Data Grid environment seek to harness geographically distributed resources that deal with data-intensive problems such as those encountered in high energy physics, bio-informatics, and other disciplines. In general, grids enable the efficient sharing and management of computing resources for the purpose of performing large complex tasks. To be able to sharing data, it is recommended to use the replication technique. This technique provides an improvement in performance, fault tolerance and load balancing. The replication management and its implementation are not simple tasks and produce other problems, like consistency management of replicas. One of the concerns major in the consistency management approaches called optimistic, it is the conflicts resolution among replicas. In this paper we present negotiation mechanisms based on the various negotiation forms between virtual consistency agents to be able to critical situation for sites and to reduce the number of conflicts among replicas to converge them more quickly in data grids.
