Self-healing data transmission system and method to achieve deterministic and lower latency

摘要

The invention provides a method of simulcasting data fragments sent over a first packet-switched computer network to a trunk network and redistributed over a second packet-switched computer network. A method is provided comprising the steps of providing a trunk network including multiple links including an RF link and a fiber link, wherein all the transmission links transmit data packets to a receiver which will redistribute the earliest data packets with a matching frame check sequence (FCS) over the second packet switched computer network. The method provides for a sender for adding an incremental sender sequence number and sender FCS to the data packets, creating a sender data packet. Transmitting a sender data packet, simulcast over the transmission links, receiving, by a receiver, via the fastest links which may drop or change some bits unintentionally, a sender data packet and receiving, by the receiver, via slower links which are unlikely to drop or change some bits unintentionally, a sender data packet. The method provides for checking, by the receiver, a receiver calculated FCS of the received sender data packet and comparing them to the sender FCS that was added by the sender. Transmitting over the second packet-switched computer network, the first sender data packet with the next sequence number increment after the incremental sender sequence number and verifying sender FCS, verifying, by the receiver, the sender data packets and identifying, by the receiver, a gap between sender data packets, queueing up verified sender data packets when there is a gap in the verified sender data packets and sending all verified sender data packets in sequence order, once the gap is filled by any transmission link.

1. A method of simulcasting data fragments sent over a first packet-switched computer network to a trunk network and redistributed over a second packet-switched computer network, the method comprising the steps of:
providing a trunk network including multiple links including an RF link and a fiber link, wherein the links transmit data packets to a receiver, which will redistribute the first data packet that reaches the receiver first, redistributing the first data packet with a matching frame check sequence (FCS) over the second packet switched computer network; providing a sender for adding an incremental sender sequence number and sender FCS to the data packets, the sender creating a sender data packet and transmitting the sender data packet as a simulcast over the links; receiving, by a receiver, via the RF link a sender data packet; receiving, by the receiver, via the fiber link, a sender data packet; checking, by the receiver, a receiver calculated FCS of the received sender data packet and comparing the receiver calculated FCS to the sender FCS that was added by the sender; transmitting over the second packet-switched computer network, the first sender data packet with the next sequence number increment after the incremental sender sequence number and verifying the sender FCS; verifying, by the receiver, the sender data packets; identifying, by the receiver, a gap between sender data packets; queueing up verified sender data packets when there is a gap in the verified sender data packets; and sending all verified sender data packets in sequence order, once the gap is filled by any link.
