Research Laboratory The IP multicast has not been widely used by current internet
service operators, and part of this relates to the nature of multicast,
which is designed to allow any host to receive or send multicast
traffic
to the network. Internet service operators do not want to risk their
network operation without sufficient control of the multicast sources
and receivers and protection against the Denial of Service (DoS)
attacks. Work under the multicast control concentrates on specifying
and implementing a controlled multicast framework that can be used to
control the multicast receivers and sources. The control mechanism
should improve multicast network performance and protect multicast
groups from DoS attacks.
