Understanding SLB
This section describes the concepts and principles of SLB.

Implementation Mechanism
-
This section describes the common concepts and principles of SLB.
-
Load Balancing Algorithms
-
Load balancing algorithms determine how the FW distributes traffic to servers. An appropriate load balancing algorithm brings desired load balancing effect.
-
HTTP Scheduling Policy
-
An HTTP scheduling policy determines how the FW distributes traffic to a server group. An HTTP scheduling policy and load balancing algorithm work together for better load balancing.
-
Sticky Session
-
The sticky session function enables the FW to allocate the traffic from one client to the same real server within a specific period of time.
-
Service Health Check
-
The service health check function checks whether services on a server are available to prevent traffic from being distributed to a server that does not function properly, which causes service interruption.
