Abstract

The present invention provides a data transmission buffer queue allocation method and device, wherein the method includes: according to the congestion notification message CNM generated when the congestion occurs, determining the forward port for sending the congestion control flow CCF to the congestion point where the congestion occurs; according to the CNM A predetermined number of data transmission buffer queues are allocated to the CCF of the forward port, which solves the problem of high packet loss rate at the congestion point in the related art, and reduces the packet loss rate of the congestion point.

Description

Data transmission buffer queue allocation method and device technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for allocating a data transmission buffer queue. Background technique In the Ethernet three-layer protocol network, the Transport Control Protocol (Transport Control Protocol, referred to as TCP) and User Datagram Protocol (UDP for short) are widely used as standard transmission protocols. Wide application. Among them, the TCP protocol adopts a congestion control mechanism to ensure the reliable transmission of data packets, but because of various factors The network packet loss is regarded as network congestion, and its transmission efficiency is low; while the UDP protocol is based on the connectionless network protocol packet transmission. The transmission reliability is low. [0003] In 2010, the IEEE standards organization released a series of related standards for lossless Eth...
