摘要： A method and system for providing a remote switching engine to monitor and control network traffic and utilizing appended word source address port mapping is provided. The system comprises a number of ports, at least one local switching device, at least one local forwarding database, and a remote switching processing device. The ports are provided for sending and receiving frames. The local switching device performs high-speed switching. The local forwarding database corresponds and couples to the local switching device, the database allowing the local switching device to look up a known address that has been previously obtained and forward the frames based on the known address. The remote switching processing device receives and processes frames from the local switching device(s). The local switching device(s) learns associations between Media Access Control (MAC) addresses and ports by having the local switching device forward unknown address frames to the remote switching processing device. The remote switching processing device update the local forwarding database corresponding to the local switching device based on the forwarded frames, utilizing the appended word source address mapping. The appended word of a frame transmitted from one switching device to another switching device has encoded within an ingress engine number and port number.
摘要翻译：提供了一种用于提供远程交换引擎来监视和控制网络流量并利用附加字源地址端口映射的方法和系统。该系统包括多个端口，至少一个本地交换设备，至少一个本地转发数据库和远程交换处理设备。端口用于发送和接收帧。本地交换设备执行高速切换。本地转发数据库对应并耦合到本地交换设备，数据库允许本地交换设备查找先前已经获得的已知地址，并且基于已知地址转发帧。远程交换处理设备接收并处理来自本地交换设备的帧。通过使本地交换设备将未知地址帧转发到远程交换处理设备，本地交换设备学习媒体访问控制（MAC）地址和端口之间的关联。远程交换处理装置利用所附加的字源地址映射，基于转发的帧来更新对应于本地交换设备的本地转发数据库。从一个交换设备发送到另一交换设备的帧的附加字已经在入口引擎号码和端口号内编码。
