Elements of the interface description file are identified according to a template file responsive to the parsing thereof, and an output file that includes human-readable documentation for the computing interface is automatically generated from the elements identified in the interface description file. Related devices and computer program products are also discussed.

Abstract: A packet is communicated between a first node and a second node by assigning a plurality of packet fragments to a plurality of communication links connecting the first node and the second node, respectively, such that respective sizes of the plurality of packet fragments are based on respective bandwidths of the plurality of communication links. The plurality of packet fragments is transmitted on the plurality of communication links from the first node to the second node. The plurality of packet fragments is then reassembled at the second node upon receipt.

Abstract: A control node of a communication network is operated at a packet bandwidth determined according to observations of performance metrics of the network at the control point. These performance metrics may be one or more of throughput, average fetch time and packet loss. The control node is operated so as to set a control bandwidth to corresponding resonance points of the performance metrics. The resonance points are determined by scanning across a range of control bandwidths, until one or more of the performance metrics is/are optimized. The packet bandwidth is set by varying an inter-packet delay time over selected communication links at the control node.

Abstract: Predictions of congestion conditions for a traffic stream in a communication network are applied to modify an initial congestion window size for the traffic stream; and dynamic bandwidth control is thereafter applied to the traffic stream. This dynamic bandwidth control may include modulating inter-packet bandwidths of the traffic stream according to a capacity of a bottleneck in a communication path through which the traffic stream passes in the communication network. The predictions of congestion conditions may be based on monitoring packet losses and/or round trip times within the communication network for a selected period of time. The monitoring may be performed on at least one of a traffic stream-by traffic stream basis, a connection-by-connection basis, a link-by-link basis, or a destination-by-destination basis.

The display and the optics can be housed in a housing. Integrated operational controls can be located on the housing for controlling the operation of the viewer.

Abstract: A distributed network monitoring system includes a central monitoring device configured to store global configuration information for all monitoring devices which make up the distributed system, and one or more remote monitoring devices configured to receive, in response to a request therefor, at least a portion of the configuration information from the central monitoring device. The remote monitoring devices and the central monitoring device may be communicatively coupled through respective secure communications paths (e.g., SSH communication tunnels) established on an as-needed basis by secure communication tunnel processes executing at the central monitoring device and remote monitoring devices. The central network monitoring device may further include a configuration servlet configured to provide requested portions of the configuration information to the one or more remote monitoring devices.

Abstract: Congestion within a communication is controlled by rate limiting packet transmissions over selected communication links within the network and modulating the rate limiting according to buffer occupancies at control nodes within the network. Preferably, though not necessarily, the rate limiting of the packet transmissions is performed at an aggregate level for all traffic streams utilizing the selected communication links. The rate limiting may also be performed dynamically in response to measured network performance metrics; such as the throughput of the selected communication links input to the control points and/or the buffer occupancy level at the control points. The network performance metrics may be measured according to at least one of: a moving average of the measured quantity, a standard average of the measured quantity, or another filtered average of the measured quantity.

Abstract: End-to-end packet losses of one or more traffic streams transmitted across a congested network may be reduced by setting the bandwidths of the corresponding traffic streams at critical values thereof at one or more control points along the network topology. The critical value of the bandwidths may be determined by monitoring buffer occupancy at the control point(s). Buffer occupancy may be determined by periodically sweeping down from a maximum bandwidth value according to a monotonically decaying exponential function.

Abstract: An ATM information system processes information at the frame level using a processor including a device driver; a system memory and an adapter for sorting data cells into partially completed frames stored in the system memory using control information provided by the device driver. A controller in the adapter determines when an end of frame indication is received in a cell and updates a pointer in system memory for a completed frame list to a recently completed frame. The device driver processes frames in a completed frame list according a priority of the list. The device driver processing is independent of the sorting and storing of completed frames received in the system memory which improves the performance of the driver and the ability to handle delay sensitive traffic.
