With the growth of internet, the user's requirements in terms of scale, functionality of network and performance of internet also increases. It becomes very important to guarantee the efficiency, stability and performance of a given network as per the user's requirements. There are many management techniques that need to be taken care of, so as to ensure network stability. These include queue management, queue scheduling, congestion control etc. But the most fundamental and foremost amongst these is congestion control, as it's not possible to ensure Quality of Service (QoS) with a congested network. To avoid congestion, many algorithms are available; the most basic of them is Random Early Detection (RED). This paper implements RED and its enhancement Adaptive RED (ARED) in NS-3 simulator and comparative analysis of both the algorithms has been carried out.

Abstract


With the growth of internet, the user's requirements in terms of scale, functionality of network and performance of internet also increases. It becomes very important to guarantee the efficiency, stability and performance of a given network as per the user's requirements. There are many management techniques that need to be taken care of, so as to ensure network stability. These include queue management, queue scheduling, congestion control etc. But the most fundamental and foremost amongst these is congestion control, as it's not possible to ensure Quality of Service (QoS) with a congested network. To avoid congestion, many algorithms are available; the most basic of them is Random Early Detection (RED). This paper implements RED and its enhancement Adaptive RED (ARED) in NS-3 simulator and comparative analysis of both the algorithms has been carried out.
