Forwarding and Control Element Separation (ForCES)
Logical Functional Block (LFB) Subsidiary Management
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 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.
