Summary

3. Introduction common Network Information System (cNIS)
Unified repository of relevant network information
To avoid effort duplication, replication of data and inconsistency
Northbound interfaces (use NML instead)
Information about a single domain only
One self-managed instance of cNIS per domain
cNIS v1 deployed Sep
Automatic IP network discovery

4. Schema cNIS schema is a RDBMS schema not XML
Flexible design, with a technology-agnostic core such that support for new protocols can be added easily
Time information kept, so that past and future topologies can be accessed
Schema Task Force established
Reviewing IP, Ethernet and SDH schema
Work on OTN, Fibre schema
UML data model in version 0.17 – work in progress

5. Current Status
Four Bug fixes and feature enhancement releases since v1
perfSONAR NMWG Topology interface implemented
Tested with DFNs CNM tool
perfSONAR echo request/response interface implemented
A plugin Network Discovery Framework
Hungarnet working on Ethernet discovery (Net Spotter)
Tested on Renater testbed as well as GÉANT2, GARR and LRZ networks
Trials with other perfSONAR pilot NRENs delayed

6. Future Plans cNIS v1.1 to be released in March 2008
Further refine schema
Integrate with eduGAIN (GIdP), Lookup service
Automated discovery for Ethernet, SDH and OTH layer
Working with Hungarnet (NetSpotter)
Support for initial deployments
Transition to Service
Provide input to, and in future adopt, OGF NML-WG

7. Summary cNIS a unified repository of network information
RDBMS schema modelled in UML
Task force working on schema refinement
cNIS v1 released Sep 2007, v1.1 coming soon
