-Most of the time, asynchronous load balancing algorithms have extensively been
-studied in a theoretical point of view. The Bertsekas and Tsitsiklis'
-algorithm~\cite[section~7.4]{bertsekas+tsitsiklis.1997.parallel}
-is certainly the most well known algorithm for which the convergence proof is
-given. From a practical point of view, when a node wants to balance a part of
-its load to some of its neighbors, the strategy is not described. In this
-paper, we propose a strategy called \emph{best effort} which tries to balance
-the load of a node to all its less loaded neighbors while ensuring that all the
-nodes concerned by the load balancing phase have the same amount of load.
-Moreover, asynchronous iterative algorithms in which an asynchronous load
-balancing algorithm is implemented most of the time can dissociate messages
-concerning load transfers and message concerning load information. In order to
-increase the converge of a load balancing algorithm, we propose a simple
-heuristic called \emph{virtual load} which allows a node that receives a load
-information message to integrate the load that it will receive later in its
-load (virtually) and consequently sends a (real) part of its load to some of its
-neighbors. In order to validate our approaches, we have defined a simulator
-based on SimGrid which allowed us to conduct many experiments.

use this concept, load balancing messages must be sent using two different kinds
of messages: load information messages and load balancing messages. More
precisely, a node wanting to send a part of its load to one of its neighbors,
very quickly. In opposition, load balancing messages are often bigger and thus
require more time to be transferred.
