基于LLDP的家庭网络设备自动识别的研究

摘要

This paper investigates the automatic device identification in home network by the Link Layer Discovery Protocol. When the device is connected to the home network ,the home gateway can get various information of the device. LLDP is a vendor independent protocol and can enable network devices to spread their own signs and information to sub-networks, the home gateway automatically identifies the network devices by getting endpoint information stored in management information base (MIB) of network devices. Because home network is oriented towards non-professional users, automatic identification makes the setup and maintenance of the home network smarter, easier and more convenient.%主要研究家庭网络中设备的自动识别,提出了利用LLDP技术,使得家庭设备一旦接上家庭网络,家庭网络网关就能获取关于设备的各类信息.LLDP作为一种与厂商无关的协议,可以使网络设备向子网中传播自己的标识和信息,家庭网关通过获得存放在网络设备MIB(Management Information Base)中的信息,来自动识别网络设备.因为家庭网络面向的是非专业用户,所以自动识别使得家庭网络的配置更加的智能,维护更加简单、方便.
