The infrastructure of grid information service constituted with highly distributed information providers and aggregate directory is brought forward on the basis of the characteristic of grid information resources in this paper. The Lightweight Directory Access Protocol (LDAP), one of the base protocols, is also analyzed in this paper. It is put forward that LDAP is a distributed database. The dynamic updating and replication of LDAP directory tree happens frequently. To solve the problem, it has been proposed that the strategy of fast spread and Cascading spread can boost the efficiency of grid information service system. Moreover, we use file-parted replication approach to divide the LDAP database file into several blocks that are replicated parallel between LDAP sever points then. In such a way, the system efficiency of parallel processing can be boosted by margin. In addition, based on the idea forenamed, we put forward the technique infrastructure and upload-controlling algorithm, both of which are proven to be effective in improving the system efficiency.
