Abstract
Although IP multicasting has been deployed for more than a decade, management
of multicast networks and service is still a challenging problem. The fact that IP
multicast is a receiver-oriented and stateless protocol makes end-to-end multicast
monitoring intractable task. Important multicast information such as join/leave
status, group membership, tree information, path/traffic characteristics, and session
status is either unrevealed or distributed in various locations on the network. In this
paper, we present a new remote passive multicast monitoring infrastructure, called
MRMON, to capture, analyze and present multicast session, traffic and member-
ship information at real-time. The MRMON probes inhabit a well-organized multi-
cast information structure (MIB) that provides a comprehensive view of multicast
network activities in remote subnets. We show how information can be collected
from different MRMON probes and then correlated to diagnose multicast session
