“…Multipath congestion control. A transport layer protocol that exploits multiple paths between source and destination has been an active area of research [18], [19], [20], [21], [22], [23], [24], [25]. MPTCP [20] divides a TCP flow into multiple subflows.…”

We propose XRC, an explicit rate control algorithm that overcomes the poor performance of commonly used TCP variants in cellular networks. XRC exploits explicit feedback from the radio access network that is aware of the physical, network and transport layer information of all UEs as well as resource distribution policies for users with different traffic characteristics. XRC co-exists fairly with other XRC and non-XRC flows at the wireless and non-wireless bottlenecks while it strictly controls queuing delay within a small threshold. We implement XRC in NS-3 and examine its performance across a range of network loads and dynamics. When competing with CUBIC at a wireless bottleneck, XRC achieves a Jain's fairness index of 99.7% while providing a 3x lower median queuing delay compared to when CUBIC competes with CUBIC in the same setup.

“…This has been demonstrated in section 3.8 where both MMPTCP and MPTCP performed poorly under the incast-like conditions, mainly due to the lack of path diversity at the access layer of the network. Possible approaches to improve the MMPTCP performance under such conditions are to utilize a multi-homed network topology such as Dual-Homed FatTree (DHFT) [7], and/or equip MMPTCP with an ECN-capable multipath congestion control algorithm such as Adaptive MultiPath (AMP) [36] that performs as good as DCTCP under the incastlike conditions.…”

“…As a result, AS improves the FCT of competing short flows; if a multipath flow competes with single path flows at a highly loaded bottleneck link at the access layer (e.g. the last mile link), then it may take eight times more bandwidth than the single path flows because it can send at least 16 packets on every RTT (two packets per each subflow) whereas a single path flow can send at least two packets on every RTT (because by default the minimum window size is set to two in Linux) [35]. This condition is particularly problematic in data centres because the bandwidthdelay product is typically small (e.g.…”

Modern data centres provide large aggregate network capacity and multiple paths among servers. Traffic in data centres is very diverse; most of the data is produced by long, bandwidth hungry flows but the large majority of flows, which commonly come with stringent deadlines regarding their completion time, are short. It has been shown that TCP is not efficient for any of these types of traffic in modern data centres. MultiPath TCP (MPTCP) employs multipath data transport and is efficient for long flows but ill-suited for short flows. In this paper, we present Maximum MultiPath TCP (MMPTCP), a novel transport protocol which extends MPTCP and, compared to TCP and MPTCP, reduces short flows' completion times, while providing excellent goodput to long flows. To do so, MMPTCP runs in two phases; initially, it randomly scatters packets in the network under a single congestion window exploiting all available paths. This is beneficial to latency-sensitive flows. After a specific amount of data is sent, MMPTCP switches to a regular MultiPath TCP mode. MMPTCP is incrementally deployable in existing data centres as it does not require any modifications outside the transport layer and behaves well when competing with MPTCP flows. We also present a topology-specific extension of MMPTCP that adjusts the numbers of subflows during the second phase of the protocol based on knowledge about the location of the receiver in the data centre. We present extensive evaluation that shows that MMPTCP's design objectives are met. We have implemented MMPTCP (along with MPTCP and packet spraying) in ns-3 and evaluated our protocol in simulated FatTree topologies. We have evaluated how MMPTCP performs compared to TCP and MPTCP and how its performance is affected by transient hotspots in the network. We have also experimented with different thresholds for duplicate acknowledgements and fast retransmissions and shown that MMPTCP performs well when the size of short flows is widely ranged. Finally, we have evaluated how MMPTCP performs under conditions that result in Incast, when different congestion control algorithms are used in its second phase and when varying the overall network load.

“…J. Ye et al [30] proposed a novel sharing bottleneck detection scheme EMPTCP, which can capture the real congestion state of sharing bottleneck, thus improving network efficiency and fairness. M. Kheirkhah et al [31] proposed an adaptive multipath congestion control mechanism, which can significantly improve network fairness between multipath and single-path runoff. G. Kim et al [32] adaptively adjusted congestion window (cwnd) reduction to achieve better throughput in the non-shared bottleneck, while maintaining fairness of MPTCP flows in the shared bottleneck.…”

With the rapid development of mobile video technology and the increasing demand for online videoapplications, people have higher demands on the transmission performance and user experience ofreal-time Internet applications such as video. Multipath transmission is considered as an ideal solutionto improve video transmission performance and user experience quality in wireless networkenvironment. In recent years, the academic research on multipath transmission protocol focuses ondata scheduling, energy consumption optimization, fairness, congestion control and so on, but theresearch on network security is insufficient, especially the research on the anti-damage analysis androbustness optimization of multipath transmission. Based on a comprehensive analysis of the latestresearch trends, this paper makes a beneficial exploration of the future development of end-to-endmultipath transmission over the Internet based on Multipath TCP (MPTCP).
