A Routing Control System Used to Interact Between Custom High-Speed ​​Interface and Ethernet

Abstract

The invention discloses a routing control system for interaction between a self-defined high-speed interface and Ethernet, including a business code identification and detection module, an Ethernet sending control module, an Ethernet receiving control module, a routing configuration module, and several self-defined high-speed channel data receiving control module, several high-speed data sending buffer FIFOs, several routing information buffering FIFOs, several high-speed data receiving buffering FIFOs, and several self-defined high-speed channel data sending control modules; the self-defined protocol optical data of the present invention adopts the business number as the routing information carrier, reducing The length of the routing information carrier is increased, the bandwidth utilization rate is improved, the efficiency of routing information analysis is improved, the delay time of data forwarding is reduced, and data routing and forwarding of multi-channel and multi-service can be supported; relevant routing information is configured in a software-defined manner, The configuration information is flexible and changeable, which is especially suitable for the scenario of increasing business in the later stage, without redesigning software and hardware, which simplifies the design and development process and shortens the design and development cycle.

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
