Patent US 9,219,684

New communication system with packet's retransmission elements that do not use and do not depend on any routing protocol provides definite mechanisms to deliver packets from sender to receiver. Packet's retransmission elements are no longer in charge for calculating and maintaining routing tables in order to make decision regarding packet forwarding from ingress port to egress port. Each packet besides data contains set of instructions that presents complete path description from sender to receiver and rules of packet's processing on its way depending on various network metrics. The set of instructions is devised to be executed or interpreted by each network element that packet passing through. The outcome of instructions execution provides decision regarding packet forwarding and transformation. In order to provide information for path calculation and rules of packet processing there are centralized services—Network map, Pathfinder, Name registrar and Network policy.
