Data-intensive applications that operate on large volumes of data have motivated a fresh
look at the design of data center networks. The first wave of proposals focused on designing …

The ever-growing society of information has its backbone on a complex network of optical
links among nodes where data are stored and processed. These nodes are mostly …

We experimentally evaluate the network-level switching time of a functional 23-host
prototype hybrid optical circuit-switched/electrical packet-switched network for datacenters …

Recent proposals have employed optical circuit switching (OCS) to reduce the cost of data
center networks. However, the relatively slow switching times (10--100 ms) assumed by …

A detailed examination of evolving traffic characteristics, operator requirements, and network
technology trends suggests a move away from nonblocking interconnects in data center …

The basic building block of ever larger data centers has shifted from a rack to a modular
container with hundreds or even thousands of servers. Delivering scalable bandwidth …

The potential advantages of optics at high link speeds have led to significant interest in
deploying optical switching technology in data-center networks. Initial efforts have focused …

Intra-data-center traffic is estimated to be about four times global Internet traffic and is
continuously increasing. Applying optical switching to data center networks will increase …

The rising tide of data-intensive, massive scale cluster computing is creating new challenges
for traditional, hierarchical data center networks. In response to this challenge, the research …

Applying optical switching to data center networks can greatly expand network bandwidth
and reduce electrical power consumption, both of which are needed to meet the explosive …
