Problems solved by technology

[0003] However, in the case of large data traffic, there will be a problem of insufficient cache of the MAC controller
Insufficient MAC controller buffer will cause the receive buffer to overflow, and the overflow data frame will be discarded because it cannot be stored in the receive buffer, thus increasing the packet loss rate of the data frame

Abstract

The present application provides a control method and a control device. The control method is applied to a first node in an Ethernet communication system, where the first node includes multiple MAC controllers, and the control method includes: controlling the multiple MAC controllers to alternately send or receive a group of data frames. In the present application, multiple MAC controllers alternately transmit a group of data frames, so that the receiving buffers of multiple MAC controllers can alternately buffer data frames, which is equivalent to expanding the capacity of the receiving buffer, thereby reducing the probability of receiving buffer overflow. , to reduce the packet loss rate of data frames.

Description

technical field [0001] The present application relates to the technical field of Ethernet, in particular to a control method and a control device. Background technique [0002] In Ethernet, the medium access control (medium access control, MAC) controller can buffer the data frames received from the physical layer in the receiving buffer first, and then send the data frames in the receiving buffer to the Internet protocol (internet protocol, IP) layer. [0003] However, in the case of a large data flow, there will be a problem of insufficient cache of the MAC controller. Insufficient buffer of the MAC controller will cause the overflow of the receiving buffer, and the overflowed data frame will be discarded because it cannot be stored in the receiving buffer, thereby increasing the packet loss rate of the data frame. Contents of the invention [0004] Embodiments of the present application provide a control method and a control device, which can reduce the packet loss ra...
