摘要:
The system is for combining and transmitting data fragments for multiple customer ports sent over a first packet-switched computer network to a trunk network and redistributed over a second packet-switched computer network, each customer port having a preselected bandwidth designation. The system provides a First-In First-Out (FIFO) register to capture incoming data bits from each customer port in parallel and speeds equal to or greater than 1 Gbps, providing selectors connected to the FIFO outputs. Each selector is capable of mapping individual incoming data bits from different customer ports and combining them into the same trunk fragments. Each trunk fragment receives data bits from customer ports. by selector values for each customer. The filling sequence for each fragment is repeated until sufficient trunk fragments form a filled trunk frame.

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.

The invention provides a method of forming s custom data packet for a point-to-point trunk network, the method comprising the steps of providing a First-In First-Out (FIFO) register to capture data packets transmitted via a packet-switched computer network at speeds equal to or greater than 1 Gbps, the packet switched data packets having a packet switched header and a packet switched frame check sequence (FCS), providing selectors connected to the FIFO outputs, each selector receiving a packet-switched data packet and stripping out the packet-switched header and replacing if with a mini-header and filling each stripped data packet with 1 to 1,500 bytes of customer data to transform each data packet to a high payload data packet, replacing the packet-switched FCS with a mini-FCS. Sending each high payload data packet across the point-to-point trunk network having a reduced latency of less-than 1 microsecond for roundtrip transmission and recreating the standard packet-switched data packet based on the mini-header and mini-FCS.
