Abstract
A system may include a content addressable memory (CAM) that is configured to include multiple services, receive a key, where the key includes source port information and IP information related to a packet received on one of multiple ports, and output a match index value in response to a search of the CAM using the key. The system may include a policy memory module that is configured to receive the match index value and to output meter controls and a meter address based on the match index value, a port meter map module that is configured to receive the source port information and to output a mask value and a per port meter value, and a remapping module that is configured to receive the meter address, receive the mask value and the per port meter value, and modify the meter address based on those values.
