Proportional Distribution

The ProportionalDistribution operation performs distribution of call processing down one or more exit paths according to a configured ratio/proportion for each exit path.

The ProportionalDistribution operation must have at least one exit. The ProportionalDistribution operation is only useful when it has more than one exit, although this is not enforced by the operation definition.

Config Parameters

The ProportionalDistribution operation config attributes are as follows.

Parameter	Type	Description
`rules`	Array of Object	[Required] The `rules` Array must contain one or more Objects.

Config Rules

The attributes for each ProportionalDistribution operation rules Object are as follows.

Parameter	Type	Description
`proportion`	Integer	[Required] The relative proportion of calls that should be routed to the specified exit.
`exit_idx`	Integer	[Required] The zero-based index number of the exit to use for routing the specified proportion of calls.

Note that the sum of proportion values does not need to add up to 100.

Example Operation

Here is an example ProportionalDistribution operation in JSON representation.

    {
        "id": 5,
        "type": "ProportionalDistribution",
        "config": {
            "rules": [
                { "proportion": 50, "exit_idx": 0 },
                { "proportion": 50, "exit_idx": 1 }
            ]
        },
        "exits": [ 4, 17 ]
    }

In this example, 50% of calls will proceed via exit index 0 to the operation with ID 4, while the other 50% of calls will proceed via exit index 1 to the operation with ID 17.

Exits

In general, the user interface should ensure that the entries in exits match 1:1 with the configured rules, although this is not enforced by the operation definition.

Exit Index	Name	Description
`0`	Proportion #1	[Required] All `ProportionalDistribution` operations must have at least one exit.
`1`	Proportion #2 +	Additional exits may be present.
