Greetings All: We have submitted the draft that proposes Generic Overlay OAM framework and Datapath Failures detection mechanisms.
Please review the same update us with your valuable comments/feedback. Warm Regards, - Authors A new version of I-D, draft-jain-nvo3-overlay-oam-01.txt has been successfully submitted by Kanwar Singh and posted to the IETF repository. Name: draft-jain-nvo3-overlay-oam Revision: 01 Title: Generic Overlay OAM and Datapath Failure Detection Document date: 2014-02-12 Group: Individual Submission Pages: 44 URL: http://www.ietf.org/internet-drafts/draft-jain-nvo3-overlay-oam-01.txt Status: https://datatracker.ietf.org/doc/draft-jain-nvo3-overlay-oam/ Htmlized: http://tools.ietf.org/html/draft-jain-nvo3-overlay-oam-01 Diff: http://www.ietf.org/rfcdiff?url2=draft-jain-nvo3-overlay-oam-01 Abstract: This proposal describes a mechanism that can be used to detect Data Path Failures of various overlay technologies as VXLAN, NVGRE, MPLSoGRE and MPLSoUDP and verifying/sanity of their Control and Data Plane for given Overlay Segment. This document defines the following for each of the above Overlay Technologies: o Encapsulation of OAM Packet, such that it has same Outer and Overlay Header as any End-System's data going over the same Overlay Segment. o The mechanism to trace the Underlay that is exercised by any Overlay Segment. o Procedure to verify presence of any given Tenant VM or End-System within a given Overlay Segment at Overlay End-Point. Even though the present proposal addresses Overlay OAM for VXLAN, NVGRE, MPLSoGRE and MPLSoUDP, but the procedures described are generic enough to accommodate OAM for any other Overlay Technology.
