Common Indexing Protocol (Paperback)

High Quality Content by WIKIPEDIA articles! The Common Indexing Protocol (CIP) was an attempt in the IETF working group FIND during the mid-1990s to define a protocol for exchanging index information between directory services. In the X.500 Directory model, searches scoped near the root of the tree (e.g. at a particular country) were problematic to implement, as potentially hundreds or thousands of directory servers would need to be contacted in order to handle that query. The indexes contained summaries or subsets of information about individuals and organizations represented in a white pages schema. By merging subsets of information from multiple sources, it was hoped that an index server holding that that subset could be able to process a query more efficiently by chaining it only to some of the sources: those sources which did not hold information would not be contacted.
