“…Each of these TSNs triggers a SACK to the sender. The CMT sender uses the Cwnd Update for CMT (CUC) algorithm (Iyengar et al, 2006) to decouple a path"s cwnd evolution and data ordering. Based on SACK triggered by TSN 3 the sender uses CUC and increments C2 = 3 from 2 and decrement O2 = 1 from 2, now the available receive buffer space for new data is calculated as advertised receive window (R) = 4-total outstanding on O2 (= 2), triggers the sender to transmit two TSNs, 7 and 8 on path 2.…”

“…Adopting the value PMR = 5, whenever the value goes beyond the set threshold (PMR = 5), the sender retransmits in alternate path. Iyengar et al, (2006) (Stewart and Xie, 2002) (Iyengar et al, 2005) explored five retransmission policies for CMT and their overall analysis revealed that RTXLOSSRATE, RTX-SSTHRESH and RTX-CWND outperforms better than others. They also assumed strongly that the receiver's advertised window does not constrain the sender and since the bottleneck queues on the end-to-end paths used in CMT are independent , (Iyengar et al, 2004).…”

“…However to achieve faster yet robust failure detection, (Iyengar et al, 2006) argues for varying Path Max Retransmit (PMR) based on a network's loss rate and suggests PMR = 3 for the Internet. 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).…”

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.

“…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.

“…The Stream Control Transmission Protocol (SCTP) [19] protocol was designed with multihoming in mind and supports fail-over. Several SCTP extensions [8,12] enable hosts to use multiple paths at the same time. Although implemented in several operating systems [8], SCTP is still not widely used besides specific applications.…”

Abstract. The IETF is developing a new transport layer solution, MultiPath TCP (MPTCP), which allows to efficiently exploit several Internet paths between a pair of hosts, while presenting a single TCP connection to the application layer. From an implementation viewpoint, multiplexing flows at the transport layer raises several challenges. We first explain how this major TCP extension affects the Linux TCP/IP stack when considering the establishment of TCP connections and the transmission and reception of data over multiple paths. Then, based on our implementation of MultiPath TCP in the Linux kernel, we explain how such an implementation can be optimized to achieve high performance and report measurements showing the performance of receive buffer tuning and coupled congestion control.
