摘要
Abstract
In wireless access networks,it proposed a lightweight delay optimization algorithm-cross-layer backpressure conges-tion control algorithm.The algorithm is a traffic source-independent,user terminal device-independent algorithm that can be deployed independently in wireless network devices.Based on queue length,air interface transmission rate,and other information,the algorithm dy-namically adjusts the receive window field of TCP acknowledgment packets(TCP ACK)to reduce end-to-end latency while reducing the to-tal buffer of wireless network devices and ensuring the total throughput capacity of wireless access points(throughput loss<5%).Compared with the traditional Cubic congestion control algorithm,this algorithm can reduce wireless access network latency by 30%to 40%in scenari-os where the access point(AP)is congested,while also reducing the buffer of AP devices by 40%and lowering the risk of packet loss.关键词
