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.
