In this Paper, a novel architecture for IDS based on a reconfigurable hardware, a FPGA, coupled with a commodity Gigabit Ethernet MAC(XGM) is proposed. 文中提出了用可重配置硬件(FPGA)和商用千兆以太网MAC(XGM)实现的网络入侵检测系统体系结构。
When network flow is high, software-based network packet capturing program will loss some packets, and to meet the demand of high-speed network, this paper designs a data-capturing program based on Gigabit Ethernet MAC(XGM). 针对基于软件实现的网络数据包捕获方案在网络流量较大时会因丢包而产生漏检的缺点,本文设计实现了基于硬件的千兆以太网MAC(XGM)捕获方案,以应对高速网络的需求。
Gigabit Ethernet technology is widely used in Local Area Network ( LAN ) recently, Layer 2 ( MAC ) switch chip is the key chip based on which Gigabit Ethernet technology can be used. 千兆以太网(GigabitEthernet)技术目前被广泛应用于局域网中,千兆以太网二层(MAC层)交换芯片是千兆以太网中的关键芯片。
