Abstract
A system and method are described for synchronizing store-and-forward networks and for scheduling and transmitting continuous, periodic, predictable, time-sensitive, or urgent information such as real-time and high-priority messages over those networks. This enables packet-, cell-, and/or frame-based networks to thereby efficiently switch voice, video, streaming, and other real-time or high-priority data at the layer one or physical level, thus ensuring that the delivery of selected information can be made fast, on-time, immediate, non-blocked, non-congested, loss-less, jitter-free, and have guaranteed delivery, and guaranteed quality of service.
Claims54
A method for performing time-scheduled packet transfer comprising the steps of:
- establishing a first packet transfer path between a source network element and a destination network element;
- determining one or more packet transfer times between said source network element and said destination network element for transferring one or more packets;
- and
- transferring said one or more packets from said source network element to said destination network element over said first packet transfer path in accordance with said one or more packet transfer times.
A method for performing synchronized packet-oriented transfer, comprising the steps of:
- establishing a first transmission path between a source and a departure router;
- sending from said source to said departure router a request for a time sensitive data transmission from said source to a receiver;
- locating a mid-destination router and a second transmission path from said departure router to said mid-destination router;
- locating a final destination router and a third transmission path from said mid-destination router to a final destination router;
- locating said receiver and a fourth transmission path from said final destination router to said receiver;
- negotiating a reservation schedule between said departure router, said mid-destination router, and said final-destination router;
- transmitting time sensitive data from said source to said receiver in accordance with said reservation schedule, said first transmission path, said second transmission path, said third transmission path, and said fourth transmission path.
A system for routing information through a network of switches, comprising:
- a first network element adapted for communication in accordance with layer one switching;
- a second network element adapted for communication in accordance with layer one switching;
- a data source, said data source adapted for communication with said first network element;
- a data receiver, said data receiver adapted for communication with said second network element;
- a plurality of network elements between said first network element and said second network element, said plurality of network elements adapted for communication in accordance with layer one switching;
- and
- a transmission path between said data source and said data receiver, said transmission path adapted for transmission of data from said data source to said data receiver in accordance with layer one switching.
