Delay-Tolerant Networking Management Architecture (DTNMA) Delay-Tolerant Networking Management Architecture (DTNMA)
Abstract Abstract
The Delay-Tolerant Networking (DTN) architecture describes a type of The Delay-Tolerant Networking (DTN) architecture describes a type of
challenged network in which communications may be significantly challenged network in which communications may be significantly
affected by long signal propagation delays, frequent link affected by long signal propagation delays, frequent link
disruptions, or both. The unique characteristics of this environment disruptions, or both. The unique characteristics of this environment
require a unique approach to network management that supports require a unique approach to network management that supports

Reports are transmitted by each DA when produced (step 2). Reports are transmitted by each DA when produced (step 2).
At a later time, DM A sends an additional policy to DA B, requesting At a later time, DM A sends an additional policy to DA B, requesting
the production of a report for EDD2 every second (step 3). This the production of a report for EDD2 every second (step 3). This
policy is added to DA B's rule database. policy is added to DA B's rule database.
Following this policy update, DA A will continue to produce EDD1, and Following this policy update, DA A will continue to produce EDD1, and
DA B will produce both EDD1 and EDD2 (step 4). However, DA B may DA B will produce both EDD1 and EDD2 (step 4). However, DA B may
provide these values to the DM in a single report rather than as two provide these values to the DM in a single report rather than as two
independent reports. In this way, there is no direct mapping between independent reports. In this way, there is no direct mapping between
the consolidated reports sent by DA B (step 4) and the two different the consolidated reports sent by DA B (from step 4 onwards) and the
policies sent to DA B that caused that report to be generated (steps two different policies sent to DA B (steps 1 and 3) that produce the
1 and 3). information included in those consolidated reports.
10.5. Multiple Administrative Domains 10.5. Multiple Administrative Domains
The managed applications on a DA may be controlled by different The managed applications on a DA may be controlled by different
administrative entities in a network. The DTNMA allows DAs to administrative entities in a network. The DTNMA allows DAs to
communicate with multiple DMs in the network, such as in cases where communicate with multiple DMs in the network, such as in cases where
there is one DM per administrative domain. there is one DM per administrative domain.
Whenever a DM sends a policy expression to a DA, that policy Whenever a DM sends a policy expression to a DA, that policy
expression may be associated with authorization information. One expression may be associated with authorization information. One
