The rising demand for WAN capacity driven by the rapid growth of inter-data center traffic
poses new challenges for costly optical networks. Today cloud providers rely on fixed optical …

In this work we propose Shoofly, a network design tool that minimizes hardware costs of
provisioning long-haul capacity by optically bypassing network hops where conversion of …

Optical networks continue to play an essential role in scaling network capacity at a
dramatically reduced unit bandwidth cost, and the next generation of technology will …

Today's traditional, hierarchical, full-electronic data centers cannot guarantee quality of
service (QoS) for latency-sensitive applications or carrier-grade multitenancy. We propose …

A comparative analysis of datacenter network architecture trade-offs between traditional Top-
of-Rack-based architectures using copper server connectivity versus deploying fiber to the …

With Internet traffic doubling almost every other year, data-center (DC) scalability is destined
to play a critical role in enabling future communications. While many DC architectures are …

Enterprises and cloud providers are moving away from deployment of large-scale data
centers and towards smallto mid-sized data centers because of their lower implementation …

Software-Defined Optical Networking (SDON) signifies a revolutionary paradigm in optical
network management and provisioning. It leverages the power of software-defined …

This article discusses prospects and challenges of software defined elastic optical
networking for grid and cloud computing environments. We exploit OpenFlow-based unified …

Optical transport networks are progressively being designed around reconfigurability.
Operators require an infrastructure capable of carrying large amounts of data, but also able …
