WG and Chairs,

A new version of ID draft-ko-roll-mix-network-pathology has been uploaded. Please take a look and let me know of any comments you may have.

Compared to -01, -02 addresses the issues discussed at the previous meeting in Atlanta such as how a RPL network of mixed storing and non-storing mode nodes react to parent set changes (e.g., routing state management).

I would like to receive comments here on the mailing list and also request for a slot at the Orlando meeting next month for further discussions.

Thanks!

-John

> Abstract:
>   The RPL specification allows nodes running with storing or non-
>   storing modes to operate in the same network.  We describe how such a
>   mix can result in network partitioning even when there are plenty of
>   physical links available in the network.  The partitioning affects
>   both upwards (nodes to root) and downwards (root to leaf) traffic.
>   This routing pathology stems from a recommendation made in the RPL
>   specification forcing nodes with different modes of operation to join
>   the RPL network as leaf nodes only.  We propose a solution that
>   modifies RPL by mandating that all the nodes parse and interpret
>   source routing headers and storing mode nodes to sometimes act like a
>   non-storing mode root by attaching source routing headers.
