【摘要】 该文通过对MIB-II定义的路由表、地址转换表等信息的分析,描述了一种基于SNMP和Java的网络拓扑发现方法。该方法发现结果比较准确,对于设备接口之间连接关系在配置了VLAN的网络中也能很好地发现。另外,由于不向网络中注入过多的探测数据包,该方法对网络正常流量不会产生较大影响。更多还原

【Abstract】 I n this thesis,we firstly analyze the definition of tables such as route table ,address mapping table in MIB-II framework and then discuss a network topology discovery method based on the SNMP protocol and Java language.Precise discove ry result can be gained using this method.Relationship among equipment physica l interfaces can be correctly discovered in the network with VLAN.Besides,this method affects little on the normal network traffic as it does not inject many check packets into network.更多还原
