Bidirectional Range Extension for TCAM-Based Packet Classification [chapter]

Yan Sun, Min Sik Kim
2010 Lecture Notes in Computer Science  
Packet classification is a fundamental task for network devices such as edge routers, firewalls, and intrusion detection systems.  ...  Our experiments show a more than 75% reduction in the number of TCAM entries by applying the bidirectional range extension algorithm to realworld rule sets.  ...  Then we propose a bidirectional range extension algorithm to solve the range explosion problem based on the non-redundant rule set.  ...
