A routing control system for user-defined high-speed interface interaction with the Ethernet

Abstract

The invention discloses a routing control system for user-defined high-speed interface and Ethernet interaction. The system comprises a service code identification detection module. Ethernet transmission control module, The system comprises an Ethernet receiving control module, a route configuration module, a plurality of user-defined high-speed channel data receiving control modules, a pluralityof high-speed data sending cache FIFOs, a plurality of route information cache FIFOs, a plurality of high-speed data receiving cache FIFOs and a plurality of user-defined high-speed channel data sending control modules. According to the self-defined protocol optical data, the service number is adopted as the routing information carrier, the length of the routing information carrier is reduced, thebandwidth utilization rate is increased, the routing information analysis efficiency is improved, the data forwarding delay time is shortened, and multi-channel and multi-service data routing forwarding can be supported; A software definition mode is adopted to configure related routing information, the configuration information is flexible and variable, the method is particularly suitable for later service adding scenes, software and hardware do not need to be designed again, the design and development process is simplified, and the design and development period is shortened.

Description

【Technical field】 [0001] The invention belongs to the field of embedded system communication, and relates to a routing control system for interaction between a self-defined high-speed interface and an Ethernet. 【Background technique】 [0002] As the demand for data services increases unprecedentedly, the demand for communication performance of network equipment also increases. In the existing high-performance information processing platform, optical fiber is used as the transmission medium for data communication outside the platform, and 40G Ethernet is used for inter-board interconnection within the platform to achieve high-bandwidth data transmission. Because there is no standard protocol requirement for optical data, the processor cannot be used to complete the analysis and interaction between optical data of custom protocols and 40G Ethernet data. It is necessary to use the FPGA chip to analyze and package the custom protocol optical data and 40G Ethernet data. Due to ...

Problems solved by technology

When adding all routing field information, this method uses more bytes, takes up effective bandwidth, and takes a long time to parse routing information; when adding part of routing field information, the source / destination MAC address and UDP / IP related information cannot be flexibly changed. Poor compatibility, if you want to achieve adaptation with other systems, you need to re-modify the logic code and implement the project, the rectification period is long, and there is a risk of routing failure

And with the great improvement of communication performance brought by 40G Ethernet, the custom optical data channel will change from single channel to multi-channel, and the communication data will change from single service to multi-service. The existing methods can no longer meet the complex multi-channel Data routing operation of multi-service data and multi-destination network nodes
