Abstract

The ForCES model [RFC5812] presents a formal way to define Forwarding Element (FE) Logical Functional Blocks (LFBs) using the eXtensible Markup Language (XML). [RFC5812] was published several years before this document, and experience with its use has demonstrated the need to add new modeling concepts and change existing ones.

    Forwarding and Control Element Separation (ForCES) Model Extension

Abstract

   This memo extends the Forwarding and Control Element Separation    (ForCES) model defined in RFC 5812 and updates that RFC to allow    complex data types for metadata, optional default values for data    types, and optional access types for structures.  It also fixes an    issue with Logical Functional Block (LFB) inheritance and introduces    two new features: a new event condition called eventBecomesEqualTo    and LFB properties.  The changes introduced in this memo do not alter    the protocol and retain backward compatibility with older LFB models.
