SSH over SCTP — Optimizing a Multi-Channel Protocol by Adapting It to SCTP

Secure Shell (SSH) is a multi-channel security protocol running over the Transmission Control Protocol (TCP), which offers channels for several services over a secured connection, such as remote shells and connection forwarding. In this paper we introduce a method for using SSH over the Stream Control Transmission Protocol (SCTP), a transport protocol supporting multi-homing and multi-streaming. We examine benefits of this adaptation, which can be made available to generic applications with SSH’s connection forwarding without further changes. The results also apply to other application protocols supporting a concept similar to channels.
