Improved reliability and reduced delays and packet losses of Internet media transmissions over packet switching networks such as Internet and Intranet is achieved by replicating a sent message/information packet(s) from one or more source computers connected to the network into two or more replicas of one or more of the packets of the sent message. Each of the replicas is then directed through a different route through the network to one or more destination computers. In one embodiment, each of the routes is determined so that the routes have the least number of routers and access points in common. Since the replicas are redundant, losses and delays of some of the replicas is not fatal to assemble the packet sequence at the destination(s). Thus, the destination computer can assemble the sent message/information packet from received replicas in a more complete and faster manner. Redundant replicas that are received can be ignored and/or discarded at the destination computer.

DETAILED DESCRIPTION This invention improves the reliability and reduces the delays and packet losses of Internet media transmissions over packet switching networks such as Internet and Intranet.
The invention replicates a sent message/information packets from one or more source computers connected to the network into one or more replicas of one or more of the packets of the sent message.
Each of the replicas is then directed through a different route through the network to one or more destination computers.
In a preferred embodiment, the replication and routing is done randomly and each of the routes is determined so that the routes have the least number of routers and access points in common.
Since the replicas are redundant, losses and delays of some of the replicas is not fatal to assemble the packet sequence at the destination(s).
Thus, the destination computer can assemble the sent message/information packet from received replicas in a more complete and faster manner.
Redundant replicas that are received can be ignored and/or discarded at the destination computer.
