  2. Near Term Prototyping • MIB Development • Rapid development exposes data and metrics from reference DTN implementations • ION/DTN2/others • Based on Existing IP Network Management Protocols • SNMPv3, Netconf • Testing on IP-based networks with SNMP Gateways

  3. Current Successes • Performance data from DTN Implementations identified • MIBs identified for DTN • Initially extracted from DTN2 implementations, provided by BBN and maintained by GRC. • Ohio University inspects ION shared memory to construct a MIB • ION NM status queried via SNMP (via open standards visualizations such as openNMS) • Modifying terrestrial implementations to work over high latency • Netconf • Work ongoing within MANET research group to modify netconf to support verify-commit commands to roll-back bad configuration changes to remote nodes. • Proposed CNMP protocol for extending Netconf to support rudimentary sanity checks on configuration changes. • SNMP gateways • Provide visualization into status via report-to EIDs to an SNMP gateway.

  4. Roadmap • Abstract SNMP Data Model • MIBs collectively implement a data store of local data collection • The SNMP agent is a local data manager for its data store • The SNMP agent is also a data aggregator to the network • Incremental Improvement of Existing Technology • Extend Netconf to work absent sessions • Provide subnet gateways for interfacing with SNMP systems • Introduce Data Aggregation • Collect high rate data locally, publish fused/trended/conditioned data remotely. • Requires some configuration at each node to define transformations • Eases bandwidth requirements on links • Different NM data over time, or in response to conditions • Report MIB : configurable aggregation of fused local data

  5. Near-Term Prototyping
