Ideas for a Next Generation of the Stream Control Transmission Protocol
(SCTP)
draft-dreibholz-tsvwg-sctp-nextgen-ideas-12
Abstract
This document collects some ideas for a next generation of the Stream
Control Transmission Protocol (SCTP) for further discussion. It is a
result of lessons learned from more than one decade of SCTP
deployment.

1. Introduction
1.1. Abbreviations
o SCTP: Stream Control Transmission Protocol
1.2. Stream Control Transmission Protocol
The Stream Control Transmission Protocol (SCTP) has been defined as
RFCs in [1], [2], [3], [4], [5], [6], [7], [8], [10], [11], [12],
[13], [14], [15]. There is also a detailed introduction provided by
[22] as well as lots of further information material on [19]. SCTP
is therefore not introduced in more detail here.
1.3. Scope
The scope of this document is to collect some ideas of what to
update/change for a next generation of the SCTP protocol. It is a
result of lessons learned from more than one decade of SCTP
deployment (see also [22]) as well as ongoing discussions on applying
SCTP for WebRTC Data Channels (as introduced in more detail in [18]).
2. What to Change in the Next Generation of SCTP?
o Make useful extensions part of the next generation core protocol
itself (that is, make their implementation a MUST):
* Partial Reliablility ([4])
* Chunk Authentication ([6])

Internet-Draft SCTP Next Generation Ideas September 2020
* Partial Reliablility ([8])
* Stream Reconfiguration ([13])
* SACK Immediately ([15])
o Consider additional features as part of the next generation core
protocol:
* Non-Renegable Selective Acknowledgments (NR-SACK) ([24])
* Concurrent Multi-Path Transfer for SCTP (CMT-SCTP) ([16])
o Chunk Authentication provides integrity but not confidentiality.
There could be a feature for encryption as well, for example like
[17]. Having encryption directly included inside the core
