“…In an attempt to fulfill both MPTCP CCA design goals and implement CUBIC for MPTCP as a coupled CCA, Le et al [ 19 ] proposed MPCubic following the basic implementation principle of LIA [ 5 , 9 ]. Although they could exploit all paths simultaneously, their implementation shows aggressive fairness toward SPTCP flows, which results in a significantly low throughput in NSBs.…”

The Congestion Control Algorithm (CCA) in the Multipath Transmission Control Protocol (MPTCP) is fundamental to controlling the flow of data through multiple subflows (SF) simultaneously. The MPTCP CCA has two design goals: first, always ensure better throughput than single path TCP (SPTCP) flows, and second, collectively, MPTCP SFs going through a shared bottleneck (SB) should occupy bandwidth fairly, i.e., close to the bandwidth occupied by an SPTCP flow. Although several MPTCP CCAs exist, they primarily focus on specific scenarios and could not satisfy the design goals in diverse and dynamic scenarios. Recently, CUBIC has become a widely used CCA for SPTCP for its better compatibility with high-speed internet. CUBIC’s effective implementation in the MPTCP is expected to provide improved throughput and fairer behavior, thus satisfying the design goals. However, although the current multipath CUBIC (MPCUBIC) implementation ensures better fairness, it fails to ensure better throughput. We believe the application of same rule for SFs going through an SB and non-shared bottleneck (NSB) makes it difficult for MPCUBIC to adapt to diverse and dynamically changing network scenarios, thus resulting in poor throughput. Therefore, we present an improved version of MPCUBIC, namely bottleneck-aware MPCUBIC (BA-MPCUBIC), to resolve the throughput issue. First, we deploy an innovative bottleneck detection method that successfully differentiates between an SB and NSB based on round-trip-time, enhanced congestion notification, and packet loss. Then, we implement SPTCP CUBIC and MPCUBIC as the CCAs for SFs going through NSBs and SBs, respectively. Extensive emulation experiments demonstrate that the BA-MPCUBIC successfully detects SBs and NSBs with the highest detection accuracy and the lowest detection time compared with other approaches. Moreover, BA-MPCUBIC successfully satisfies the MPTCP design goals in the considered diverse and dynamic scenarios by ensuring both better throughput and fairness.

Feedback-Based Path Failure Detection and Buffer Blocking Protection for MPTCP

A multipath TCP (MPTCP) is a promising protocol that has been standardized by the Internet Engineering Task Force to support multipath operations in the transport layer. However, although the MPTCP can provide multiple transmission paths and aggregate the bandwidth of multiple paths, it does not consistently achieve more throughput (goodput) nor a greater connection resilience. Currently, the MPTCP is vulnerable to path failure or underperforming subflows, which cause transmission interruption or throughput (goodput) degradation. Unfortunately, there is no exact rule for declaring a path failure or preventing the usage of underperforming subflows in the MPTCP. In this paper, we propose a novel path failure detection method referred to as feedback-based path failure (FPF) detection. In addition, we propose a new decision method called buffer blocking protection (BBP) to address the underperforming subflows for the MPTCP. Measurement results indicate that the FPF detection reduces transmission interruption time by the fast path failure decision, which can prevent duplicate transmission interruption events and unnecessary retransmissions. Furthermore, the FPF detection is sufficiently robust in terms of packet loss and the delay difference between paths. The results additionally show that the BBP method prevents goodput degradation due to underperforming subflows. Consequently, the MPTCP with the BBP method can at least achieve the throughput performance of a single Transmission Control Protocol (TCP), which uses the best path regardless of the delay difference between paths.Index Terms-Multipath Transmission Control Protocol, path failure detection, buffer blocking problem.
