At IETF 69, the 6lowpan WG decided to start work on an Architecture Document. Instead of developing this as an I-D first, we decided to start development on this Wiki and only move to the I-D format later.
Specific issues that need to be addressed in the Architecture Document might include:
Network Model: How is the IPv6 network mapped to 802.15.4 concepts.
In addition, the following documents will contain architecture related text:
Bootstrapping and Commissioning (may be one or two documents, we did not decide)
Requirements will also be collected in:
Note that there also is an Application Scenarios document, which already has taken the form of an I-D (with additional contributions required).
