Dynamic Delegation Discovery System (DDDS) Part One: The Comprehensive DDDS
Alternative Format: Original Text Document
RFC 3401 DDDS - The Comprehensive DDDS October 2002 This document along with RFC 3402, RFC 3403 and RFC 3404 obsoletes RFC 2168 [8] and RFC 2915 [6], as well as updates RFC 2276 [5]. This document will be updated and or obsoleted when changes are made to the DDDS specifications. Thus the reader is strongly encouraged to check the IETF RFC repository for any documents that obsoletes or updates this one. 3. The Algorithm The DDDS algorithm is defined by RFC 3402 [1]. That document defines the following DDDS concepts: o The basic DDDS vocabulary. o The algorithm. o The requirements on applications using the algorithm. o The requirements on databases that store DDDS rules. RFC 3402 is the actual DDDS Algorithm specification. But the specification by itself is useless without some additional document that defines how and why the algorithm is used. These documents are called Applications and do not actually make up part of the DDDS core specification. Applications require databases in which to store their Rules. These databases are called DDDS Databases and are usually specified in separate documents. But again, these Database specifications are not included in the DDDS core specification itself. 4. DDDS Applications No implementation can begin without an Application specification, as this is what provides the concrete instantiation details for the DDDS Algorithm. Without them the DDDS is nothing more than a general algorithm. Application documents define the following: o the Application Unique String (the thing the delegation rules act on). o the First Well Known Rule (the Rule that says where the process starts). o the list of valid Databases (you can't just use any Database). o the final expected output.
