Attentiveness monitoring in multicast systems |
摘要 |
A method of sending packets to a multiplicity of subscribers in a multicast subscription system includes monitoring the activity at a NACK server. The method also includes disturbing the flow of data between the sender and the subscribers. The latter may include creating a NACK generation incident in order to determine if the sender has any attentive subscribers.
