Router Naming Convention for mit.edu, 201110

Regular Expressions:

^(.+rtr-\d+)-[^\.]+\.mit\.edu$
^[^\.]+\.(.+)\.mit\.edu$

Statistics:

Training routers with at least two clustered interfaces: 20
Positive Predictive Value: 1.000
True Positives (green): 59
False Positives (red): 0
IP literals extracted (red): 0
False Negatives, identifier extracted (orange): 0
False Negatives, not matched: 2
Training routers with a single interface in suffix: 1

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
