Central Directory

Meaning – A central directory, or a central directory server, is a network node that is responsible for maintaining a directory of resources throughout the network. The CDS server provides some similar function to that of a CMC host in a subarea network. While a CMC is a central place for network management information that operates and controls the network, a CDS manages only the directory functions, not the operational and network management functions that a CMC also provides.

When a network node needs to search for a resource, it first sends request to the central node, which then searches for the location of the resource and relays it to the respective network node.

Example of usage“If the resource is still not found, the central directory server notifies the node that originally requested the search that the search is unsuccessful.”
