Hello Tengfei

Architecturally speaking, MSF right now is used to allocate cells in the L3 
bundle with a parent.

“

Layer-2 vs. Layer-3 bundle:
Bundles are associated for either Layer-2 (switching) or Layer-3 (routing) 
forwarding operations. A pair of Layer-3 bundles (one for each direction) maps 
to an IP Link with a neighbor, whereas a set of Layer-2 bundles (of an 
"arbitrary" cardinality and direction) corresponds to the relation of one or 
more incoming bundle(s) from the previous-hop neighbor(s) with one or more 
outgoing bundle(s) to the next-hop neighbor(s) along a Track as part of the 
switching role, which may include replication and elimination


“

So even if it is operating under IP, it is working for IP. Even the notion that 
the neighbor is a parent is an IP layer consideration. So MSF is IPv6-aware.
IOW the IP layer passes an IP packet to the lower layer (6top), and 6top needs 
to assign the packet to a bundle. Once that is done, if the bundle is managed 
by MSF, then MSF observes the transmission. Same goes for incoming traffic.

Do you want me to provide the sentences or do you feel safe about putting your 
own words?

Subject: [6tisch] MSF adapts to traffic only for secured packets

Hi All,

For securing the MSF, (comments from minimal security, thanks for the input!)

In the next version of MSF, we need to add sentence saying MSF only adapts the 
traffic which is secured, practically by checking the DSCP value set with zero 
or no, which is in IPv6 header.

In other hands, MSF is a link layer protocol, it doesn't suppose to know the 
frame is a IPv6 packet or not. no need to say a field value.

I would like to have some suggestions/comments on this issue.
Does anyone know other way to make the SF not adapt to unsecured traffic 
without knowing upper layer field?

Thanks!
Tengfei
