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.

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
