NAME

       dtpcrc - Delay-Tolerant Payload Conditioning management commands file

DESCRIPTION

       DTPC management commands are passed to dtpcadmin either in a file of text lines or
       interactively at dtpcadmin's command prompt (:).  Commands are interpreted line-by line,
       with exactly one command per line.  The formats and effects of the DTPC management
       commands are described below.

COMMANDS

? The help command. This will display a listing of the commands and their formats. It
is the same as the h command.

# Comment line. Lines beginning with # are not interpreted.

e { 1 | 0 }
Echo control. Setting echo to 1 causes all output printed by dtpcadmin to be logged
as well as sent to stdout. Setting echo to 0 disables this behavior.

v Version number. Prints out the version of ION currently installed. HINT: combine
with e 1 command to log the version number at startup.

1 The initialize command. Until this command is executed, DTPC is not in operation on
the local ION node and most dtpcadmin commands will fail.

a profile profileID maxRtx aggrSizeLimit aggrTimeLimit TTL class_of_service
report_to_endpointID [statusReportFlags]
The add profile command. This command notes the definition of a single DPTC
transmission profile. A transmission profile asserts the BP and DTPC configuration
parameter values that will be applied to all application data items (encapsulated in
DTPC application data units and transmitted in bundles) that are issued subject to
this profile. Transmission profiles are globally defined; all transmission profiles
must be provided, with identical parameter values, to all inter-communicating DTPC
protocol entities.

profileID must be the positive integer that uniquely defines the profile.

maxRtx is the maximum number of times any single DTPC ADU transmitted subject to the
indicated profile may be retransmitted by the DTPC entity. If maxRtx is zero, then
the DTPC transport service features (in-order delivery, end-to-end acknowledgment,
etc.) are disabled for this profile.

aggrSizeLimit is the size threshold for concluding aggregation of an outbound ADU and
requesting transmission of that ADU. If aggrSizeLimit is zero, then the DTPC
transmission optimization features (aggregation and elision) are disabled for this
profile.

aggrTimeLimit is the time threshold for concluding aggregation of an outbound ADU and
requesting transmission of that ADU. If aggrTimeLimit is zero, then the DTPC
transmission optimization features (aggregation and elision) are disabled for this
profile.

class_of_service is the class-of-service string as defined for bptrace(1).

report_to_endpointID identifies the BP endpoint to which all status reports generated
from bundles transmitted subject to this profile will be sent.

statusReportFlags, if present, must be a sequence of status report flags, separated by
commas, with no embedded whitespace. Each status report flag must be one of the
following: rcv, ct, fwd, dlv, del.

d profile profileId
The delete profile command. This command erases the definition of the DTPC
transmission profile identified by profileId.

i profile profileId
This command will print information (all configuration parameters) about the profile
identified by profileId.

l profile
This command lists all known DTPC transmission profiles.

s The start command. This command starts the DTPC clock and daemon tasks for the local
BP node.

x The stop command. This command stops all DTPC tasks and notifies all DTPC
applications that DTPC service has been stopped.

w { 0 | 1 | <activity_spec> }
The DTPC watch command. This command enables and disables production of a continuous
stream of user-selected DTPC activity indication characters. A watch parameter of "1"
selects all DTPC activity indication characters; "0" de-selects all DTPC activity
indication characters; any other activity_spec such as "o<r>" selects all activity
indication characters in the string, de-selecting all others. DTPC will print each
selected activity indication character to stdout every time a processing event of the
associated type occurs:

o new aggregator created for profile and destination endpoint

\< new ADU aggregation initiated

r application data item added to aggregation

\> aggregation complete, outbound ADU created

- outbound ADU sent via BP

l ADU end-to-end acknowledgment sent

m ADU deleted due to TTL expiration

n ADU queued for retransmission

i inbound ADU collector created

u inbound ADU received

v ADU sequence gap detected

? inbound ADU discarded

* ADU sequence gap deleted due to impending ADU TTL expiration

$ inbound ADU collector reset

h The help command. This will display a listing of the commands and their formats. It
is the same as the ? command.

EXAMPLES

       a profile 5 6 1000000 5 3600 0.1 dtn:none
           Notes the definition of DTPC transmission profile 5: transport services are enabled,
           with an end-to-end retransmission limit of 5; transmission optimization service is
           enabled, initiating bundle transmission whenever the aggregation of data items queued
           for transmission subject to this profile exceeds one million bytes or is more than
           five seconds old; the transmitted bundles will have one-hour lifetime, will not be
           subject to custody transfer, will be sent at "standard" priority, and will not be
           tracked by any bundle status report production.
