Understanding Clusters

Cluster Establishment Process

This section describes how a cluster is established.

Fault-triggered Switchover and Traffic Diversion

This section describes the fault-triggered switchover and traffic diversion processes in different networking conditions.

Traffic Flow Aggregation

For services that must have consistent forward and return paths, when the actual traffic flow forward and return paths are inconsistent, flow aggregation can be implemented in the cluster to aggregate traffic flows to the same device for processing.

Service Data and Configuration Backup

This section describes the configuration and service data backup of cluster members after a cluster is created.

Cluster Configuration Management

This section describes how to manage the unified configuration UI for cluster members.

Members Leaving the Cluster
