Beneficial Transparent Deployment of SCTP: The Missing Pieces
The Internet-wide deployment of new transport protocols such as the Stream Control Transmission Protocol (SCTP) is a difficult matter. While SCTP could be beneficial in many cases, it is still a major challenge to enable applications to use the new protocol. The authors believe that its deployment could be significantly accelerated by introducing an intermediate step: transparent usage below TCP, such that TCP-based applications automatically obtain a benefit. They have implemented a Linux based TCP-SCTP mapping tool that exploits SCTP's multi-streaming feature, and carried out measurements which show that such an approach can significantly improve the performance of TCP applications.
