Post-GEC13 Status report for ORCA-BEN, ORCA-AUG projects

Period: 11/11-03/12

  1. Major accomplishments

Created Camano-3.1-extended release with more robust topology embedding, OpenFlow and better GENI AM API v2 compliance. In a separate branch of code tested a prototype libABAC integration with ORCA. Deployed 3.1-extended with the first two ExoGENI racks. Ran an experimenter tutorial at GEC13 on ExoGENI racks and existing Duke, RENCI, UNC and UH ORCA installations.

  1. Milestones achieved

The Camano-3.1-extended is an intermediate release with topology embedding, GENI AM API and other functions overlayed on top of an older 3.X ORCA code base. Development of a drastically re-factored ORCA 4.0 codebase is also ongoing, with features from 3.1-extended due to be ported to the 4.0 codebase before GEC14. These activities count towards partial fulfillment of ORCAAUG: S4.d ORCA Dungeness 4.0 code release and documentation milestone.

  1. Deliverables made

ORCA Camano-3.1-extended code is available to other ORCA adopters. The code has been deployed into existing infrastructure and the new ExoGENI racks at RENCI and BBN.

  1. Description of work performed during last quarter
  1. Activities and findings
  • Refactored topology embedding code to open for future features (like dynamic stitching of elastic slices) and to be more robust. It is deployed and also ready for integration with 4.0 codebase.
  • Support for OpenFlow was added both as an experimenter mechanism ('please create a vlan-based slice and attach it to my external OF controller') as well as internally in Orca to create VLAN-based slices (without exposing OpenFlow to the experimenters)
  • Initial ABAC integration based on Camano-3.1 codebase was finished. It awaits integration into 4.0 codebase.
  • NDL-OWL -> RSpec ad conversion was implemented to create a more compliant GENI AM API v2 implementation. The existing API implementation was also refined to match the specification wherever possible.
  • As part of another project (NSF-funded SDCI), Orca was ported to run on top of OpenStack with NEuca extensions and the new configuration of compute substrate (using OpenStack) was deployed in the new racks.
