Grid infrastructures often rely on centralised services for resource management and quota enforcement. This is an efficient approach for small and mid-size grids, but it is a potential bottleneck in case of large-scale infrastructures. Furthermore, additional installation and maintenance work is needed to provide a fault-tolerant solution.This paper presents a decentralised, fault-tolerant, and scalable quota enforcement protocol. By utilising the concept of diffusive load balancing, unused resource quotas dedicated to projects are equally balanced over all supporting nodes. This enables the enforcement of upper resource bounds, while being adaptive to changes in resource demands.
