20140204940 | SCALABLE TRANSPORT METHOD FOR MULTICAST REPLICATION - Embodiments disclosed herein provide advantageous methods and systems that use multicast communications via unreliable datagrams sent on a protected traffic class. These methods and systems provide effectively reliable multicast delivery while avoiding the overhead associated with point-to-point protocols. Rather than an exponential scaling of point-to-point connections (with expensive setup and teardown of the connections), the traffic from one server is bounded by linear scaling of multicast groups.
