“…• The inter-dependency (and processing time) between web resources reduces web performance when using multistreaming. This behaviour is not limited to TCP, for instance, Control block sharing [39] with shared bottleneck detection [40] could also result in a similar behaviour. 2 Image spriting is a technique increasingly used in web design to send a group of separate images as a single cluster.…”

This paper explores the design trade-offs required for an Internet transport protocol to effectively support web access. It identifies a set of distinct transport mechanisms and explores their use with a focus on multistreaming. The mechanisms are studied using a practical methodology that utilise the range of transport features provided by TCP and SCTP. The results demonstrate the relative benefit of key transport mechanisms and analyse how these impact web access performance. Our conclusions help identify the root causes of performance impairments and suggest appropriate choices guiding the design of a web transport protocol. Performing this analysis at the level of component transport mechanisms enables the results to be utilised in the design of new transport protocols, such as IETF QUIC.

“…We evaluated two scenarios (Ferlin et al, 2016a;Hassayoun et al, 2011), namely, subflows with and without shared links, which are denoted as NL and NSL respectively for the sake of simplicity in the remainder of this article. Fig.…”

“…Following the parameters in (Barre et al, 2011), the number of subflow N ranges from 1 to 8. For the NSL scenarios, the bandwidth is 100 Mbps and the RTTs of the subflows are set as 10 ms, 20 ms, 30 ms, 40 ms, 60 ms, 80 ms, 90 ms and 100 ms. For the SL scenario, the common link has 100 Mbps capacity and 20 ms RTT (Ferlin et al, 2016a) and the RTTs of each subflow are 20 ms, 30 ms, 40 ms, 50 ms, 60 ms, 70 ms, 80 ms and 90 ms. Unless specifically stated, the default setting of the packet loss rate is 0.…”

“…The droptail bottleneck queue was set to 1 bandwidth-delay product (BDP), which allows for 100% link utilization with a congestion control that halves its cwnd upon congestion (Ferlin et al, 2016a). The Maximal Segment Size (MSS) in our simulation is set to 1400 bytes (Ni et al, 2015), which is also the packet size at TCP layer.…”

“…The Maximal Segment Size (MSS) in our simulation is set to 1400 bytes (Ni et al, 2015), which is also the packet size at TCP layer. The socket buffer is set following the recommendation adopted in (Ferlin et al, 2016a), i.e., buffer = bandwidthi * RTTmax * 2, where N is the number of subflows, bandwidthi is the bandwidth of subflow i and RTTmax is the max RTT over all subflows. The congestion control algorithm adopts RTT-compensation as that in (Ni et al, 2015), which is used widely in MPTCP and provides more friendliness.…”

SummaryCurrent proposed congestion control algorithms for multipath transmission couple all subflows together to maintain bottleneck fairness by assuming that the subflows traverse a common bottleneck. The coupled form congestion control algorithms restrict the multipath session to gain better throughput in non‐shared bottleneck situation. The throughput of a multipath session following independent rate control is larger than the throughput achieved by coupled form congestion control algorithm. The key point is to find a method to detect whether flows share a common bottleneck. If the subflows of a multipath session are detected out traversing a common bottleneck, the sender could perform coupled congestion control algorithm to guarantee bottleneck fairness and follow independent congestion control algorithm otherwise to improve throughput. Deduced from fluid model of additive increase multiplicative decrease (AIMD) rule, the delay samples can be linearly fitted when the bottleneck link falls into congestion. A delay trend line regression (TR) method is proposed for shared bottleneck detection. The delay slopes in close proximity indicate that the flows traverse the same bottleneck in great probability. Extensive simulations are performed to validate the effectiveness of TR algorithm in shared bottleneck detection. It is further implemented in multipath QUIC Golang codebase to work in collaboration with linked increases algorithm (LIA). Results show a multipath QUIC session with two subflows can gain higher throughput in non‐shared bottleneck situation and is less aggressive in shared bottleneck cases with the implementation of shared bottleneck detection algorithm.
