1. A computer-implemented method for determining feasibility of establishing a connection in a mesh network including a plurality of bidirectional links with different capacities, and a plurality of switching devices, comprising:

  • (a) monitoring, on a computing device, utilization of bidirectional links connecting the plurality of switching devices;

    (b) for both directions of each of the links, determining, on the computing device, a predicted utilization of the link in the direction based on the utilization of the link monitored in (a);

    for each of a plurality of rings in the mesh network;

    (c) determining, on the computing device, a clockwise bottleneck link in the ring;

    (d) determining, on the computing device, a counterclockwise bottleneck link in the ring;

    (e) determining, on the computing device, an available bandwidth of the ring based on the clockwise bottleneck link and the counterclockwise bottleneck link;

    (f) identifying a set of rings from the plurality of rings to be utilized to provide a requested dedicated network connection between at least two locations; and

    (g) determining whether the requested dedicated network connection is feasible based on the available bandwidth determined in (e).
