A method of hardware support for high-speed data capture at 40 Gbps and beyond

摘要

Current high speed networks have reached a throughput capacity in practical implementation of up to OC-768. Current commercial of the shelf (COTS) hardware cannot meet the requirements for full data capture at these rates. In this paper, we first provide an analysis of capabilities of best available hardware. We then propose a method for non-standard configuration of hardware to provide for high speed data capture at 40 Gbps and beyond. This configuration will provide a suitable hardware back-end to enable transport, storage, and processing of the 40+ Gbps full duplex captured data to enable forensics without disposing of any potentially valuable information.
