The present invention provides a
multicast source control method, which comprises: creating
multicast source authentication information; a management platform of the
multicast source authentication information dynamically updating said multicast
source authentication information in accordance with restriction on multicast source; controlling
multicast message sent from the multicast source in accordance with said multicast source
authentication information. The present invention also provides a multicast source
control system comprising a master multicast source
authentication server, a group of slave multicast source
authentication servers, and a predefined node. With the present invention, multicast sources can be performed a control management at the earliest time through initiating authentication requests for multicast sources by the predefined node; the network terminal resources are saved through deploying hierarchical distributed multicast source authentication servers to manage different
multicast address fields; without manual intervention, the master and slave multicast source authentication servers interact for
authentication information periodically and in real time, such that automatic and
real time management of multicast sources can be implemented; and thereby the object of reducing management and maintenance cost as well as improving manageability and
operability of the
multicast network is attained.
