Using aspect oriented programming to build a portable load balancing service

Scaling applications to large networks and an increasing number of users has been for years a technical challenge. Today, technologies are well known to scale applications to local networks but scaling to large networks with high latency is still a challenge. The DLBS (dynamic load balancing service) brings new solutions regarding large scale load balancing for middleware based applications. DLBS offers a multi-criteria and easily customizable load balancing service. It consists of a scalable monitoring infrastructure, a connection manager (integrated into the middleware) and customizable load balancing strategies. Implementation of a low level service requires in order to stay efficient to avoid the necessity for high overhead. DLBS aims to be a generic load balancing service and an easy and efficient portability with a CORBA object request broker has been possible thanks to aspect oriented programming.
