  • Using CRC-15 as hash function for MAC bridge filter design
    Patent number: 7620043
    Abstract: A hash function for a MAC bridge filter that improves bridge performance by reducing overflow of the MAC bridge database and which reduces cost of the device by using relatively few hardware resources. A CRC hash function is used to randomize the search string in the MAC bridge filter so that a consistent bridge performance is achieved regardless of where the bridge is used. Using the CRC as a hash function also results in efficient hardware implementation. In addition, the present invention may be generalized to use a CRC-M as hash function for any bridge filter design.
