Scope

The scope of work on this project is to extend ORCA (a candidate GENI control framework) to include the optical resources available in https://ben.renci.org BEN metro optical testbed. Also, to make a reference implementation of ORCA available to additional GENI prototypes and assist, with limited support, in the integration of ORCA into select wireless/sensor prototypes. The team will operate a clearinghouse for the various testbeds under the ORCA control framework. Also, connect with the NLR backbone network FrameNet service to facilitate end-to-end VLAN's connections into BEN. Finally, make the integrated (VLAN connections and control framework) ORCA/BEN infrastructure available to external researchers by the end of Year-1.

Current Capabilities

ORCA (Cluster D) Clearinghouse
ORCA clearinghouse equipment location: RENCI, 100 Europa Drive, Chapel Hill, NC.
ORCA clearinghouse will use RENCI public IP addresses.
The ORCA clearinghouse at RENCI is now operational.
Go to Cluster D Clearinghouse at RENCI ; get login from Ilia Baldine
These Cluster D projects have installed (moved) their broker to the clearinghouse: BEN(?); DOME; ViSE; Kansei

ORCA/BEN Integration
On July 7, 2009, the ORCA/BEN team demonstrated to the GENI Project office the ORCA capability to create slices of substrate that include several transit providers, i.e. BEN and NLR.
See "ORCA/BEN Integration Demo with Stitching of VLANs between BEN and NLR", July 7, 2009 and "ORCA/BEN Integration Demo July 7, 2009, web site
This satisfied milestones 1c, 1d and 1e.
The overall demo connectivity was:

The demo used ORCA calls to create several VMs at Duke, RENCI and UNC-CH BEN PoPs and then linked them together with VLANs via NLR and BEN:

NLR VLANs were statically provisioned ahead of time via Sherpa.
BEN VLANs were created dynamically, and included provisioning of Infinera DTN circuits as well as fiber paths using Polatis switches.
BEN node at RENCI used port TenGig 2/2 and Duke used TenGig 2/1.

We do not use NDL in the demo to provide the broker or site authority with resource accounting information – this is a Spiral 2 enhancement.

In this demo the NDL request describing a desired BEN connection is passed from the Slice Manager directly to the BEN Transit Authority as part of the redeem procedure. The Slice Manager first acquires a VLAN tag ticket from the VLAN broker and attaches the NDL to this ticket before passing it to the BEN Transit Authority. The BEN Transit Authority then validates the ticket and uses the NDL description of the request to compute the cross‐layer path across BEN.

In the BEN Transit Authority, NDL is also used in the form of the BEN catalogue. This NDL catalogue is pre‐loaded into the Jena ontology engine at the start of the demo. The BEN Transit Authority relies on the contents of the catalogue to compute the cross‐layer path (i.e. which network elements need to be configured) and provide handler/drivers with necessary configuration information.

Because the contents of the ontology is dynamically updated during the demo, the BEN Transit Authority path computation algorithm is intelligent enough to take advantage of the existing links whenever possible (existing links are added to the ontology as the demo progresses). For example, in the case of two slices, the first slice across BEN establishes a fiber connection between respective fiber switches and a DWDM connection between Infinera DTNs. The second slice, aware of the existence of these links based on the contents of the ontology, does not require any fiber switch or Infinera configuration steps and simply configures another VLAN in the 6509 over the existing DWDM connection.
