【摘要】 针对网络由不同的网络产品所构成的情况,给出了一种基于SNMP协议的物理拓扑发现算法,依据现有的理论得出结论。该算法以简单的方式,完整、高效地进行了物理拓扑发现,在子网中可以检测到HUB和不支持SNMP协议的交换机。更多还原

【Abstract】 This paper describes a algorithm of physical topology which is made up of elements of multi-vendor,which bases on standard SNMP protocol.A theorem is educed in terms of theories of seniorities and practice.Based on this theorem a kind of better algorithm is proposed,which can discover physical layer topology in a simple,complete and efficient way.The algorithm can be applied to discover hubs and bridges that don’t support SNMP protocol in subnet.更多还原
