异构以太网物理拓扑发现的简单算法

Simple Algorithm of Physical Topology Discovery in Heterogeneous Ethernet

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。

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.
