A Survey of Application-level Multicast Group Communication and a Proposal for Intelligent Reflectors

摘要

The article proposes the state of the art in techniques and models designed to solve issues in application-layer IP multicast. Specifically, the issue of group communication for distributing video flows using reflectors to participants at a videoconference is considered. A proposed solution is introduced, involving an algorithm capable of dynamically discovering the appropriate reflector to meet a given client's needs. Simulations results show the efficiency of using reflectors in this type of application.
