Subject: [Roll] last call for roll charter text.

Dear all,

Below the text for the ROLL charter as discussed in Berlin and on the mailing list.
The last additions are the milestones based on the feedback of the past months.

Many thanks for all your contributions. The text is shorter and clearer in my opinion.

Please react to (approve) the text, and review the milestone dates when they concern your work.

End of call: Saturday October 1.

Many thanks,

Peter + Ines


Charter for ROLL Working Group

Low power and Lossy Networks (LLNs ) are made up of many embedded devices with limited power, memory, and processing resources. They are interconnected by a variety of links, such as IEEE 802.15.4, Bluetooth, Low Power WiFi, wired or other low power PLC (Powerline Communication) links. LLNs are transitioning to an end-to-end IP-based solution to avoid the problem of non-interoperable networks interconnected by protocol translation gateways and proxies.

RFC7102 discusses ROLL specific aspects of LLNs, and RFC7228 provides additional terminology for constrained devices.

RFC 5548, 5673, 5826, and 5876 describe the requirements for LLNs from several application perspectives.
The Working Group has focused on routing solutions for the areas: 
connected home, building, and urban sensor networks. It has developed a Framework that takes into consideration various aspects including high reliability in the presence of time varying loss characteristics and connectivity while permitting low-power operation with very modest memory and CPU pressure in networks potentially comprising a very large number (several thousands) of nodes.

The Working Group continues to focus on routing issues for LLN and to maintain, improve and streamline the protocols developed by the working group, including RPL and MPL.

ROLL will coordinate closely with the working groups in other areas that focus on constrained networks and/or constrained nodes, such as 6lo
(Int) and lwig (Int) and CoRE (App). The working groups PiM (rtg), BIER
(rtg) and MANET (rtg) will be consulted when ROLL work can profit from their results. The Working group will align with the 6man (Int) WG when needed.

Work Items are:

- Guidance in using RFC6553, RFC6554, and IPv6-in-IPv6 encapsulation. 
The WGLC on this work will be shared with 6lo.

- Compression of  RFC6553, RFC6554, and IP headers in the 6LoWPAN adaptation layer context. (coordinated with 6lo WG).

- Additional protocol elements to reduce packet size and the amount of required routing states

- Automatic selection of MPL forwarders to reduce message replication. 
(coordinated with PiM wg)

- Data models for RPL and MPL management (coordinated with netmod and PiM wg)

- Alternative Multicast algorithm see for example Bier forwarding. 
(coordinated with PiM wg and relateds wg, e.g. BIER)

- Methods to improve or correct the current RPL behavior and the other protocols defined by the working group.

- Alternative Routing mechanism for constrained environments see for example AODV-RPL
