摘　　要：该设计是基于BCM57XX嵌入式系统的应用.采用了一种特殊的旁路技术,避开了复杂的端口管理,使得其硬件电路设计较为简洁.在保证正常的通信的同时,实现抓包,同时针对千兆口的抓包特点,设计了多口抓包技术,通过多台计算机同时进行抓包,对流量进行分抓.对于二层交换机或是不带镜像功能的交换机来说更是合适,它避开了软件抓包的某些不足,具有结构简单,使用方便,造价低廉的特点,极大地扩大了抓包的使用环境和效率.The design is based on application of embedded system. It avoids the complexity of the port management as adopted a special bypass technology and makes the hardware circuit design simpler. It implements the packets sniffered and guaranteed the normal communication at the same time. All the while we have designed a multi--port capture technology to sniffer simultaneously according the Gigabit ports characters. The design has a simple structure, an easy way to use and low cost features. It expands the use of packet capture environment and efficiency.
