The WCCP protocol provides the assignment method for dynamic symmetric and asymmetric load distribution in a cluster. WCCP detects node failures and performs redistribution based on the configuration communicated to it by Content Gateway.
One or more distribution attributes are selected. Typically the destination IP address is used.
If load is to be distributed to different cluster members in different proportions, a weight value is set on each cluster member. These values determine the proportion of requests each will receive relative to other members of the cluster.
Asymmetric load distribution using the weight value is helpful when:
How the weight value supports asymmetric load distribution:
