Comparison of Queuing Algorithms against DDoS Attack
نویسندگان
چکیده
In this paper, we are going to present the simulation results of comparison of five queuing algorithms (Drop Tail, Fair Queuing, Stochastic Fair Queuing, Deficit Round Robin and Random Early Detection) using ns-2 as simulation environment. Comparison of the queuing algorithms is based on attack-intensity. We are checking the performance of each queuing algorithm on a particular queue limit against different attack intensities. Here an attempt has been made to cover an overview of Denial of Service (DoS) attack, Distributed Denial of Service (DDoS) attack, methods of attack, DDoS attack tool kits and queuing algorithms. The results in this paper also indicate that UDP type attack traffic is more powerful as compared to TCP type attack in terms of bandwidth consumption. Keywords— DoS, DDoS, Queuing Algorithms, Attacking methods, DDoS Attack Tool Kits.

Queuing Algorithms Performance against Buffer Size and Attack Intensities in DDOS Attacks
Distributed Denial of Service (DDoS) attack is one of the biggest threats now days. This paper aims at providing the simulation results of buffer size and attack intensities effect on various queuing algorithms such as DropTail, Fair Queuing (FQ), Stochastic Fair Queuing (SFQ), Deficit Round Robin (DRR) and Random Early Detection (RED) using ns-2 as a simulation environment. The results in this...
متن کاملF-STONE: A Fast Real-Time DDOS Attack Detection Method Using an Improved Historical Memory Management
Distributed Denial of Service (DDoS) is a common attack in recent years that can deplete the bandwidth of victim nodes by flooding packets. Based on the type and quantity of traffic used for the attack and the exploited vulnerability of the target, DDoS attacks are grouped into three categories as Volumetric attacks, Protocol attacks and Application attacks. The volumetric attack, which the pro...
متن کاملSimulation and Detection of LDDoS Attacks using Queuing Algorithms
This study aims at the evaluation of queuing algorithms using NS2 simulator. The recent LDDoS attacks cause more severe damage to the TCP based applications than the traditional DDoS attacks. The congestion participation rate (CPR) approach is used for detection and prevention of LDDoS attacks. Earlier approaches can only detect the LDDoS attacks. The CPR approach using queuing management algor...
متن کاملNeural Network Based Protection of Software Defined Network Controller against Distributed Denial of Service Attacks
Software Defined Network (SDN) is a new architecture for network management and its main concept is centralizing network management in the network control level that has an overview of the network and determines the forwarding rules for switches and routers (the data level). Although this centralized control is the main advantage of SDN, it is also a single point of failure. If this main contro...
