Abstract: A technique includes selecting a first device from a plurality of interconnected devices to form a root of a power tree connecting the interconnected devices and allocating power among neighbors of the interconnected devices in a direction along the tree away from the root. The technique includes determining whether at least one of the interconnected devices needs power after the allocation of power among the neighbors and selectively further allocating power among the neighbors in a direction along the tree toward the root based on the determination.

Abstract: Traffic control can be provided across a Layer 2-Layer 3 boundary in a software defined network. A network controller can receive information related to a number of conditions in a software defined network (SDN) from a number of network devices. The network controller can provide network traffic control across a Layer 2-Layer 3 boundary in the SDN based on the received information.

Abstract: A method and system for selecting a data compression technique for data transfer through a data network is provided. During call setup, information is gathered from the network infrastructure by receiving feedback from smart network devices, reviewing calls logs, or by accessing a network topology database, and the information can then be used to select a desired compression technique. During a call, a media terminating end device or a call control server will monitor call connection performance specific to the data transfer pathway used for the call connection, and may adjust the data compression to conform with the performance that the connection is providing at any given moment. Performance parameters such as delay, jitter, and compression ratios can be measured in real-time for a call to determine if a change in compression is deemed beneficial. In this manner, the compression method can be chosen based on real time network performance.

Abstract: Power is automatically allocated among a plurality of network switches, such as a plurality of stackable switches. In one embodiment, one device in the network is designated as a “master” device which controls the power allocation for all of the switches. In another embodiment, a distributed algorithm is used, in which each device uses power allocation decision logic to formulate a mutually agreed-upon power allocation. Power from multiple power-granting devices may be consolidated to provide aggregated power to one or more power-needing devices.

Abstract: A dynamic network tuner establishes fluid, continuous, and automatic correlation between the extent and/or degree of a networking device's functionality, on the one hand, and the network-related performance (i.e., network data traffic and/or network application performance), on the other. The dynamic network tuner can be embodied as a discrete device ready for installation into a host network. Preferably, such (and like) tuner embodiments are integrated into a network to automatically correlate, according to user-predefined parameters, the network's performance with the operation within the network of specifically-targeted, performance-altering networking devices, such as network security devices, or more preferably and particularly, intrusion prevention devices.
