  • Big data and Optical Lightpaths Driven Data Center Network

    T. S. Eugene Ng

    • Abstract: Physical layer optical communication devices such as optical circuit switches give data center network architects new tools to innovate. The abundant bandwidth capacity of optical devices seems a great match for the insatiable bandwidth demand of big data applications emerging in data centers today. However, big data applications have many important nuanced qualities and they have to be carefully understood and considered by network architects. This talk will discuss some of the recent advances from the BOLD (Big data and Optical Lightpaths Driven) Project at Rice University, which has been investigating big data applications' fundamental characteristics and developing advanced data center network architectures that leverage optical devices to meet the growing challenges presented by big data applications.

Call for Oral Presentations

Optical equipment is a fundamental component of modern systems. Today, nearly all wide-area, metro, and data center communications are carried over optical technology making optics a billion dollar industry. Optics is poised to play an even bigger role in next-generation networks. The high bandwidth and ultra-low latency requirements of modern Cloud-centric systems, such as machine learning and business analytics, are hard to meet in a cost-effective manner with traditional electrical devices.

The OptSys workshop focuses on the design and implementation of optical networked systems for the next-generation Cloud infrastructure. These systems pose a number of research challenges spanning multiple research areas, e.g., physical layer, scheduling, synchronization, congestion control, orchestration, and topology reconfiguration, which require cross-layer and cross-disciplinary solutions. The workshop aims to bring together participants across the optics, networking, systems, and distributed algorithms community to jointly tackle these challenges and foster discussions and collaboration opportunities across these communities.

Topics of Interest

Topics of interest include, but are not limited to, the following areas:

  • Cross-layer optimization problems
  • Systems design leveraging recent advances in Optical technology
  • Optical designs leveraging recent advances in Systems and Cloud
  • Novel optical network architectures
  • Emerging optical technologies impacting the design of rack-scale, data-center, metro, and wide-area networks
  • New congestion control and network stacks for optical networks
  • Scheduling and time synchronization algorithms for microsecond/nanosecond Optical Circuit Switches
  • Programming abstractions for orchestration between the SDN/IP layer and optical devices
  • Reconfigurable optical topologies
  • Analysis and experience with operational optical networks
  • Models, algorithms, and theory for optical networks
  • Economic and cost aspects of optical networks
  • Monitoring and diagnosis of performance issues across layers
  • Free-space optical interconnects

Submission Instructions

Submissions include an extended abstract for oral presentation at the workshop. Authors are encouraged to submit an extended abstract that includes previously published work. Submitted papers must use the new ACM template (using sigconf document type) from the 2018 ACM consolidated template package (you can also use this barebone LaTeX template). The font size must be 9 points. The length of the final extended abstract with all its content except references must not exceed 1 page. The extended abstract must include author’s names and affiliations for single-blind peer reviewing by the PC. Use this link for submission: Abstracts will not be published.


Attendance of the workshop is by open registration and subject to the same registration fees and rules as all the other SIGCOMM 2019 workshops. The registrants of the workshop may freely attend any workshop on the same day.
