Abstract
The Remote network-MONitoring (RMON) standard is a valuable addition to
the Simple Network Management Protocol (SNMP), providing network managers with
important global network information. Unlike SNMP agents, RMON agents operate
in promiscuous mode and process all packets traversing the local net. The RMON
management information base (MIB) supplements the SNMP MIB-II standard MIB.
We present common network problems that cannot be solved using existing MIB-II
or RMON objects. To solve these problems, we develop extensions to the RMON
matrix group to gather network layer statistics that result in a view of
packet traffic beyond the local network. Our extensions increase the ability
to analyze and solve network configuration problems and perform
troubleshooting. We demonstrate our results by implementing and analyzing two
"live" internetworking problems. Data collected from these experiments
showed that network traffic patterns can be isolated by individual subnets,
thus more easily identifying sources of congestion.
Keywords: Network management; RMON; SNMP; MIB; internetwork.
