Router Naming Convention for nasa.gov, 201412

Regular Expressions:

^([a-z]+-[a-z\d]+-[a-z\d]+\.[a-z]+)\.nasa\.gov$

Statistics:

Training routers with at least two clustered interfaces: 1
Positive Predictive Value: 1.000
True Positives (green): 2
False Positives (red): 0
IP literals extracted (red): 0
False Negatives, identifier extracted (orange): 0
False Negatives, not matched: 0
Training routers with a single interface in suffix: 3

Legend:

Green	+	Inferred identifier, true positive when evaluated against training data
Orange	-	Inferred identifier, false negative when evaluated against training data
Red	!	Inferred identifier, false positive when evaluated against training data
Red	x	Inferred identifier, but contains part of IP address literal embedded in hostname
	~	False negative, not matched
	o	No regex matched the interface, but the interface was the only interface in this suffix on the router
	*	A filter regex matched the interface
