     IETF ForCES Logical Function Block (LFB) Subsidiary Management
             draft-ietf-forces-lfb-subsidiary-management-01

Abstract

   Deployment experience has demonstrated the value of using the
   Forwarding and Control Element Separation (ForCES) architecture to
   manage resources other than packet forwarding.  In that spirit, the
   Forwarding Element Manager (FEM) is modelled by creating a Logical
   Functional Block (LFB) to represent its functionality.  We refer to
   this LFB as the Subsidiary Mechanism (SM) LFB.  A Control Element
   (CE) that controls a Forwarding Element's (FE) resources can also
   manage its configuration via the SM LFB.  This document introduces
   the SM LFB, an LFB that specifies the configuration parameters of an
   FE.
