摘要： A device includes a memory, flow table logic, sampling logic, and a processing unit. The memory is configured to store a flow table that stores, as a number of entries, statistics regarding a number of data flows. The flow table logic is configured to generate records corresponding to data flows for which entries are created in the flow table or removed from the flow table. The sampling logic is configured to select one of the data flows for sampling and sample initial data units for the one of the data flows. The processing unit is configured to receive the records generated by the flow table logic, receive the initial data units sampled by the sampling logic, analyze the initial data units to generate analysis results, correlate the records and the analysis results associated with a same one of the data flows, and store the correlated records and analysis results.

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.
