....can be captured. However, accuracy of the information and its temporal validity is limited to that of the accuracy and refresh rate of the routers cache respectively. Merit Networks has developed a suite of tools that rely on state information maintained by routers for gathering monitoring data[20]. This suite includes tools like mstat, mrtree, and mview. These tools use SNMP to collect all manner of data from routers. Mstat queries SNMP enabled router for information about various routing tables and packet statistics. Mrtree performs cascaded SNMP queries on routers to discover a ....

....at the network layer. It records the DVMRP route updates issued by the local multicast routers and uses the collected data for monitoring the stability of the DVMRP from the point of view of the local network. Another set of tools use SNMP[5] to collect network statistics. Mstat, mrtree, and mview[10] can collect all manner of data from routers. However, because SNMP queries require passwords, these tools are more suitable for performing monitoring on an Intranet. Another factor that limits SNMP based tools are the lack of updated standards and Management Information Bases (MIBs) for the newer ....

....for IGMP messages, and a table 11 with information about which interfaces currently have members listening to particular multicast groups. Two important freeware tools which work with multicast MIBs are mstat[43] and mview[44] Both are tools produced by the Merit SNMP Based Management Project[45]. Mstat queries a router or SNMP capable mrouted to generate various tables of information including routing tables, interface configurations, cache contents, etc. Mview is an, application for visualizing and managing the MBone. Mview allows the user to display and interact with the topology of ....
