NAME
udpbso - UDP-based best-effort link service output task for BSSP
SYNOPSIS
udpbso {remote_engine_hostname | @}[:remote_port_nbr] txbps remote_engine_nbr
DESCRIPTION
udpbso is a background "daemon" task that extracts BSSP segments from the queue of segments bound for the
indicated remote BSSP engine, encapsulates them in UDP datagrams, and sends those datagrams to the
indicated UDP port on the indicated host. If not specified, port number defaults to 6001.
UDP congestion can be controlled by setting udpbso's rate of UDP datagram transmission txbps
(transmission rate in bits per second) to the value that is supported by the underlying network.
Each "span" of BSSP data interchange between the local BSSP engine and a neighboring BSSP engine requires
its own best-effort and reliable link service output tasks. All link service output tasks are spawned
automatically by bsspadmin in response to the 's' command that starts operation of the BSSP protocol, and
they are all terminated by bsspadmin in response to an 'x' (STOP) command.
EXIT STATUS
"0" udpbso 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 bsspadmin to restart
udpbso.
"1" udpbso terminated abnormally, for reasons noted in the ion.log file. Investigate and solve the
problem identified in the log file, then use bsspadmin to restart udpbso.
FILES
No configuration files are needed.
ENVIRONMENT
No environment variables apply.
DIAGNOSTICS
The following diagnostics may be issued to the ion.log log file:
udpbso can't initialize BSSP.
bsspadmin has not yet initialized BSSP protocol operations.
No such engine in database.
remote_engine_nbr is invalid, or the applicable span has not yet been added to the BSSP database by
bsspadmin.
BE-BSO task is already started for this engine.
Redundant initiation of udpbso.
BE-BSO can't open UDP socket
Operating system error. Check errtext, correct problem, and restart udpbso.
BE-BSO can't bind UDP socket
Operating system error. Check errtext, correct problem, and restart udpbso.
Segment is too big for UDP BSO.
Configuration error: segments that are too large for UDP transmission (i.e., larger than 65535 bytes)
are being enqueued for udpbso. Use bsspadmin to change maximum segment size for this span.
