Problems solved by technology

Since the Pause frame does not carry information about the specific congested port, using Pause frame flow control will block all packets sent through the stack port on the peer chip. Even if the destination port of the packet is not a congested port, the The port is flow-controlled by Pause frames and cannot be forwarded normally, which causes a great waste of bandwidth.
Therefore, the prior art has the technical problem of unreasonable congestion control of the switching chips in the stacked chips

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a congestion control method and a field layer device based on an industrial Internet field layer device. Background technique [0002] The Industrial Internet is the result of the convergence of global industrial systems with advanced computing, analytics, sensing technologies, and Internet connectivity. Through the connection between intelligent machines and eventually human-machine connection, combined with software and big data analysis, it can reconstruct global industry, stimulate productivity, and make the world better, faster, safer, cleaner and more economical. [0003] In the industrial Internet, the congestion management in the process of multi-switch chip stacking is mainly to prevent the peer end from sending packets to the congested port by sending a pause (Pause) frame to the peer chip through the stack port. Since the Pause frame does not carry inf...
