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.
