NETCONF details

NETCONF

NETCONF is an IETF defined configuration management protocol to “install, manipulate, and delete the configuration of network devices”. NETCONF operations are conveyed in a Remote Procedure Call (RPC) layer using XML encoding to provide a basic set of operations to edit and query configurations on a network device.

  • next generation Internet services configuration and management
  • transactions allow all or nothing deployment of services
  • configuration and operational data are identified separately
  • has sets of configuration rather than sequences making backup and restore easier and more robust
  • multiple configurations (running, startup, candidate)
  • filtering allowing retrieval of only the data requested
  • uses standard security and encryption mechanisms
  • can augment or replace legacy CLI & SNMP
  • decreases:
    • downtime
    • service degradation
    • expensive failure analysis

YumaWorks’ YumaPro SDK implements the NETCONF standard fully, including optional requirements.

Key features of YumaPro SDK’s NETCONF implementation:

  • high performance
  • keeps current with evolving standard’s features
  • configuration can be tested and validated
  • uses standard security and access control models
  • event notifications
