Dear LWIG WG, As you can see below, we have updated the LWIG TCP draft. Comments are welcome!
On the other hand, while we believe the document is starting to be quite complete, we would like to take the opportunity to ask you a few questions: 1.- With regard to the constrained TCP implementations survey in the Annex, please let us know if you would object against presence in the Annex of any of the currently covered implementations, or if you think others may need to be included. 2.- So far, we have not been able to find or receive much content for the Data size row in the summary table. A nice exception to this is RAM usage measurement results on the RIOT TCP implementation, that have been kindly provided by Simon Brummer. However, as getting similar information for the rest of implementations appears to be difficult, our proposal would be removing this row from the table (as shown in the current draft version), while keeping the "Code size" row in. RAM usage details for the RIOT TCP implementation have been included anyway as a table footnote. Would anyone object to this approach? 3.- If you are aware of specific code vulnerabilities that may arise when implementing TCP for constrained devices, please let us know. Thanks, Carles, Jon, Michael ---------------------------- Original Message ---------------------------- Subject: [Lwip] I-D Action: draft-ietf-lwig-tcp-constrained-node-networks-03.txt From: internet-dra...@ietf.org Date: Sun, June 10, 2018 10:36 am To: i-d-annou...@ietf.org Cc: lwip@ietf.org -------------------------------------------------------------------------- A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Light-Weight Implementation Guidance WG of the IETF. Title : TCP Usage Guidance in the Internet of Things (IoT) Authors : Carles Gomez Jon Crowcroft Michael Scharf Filename : draft-ietf-lwig-tcp-constrained-node-networks-03.txt Pages : 24 Date : 2018-06-10 Abstract: This document provides guidance on how to implement and use the Transmission Control Protocol (TCP) in Constrained-Node Networks (CNNs), which are a characterstic of the Internet of Things (IoT). Such environments require a lightweight TCP implementation and may not make use of optional functionality. This document explains a number of known and deployed techniques to simplify a TCP stack as well as corresponding tradeoffs. The objective is to help embedded developers with decisions on which TCP features to use.
