Description détaillée

which implements a simple distributed hashed table; Moreover, by extending with hierarchical structure, it allows to reduce greatly the number of communication among processes.

This class computes index of data which are sent to server as well as index of data on server side with a distributed alogrithm.

Each client has a piece of information about the distribution of servers. To find out all these info, first of all, all client join a discovering process in which each client announces the others about the info they have as well as demand others info they are lacked of. After this process, each client has enough info to decide to which client it need to send a demand for corresponding server of a global index. The alogrithm depends on hashed index.
