Key Accomplishments/Milestones

• IP Tunneling test suite (iptunnel) integrated into stcnv-gate (Xiang Zhou, October, 2009)
• Clearview IP Tunneling integrated into onnv_125 (Sebastien Roy, September 2009)
• Code-review complete (Sebastien Roy, August 2009)
• 2009/373 approved (Sebastien Roy, August 2009)
• 2009/410 approved (Sebastien Roy, July 2009)
• 2009/373 PSARC Inception (Sebastien Roy, July 2009)
• Code running in production environment 6to4 router (Sebastien Roy, June 2009)
• Completed implementation of non-global zone architecture (Sebastien Roy, June 2009)
• Integrated Fine-Grained Privileges for Datalink Administration (PSARC 2008/473) into onnv_98 (Sebastien Roy, August 2008)
• IP tunnel development has progressed to a point where tunnels can be administered using dladm, and packets flowing over tunnels can be observed using snoop.  The observability of tunnel data-links is one of the primary benefits of this Clearview project component (Sebastien Roy, June 2008)
• Integrated Nemo Generalization into S10U4 (Sebastien Roy, February 2007)
• Added Vanity Naming support to IP tunnels (Sebastien Roy, March 2007)
• Completed merge of IPsec Tunnel Reform and Clearview IP Tunneling (Dan McDonald, Sebastien Roy, April 2007)
• Completed iptun locking infrastructure (Sebastien Roy, June 2007)
• Ability to administer persistent tunnels through dladm (Sebastien Roy, July 2007)
• Completed EOF of Mobile IP (PSARC 2007/311).  Mobile IP was removed from build 72.  (Sebastien Roy, August 2007)
• Early-access to Clearview IP Tunneling made available with the release of Clearview build 74 to OpenSolaris (see the announcement on the networking community mailing list)
