  • Local area network receive filter
    Patent number: 6256307
    Abstract: Filtering of network packets is performed. Within a filter controller, a base address for a range of addresses is stored. A second value is also stored which further specifies the range of addresses. When a network packet is received, a network controller extracts a destination address from the network packet. The network controller forwards the destination address to the filter controller. The filter controller compares the destination address to the range of addresses specified by the base address and the second value. The filter controller generates a signal which indicates when the destination address is outside the range of addresses.
