 A distributed data network across Tier 3 sites has been deployed using xrootd, which is a file access protocol. The current configuration allows one to read CERN Root data files using the TFile::Open method. Queries for files are sent to redirectors hosted at sites, and which connect to data servers. A client queries the redirector for a file, the redirector checks whether its assigned data servers possess that file, and if so send the hostname and location of the file to the client. ​ A distributed data network across Tier 3 sites has been deployed using xrootd, which is a file access protocol.
