Hi All, We just submitted a new revision of the PASA main specs document. As I mentioned during my talk back in London, there were a couple of points that needed some refinements. Hence this revision of the document.
Beyond the usual text refinement and typo hunting, the main changes are: - External communication: Since every parent is the default route of its children it is actually very easy to forward the packet to a destination outside the PASA domain, just forward to the parent until the packet reaches the root. The latter will uncompress the IPv6 header for further forwarding. There is not even the need of using the PASA routing header. You can see the details in what is now Section 7.2. - PASA address allocation: Address allocation is now based on RFC 8505, extending the use of EARO (Extended Address Registration Option). In this way there is no need to create new ICMP messages (this was the previous solution).Details can be found in Section 8. This completes the overall review of the document to address the feedback received during call for adoption and make the proposal more integrated in the 6lo protocol stack. Any further feedback is more than welcome.

This document LI> focuses on carrying IP packets across an LLN (Low power and Lossy LI> Network), in which the topology is static, the location of the nodes LI> is fixed, and the connection between the nodes is also rather stable. LI> This specifications describes the PASA architecture, along with PASA LI> address allocation, forwarding mechanism, header format design, LI> including length-variable fields, and IPv6 interconnection support.
