Calculation method
Calculation method
Transitive reachable ordered zone pairs, excluding self
Breadth-first reachability from every zone; self pairs are excluded even in cycles.
Reachable pairs absent from supplied expected set
Compare every reachable pair to the literal expected pair list; do not assume expected permissions are transitive.
Expected pairs with no directed path
Expected pairs absent from graph reachability.
Reachable pairs requiring more than one supplied edge
Reachable pair with shortest directed path length≥2 edges.
Reachable share of distinct ordered zone pairs (%)
Reachable pair count/(n×(n−1))×100; undefined for one zone.
Symbols and units
- a
- Known network zone IDs joined by |
- b
- Directed connections: source, destination; or none
- c
- Explicitly expected reachable pairs: source, destination; or none
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- A supplied directed-connectivity reachability model, not a network scan or proof of access. It assumes edges compose into paths and ignores routing policy, firewall conditions, identities and packet state. No connections are attempted.
