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.
