In communication networks that span large geographical regions, transfer of bulk data is
often costly and hard to manage. One prominent reason for that is bandwidth contention …

The increasing demand of bulk data transfer imposes significant challenges in inter-
datacenter networks that span multiple domains. Storing data temporarily at domain borders …

To meet the increasing inter-datacenter traffic, datacenter storage is brought in the
forwarding path. Bulk data that are delay-tolerant can be temporarily stored and forwarded …

The time-and space-varying nature of residual bandwidth in inter-datacenter networks (inter-
DCNs) makes conventional end-to-end connections difficult to fully utilize the residual …

Steerable free-space optics (FSO) communications are flexible in link reconfiguration (LR),
and easy to deploy, especially when the available physical space is limited. Thus it is …

In the recent past, there has been an explosive growth in data traffic within data center
systems. This rapid increase in data volume has put significant constraints on the speed of …

The rise of emerging services has brought a rapid growth in bulk data transfers across inter-
datacenter (DC) wide area networks (WANs). To accommodate the demands of such …

Traffic fluctuations make conventional end-to-end delay-sensitive (DS) transfers difficult to
fully utilize the residual bandwidth in the inter-datacenter networks. In this paper, we …

Increasing bulk data transfers incur peak-hour bandwidth contention between bulky and
short flows as well as between bulky flows. To mitigate this contention, storage is introduced …
