The IESG has received a request from the Forwarding and Control Element Separation WG (forces) to consider the following document: - 'ForCES Model Extension' <draft-ietf-forces-model-extension-03.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-08-09. This last call period is longer than usual to allow for overlap with IETF-90. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract 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). RFC5812 has defined the ForCES Model that provides a formal way to represent the capabilities, state, and configuration of forwarding elements within the context of the ForCES protocol, so that control elements (CEs) can control the FEs accordingly. More specifically, the model describes the logical functions that are present in a forwarding element (FE), what capabilities these functions support, and how these functions are or can be interconnected. RFC5812 has been around for two years and experience in its use has shown room for small extensions without a need to alter the protocol while retaining backward compatibility with older xml libraries. This document update RFC5812 and extends the model to allow complex datatypes for metadata, optional default values for datatypes, optional access types for structures and fixes an issue with LFB inheritance. The document also introduces two new features a new event condition BecomesEqualTo and LFB properties.
