“…This paper combines and extends results published by the authors in three incremental conference publications [5][6][7], thereby documenting the complete development of this research. Section 2 demonstrates the problem with SCTPs current retransmission policy (AllRtxAlt) by comparing it to an alternative policy, AllRtxSame (All Retransmissions to Same).…”

“…To do so, we introduce the FrSameRtoAlt policy-a hybrid of AllRtxAlt and AllRtxSame. FrSameRtoAlt sends (a) fast retransmissions to the same destination as their original transmissions, and (b) timeout retransmissions to an alternate destination [7]. Since timeouts tend to occur more often at higher loss rates, this policy increases the use of the alternate path as the primary path's loss rate increases.…”

Retransmission policies for multihomed transport protocols

We evaluate three retransmission policies for transport protocols that support multihoming (e.g. SCTP). The policies dictate whether retransmissions are sent to the same peer IP address as the original transmission, or sent to an alternate peer IP address. Each policy presents tradeoffs based on the paths' bandwidth, delay, loss rate, and IP destination reachability. We find that sending all retransmissions to an alternate peer IP address is useful when the primary IP address becomes unreachable, but often degrades performance in non-failure scenarios. On the other hand, sending all retransmissions to the same peer IP address as the original transmission reverses the tradeoffs. We balance the tradeoffs by proposing a hybrid policy that sends fast retransmissions to the same peer IP address as the original transmission, and sends timeout retransmissions to an alternate peer IP address. We show that even with extensions which we proposed to improve the policies' performance, the hybrid policy is the best performing policy in failure and non-failure scenarios. q

“…The retransmission policy, that is, on which path the retransmissions should be sent and under which constraints, has been extensively studied by Caro et al [2003aCaro et al [ , 2003bCaro et al [ , 2004bCaro et al [ , 2006b]. Three basic retransmission policies were evaluated: send all retransmissions on the alternate path, send all retransmissions on the primary path, and a hybrid policy that sends fast retransmissions on the primary path and timeout retransmissions on the alternate path.…”

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.

“…The multi-homing feature allows the two endpoints to establish an association using multiple IP addresses. This feature can be used by SCTP endpoints to improve the efficiency of data transmissions by performing the primary path change in the face of a path failure [4][5][6], or by allowing a sender to transmit data to a multi-homed receiver through different destination addresses simultaneously [7][8][9][10].…”

Partial CRC Checksum of SCTP for Error Control over Wireless Networks

In the Stream Control Transmission Protocol (SCTP), when a portion of a packet is corrupted, the entire packet will be discarded at the receiver side. This may result in degradation of the throughput of SCTP over wireless networks with a high bit error rate. This paper proposes a new error control scheme of SCTP using a partial Cyclic Redundancy Check (CRC) checksum to enhance the throughput performance, in which a new 'checksum chunk' is introduced to effectively identify any corruptions of data chunks contained in the SCTP packet. In the proposed scheme, an SCTP data packet can carry one or more data chunks depending on the channel condition, and the newly defined 'checksum' chunk will contain the partial CRC checksums of the individual data chunks and/or the base header of the packet. By referring to these partial checksums, the receiver can discard only the corrupted data chunks, whereas the other available data chunks can be recovered. Simulation results show that the proposed scheme significantly provides better performance than the standard SCTP in the wireless networks.
