Description
The
SET FACILITY
command sets the router load balancing and quorum
characteristics of a facility.
Qualifiers
/BROADCAST_MINIMUM_RATE=Bps
/BROADCAST_MINIMUM_RATE=1000
/BROADCAST_MINIMUM_RATE=nnnn
specifies the minimum rate (in bytes per second)
to which flow control can reduce broadcast traffic on outgoing facility links from
the node concerned.
For example, consider a facility has 100 frontends and 99 of them are able to
receive data at a rate of 2KB per second, but one frontend has become congested
and is not able to receive any. This can result in all the frontends slowing down
to the rate that the slowest can accept.
Specifying
/BROADCAST_MINIMUM_RATE=2000
on the router ensures that the 99
frontends receive their broadcasts, and that RTR attempts to send the broadcasts
to the congested frontend. However, broadcasts for the congested frontend are
discarded (if absolutely necessary) rather than slowing down all frontends to the
rate that the slowest can accept.
Specifying /BROADCAST_MINIMUM_RATE without a value gives a default 1000
bytes per second; if you do not use the qualifier then the minimum is zero.
/QUORUM_THRESHOLD=n
/QUORUM_THRESHOLD=0
/QUORUM_THRESHOLD=n
sets the minimum number of nodes/role combinations that
have to be reachable to declare the configuration
quorate
.
