Request multiplexing
The embodiments provide request multiplexing whereby a server receiving a first request for content clones and issues the cloned request to an origin to initiate retrieval of the content.

Admission control in a packet network
In embodiments of the invention when a session request is received the value assigned to that session is compared to present congestion costs in the network at the present time. If the value of the session exceeds the cost then the session is accepted; otherwise it is rejected. It is possible to show mathematically that, provided this strategy is used for all session requests, then, when demand exceeds supply for a given resource, the congestion measurement for that resource rises to become equal to its shadow price. Here, in a model of a capacity constrained network, the shadow price of a capacity constraint is the cost to other users of using one unit of capacity. Congestion measurements can therefore be used to provide a “cost” (to other users) of admitting the flow to the network, which can then be compared against the “value” (to the network operator) of admitting the flow during the admission control evaluation. Additionally, this “cost” vs. “value” comparison can be used for path selection, as well as any other resource management decision. For example, in particularly preferred embodiments a session is not only admitted based upon the cost value comparison, but is also assigned to a particular path which maximizes value minus cost. |

Multiplexed sigma-delta analog-to-digital converter
A sigma-delta ADC circuit with an analog loop filter circuit can be multiplexed between different inputs by flushing the memory of the analog loop filter integrators and the digital decimation filter and filling it with new data for the current input. However, filling the memory can be slow with respect to the sampling frequency because the information about past history has to be built up before meaningful output data can be generated. Thus, the multiplexing rate between channels using a sigma-delta ADC circuit can be slowed by such memory flushing. A multiplexed sigma-delta ADC circuit is described that can overcome these problems so as to be able to support cycle-by-cycle sampling of multiple channels. These techniques can provide a fast sigma-delta analog-to-digital converter (ADC) circuit that is small in area and that can multiplex over a number of channels dynamically. |

Connector and connector assembly with rockable lever to assist with mating and separating
A first connector has the rockable lever for engaging with a second connector. The lever has a working part, the operating part, and the regulating part. When a second connector is pressed downward toward the first connector, the working part is pressed by the second connector. As a result, the lever rocks and the regulating part regulates the upward movement of the second connector. At this time, the operating part moves upward. When an operator subsequently presses the operating part downward, the lever rocks in the opposite direction, and the regulating part allows the second connector to move upward. At this time, the first working part moves upward thus pressing the second connector upward. |

Electric connector and manufacturing method of the same
By a simple configuration, contact members can be well retained with a housing in a mutually opposed state, and productivity can be improved. When the contact members in the mutually opposed state are to be attached to the housing, a contact retainer prepared by molding in advance is used by disposing the contact retainer in part of the contact opposed region. As a result, the contact members are stably retained in the mutually opposed state even in injection molding molds. Even in a case in which the contact members normally cannot be retained in the mutually opposed state in the injection molding molds, the housing and the contact members can be integrally molded by well retaining the contact members in the mutually opposed state by using the contact retainer and a contact retainer auxiliary and executing an injection molding process. |
