buf: Buffers Information Base
The buffers “buf” information base contains variables that describe the
router’s use of two types of global memory buffers: message buffers,
which facilitate internal process-to-process communication, and packet
buffers, which facilitate external communications by temporarily storing
incoming or outgoing data packets. The structure is the following:
buf
[slot #]
*
type stands for either msg or pkt, both
containing the same variables
variables listed below
The pathname is constructed as follows:
buf[slot #].type.variable
The variables are listed alphabetically:
corrupted contains the number of times a corrupted buffer was
deleted.
free contains the number of message or packet buffers available for
internal VME transfers or external transfers, respectively. Because
router operations and application software modules impose some over-
head on global memory buffers, the number of buffers available for data
transfers is less than the total number of buffers allocated when the
router boots.
init contains the number of message or packet buffers allocated when
the router booted.
min contains the smallest number of message or packet buffers
available since the router booted.
