Item Description
Scheduler
Select an algorithm that a real service group uses to distribute services and
traffic:
•
Round Robin—Assigns new connections to each real service in turn.
•
Weighted Round Robin—Assigns new connections to real services based
on the weights of real services. A higher weight indicates more new
connections will be assigned.
•
Least Connections—New connections are always assigned to the real
service with the fewest number of active connections.
•
Weighted Least Connections—New connections are always assigned to
the real service with the fewest number of weighted active connections
(the number of active connections/weight).
•
Random—Assigns new connections to real services randomly.
•
Weighted Random—Assigns new connections randomly to real services
based on their weights; a higher weight indicates more new connections
will be assigned.
•
Source Address Hashing—Assigns a new connection to a specific real
service based on the source address of the connection. This algorithm
makes sure new connections with the same source address can be
assigned to the same real service.
•
Source Address Port Hashing—Assigns a new connection to a specific
real service based on the source address and port of the connection. This
algorithm makes sure new connections with the same source address and
port can be assigned to the same real service.
•
Destination Address Hashing—Assigns a new connection to a specific
real service based on the destination address of the connection.
IMPORTANT:
Destination address hashing is applicable to firewall load balancing mode and
other algorithms are applicable to server load balancing.
Health Monitoring Method
Select a health monitoring method that a real service group uses to monitor
its real services.
IMPORTANT:
The health monitoring method specified for the real service group takes effect
for a real service that has the same health monitoring method specified.
Otherwise, the health monitoring method specified for the real service takes
effect.
Health Monitoring Success
Criteria
Specify the health monitoring success criteria.
•
If you select All, health monitoring succeeds only when all the selected
health monitoring methods succeed.
•
If you select At Least and specify a value, health monitoring succeeds
when the number of succeeded health monitoring methods reaches the
specified value.
