a single interface, the method of independently implementing the above-mentioned protocol access mode is generally adopted, and a few network test equipment can have both. In the access mode, even if there are multiple ports, it is generally implemented by configuring a single port to support a single protocol mode, instead of implementing two protocols through self-adaptation on multiple ports. [0003] Most of the current high-speed network access devices are implemented by dedicated chips, and the cost of implementing two mixed-protocol interfaces at the same time is relatively high. Generally, only a single interface is used to im...
