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 modeled 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 class@ an LFB class that specifies the configuration parameters of an FE. The configuration parameters include new LFB class loading and CE associations; they also provide manipulation of debug mechanisms along with a general purpose attribute definition to describe configuration information.
