Data Center Summit: Open Hardware and Software Platforms
Organizers: Ramon Casellas, CTTC, Spain; Daniel King, University of Lancaster, UK; Noboru Yoshikane, KDDI Research, Japan, Ilya Baldin, RENCI/UNC Chapel Hill, USA
Session I: Open Platforms for Optical Innovation
In the first session of the Summit, invited speakers will provide an overview of key frameworks, architectures and projects within the trend of using open hardware and software platforms for designing, deploying and operating large-scale networks and complex commercial environments, showcasing the benefits behind the concepts of Software Defined Networking (SDN) and Network Functions Virtualization (NFV).
The session presentations will be technology oriented, and will include both the point of view of the operator/user of the platform and that of the system vendor / integrator. For the former, focus will be on key benefits such as reduction of operational expenses and automation of network control or service provisioning. For the latter, the target is to provide an overview of key projects, including relevant architectural elements and main drivers and innovation opportunities.
The session will cover CORD (Central Office Re-architected as a Datacenter), highlighting how datacenter economics and cloud flexibility can be applied in scenarios such as the Central Office or Access networks and, from an open optical platform perspective, OpenROADM, a project that develops interoperability specifications for creating software-controlled Reconfigurable Optical Add/Drop Multiplexers (ROADM) that operate on open hardware, in view of the functional disaggregation and programmability through an open application programming interface (API) that can be accessed through an SDN controller. Finally, the Abstraction and Control of Traffic Engineered Networks (ACTN) framework will be described, along its ongoing implementation on top of the ONOS network operating system.
Session II: SDN/NFV Demo Zone
Using open hardware and software platforms for designing, deploying and operating large-scale networks is increasingly seen as a viable strategy for large and complex commercial environments. Most recently, the concepts of open hardware and software are being used within the optical infrastructure domain, and this trend is expected to facilitate innovation, design, adoption and control of future optical infrastructure.
Open hardware initiatives, including the Open Compute Platform, Telecom Infrastructure Project, Open ROADM Multi-Source Agreement, Central Office Rearchitected as Datacenter and Open Platform for NFV are defining open hardware platforms and reference implementations. To facilitate their control and operation, software projects such as OpenStack, OpenDayLight, Open Network Operating System, Open Platform for NFV, Open Source Mano and OpenConfig, are providing extensible frameworks and software tools.
Numerous proof-of-concept implementations and distributions across various research projects and early stage commercial initiatives, have demonstrated that rapid innovation is possible on basis of open hardware, interfaces, and software. Increasingly, these implementations and distributions will have to support the growing need for open optical hardware platforms.
