In this paper, we present a framework for realizing low-cost Internet monitoring systems that can handle gigabit-rate without any special hardware. As a result of the spread of Gigabit Ethernet technologies, there is a need for inexpensive solutions that can realize Internet monitoring systems with gigabit-rate capability. However, it is quite diffcult for existing software-based systems to collect all the packet headers at a gigabit rate, even if high-end hardware components are used. We therefore propose a novel framework for gigabit-rate packet header collection that can be applied to most network interface cards. This framework also provides a capability for forwarding the collected header information to other hosts via a network, which makes it easy to integrate existing applications and to introduce load-balancing mechanisms. The results of our performance evaluation show that our first implementation is capable of collecting 100% of header information, even if a Gigabit Ethernet link is fully utilized by 384-byte packets, while existing software-based systems can collect less than 50%, even though the CPU load is more than twice as large.
