SC461 - High-capacity Data Center Interconnects

Sunday, 08 March
09:00 - 13:00

Short Course Level: Beginner


Dirk van den Borne; Juniper Networks, Germany
Sander L. Jansen; ADVA Optical Networking, Germany
Mark Filer; Microsoft, USA

Short Course Description:

This short course gives a broad overview of data center interconnect (DCI) architectures and technology, ranging from short-haul interconnects of just a few kilometers across a campus network, to metro and finally long-haul deployments. It will cover the latest optical technology developments and how these are used to build ever denser, more power efficient, higher capacity and more scalable data center interconnect links.

We will provide an overview of the different technologies that are most relevant for today’s data center interconnects, covering the full range of transmitter and receiver technologies, pluggable form factors, modulation formats, protocols and data rates. In addition, we will also cover system design aspects such as open line systems, disaggregation of the optical layer and cloud-scale network management and monitoring. We will discuss what makes data center interconnects different from traditional optical transport networks, and what are the most relevant design criteria in today’s DCI deployments. Finally, we will cover in detail the latest standardization activities as well as research and development directions towards future architectures.

The short course should enable attendees to obtain a detailed overview of the different technologies and architectures that are most relevant to wide area data center interconnects and get a comprehensive understanding for the different system design trade-offs in terms of cost, capacity, density, power consumption and complexity.

Short Course Benefits:

This course should enable you to:

  • Describe the typical requirements addressed by data center interconnects, such as transmission distances, system capacity, traffic profiles, data rates, protocols and transmission latency.

  • Understand the system architecture of today’s data center interconnects, and which architectures are typically deployed in enterprise, Tier-2/3 and cloud scale data center deployments.

  • Understand the different transceiver architectures in the context of short-reach DCI, for example direct detection in comparison to coherent detection, and how to leverage the trade-off between optical performance and system complexity / cost.

  • List different flavors of suitable modulation formats and detail the advantages and disadvantages of each method with respect to optical performance, system capacity and power efficiency.

  • Understand industry trends toward network disaggregation and open line systems, as well cloud-scale network monitoring and management.

  • Obtain an overview of the different standardization bodies and activities relevant for data center interconnects such as IEEE, OIF and TIP.

Short Course Audience:

This course is intended for engineers, researchers and technical managers who would like to gain a better understanding of data center interconnect technology, architectures and solutions. Practical network implementations and system design trade-offs will be discussed in detail, such that the participants can obtain a good level of understanding for the challenges of today’s data center interconnect solutions. Participants should have a comprehensive knowledge in the field of fiber-optic transmission systems; no previous knowledge of data center architectures is required.
