Examples with Bandwidth org.onlab.util.Bandwidth used on opensource projects

Example 1 with Bandwidth

use of org.onlab.util.Bandwidth in project onos by opennetworkinglab.

the class OpticalPathProvisioner method setupConnectivity.

/*

     * over packet-optical multi-layer infrastructure.
     *
     * Functionality-wise this is effectively submitting Packet-Optical
     * multi-layer P2P Intent.
     *
     * It computes multi-layer path meeting specified constraint,
     * and calls setupPath.
