Short Name:  Segment Function Diversity

Description: SR paths contain one or more segments. Each segment contains a locator and an function. The compression mechanism must be able to represent SR paths whose segments are diverse from one another with respect to function. The following are examples of function:

  *   Loosely routed forwarding
  *   Strictly routed forwarding

Rational:

  *   In TI-LFA, repair paths frequently contain both loosely and strictly routed segments
  *   Traffic engineered paths frequently contain both loosely and strictly routed segments

Metric: The compression mechanism must be able to represent an SR path that contains any valid combination of segment types.
