Towards new load-balancing schemes for structured peer-to-peer grids

In this paper, we introduce the concept of a structured peer-to-peer grid and present our contribution to this new world by means of Dermi, a wide-area decentralized object middleware. In addition, we focus on the design and implementation of a load-balancing facility by using the functionalities provided by this middleware. We present two different approaches to achieve load-balancing in our system: a completely decentralized solution by using the anycall abstraction, and a distributed interceptor-based one. Each of them can be used in a wide variety of scenarios, depending on our needs.
