摘要： In one embodiment, a method includes accessing a first utilization value, accessing a second utilization value, defining a third utilization value, and sending to a first switching portion of a distributed network switch a deactivate signal in response to the third utilization value. The first utilization value is associated with the first switching portion of the distributed network switch. The second utilization value is associated with a second switching portion of the distributed network switch. The third utilization value is associated with the second switching portion of the distributed network switch and is based on the first utilization parameter and the second utilization parameter. The first switching portion of the distributed network switch ceases communication within the distributed network switch in response to the deactivate signal.

摘要： A front-to-back cooling system allows cooling of an apparatus containing two orthogonal sets of modules. Each set of modules is independently cooled. A vertical set of modules is cooled with vertical air flow across the modules that enters from a front of the apparatus and exhausts from a back of the apparatus. A horizontal set of modules is cooled with horizontal front-to-back air flow. When the horizontal set of modules is at the front of the apparatus, a plenum extending exterior to the vertical set of modules allows exhausting horizontally flowing air to the rear of the apparatus. When the horizontal set of modules is at the rear of the apparatus, a plenum extending exterior to the vertical set of modules allows moving air from the front of the apparatus to a chamber holding the horizontal modules.

摘要： In some embodiments, an apparatus includes a switch fabric having at least a first switch stage and a second switch stage, an edge device operatively coupled to the switch fabric and a management module. The edge device is configured to send a first portion of a data stream to the switch fabric such that the first portion of the data stream is received at a queue of the second switch stage of the switch fabric via the first switch stage of the switch fabric. The management module is configured to send a flow control signal configured to trigger the edge device to suspend transmission of a second portion of the data stream when a congestion level of the queue of the second switch stage of the switch fabric satisfies a condition in response to the first portion of the data stream being received at the queue.

摘要： A data processing unit includes a chassis configured to contain a line card. The chassis defines, at least in part, a portion of a first flow pathway and a portion of a second flow pathway. The chassis is configured such that a first portion of a gas can flow within the first flow pathway between an intake region and the first end portion of the line card such that the first portion of the gas flows across a first end portion of the line card in a first direction. The chassis is configured such that a second portion of the gas can flow within the second flow pathway between the intake region and a second end portion of the line card such that the second portion of the gas flows across the second end portion of the line card in a second direction opposite the first direction.
