hinoc framing method, system, medium, computer equipment and application

Abstract

The invention belongs to the technical field of network data processing, and discloses a HINOC framing method, system, medium, computer equipment and application, relying on three state machines to extract, judge and update fragment information, and write and read frame data , and rely on three framing logics to realize data framing. The system includes: Fragment information preprocessing module, which realizes fragment information extraction, judgment, update and BD application; Fragment data processing module, realizes splicing and writing of fragment data and new EMAC frame data; Fragment data processing module, frame data processing Readout and framing. When the second-level pipeline state machine jumps out of the ENCAP_WRAM_IDLE state, it is judged whether the EMAC frame polled to the ping-pong fifo needs to be framed and the type of frame to be framed, and then the EMAC frame is written from the fragment data ram A port at the same time from B The port reading needs to input the data used for framing into the corresponding framing logic for framing.

Description

technical field [0001] The invention belongs to the technical field of network data processing, and in particular relates to a HINOC framing method, system, medium, computer equipment and application. Background technique [0002] At present: the HINOC network of coaxial cable only needs to add relevant HINOC modem equipment head-ends and terminals in the corridors and indoors, without any modification of the household cable lines, to realize the two-way transmission of various high-speed data services. The Ethernet network carries Ethernet data, while the HINOC frame is transmitted in the HINOC network. To reach the destination node through the HINOC network, the Ethernet data must be encapsulated into a HINOC frame format suitable for transmission in the HINOC network for transmission, and in The peer layer decapsulates. Through framing, multiple Ethernet frames can be packaged and encapsulated into a HINOC frame, which improves the transmission efficiency of the MAC laye...

Problems solved by technology

[0005] Through the above analysis, the existing problems and defects of the existing technology are as follows: the process of dequeuing frame query requires a very long clk cycle, and it is difficult to achieve 10G processing line speed; the time for querying the queue during cache management is relatively long; the dequeue time is relatively long ;

[0006] The difficulty of solving the above problems and defects is as follows: First, after the above analysis, the existing technology (HINOC 2.0) is difficult to achieve 10G speed due to the limitation of bit width, clock, and overall architecture; so HINOC 3.0 has made the above changes in these aspects , but the changes in bit width and architecture have brought some difficulties to framing. First, the bit width has changed from 32 bits to 128 bits. In addition, the number of subframes and the number of HINOC frames in each group are different. The framing logic is more complicated; secondly, due to the HINOC 3.0 architecture, the framing module has more interfaces for external interaction, and the design is more difficult; finally, the demand for grouping half-empty frames makes the interaction of each state machine complicated; this patent is to solve these questions
