Abstract: A method and system for deterministic network bandwidth aware multicast flow provisioning. In addressing network bandwidth oversubscription, embodiments disclosed herein propose a solution through which an intelligent and deterministic methodology may be implemented for provisioning network multicast traffic flows in order to minimize, if not eliminate, network bandwidth oversubscription. To that end, embodiments disclosed herein employ a centralized network controller configured to obtain a range of aggregated network state pertinent to deterministic, network bandwidth aware multicast traffic flow programming. Said aggregated network state may be collected through a number of logical agents dispersed throughout a network, and may include network device connectivity, network path or link bandwidth capacity, and network multicast status information.

Abstract: Devices and methods for bone fixation including a bone fixation system including a bone plate or intervertebral spacer including a plurality of apertures dimensioned to receive bone fasteners and at least one polymeric element capable of transitioning from a solid state to a flowable state. The polymeric element transitions to a flowable state as a result of exposure to ultrasonic vibration. The polymeric element is placed on the bone plate or intervertebral spacer adjacent a fastener in an aperture and acts to prevent rotational and/or translational movement of the fastener relative to the bone plate or intervertebral spacer.
