NAME¶
ltpclo - LTP-based BP convergence layer adapter output task
SYNOPSIS¶
ltpclo [-]
remote_node_nbr
DESCRIPTION¶
ltpclo is a background "daemon" task that extracts bundles from
the queues of segments ready for transmission via LTP to the remote bundle
protocol agent identified by
remote_node_nbr and passes them to the
local LTP engine for aggregation, segmentation, and transmission to the remote
node. If
remote_node_nbr is preceded by a '-' character, then all LTP
transmission performed by
ltpclo will be "green" (unreliable)
transmission, without acknowledgment and retransmission.
Note that
ltpclo is not a "promiscuous" convergence layer
daemon: it can transmit bundles only to the node for which it is configured,
so scheme configuration directives that cite this outduct need only provide
the protocol name and the outduct name (the remote node number) as specified
on the command line when
ltpclo is started.
ltpclo is spawned automatically by
bpadmin in response to the 's'
(START) command that starts operation of the Bundle Protocol, and it is
terminated by
bpadmin in response to an 'x' (STOP) command.
ltpclo can also be spawned and terminated in response to START and STOP
commands that pertain specifically to the LTP convergence layer protocol.
EXIT STATUS¶
- "0"
- ltpclo terminated normally, for reasons noted in the ion.log
file. If this termination was not commanded, investigate and solve the
problem identified in the log file and use bpadmin to restart the
BRSC protocol.
- "1"
- ltpclo terminated abnormally, for reasons noted in the
ion.log file. Investigate and solve the problem identified in the
log file, then use bpadmin to restart the BRSC protocol.
FILES¶
No configuration files are needed.
ENVIRONMENT¶
No environment variables apply.
DIAGNOSTICS¶
The following diagnostics may be issued to the
ion.log log file:
- ltpclo can't attach to BP.
- bpadmin has not yet initialized Bundle Protocol operations.
- No such ltp duct.
- No LTP outduct with duct name matching remote_node_nbr has been
added to the BP database. Use bpadmin to stop the LTP
convergence-layer protocol, add the outduct, and then restart the LTP
protocol.
- CLO task is already started for this duct.
- Redundant initiation of ltpclo.
- ltpclo can't initialize LTP.
- ltpadmin has not yet initialized LTP operations.
