1. A bimodal burst-switching network comprising a plurality of edge nodes each having an edge controller, said plurality of edge nodes connecting to at least one core node where at least one edge node:

  • determines proximity of the edge node to a selected core node;

    selects a first-mode of burst transfer when said proximity is within a predefined proximity threshold; and

    selects a second-mode of burst transfer when said proximity is beyond said predefined proximity threshold;

    wherein a controller of an outbound port of an edge node determined to be within said predefined proximity threshold from said selected core node;

    forms data bursts;

    sends descriptors of said data bursts to a core-node controller of said selected core node;

    receives burst-transmission schedules from said core-node controller; and

    transmits said data bursts to said selected core node according to said burst-transmission schedules.
