摘要:
Network traffic information from multiple sources, at multiple time scales, and at multiple levels of detail are integrated so that users may more easily identify relevant network information. The network monitoring system stores and manipulates low-level and higher-level network traffic data separately to enable efficient data collection and storage. Packet traffic data is collected, stored, and analyzed at multiple locations. The network monitoring locations communicate summary and aggregate data to central modules, which combine this data to provide an end-to-end description of network traffic at coarser time scales. The network monitoring system enables users to zoom in on high-level, coarse time scale network performance data to one or more lower levels of network performance data at finer time scales. When high-level network performance data of interest is selected, corresponding low-level network performance data is retrieved from the appropriate distributed network monitoring locations to provide additional detailed information.

摘要:
Applicant's high-speed input/output signaling mechanism makes exclusive use of one or more processors (CPU) for polling. Device-bound perpetual polling is initiated neither by the device nor by the processing application: it takes place independently from them, on a CPU exclusively reserved for that task. Another aspect of the present invention is that communication with the I/O device is through the use of “DMA descriptors” that reside in the main memory of the system. In an alternative embodiment, a special purpose device that lacks the full architecture of a typical CPU may play the role of the exclusive polling CPU.
