Over the past several years, a significant amount of research has been conducted in the
areas of optical packet switching (OPS) and optical burst switching (OBS). This research has …

We address the dimensioning of infrastructure, comprising both network and server
resources, for large-scale decentralized distributed systems such as grids or clouds. We …

Many distributed applications require a group of destinations to be coordinated with a single
source. Multicasting is a communication paradigm to implement these distributed …

We present a communication paradigm called “anycasting,” which is defined as delivering
traffic from a source node to any one destination among a set of recipients in the network. An …

Optical grids are emerging as a natural, cost-effective platform to meet the needs for
powerful computing, large storage capacity and high-speed data transmission capabilities in …

We define and investigate the problem of multi-resource manycast over optical burst
switched (OBS) networks for supporting distributed computing applications. In multi-resource …

In this paper we discuss the performance of physical-layer impairment-aware anycast
communication over transparent optical networks. High-bandwidth applications, such as grid …

Optical networks play a crucial role in the provisioning of grid and cloud computing services.
Their high bandwidth and low latency characteristics effectively enable universal users …

In this work we propose anycast routing methods to improve the performance of
reconfigurable WDM networks under the variations in the IP traffic. We first investigate …

In recent years, grid computing applications are becoming more and more important to the
scientific and business communities. For many grid applications that require the exchange of …
