CNRP (Common Name Resolution Protocol)
Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM.
CNRP is an Internet protocol that relieves people from having to remember long and complicated Internet URLs (Universal Resource Locators). Instead, you type in "common names" to access resources. CNRP provides a "resolution service" that converts the common name into an Internet address. See RFC 2972 (Context and Goals for Common Name Resolution, October 2000).
Imagine your looking for a document on your company's Web server. You know it's the February meeting notes. In your Web browser's Address field, you type Feb meeting notes and the document appears. In the background, CNRP has taken your easy-to-remember document name and resolved it into an IP address (for example http://www.company.com/docserver/febmeeting.doc).
Common names and the CNRP protocol may be used in the following applications:
Currently, RealNames uses the protocol at its Web site. Some of the authors of the CNRP protocol work for RealNames. Similar techniques have been implemented, including AOL's KeyWords, CompuServe's Go Words, NetScape Navigator's Smart Browsing, and others. CNRP is an attempt to standardize the concept.
Related topics include URN (Uniform Resource Names), which is a computer-to-computer naming scheme. A URN is a name with global scope that does not imply a location. It has the same meaning everywhere. It provides a persistent identifier for recognizing a resource and providing access to it via a URL (Uniform Resource Locator).
