Personally, I do not k now what was wrong with " Ethernet-based
subscriber access networks" to begin with. Perhaps someone can explain it
to me what is wrong with this term - the way I read it, it is anything
that runs Ethernet, irrespective of the media underneath; and if we run
Ethernet, we can run this new management protocol of ours. The " the IEEE
802 suite" term is not any clearer and I would argue - it is way more
vague and ill-defined.
The " ability to transit MAC-bridges" is inherent to any L2 frame unless
it is explicitly link local.
I also do not know " in a single IEEE 802 MAC domain" is a
well-established term and what it is intended to mean. For link-local
protocols, this would be just link itself. I believe what you mean in
here is L2 broadcast domain, i.e., as far as any broadcast L2 frame
would reach. This is the term I saw used before

Subject: PAR Modification for IEEE 1904.2
Colleagues,
During the 1 August 2018 meeting we discussed the need to modify the
scope of the PAR for IEEE 1904.2.
There was consensus that
1. encryption should be removed from the scope, 2. "Ethernet-based”
should be clarified, 3. the type of devices to be managed needs to be
expanded beyond “CPE”
4. “Multi-hop” should be clarified to limit the scope to Layer-2
The current PAR Scope reads as follows:
This standard describes a management channel for customer-premises
equipment (CPE) connected to Ethernet-based subscriber access networks.
The key characteristics of the specified management channel are:
- Multi-hop capabilities to allow management of various CPE devices
located behind an Optical Network Unit (ONU), a Coaxial Network Unit
(CNU), a Residential Gateway (RGW), etc.
- Extensibility to accommodate new management protocols and/or new types
of CPE devices.
- Broadcast/multicast capabilities to allow simultaneous (synchronized)
configuration of multiple devices.
- Encryption capabilities to ensure secure access to managed CPE devices
by the network operators.
The standard describes the message format as well as processing
operations and forwarding rules at the intermediate nodes.
I propose the following as an updated scope:
This standard describes a management channel for devices used in
subscriber access networks that use protocols in the IEEE 802 suite. The
key characteristics of the management channel are:
- The ability to transit MAC-bridges in a single IEEE 802 MAC domain to
allow management of devices using protocols that would not normally be
forwarded.
- Extensibility to accommodate new management protocols and new types of
devices.
- The ability to simultaneously send messages to multiple stations using
broadcast or multicast functions.
This standard describes the message format as well as processing
operations of stations and MAC-bridges.
Please reply with comments and suggested edits.
