Abstract: This paper introduces the multi-core network processor OCTEON and the basic development needs based on OCTEON, discusses the design and implementation processes for developing the high precision flow replay system based on this chip under Linux platform, including the communication between the host and OCTEON via PCI, and the timestamp implementation of high precision flow replay and the simultaneous replay of multiple flows. The performance test for this system shows that the flow replay based on OCTEON realizes highly parallel and highprecision processes. The implementation of this system has high application potential for network data flow detection, filter and IDS under high-speed Gbps environment.
Key words: multi-core processor, flow replay, timestamp
