EDG 2.0 components :

•  EDG Replica Manager - The next generation replica management services. A detailed description of its architecture is here. This is the coordinating service of all other services and is the major entry point for users and applications.

•  RLS Replica Location Service - The next generation Replica Catalog, this service has been designed together with the Globus Project. The improvements over the Replica Catalog are manyfold: It provides no restrictions on naming and is a distributed scalable service. See the design document for details. Globus/ISI has developed the first release of the RLS, WP2 has developed a java RLS client and a pure-java LRC server. The RLI is in the works.

 
•  RMC Replica Metadata Catalog - The metadata catalog for Replica Management Services. This metadata catalog provides access to metadata on Logical Files and Collections. It is being used by the Replica Manager to store access control lists, transactional information and other metadata.

 
•  ROS Replica Optimization Service - The service interfacing to the network cost and storage access cost functions of WP7 and WP5. This component is provided by the Optimization Task.

•  GDMP - Grid Data Mirroring Package, formerly Grid Data Management Pilot. This is the 'oldest' middleware package of WP2, originating in the CMS experiment where it was used in production to automatically replicate Objectivity database files over the wide area.

 
•  edg-replica-manager - The replica management module to be used for single-file replication tasks and for the interaction with the replica catalog (like registering a file).

 
•  Replica Catalog - The currently deployed replica catalog is the Globus Replica Catalog with a few command-line additions. There is also a secured version that is GSI-enabled.

 

 

WP2 has provided a C++ interface to this LDAP based RC (see GDMP) and a Replica Catalogue server installation RPM with a conversion tool. For more information, refer to our LDAP Replica Catalogue Server page. 

•  Replica Catalog GUI - A Graphical User Interface to the RC.
