Many structured Peer-to-Peer systems for data management face the problem of load imbalance. To address this issue, there exist almost as many load balancing strategies as there are different systems. Besides, the proposed solutions are often coupled to their own API, making it difficult to port a scheme from a system to another. In this report, we show that many load balancing schemes are comprised of the same basic elements, and only the implementation and interconnection of these elements vary. Based on this observation, we describe the concepts behind the building of a common API to implement any load balancing strategy independent from the rest of the code. We then show how this API is compatible with famous existing systems and their load balancing scheme. Implemented on our own distributed storage system, this API integrates well with the existing system and has a minimal impact on its business code. Moreover, this can allow changing only a part of a strategy without modifying its other components.
