Application of LDAP in Data Grid of Simulation Resource

This paper discussed the application of directory services in the data grid of the simulation resource based on LDAP(light directory access protocol).To manage the distributed,vast and heterogeneous simulation databases,it needs some extensible query mechanism that can meet the requirement of quick query for the metadata of all kinds simulation databases.This paper puts forward two directory service architectures based on LDAP.Through analyzing two deploying scheme of LDAP server,the pattern of one master and several slaves LDAP server provides an effective query mechanism for the metadata of heterogeneous simulation databases.
