“…Note that we developed SCTP and SCTP-based CMT simulation modules in QualNet [13]. We also verified the correctness of our SCTP QualNet module against SCTP ns-2 module [14] before we ran our simulations (see [15] for details). This paper is organized as follows.…”

“…In addition to the differences of protocol overhead between the basic SCTP and TCP specifications, as mentioned above, we note that QualNet 4.5.1 implements RFC 1323 [38] for high performance TCP. Therefore, the TCP window scaling option, 15 is implemented together with the TCP timestamps option, which adds 12 extra 16 bytes to the TCP header of every TCP-PDU, making the TCP header 32 bytes.…”

a b s t r a c tIn prior work, a CMT protocol using SCTP multihoming (termed SCTP-based CMT) was proposed and investigated for improving application throughput. SCTP-based CMT was studied in (bottleneck-independent) wired networking scenarios with ns-2 simulations. This paper studies the TCP-friendliness of CMT in the Internet. In this paper, we surveyed historical developments of the TCP-friendliness concept and argued that the original TCPfriendliness doctrine should be extended to incorporate multihoming and SCTP-based CMT.Since CMT is based on (single-homed) SCTP, we first investigated TCP-friendliness of single-homed SCTP. We discovered that although SCTP's congestion control mechanisms were intended to be ''similar'' to TCP's, being a newer protocol, SCTP specification has some of the proposed TCP enhancements already incorporated which results in SCTP performing better than TCP. Therefore, SCTP obtains larger share of the bandwidth when competing with a TCP flavor that does not have similar enhancements. We concluded that SCTP is TCP-friendly, but achieves higher throughput than TCP, due to SCTP's better loss recovery mechanisms just as TCP-SACK and TCP-Reno perform better than TCP-Tahoe.We then investigated the TCP-friendliness of CMT. Via QualNet simulations, we found out that one two-homed CMT association has similar or worse performance (for smaller number of competing TCP flows) than the aggregated performance of two independent, single-homed SCTP associations while sharing the link with other TCP connections, for the reason that a CMT flow creates a burstier data traffic than independent SCTP flows. When compared to the aggregated performance of two-independent TCP connections, one two-homed CMT obtains a higher share of the tight link bandwidth because of better loss recovery mechanisms in CMT. In addition, sharing of ACK information makes CMT more resilient to losses. Although CMT obtains higher throughput than two independent TCP flows, CMT's AIMD-based congestion control mechanism allows other TCP flows to co-exist in the network. Therefore, we concluded that CMT is TCP-friendly, similar to two TCP-Reno flows are TCP-friendly when compared to two TCP-Tahoe flows.

“…The impact of the CMT proposal on the research community has been quite substantial, spurring a considerable amount of articles in the following years evaluating possible applications of CMT. These include applications to multihop wireless scenarios [Aydin and Shen 2009] or use of CMT during a handover process [Budzisz et al 2009;Huang et al 2009], as already mentioned in Section 5.2.4.…”

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.

“…In presence of intermittent interfering cross-traffic, authors showed that W-SCTP achieves a higher throughput than SBPP-SCTP. Aydin & Shen (2009) studied the performance of CMT SCTP over 802.11 static multihop wireless networks. They compared CMT SCTP with three different techniques: i) standard SCTP using just one path (the best one in terms of bandwidth) to send data, ii) standard SCTP using just one path (the worst one in terms of bandwidth) to send data, and iii) standard SCTP using all available paths to send data (splitting the traffic into the different available paths of the SCTP association).…”
