摘要: Recently, low latency has become one of the most critical requirements in Wi-Fi networks (e.g., for Internet access). Many factors and events such as bufferbloat, which unexpectedly happen, can affect delay networks. Hence, requirement leads to essential a management mechanism, 1) correctly detect negative behavior latency; 2) adjust network settings adaptively. In this paper, we introduce solution two mentioned issues, uses emerging Software Defined Networking (SDN) technology. Our SDN-based method guarantee predetermined value by taking advantage SDN. More specifics, monitor fluctuation on an SDN controller. We then deploy task queue adjustment when exceeds one. have developed evaluated our using mininet-wifi emulator POX The results show that maintain guaranteed level packet transmissions without significant effects performance.
