6lowpan Working Group 62 nd IETF, Minneapolis WG Chair: Geoff Mulligan, Invensys Mailing List:

Housekeeping Anyone willing to take notes (a couple)? Jabber scribes (volunteers)? When on microphone, please state name for audio audience.

Agenda ● Agenda Bashing – 5m ● Problem Statement – 25m ● IPv6 over 15.4 – 30m ● Routing/Meshing Discussion – 20m ● Implementation Considerations – 20m ● Gap Discussion – 20m

Charter Produce "Problems Statement, Assumptions and Goals for IPv6 for LoWPANs" (draft-ietf-lowpan-goals-assumptions-xx.txt) to define the problem statement and goals of 6lowpan networks. Produce "Transmission of IPv6 Packets over IEEE WPAN Networks" (draft-ietf-lowpan-ipv6-over xx.txt) to define the basic packet formats and sub-IP adaptation layer for transmission of IPv6 packets over IEEE This includes framing, adaptation, header compression and address generation. Furthermore, IEEE devices are expected to be deployed in mesh topologies. As such, the working group may also work on an informational document to show how to apply an existing MANET protocol to LoWPANs (e.g., AODV, OLSR, DYMO, etc).

Problem Statement Nandakishore Kushalnagar Intel

IPv6 over IEEE Gabriel Montenegro Sun Microsystems

Routing Discussion

Routing Issues ● Routing vs Meshing ● Super or Sub IP ● Reactive/Proactive ● RAM vs Bandwidth ● Size of Networks ● A Mesh of Nets (A Net of Meshes)

Implementation Considerations ● Embedded systems ● Code Size ● Energy ● Just enough security (what layer) ● What services (security, service discovery,...) ● Transport layer ● Compatibility

Gap Discussion
