  1. LEARNSpiral 2 Year-end Project Review University of Houston PI: Deniz Gurkan co-PI: Keren Bergman Staff: Paul RobertsStudents: Debjyoti Majumder, Michael Wang, Caroline Lai, BalagangadharBathula, Cathy Chen August 26, 2010

  2. Project Summary • This project will integrate the Lone-star Education And Research Network (LEARN) regional optical network, located in Texas, into the ORCA control framework (GENI Cluster D). This will enable GENI researchers to utilize the LEARN network for L2 (VLAN) transport. • This project will also work with the Embedded Real-time Measurements (ERM) project to develop methods to include the use of existing commercial transport and measurement equipment for real-time measurements. Specifically, it will work with the ERM project to define the API and implement Measurement Handler software to utilize an existing interface (TL1 over SSH) into the Infinera Digital Transport Node (DTN) to make optical measurements.

  5. Accomplishments 1: Advancing GENI Spiral 2 Goals • Control Framework Integration • LEARN VLAN mapping • Architecture and hardware design with Cisco 3400 switches on LEARN nodes • ORCA handler development • Instrumentation and Measurement • Physical layer measurement handler software: an interface and protocol support to an optical layer box – Infinera DTN on BEN • perfSONAR workshop attendance (see poster in next slide): developed draft schemas for perfSONAR methods of client request and response to optical physical layer measurements • Participated in the feedback control experiments on optical physical layer within IMF group August 26, 2010

  6. Poster at perfSONAR Workshop August 26, 2010

  7. Accomplishments 2:Other Project Accomplishments • Community development in the region • GENI rack proposal support by Texas institutions and LEARN through teleconferences and raising awareness on the GENI infrastructure in LEARN August 26, 2010

  8. Issues • Pending connectivity on LEARN: • Personnel support of this project at UH has been on/off due to job restructuring of the main contact person • Coordination of LEARN partners and other institutions demands a proactive approach such as organization of a workshop to raise awareness and discuss/resolve roadblocks • Coordination with perfSONAR to receive timely feedback on development of interoperable schemas applicable to optical physical layer measurements August 26, 2010

  9. Plans • Control framework support to extend ORCA in LEARN through deployment of Cisco 3400 switches on participating campuses • UH-Rice will be up before the end of Spiral-2 (September 30, 2010) • TAMU and UT-Austin deployments will be active during Spiral-3 • Deployment of perfSONAR measurement points on Texas sites where GENI infrastructure is being built • Creation of perfSONAR wrappers for physical layer measurements as drafted in the poster attached • Utilize measurement capabilities of perfSONAR to support cross-layer communication and optimization (as defined in IMF and ERM projects). • The GPO is starting to formulate goals for Spiral 3. What are your thoughts regarding potential Spiral 3 work? • Concrete best practices in connectivity with national backbones for us to inform our regional optical networks • Participate in the emerging I&M system architectures to deliver physical layer and other measurements in the integrated infrastructures of this project August 26, 2010
