Abstract

   This draft aims at defining the concept of capability. Capabilities
   are data that unambiguously characterize NSFs (Network Security
   Functions). Their correct definition will ease all the management
   and automation that can be. Moreover, it allows the definition of
   Interfaces to manage NSFs.

   This draft is the first trial to merge two previous existing drafts
   on NSFs capabilities [I-D.draft-baspez-i2nsf-capabilities-00] and on
   the capability interface [I-D.draft-xia-i2nsf-capability-interface-
   im-06]. Further work will be needed to homogenize all the concepts
   and incorporate the feedback that will result after its publication.
