Properly specified, weight factors give some sense of the amount of work that an individual Unified Broker instance can handle. For example, the following table shows the effect of weight factors specified for three Unified Broker instances registered to support the same Application Service.
Table 134. Weight factors based on percentage
Unified Broker name
Weight factor
Percent of time selected
AS1
20

AS2

AS3

The selection algorithm used by the NameServer guarantees that AS1 and AS2 are each selected 20% of the time and AS3 is selected 60% of the time. Thus, if the sum of weight factors for all Unified Broker instances that support the same application adds up to 100, each weight factor specifies the exact percentage of time that the NameServer selects the given Unified Broker instance over time.
