MAFIA: A Multicast Management Solution for Access Control and Traffic Filtering

Recently, multicast has seen only marginal wide-scale deployment. One of the main reasons is the lack of support for security and traac management. Although there has been some recent work, these eeorts have not emphasized the critical need to deploy security features side-by-side with management solutions. In this paper, we propose MAFIA, a multicast management solution with the speciic aim of strengthening multicast security through multicast access control, mul-ticast traac ltering, and DoS attack prevention. MAFIA achieves these tasks by making use of information about multicast group memberships available at diierent locations in a network. We have designed various deployment solutions for MAFIA. Among these various solutions, a variety of factors need to be considered. In particular, a solution should have the capability to handle high traac rates, be easy to deploy, and be exible in terms of functionality. We also implement one such solution using the GNU/Linux operating system.
