NAME

imcfw - bundle route computation task for the IMC scheme

SYNOPSIS

imcfw

DESCRIPTION

imcfw is a background "daemon" task that pops bundles from the queue of bundle destined
for IMC-scheme (Interplanetary Multicast) endpoints, determines which "relatives" on the
IMC multicast tree to forward the bundles to, and appends those bundles to the appropriate
queues of bundles pending transmission to those proximate destinations.

For each possible proximate destination (that is, neighboring node) there is a separate
queue for each possible level of bundle priority: 0, 1, 2. Each outbound bundle is
appended to the queue matching the bundle's designated priority.

Proximate destination computation is determined by multicast group membership as resulting
from nodes' registration in multicast endpoints, governed by multicast tree structure as
configured by imcadmin(1).

imcfw is spawned automatically by bpadmin in response to the 's' (START) command that
starts operation of Bundle Protocol on the local ION node, and it is terminated by bpadmin
in response to an 'x' (STOP) command. imcfw can also be spawned and terminated in
response to START and STOP commands that pertain specifically to the IMC scheme.

EXIT STATUS

"0" imcfw terminated, for reasons noted in the ion.log log file. If this termination was
not commanded, investigate and solve the problem identified in the log file and use
bpadmin to restart imcfw.

"1" imcfw could not commence operations, for reasons noted in the ion.log log file.
Investigate and solve the problem identified in the log file, then use bpadmin to
restart imcfw.
