The Stream Control Transmission Protocol (SCTP) is a new Internet standards track transport layer protocol. SCTP was designed to transport PSTN signaling messages over IP networks, but SCTP is also capable of serving as a generalized transport protocol. As such, SCTP provides an alternative to the traditional transport protocols, TCP and UDP, that may be better able to satisfy the requirements ...

With its new features such as multi-homing, multi-streaming, and enhanced security, the Stream Control Transmission Protocol (SCTP) has become a promising candidate to join UDP and TCP as a general-purpose transport layer protocol. Multiple streams in an SCTP association provide an aggregation mechanism to accommodate heterogeneous objects, which belong to the same application but may require d...

In a heterogeneous wireless environment, mobility particularly vertical handover between WiFi and cellular data service has to be supported. The support for multihoming feature makes Stream Control Transmission Protocol (SCTP) become a promising transport layer-based handover scheme for end users. Although the benefits of applying SCTP for multimedia delivery and handover have been proved to be...

We identify overheads associated with FTP, attributed to separate TCP connections for data and control, non-persistence of the data connections, and the sequential nature of command exchanges. We argue that solutions to avoid these overheads using TCP place an undue burden on the application. Instead we propose modifying FTP to use SCTP and its multistreaming service. FTP over SCTP avoids the i...

This paper provides an exhaustive performance analysis by simulation of the SCTP transfer protocol in WiMAX and Wi-Fi networks. We provide also a comparison of SCTP with both transfer protocols UDP for VoIP applications and TCP for FTP sessions, as SCTP can support these two types (elastic and non-elastic) of traffic. Finally, we study how SCTP performs when a mobile is multi-homed, i.e. connec...

The Stream Control Transmission Protocol (SCTP) is a new Internet standards track transport layer protocol. SCTP was originally designed to transport PSTN signaling messages over IP networks, but is also capable of serving as a general purpose transport protocol. As such, SCTP provides an alternative that may be better able to satisfy the requirements of future battlefield networks than the tra...

This paper uses simulation studies to explore the behaviour of SCTP congestion control. Several possible variants of SCTP congestion control are identified and each is compared with the behaviour of Reno TCP, a well-known TCP variant. We identify three flaws in the current SCTP congestion control mechanisms. 1. Efficient recovery after a packet loss is only possible if SCTP generates the option...

SCTP (Stream Control Transmission Protocol) provides interesting features, as multihoming and multistreaming, to enhance information transport performances over air interfaces. Additional extensions have been proposed to adapt SCTP to wireless context (mSCTP: mobile SCTP). However, published approaches do not take into account channel state information during handover processes. The present wor...

Stream Control Transmission Protocol (SCTP) specifications utilize the multiple paths capabilities between the sender and receiver for retransmission of lost data chunks and as a backup in case of primary path failure. Under normal conditions, all data chunks are sent on the primary path chosen by the SCTP user during the transport connection initiation. In this paper, we address in detail vari...
