Figure 54: Relationship between the main configuration items
Figure 47 shows the relationship between the following configuration items:
Link group—A collection of links that contain similar functions. A link group can be referenced by a virtual server or an LB action.
Link—Physical links provided by ISPs.
Virtual server—A virtual service provided by the LB device to determine whether to perform load balancing for packets received on the LB device. Only the packets that match a virtual server are load balanced.
LB class—Classifies packets to implement load balancing based on packet type.
LB action—Drops, forwards, or modifies packets.
LB policy—Associates an LB class with an LB action. An LB policy can be referenced by a virtual server.
Sticky group—Uses a sticky method to distribute similar sessions to the same link. A sticky group can be referenced by a virtual server or an LB action.
Parameter profile—Defines advanced parameters to process packets. A parameter profile can be referenced by a virtual server.
