Method and apparatus for documenting network paths
Methods and apparatus for documenting network path connectivity are described that allow a network management system/revision management system (NMS/RMS) to determine what equipment and ports support a network path by interrupting and restoring Power-over-Ethernet (PoE) service on the network path.

Dynamic latency-based rerouting
A switch creates and dynamically updates a latency map of a network to adjust routing of flows. Further, the network is monitored to detect latency issues and trigger a dynamic adjustment of routing based on the latency map. In this manner, a flow can be routed along a route (i.e., a faster route) that provides less latency than other available routes. The latency map can be generated based on latency probe packets that are issued from and returned to the source switch. By evaluating many such latent probe packets that have traveled along many available routes (e.g., corresponding to various ports of the switch), the switch or associated administrative logic can dynamically adjust the latency map to updated latency information of available routes. Therefore, responsive to a trigger, the source switch can dynamically adjust the routing of a flow based on latency issues discerned from the network. |

Multi-output DC-DC converter
A DC-to-DC converter generates multiple outputs from a single input supply using a single inductor. The inductor current can be changed rapidly by connecting the input voltage in either direction across the inductor using switches A to F. In use, current flows from the input supply through the inductor to an output during a charge phase, then current flows from ground through the inductor to the output in a discharge phase. The level of inductor current at the end of the discharge phase is stored. Before the next charge phase for the same output, the input supply is connected across the inductor in a slew phase to bring the inductor current to the stored level. This reduces crosstalk between outputs having different power requirements. Variable frequency noise in the converter is reduced by giving each output the same total time (slew phase+charge phase+discharge phase). |
