Hi,

I just discovered this mailing list. Some aspects I have in mind about
the topic of managing constrained devices and networks:

- Do we actually manage single devices or whole networks (or groups of
devices)? At least in MANETs, it may be of equal interest to monitor
(and manage) the performance of a whole network, rather than just a
single router.
- Should we support a distributed approach or a enforce a centralized
NMS? (or support both modes of operation?)
- Which transport protocols do we want to use? TCP/UDP or something like COAP?
- Do we need efficient, reliable multicast (like NORM, but
lightweight) to distribute control traffic more efficiently?
- Can we provide sufficient levels of security without putting too
much burden on constrained devices? Which authentication modes do we
need?
- Should there be a proxy functionality like RMON (or something like
the currently developed REPORT-MIB in MANET), in order to record
performance related values locally and then send to a NMS later?
- Will there be a mapping to existing management protocols like SNMP
for border gateways?
- Is there any assumption for this work about the reliability of the
channel, the kind of the link layer (e.g., wireless/wired), mobility
etc? Or is the only assumption that the devices are "constrained" (in
terms of memory? CPU? network connection?)

Best
Ulrich




[Coma] Subject: New Non-WG Mailing List: coma -- Management of
Constrained Networks and Devices

    List-id: Management of Constrained Networks and Devices <coma.ietf.org>

A new IETF non-working group email list has been created.

List address: coma at ietf.org
Archive:  http://www.ietf.org/mail-archive/web/coma/
To subscribe:  https://www.ietf.org/mailman/listinfo/coma

Purpose: This list is for the discussion related to the management of
constrained networks and devices. The IETF so far has not developed
specific technologies for the management of constrained networks.
There is a need to
understand the requirements for the management of such a constrained
network and its devices.

For additional information, please contact the list administrators.
