HP-UX IPFilter Version 16 Performance White Paper

IPFilter filters IP packets by reading the network protocol headers and comparing the values to a set of user-configured rules. Based on these rules, IPFilter either passes or drops the packet. Because IPFilter only reads the protocol headers, the size of an IP packet does not affect the speed at which IPFilter processes the packet, and IPFilter incurs the same overhead for an IP packet regardless of packet size. This white paper document HP-UX IPFilter version 16 performance on HP-UX 11i v3 systems using 10 Gigabit Ethernet (10GigE) and 1 Gigabit Ethernet (1GigE) links.
