Abstract
A method for processing ternary content-addressable memory (TCAM) data. The method may include transmitting a search query to a TCAM device. The TCAM device may store a plurality of TCAM entries. The method may further include obtaining a first matched entry and a second matched entry from the plurality of TCAM entries. The method may further include obtaining, from software precedence data, a first precedence value for the first matched entry and a second precedence value for the second matched entry. The method may further include comparing, using a priority criterion, the first precedence value for the first matched entry with the second precedence value for the second matched entry to select a resultant entry. The priority criterion may determine a precedence order that a computing device uses the plurality of TCAM entries. The method may further include processing, using the computing device, the resultant entry.
