Bufferbloat is a problem in a packet-switched network which can occur due to increase in the size of buffer with increase in internet traffic. This creates high latency in network which ultimately degrades the performance of the network. The usage of oversized buffer in the networks results in increasing the queuing delay. Researcher has made two types of suggestions to solve the bufferbloat problem. One is End to End (E2E) congestion control and second is deployment of Active Queue Management (AQM) techniques. This research paper focuses on comparative analysis of Active Queue Management Technique CoDel (Controlled Delay) and Congestion Control Technique LEDBAT (Low Extra Delay Background Transport) for solving bufferbloat problem. This paper compares CoDel with LEDBAT using performance metrics such as end to end delay; queuing delay and queue loss using network simulator-2 (ns-2) and the graphs are drawn using X-graph. The simulation results revealed that LEDBAT has efficiently overcome bufferbloat problem as compared to CODEL by having less end to end delay, less queuing delay and no queue loss.
