Performance Attribute

The Performance attribute provides the base for the entire family of Performance attributes. In addition to its name, it stores four pieces of information about the attribute:

minimum value (lowest possible numeric value allowed)
maximum value (largest possible numeric value allowed)
current value
concatenation rule (algorithm to "add" two attributes of this type)

A Performance attribute returns the number stored in its current value slot when you retrieve the attribute's value. You have to manually edit a Performance attribute to change its current value. The minimum and maximum value numbers are used as constraints when you edit the current value slot.

The default Performance attributes in the netWorks application are

Constant (default:1)
Cost (default:1)
Loss (default:0)
C_NotchNoise (default:0, max:95)
Length (default:0)
ROLR (default:0)
TOLR (default:0)
Capacity (min:0, max:10000)
CallsAttempted (default:0)
CallsBlocked (default:0)

The definitions for the specific attributes can be found in [Bell Labs 1983], [Fennick 1988], and [Bell Labs 1982].
