In this paper I investigate several offline and online data transfer scheduling problems and
propose efficient algorithms and techniques for addressing them. In the offline case, I …

Multicast data transfers occur in many distributed systems and applications (eg IPTV, Grids,
content delivery networks). Because of this, efficient multicast data distribution optimization …

Research and education networks (RENs) worldwide, attracted by the benefits of software-
defined networking (SDN) for services involving traffic engineering (TE) such as bandwidth …

In this paper we consider two problems regarding the scheduling of available personnel in
order to perform a given quantity of work, which can be arbitrarily decomposed into a …

Communication flows in distributed systems often present a poor performance, because they
are unaware of each other and end up competing for the same bottleneck resources. A …

In this paper we address several problems regarding content distribution (broadcast) and
communication optimization and scheduling for some restricted classes of graphs (trees …

In this paper we consider several constrained activity scheduling problems in the time and
space domains, like finding activity orderings which optimize the values of several objective …

Many types of distributed systems have been developed and deployed throughout the world
recently, in order to solve various problems or in order to provide novel types of services …

Optimized data transfer services are highly demanded nowadays, due to the large amounts
of data which are frequently being produced and accessed. In this paper we consider …

The focus of the research work presented in this paper is on theoretical and practical
aspects of communication optimization in distributed systems. Communication is a key issue …
