CD-ASM: A new queuing paradigm to overcome bufferbloat effects in HetNets

摘要: Recent works have sought to improve network performance by employing Multipath Transmission Control Protocol (MPTCP) aggregate flows from heterogeneous wireless interfaces in a single connection. Although existing proposals are powerful, coupled congestion control algorithms suffer high variation path delays, bandwidth and loss rate, typical issues on networks. Such variations even higher over concurrent multipath transmissions, they enhanced presence of bufferbloat, i.e. delays caused long queues. Hence, cope with this limitation, we propose major shift the Active Queue Management (AQM) concept Stack (ASM) concept, namely Controlled Delay ASM (CD-ASM) for HetNets handle dropped packet ratio MPTCP mechanism. Differently other approaches, CD-ASM gives priority most recent packets, being promising solution. Moreover, provide detailed simulation analysis comparing CoDel DropTail schemes. Results indicate that our proposal reduces queue drops, thus diminishing impact control; keeping RTT low improving 20% goodput.
