Re: [6tisch] WGLC for https://www.ietf.org/id/draft-ietf-6tisch-architecture-17.txt

Hi Pascal, WG,

I drafted a summary of MSF for potential inclusion in 4.4.2.

The proposal is to:
(1) Remove MSF mention in "An optional Scheduling Function (SF) such as MSF
[I-D.ietf-6tisch-msf] is used to"
->  "An optional Scheduling Function (SF) is used to"
(2) Add the following paragraph at the end of the section:
========
As an example SF, we briefly introduce MSF [I-D.ietf-6tisch-msf].
MSF uses the rendez-vous slot from [RFC8180] for network discovery,
neighbor discovery, and any other broadcast.
For basic unicast communication with any neighbor, each node has a receive
cells at a well-known slotOffset/channelOffset, derived from a hash of
their own MAC address.
Nodes can reach any neighbor by installing a transmit (shared) cell with
slotOffset/channelOffset derived from the neighbor's MAC address.
For child-parent links, MSF continuously monitors the load to/from parents
and children.
It then uses 6P to install/remove unicast cells whenever the current
schedule appears to be under-/over- provisioned.
========

Thank you,
Simon
