A set of plugins, modules and interfaces were developed for the OpenDaylight (ODL) SDN controller to enable and extend the ODL capabilities for Padtec Lightpad optical ROADM devices. This software stack was made possible through the successful collaboration between the R&D teams from California Institute of Technology HEP Networking team in US, UNICAMP and UNESP universities in Brazil, along with their industry partner Padtec. This new development consists of: Southbound

CMS PhEDEx Data Transfers
Hardware Setup Below is a short summary of the hardware setup used by the team during the SC14 demonstration. PDF file can also be downloaded here. Multiple storage servers equipped with high speed HBAs and SSDs were used. These servers were spread between three booths: Caltech, LAC/iCAIR and Vanderbilt. Each of the servers had 36 SSDs, split between 3 disk controllers (12 SSDs/controller). The capacities of the SSDs varied from

MonALISA
MonALISA, stands for Monitoring Agents using a Large Integrated Services Architecture, has been developed by Caltech and its partners with the support of the U.S. CMS software and computing program. The framework is based on Dynamic Distributed Service Architecture and is able to provide complete monitoring, control and global optimization services for complex systems. The MonALISA system is designed as an ensemble of autonomous multi-threaded, self-describing agent-based subsystems which are registered

FDT
FDT – One of the key advances in this demonstration was Fast Data Transport (FDT; http://monalisa.cern.ch/FDT), a Java application developed by the Caltech team in close collaboration with the Polytehnica Bucharest team. FDT runs on all major platforms and uses the NIO libraries to achieve stable disk reads and writes coordinated with smooth data flow across long-range networks. The FDT application streams a large set of files across an open TCP socket,
