SNMP is widely used for management and monitoring of IP networks and
it's deployment would also ensure re-usability of the existing
established network management tools.
A possible investigation to determine the usability of SNMPv3 (or an
appropriate adaptation of it) is needed.
Moreover, SNMP is deployable in 6LoWPANs and three basic deployment
models may be possible for SNMP given 6LoWPANs.
1. Lightweight E2E
The SNMP manager talks SNMPv3 end-to-end to the nodes. (Adaptations
may be needed by specifying suitable deployment parameters through an
Applicability Statement).
Manager <-------------------------------------> 6LoWPAN nodes
SNMPv3
2. Proxy Model
The SNMP manager talks SNMPv3 to an SNMP proxy residing on the 6LoWPAN
Gateway (or a proxy server). Existing management tools (as long as
they are proxy aware) can be reused. In this model, 6LoWPAN adaptation
layer may not be strictly needed since SNMP can run over directly over
IEEE 802 networks [RFC4789].
Manager <--------> SNMP Proxy <--------------> 6LoWPAN nodes
SNMPv3 (6LoWPAN Gateway) SNMPv3
3. SNMP with Sub-Agent Protocols
The SNMP manager talks SNMPv3 to an extensible SNMP agent residing on
the 6LoWPAN router which uses a subagent protocol (e.g. a 6LoWPAN
enhanced version of AgentX) to populate its MIB. In this scenario,
6LoWPAN adaptation layer may not actually be needed since such
subagent protocol can also run directly over 802.15.4. However, the
current standard subagent protocol has to be optimized for 6LoWPAN.
Manager <-------> SNMP Agent <-----------------> 6LoWPAN nodes
SNMPv3 (6LoWPAN Gateway) SubAgent Protocol
Network Management in my opinion should certainly be considered as a
possible charter item once the group recharters.
