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:
DFP Dynamic Feedback Protocol
SASP Server to Application State Protocol
GGSN Gateway GPRS Support Node
GPRS General Packet Radio Service
GTP GPRS Tunneling Protocol
SASP Server/Application State Protocol
