Problems solved by technology

As the protocols supported by the data network become more and more complex, the processing flow of the Ethernet chip becomes more and more complicated, and it becomes more and more difficult to debug and analyze after a problem occurs.
ASIC-based Ethernet chips have the advantages of high integration and strong data packet processing capabilities; but at the same time, they have the disadvantages of lack of debugging methods and difficult analysis of problems.
On the Ethernet switch system based on the Ethernet chip, it is impossible to track the processing process of the data packet in the chip, and it is also impossible to view the intermediate results of the data packet processing, so when there is a problem, it is difficult to debug and analyze

Embodiment Construction

[0022] Please refer to figure 1 , the software emulation ASIC forwarding system includes a hardware system and a software system. The hardware system includes an ASIC subsystem 1 and a CPU subsystem 2; the software system includes a user interface module 6, a data extraction module 4, an ASIC simulation module 5, and an ASIC driver module 3.

[0023] The ASIC subsystem realizes the processing of data packets. For data packets that cannot be processed by the ASIC subsystem, the packets can be copied to the CPU subsystem through the Ethernet interface between the ASIC subsystem and the CPU subsystem. The ASIC subsystem supports the function of forwarding the data packets received by the port to the CPU subsystem without modification.

[0024] The CPU subsystem runs system software and provides a read-write interface with the ASIC subsystem and an Ethernet interface for transmitting data packets.

[0025] The user interface module accepts user configuration, such as opening or ...

Description

technical field [0001] The present invention relates to a network communication system, in particular to a debugging and analysis system on an Ethernet switch system based on an Ethernet chip. Background technique [0002] Ethernet switches generally contain ASIC (Application specific Integrated Circuit, application specific integrated circuit) chips specially used to process data packet forwarding. General-purpose CPUs can theoretically implement any network function, but the performance is low. What ASIC technology provides is when forwarding data It is processed by a dedicated chip instead of a CPU, so the forwarding speed can be very fast, which improves the performance of the network. [0003] With the development of data communication networks, Ethernet switches begin to play an increasingly important role. In order to improve the forwarding performance of Ethernet switches, packet processing needs to be integrated into application-specific chips (ASICs). As the prot...
