Abstract:
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.
