Constraint-based proactive scheduling for MPTCP in wireless networks

Reducing transport latency for short flows with multipath TCP

“…However, as the RTT of the second subflow increases, the performance of MPTCP is getting worse. This phenomenon is also reported by the prior research (Ferlin et al, 2016b;Oh and Lee, 2015;Yedugundla et al, 2016). Fig.…”

“…Then packets are allocated to the other subflows. Although this policy works better than the Round-Robin policy in many cases, recent research suggested that RTT can result in suboptimal resource utilization, particularly when the paths are dissimilar (Raiciu et al, 2012;Chen et al, 2013;Oh and Lee, 2015). This heterogeneity results in packet reordering, which leads to Head-of-Line (HoL) blocking, and subsequently increases out-of-order (OFO) buffer at the receiver side and ultimately reduces the Goodput.…”

“…This heterogeneity results in packet reordering, which leads to Head-of-Line (HoL) blocking, and subsequently increases out-of-order (OFO) buffer at the receiver side and ultimately reduces the Goodput. Various enhanced scheduling schemes, like BLEST (Blocking Estimation-based MPTCP Scheduler) (Ferlin et al, 2016b), CP scheduling (Constraint-based proactive scheduling) (Oh and Lee, 2015), DAPS (Delay-Aware Packet Scheduler) (Kuhn et al, 2014;Sarwar et al, 2013), OTIAS (Out-of-order Transmission for Inorder Arrival Scheduler) (Yang et al, 2014), HSR (Highest Sending Rate), LWS (Largest Window Space) and LTS (Lowest Time/Space) (Kimura et al, 2017) have been proposed to fully utilize all paths.…”

Implementação Inicial da RFC 6897 para Auxílio no Tratamento de Fluxos Elefantes

“…Desde 2013, todos os tablets e smartphones da Apple utilizam o MPTCP na aplicação de reconhecimento de voz chamada Siri, explorando um dos aspectos do protocolo cujo objetivoé manter a conectividade quando há falha em um dos caminhos possíveis na rede. Em julho de 2015, a maior companhia de telefonia sul-coreana, a Korean Telecom em parceria com a Samsung anunciou a implantação em escala comercial do protocolo MPTCP em diversos smartphones equipados com Android, combinando as interfaces LTE com wifi disponíveis, aumentando significativamente o ganho na taxa de utilização de banda desses dispositivos [Oh and Lee 2015].…”

Experimental performance analysis of multipath TCP path characteristics in streaming UHD HEVC-dash over wireless networks

“…This paper extends their research by considering the effect of MPTCP in streaming video services in a mobile environment using wireless network. In [23], a proposed packet scheduling algorithm for MPTCP in wireless network using simulation with Network Simulator 3 (NS3) was employed to analyze the efficiency of MPTCP. Though this finding offer insight into the behaviour of MPTCP in wireless situation, it didn't evaluate MPTCP performance in a mobile environment using real measurements as used in this research.…”
