Abstract
A central controller in a data network can maintain a set of access control list (ACL) rules that represent traffic and data policies of the data network. The controller can autonomously propagate the set of ACL rules to switches in the data network. Each switch that receives the set of ACL rules can selectively install rules from the set based on criteria such as whether or not a given rule in the set is close to the source and device class.
