The IESG has received a request from the Common Control and Measurement Plane WG (ccamp) to consider the following document: - 'Label Switched Path (LSP) Data Path Delay Metrics in Generalized MPLS/ MPLS-TE Networks' <draft-ietf-ccamp-dpm-06.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 2012-08-15. 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. The IETF last call has been extended because it spans the IETF-84 meeting. Abstract When setting up a label switched path (LSP) in Generalized MPLS and MPLS/TE networks, the completion of the signaling process does not necessarily mean that the cross connection along the LSP have been programmed accordingly and in a timely manner. Meanwhile, the completion of signaling process may be used by applications as indication that data path has become usable. The existence of this delay and the possible failure of cross connection programming, if not properly treated, will result in data loss or even application failure. Characterization of this performance can thus help designers to improve the application model and to build more robust applications. This document defines a series of performance metrics to evaluate the connectivity of data path in the signaling process. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-ccamp-dpm/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-ccamp-dpm/ballot/ No IPR declarations have been submitted directly on this I-D.
