What are 6lowpan and ROLL?
o 6lowpan and ROLL are working groups in the IETF. o 6lowpan is a working group whose charter is to develop protocols to support IPv6 running over IEEE 802.15.4 low-power radio networks. The first two documents produced by the working group are RFC4919 (a problem statement about using IPv6 with 802.15.4) and RFC4944 (which defines an adaptation layer for network layer protocols over IEEE 802.15.4 and documents how to compress and create headers for using IPv6 over 802.15.4). The working group is now tackling the areas of device and network commissioning, security and other topics to further interoperability around IP-based standards. o The ROLL working group is focused on defining routing solutions for Low power and Lossy Networks (LLNs). ROLL is currently defining the requirements for IP routing protocols that can be used in Industrial, Home, Commercial Building and Urban sensor. Additionally, the working group is developing a survey of existing IETF routing protocols to determine the
