The IESG has approved the following document: - 'ForCES Model Extension' (draft-ietf-forces-model-extension-05.txt) as Proposed Standard This document is the product of the Forwarding and Control Element Separation Working Group. The IESG contact persons are Adrian Farrel and Alia Atlas. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-forces-model-extension/ Technical Summary Forwarding and Control Element Separation (ForCES) defines an architectural framework and associated protocols to standardize information exchange between the control plane and the forwarding plane in a ForCES Network Element (ForCES NE). This memo extends the Forwarding and Control Element Separation (ForCES) model defined in RFC 5812 and updates RFC5812 to allow complex datatypes for metadata, optional default values for datatypes, optional access types for structures. It fixes an issue with Logical Functional Block (LFB) inheritance. It also introduces two new features a new event condition BecomesEqualTo and LFB properties. The changes introduced in this memo do not alter the protocol and retain backward compatibility with older LFB models. Working Group Summary The extensions are straightforward, and there was no difficulty in coming to consensus on all points described. We believe the working group is solidly behind this document. Document Quality There were earlier extensions in earlier versions of the document that were removed based on discussions in the WG for the sake of simplicity. At least one implementation has validated some of the features described in the document. The shepherd validated the sanity of the new extensions to the XML schema in section 4. AD review led to a number of changes (largely for clarity) and a significant issue which resulted in the change of the model version number.
