Router Naming Convention for rt.ru, 201603

Regular Expressions:

^([a-z]+-crs\d+)-[^\.]+\.ip\.center\.rt\.ru$

Statistics:

Training routers with at least two clustered interfaces: 15
Positive Predictive Value: 0.735
True Positives (green): 36
False Positives (red): 13
IP literals extracted (red): 0
False Negatives, identifier extracted (orange): 4
False Negatives, not matched: 26
Training routers with a single interface in suffix: 9

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
