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
