Relative Weighting
Weighting allows the operator to configure the relative levels of prioritization on which to base the load balancing
decision. One value provides the setting for the load balance rule which determines the relative weighting of the US and
DS channels, which is used to order the channel pairs within a load balance group.
The weight types are described in order of precedence:
a. equal — Directs the load balancer to use DS and US load equally to determine load balance decisions
b. usOnly — Directs the load balancer to use only the US channel load
c. dsOnly — Directs the load balancer to use only the DS channel load
d. usPlus — Directs the load balancer to double the US channel load over DS channel load. Weighting is 66% US and
33% DS.
e. dsPlus — Directs the load balancer to double the DS channel load over US channel load. Weighting is 66% DS and
33% US.
The show cable load-balance policy and show cable load balance channels commands display the load balancing rule’s
channel-weight value. Sample outputs are shown in the Verify the Configuration (page 903) section of this chapter.
Using Multiple Rules
It is possible to configure a policy with more than one load balancing rule. In such cases, the C4/c CMTS uses the following
algorithm to determine which load balancing rules to follow:
