Abstract
Methods and apparatus for implementing an access list key for accessing information associated with a packet from an access list are disclosed. The packet includes an IP source address field and an IP destination address field, the IP source address field including an IP source address and the IP destination address field including an IP destination address, the IP source address and the IP destination address each having a number of bits (e.g., 128 bits in the case of IPv6). An IP source address is obtained from the IP source address field of the packet and an IP destination address is obtained from the IP destination address field of the packet. A modified IP source address is generated from the obtained IP source address such that the number of bits in the modified IP source address is less than the number of bits in the obtained IP source address. In addition, a modified IP destination address is generated from the obtained IP destination address such that the number of bits in the modified IP destination address is less than the number of bits in the obtained IP destination address. The access list key is then composed from the modified IP source address and the modified IP destination address.
