SFC module and Kademlia overlay

Changed:
<
<		This server software implements the component responsible for constructing a Kademlia-based overlay supporting the storage and querying of metadata files and can be downloaded from here. The indexing is based on Space Filling Curves (Z-curve or Hilbert curve). The initialization of the nodes that accommodate the enabled operations in the Metadata overlay is accomplished by the execution of peerPlatform.py. The description of the nodes and the indexing method is included in a INI file, which is given as parameter to the specific executable.

The initialization of the nodes that accommodate the enabled operations in the Metadata overlay is accomplished by the execution of peerPlatform.py. The description of the nodes and the indexing method is included in a INI file, which is given as parameter to the specific executable (-c option). Examples of INI files for the media scenario (here), the banking scenario (here) and keyword searches (here) have been attached.
 

GridTorrent

GridTorrent constitutes the data transfer layer of the Gredia middleware. Based on peer-to-peer techniques, it allows clients to download files from multiple sources while uploading them to other users at the same time, rather than obtaining them from a central server. At the same time, it takes advantage of the striped version of GridFTP protocol to directly communicate with GridFTP servers. Moreover, instead of the centralized RLS Grid component, GridTorrent relies on a Kademlia-based overlay for efficient and scalable Replica Location.
