Representing Dynamic Performance Information in Grid Environments with the Network Weather Service

In this paper, we discuss requirements for integrating dynamic performance information from the Network Weather Service (NWS) into the Grid Information Service infrastructure (GIS). We describe the object model that NWS uses internally and provide some rationale for its structure. Finally, we present the NWS 's implementation of a caching LDAP daemon that integrates NWS information into the reference GIS -the Glob s MDS.
