| Abstract: | : | Data-centers (DCs) are key repositories that both store and process
information. With the exponential growth of the Internet, the
data-center becomes a key element towards the convergence of
communication and computation, and its architecture further becomes
ever-so-important. Scalable data-center architecture is a much
sought-after topic of research. The key issue being the ability to
create a non-blocking architecture that can provide ample (100%
bisection) bandwidth between servers in the data-center as well as
sizable bandwidth between servers and the Internet connections to the
data-center. Concepts in literature range from variants of Clos
networks (Google’s Portland and Seattle project), to hierarchical
multi-degree interconnection (Microsoft’s VL2 and B-Cube) to the use
of optics to provide an interconnection pattern (Helios, OSA and
Mordia – all from Google). However, these architectures do not scale
beyond a few thousand nodes (servers) and even then, require some sort
of smart addressing as well as technological novelty (such as fast
optical switching) – all of which are not easy to implement.
We propose FISSION or Flexible Interconnection of Scalable Systems Integrated using Optical Networks – a data-center architecture that can scale to a million nodes accompanied with an addressing/routing protocol. We first describe the FISSION architecture, showing how it can scale to a million nodes using off-the-shelf optics and indigenously developed electronics. We discuss the protocol for addressing and routing in FISSION as well as issues such as VM-migration, the use of an SDN controller, robustness post a failure etc. We highlight a test-bed that was developed to demonstrate the FISSION concept, thus validating the concept, as well as a simulation model that compares FISSION to other competing architectures. Finally, we also provide a simple proof that shows the near-infinite scalability of the FISSION concept, paving the way for excellent optical-electrical integration – something that is deeply desired for supercomputing, cloud and data-center environments.
