Abstract: This disclosure describes techniques for providing application assurance by validating expected packet flows for an application against a model of a network that is to transport the expected packet flows. For example, a method includes obtaining, by an application assurance system, a flow definition that describes a packet flow for an application; determining, by the application assurance system by querying a network model of a network system that transports packet flows for applications, using the flow definition, a set of network nodes and links of the network system that are expected to transport or process the packet flow for the application; obtaining, by the application assurance system, an indication that a network node or link, from the set of network nodes and links, is in an operational state that could affect performance of the application; and in response to obtaining the indication, by the application assurance system, outputting an alert.

Abstract: An oil control device inhibits the flow of oil along a shaft (8) rotating about an axis. The oil control device comprises an annular body (19) for rotation with said shaft (8) and includes a first face (30) extending generally radially from said axis. A second radially outer circumferential surface (40) is provided, extending generally axially. An oil slinging groove (32) extends into said body (19) and has a mouth (37) defined between a first circumferentially extending rim (38) and a second circumferentially extending rim (39). The second rim (39) is spaced both radially and axially from the first rim (38). The groove (32) is defined at least in part by a wall (34) which meets the first rim (38) at an acute angle to a radial plane. The groove (32) is also defined at least in part by a wall (35) which meets the second rim (39) at an acute angle to the direction of the axis.

Abstract: Inter-Symbol Interference is measured in fibre-optic communications systems by using the statistically balanced nature of the data being communicated and correlating a received data signal with a time-delayed version of the data signal to obtain an error signal. The error signal drives an adaptive equaliser to achieve channel equalisation.

Abstract: In the field of optical communications, a number of techniques are known for channel equalisation. However, these techniques are, for various different technical and/or economic reasons, unsuitable for application in relation to optical communications at a data rate of 10 Gbps. Consequently, the present invention provides a dithered linear search algorithm adapted to change tap weights (45, 75) of a filter (15) in accordance with a heuristic tap modification scheme.

Abstract: A round of negotiation for an item is initiated between a plurality of bidders at a plurality of client nodes and a host processing node. A price bid for the item is received from each of the plurality of bidders. At least one negotiation parameter is received from at least one of the plurality of bidders. The negotiation parameter is associated with the item. A total cost value is determined based on an active negotiation term, the price bid, and the negotiation parameter for each of the plurality of bidders.

Abstract: A data rate determination apparatus includes an edge detection and clock generation circuit for receiving an input bit stream. The edge detection and clock generation circuit generates a pulse for each edge detected in the input bit stream. The pulses are passed to a programmable re-triggerable monostable multivibrator circuit coupled to a binary counter, which counts how many pulses are received within a time period determined by the number of pulses received at a rate higher than a predetermined rate. The binary counter is coupled to a Gray code counter coupled to a processing unit. The processing unit uses different counts that are accumulated over different sampling periods with different predetermined rates to establish statistical data, which can be compared to known data for different data rate standards or formats.
