Vijay Vusirikala is currently an Optical Network Architect at Google, where is focused on solutions for scaling and optimizing Google’s optical network covering client optics, metro optical, long haul and submarine links. Prior to Google, Vijay was at Infinera, Motorola and Sycamore Networks in senior marketing, business development and architecture roles working on optical networks and systems ranging from backbone core to access networks. Vijay has published extensively, spoken at numerous industry events, and holds several patents in optical devices and systems. He obtained a Ph.D from the University of Maryland, College Park in optoelectronic integration, and a BSEE from IIT, Madras in India.

The Prospect of Inter-Data-Center Optical Networks
Abstract
Mega data centers and their interconnection networks have drawn great attention in recent years because of the rapid public adoption of cloud-based services. The unprecedented amount of data that needs to be communicated between data centers imposes new requirements and challenges to inter-data-center optical networks. In this article, we discuss the traffic growth trends and capacity demands of Google’s inter-data-center network, and how they drive the network architectures and technologies to scale capacities and operational ease on existing fiber plants. We extensively review recent research findings and emerging technologies, such as digital coherent detection and the flexgrid dense wavelength-division multiplexed channel plan, and propose practical implementations, such as C+L-band transmission, packet and optical layer integration, and a software-defined networking enabled network architecture for both capacity and operational scaling. In addition, we point out a few critical areas that require more attention and research to improve efficiency and flexibility of an inter-data-center optical network: optical regeneration, data rate mismatch between Ethernet and optical transport, and real-time optical performance monitoring.
Still think Cloud Xpress wasn’t designed with Google’s needs in mind?
Let’s take a look at what Vijay used to do at Infinera before starting at Google, per his linkedIn:
