Jaime Llorca

Jaime Llorca is a Research Professor at the NYU Tandon School of Engineering's Electrical and Computer Engineering Department. He previously held a Senior Research Scientist position with the Network Algorithms Group at Nokia Bell Labs, NJ, a Communication Networks Research Scientist position with the End-to-End Networking Group at Alcatel-Lucent Bell Labs, NJ, and a post-doctoral position with the Center for Networking of Infrastructure Sensors, College Park, MD. He received M.S. and Ph.D. degrees in Electrical and Computer Engineering from the University of Maryland, College Park, MD. His research interests are in the fields of network algorithms, network optimization, machine learning, and distributed control, with applications to next-generation communication networks, mobile/edge/cloud computing, end-to-end service orchestration, cloud-network resource allocation, and content distribution. He has made fundamental contributions to the mathematics of content delivery and distributed cloud networks, including pioneering cooperative caching, network coding, and cloud network control algorithms. He is one of the co-inventors (and co-author of 5 associated patents) of "cache-aided coded multicasting", a content delivery technology that allows serving unicast demands via cache-enabled coded multicast transmissions. He also introduced "cloud-network flow", a generalization of multi-commodity flow that allows efficiently optimizing distributed applications that consume both cloud (compute and storage) and network resources. He has authored more than 100 peer-reviewed publications and 20 patents. He currently serves as an Associate Editor for the IEEE/ACM Transactions on Networking. He is a recipient of the 2007 Best Paper Award at the IEEE International Conference on Sensors, Sensor Networks and Information Processing, the 2016 Best Paper Award at the IEEE International Conference on Communications, and the 2015 Jimmy H.C. Lin Award for Innovation.

Jaime leads the NYU research activities of the NSF RINGS funded project Resilient Delivery of Real-Time Interactive Services over NEXTG Compute-Dense Mobile Networks, in collaboration with Professor Elza Erkip and Research Professor Antonia Tulino at the NYU Tandon, and Professor Andreas Molisch at USC.

Abstract:
Real-time interactive (RTI) services are anticipated to be the ‘’next big thing” in information technology, merging the fields of sensing, communication, and computation that until recently have been treated separately. In traditional systems, these building blocks are not optimized to work with each other, and particularly not in real-time, constraining the type of services that can be offered. RTI services require real-time aggregation of distributed data streams onto edge/cloud compute servers that can process data as soon as it is generated while delivering automated actions and interactive experiences. The goal of this project is to develop an integrated cloud-network resource allocation framework as well as dynamic control algorithms to provide such RTI services with guaranteed quality of experience. Results will benefit the US economy by enabling more efficient, reliable, and resilient automation services, e.g., smart cities, factories, farms, as well as seamless mixed reality experiences for e.g., distributed collaboration, social networking, and entertainment. 

The project designs a comprehensive mathematical framework and concrete algorithms for reliable and resilient delivery of RTI services. In a first thrust, the project explores the limits of delivering latency-critical services reliably. The establishment of the reliable network stability region provides bounds on how much offered RTI traffic a network can support. A packet-lifetime-based queuing model serves as the basis of Lyapunov-drift-inspired control algorithms that not only account for packet delays but also take costs such as energy consumption into account. A second thrust of the project develops robust NextG network control algorithms that can adapt to dynamic network states. Integration of the approaches in the first two thrusts under a common Lyapunov drift control framework is an avenue to enable reliable and resilient RTI service delivery, which is verified by the implementation of the algorithms on the COSMOS PAWR (Platform for Advanced Wireless Research) community testbed.
