“…Permanent receiver buffer blocking in CMT-PF: Natarajan et al (2009), claims for mitigating the failureinduced receiver buffer (rbuf) blocking problem by introducing a new "" Potentially-Failed" (CMT-PF) and improved the performance of data transmission comparing with receiver buffer blocking in CMT. When using three paths their failure induced rbuf problem depicted through their experiment resulted permanent receiver blocking, which is explained via time line diagram of Fig.…”

“…Also, a tradeoff exists on deciding the value of PMR-a lower value reduces rbuf blocking but increases the chances of spurious failure detection, whereas a higher PMR increases rbuf blocking and reduces spurious failure detection in a wide range of environments (Natarajan et al, 2009). Trong et al (2010) achieved good throughput for single radio multi-channel multipath wireless mesh networks, by utilizing scheduling (Gao et al, 2004) availability with only one wireless card i.e., in Single path, therefore about concurrent transfer in multipath is not discussed.…”

Problem statement:In multihomed host, if data transfer starts using CMT, unaware of paths status causes delay in data transfer or packet loss due to path failure. Transmission Path (one or more paths) failures result in out-of-order data delivery causing receiver buffer blocking and preventing sender from transmitting further data. Approach: Multipath State Aware Concurrent Multipath Transfer using Redundant Transfer (MSACMT-RT), status of multipath is determined, initially and periodically before transmission. Data transfer begins immediately after determining the path status, for a particular interval of time and later transfers with CMT only for predefined period. Results: We discuss MSACMT-RT performance in symmetric paths with the constrained receiver buffer (rbuf) value of 128 and 256KB's. Our simulation result shows Percentage of throughput Increase between 5-15% for transfer of 20 and 40MB file sizes. Conclusion: By using MSACMT-RT we infer that our algorithm outperforms on par or better but never worse than Concurrent Multipath Transfer Potentially Failed (CMT-PF). MSACMT-RT mechanism in alternate paths increases the throughput during aggressive failures and Non-failure scenarios. Larger the file sizes of file transfer, greater the degree of throughput with less transfer time is achieved.

“…CMT-PF marks the path that has experienced a failure (a single timeout) as potentially failed and stops transmitting data on such a path until a positive heartbeat probe is returned. An extensive evaluation of CMT-PF presented in Natarajan et al [2009] shows that the proposed solution performs better or similar but never worse than CMT. The CMT-PF proposal has been conceived for lossy network scenarios, although not particularly designed with wireless networks in mind, thus facilitating the idea of applying CMT to also improve transport layer handover.…”

A taxonomy and survey of SCTP research

The Stream Control Transmission Protocol (SCTP) is a relatively recent general-purpose transport layer protocol for IP networks that has been introduced as a complement to the well-established TCP and UDP transport protocols. Although initially conceived for the transport of PSTN signaling messages over IP networks, the introduction of key features in SCTP, such as multihoming and multistreaming, has spurred considerable research interest surrounding SCTP and its applicability to different networking scenarios. This article aims to provide a detailed survey of one of these new features-multihoming-which, as it is shown, is the subject of evaluation in more than half of all published SCTP-related articles. To this end, the article first summarizes and organizes SCTP-related research conducted so far by developing a four-dimensional taxonomy reflecting the (1) protocol feature examined, (2) application area, (3) network environment, and (4) study approach. Over 430 SCTP-related publications have been analyzed and classified according to the proposed taxonomy. As a result, a clear perspective on this research area in the decade since the first protocol standardization in 2000 is given, covering both current and future research trends. On continuation, a detailed survey of the SCTP multihoming feature is provided, examining possible applications of multihoming, such as robustness, handover support, and loadsharing.

“…To address this problem, this document specifies a quick failover algorithm called "SCTP-PF" based on the introduction of a new Potentially Failed (PF) path state in SCTP path management. The performance deficiencies of the failover operation described in RFC 4960, and the improvements obtainable from the introduction of a PF state in SCTP, were proposed and documented in [NATARAJAN09] for Concurrent Multipath Transfer SCTP [IYENGAR06].…”

The Stream Control Transmission Protocol (SCTP) supports multihoming. However, when the failover operation specified in RFC 4960 is followed, there can be significant delay and performance degradation in the data transfer path failover. This document specifies a quick failover algorithm and introduces the SCTP Potentially Failed (SCTP-PF) destination state in SCTP Path Management.This document also specifies a dormant state operation of SCTP that is required to be followed by an SCTP-PF implementation, but it may equally well be applied by a standard SCTP implementation, as described in RFC 4960.
