ABSTRACT. Event correlation is an essential service for tracking the system behavior and discov­
ering the root of failures or performance problems. Next generation network services are mostly
distributed and large­scale in term of number of managed objects and geographical distribu­
tion. This requires supporting scalable event correlation that handle large number of managed
objects with minimal event propagation. Using an efficient group management and communica­
tion framework that facilitates exchanging the monitoring information among agent groups and
managers is a key issue in developing next generation scalable event correlation services. How­
ever, the dynamic behavior inherent with concurrent event generation and correlation poses a
major challenge in agents' group membership assignment. This paper presents an efficient
group management structure based on IP multicast that minimizes exchanging messages (e.g.,
event/control information) and provides a highly flexible group communication framework for
