The device architecture uses a Ternary Content Addressable Memory (TCAM) to
support packet actions in wire speed.
TCAM holds the rules produced by applications, such as ACLs (Access Control
Lists), Quality of Service (QoS), IP Routing and user-created rules.
Some applications allocate rules upon their initiation. Additionally, processes that
initialize during system boot use some of their rules during the startup process.
