Extreme-scale science applications are highly innovative and constantly evolving. They are expected to generate data in the petabyte and exabyte ranges. This data needs to be transferred, processed, and analyzed at remote locations. A flexible data retrieval service is needed, where a user requesting data retrieval from a remote site can have a choice between replicated storage sites. Elastic Optical...
While the multicast paradigm offers tremendous benefits in efficiency for transmitting data across optical networks, the loss of a destination, or resource, node can result in both the loss of data at the node and the disconnection of an entire established request. We propose an integer linear programming based approach to optimally solve this problem in elastic optical networks, and show that the...
The multicast paradigm offers tremendous benefits in efficiency for transmitting data across optical networks, allowing a single client to send information to an entire set of endpoints. A multicast request is most efficiently provisioned through the creation of a tree, with the end points, or resources, occasionally serving as branching points. This practice can lead to the source of the request...
