  • Patent number: 10601509
    Abstract: In described embodiments, a relatively optimum, ultra-low latency communication path with communication links operating in accordance herein provide for graded service in a near optimal, ultra-low latency communication system between points A and B. Points A and B are separated geographically over a relatively long distance where the curvature of the earth affects a direct path. Unlike typical systems, to provide the graded service in ultra-low latency networks, the service provider adds delay, or other service degradation, to one or more user connections, which is provided at greater implementation expense (e.g., higher cost to the service provider) in order to provide a lower fee service (e.g., lower cost to the service user) for certain users of the ultra-low latency network.
