DESCRIPTION
"The MIB for managing Server Load Balancing Manager(s),
such as the Cisco IOS SLB product.
This MIB includes instrumentation for the manager-side
implementation of the Dynamic Feedback Protocol (DFP).
A DFP uses the DFP protocol to communicate with
DFP agents in order to obtain information about
Servers.
This MIB includes the objects required for implementing
the load balancer management side of the
Server/Application State Protocol (SASP). The load
balancer is responsible for registering Members with a
SASP-Agent. A Member is an entity that is defined on
the load balancer to service Internet traffic. The
responsibility of the Agent is to monitor the Members,
and report a recommended weight to the load balancer.
The weight is then used in load balancing decisions.
Acronyms and terms:

SlbPredictor ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The predictor represents the load-balancing algorithm
being used on a server farm to distribute load evenly
among real servers.
'roundRobin' : assign evenly amongst real servers.
'leastConns' : assign to the real server with the least
number of current connections.
'ipHash' : assign based on the hash value of the
source IP and destination IP address.
'ipHashSrc' : assign based on the hash value of the
source IP address.
'ipHashDest' : assign based on the hash value of the
destination IP address.
'urlHash' : assign based on the hash value of the
URL string.
'forward' : forward the connection to the
appropriate next-hop as determined by
a routing lookup on the destination
IP address.
'leastLoaded' : assign to a real server that is
least loaded/busy. The load
information is available from
