摘要:
In accordance with one or more embodiments of the present invention, a method and system for providing combined processing of cell traffic and packet traffic is described. For a communication device, the improved system provides a series of inputs on a single line card for processing both ATM traffic (e.g., native ATM or encapsulated packets) and packet traffic. The system receives the cell traffic and packet traffic, then converts them into a common form. The converted traffic traverses the fabric, then the system reconstitutes the converted traffic into its original form. The system provides output as ATM traffic or packet traffic, as originally received.

A gas supply system is disclosed. The gas supply system includes a housing, a spool, a gas tube, at least one opening, a retract mechanism and a holding member. The spool is configured within the housing. The gas tube is retractably wound on the spool and includes a first end portion and a second end portion capable of being connected to a gas supply and a nasal cannula respectively. The at least one opening is configured on the housing for enabling at least one of the first end portion and the second end portion of the gas tube to extend out of the housing. The retract mechanism is configured in the housing and is capable of retracting a portion of the gas tube extended out of the housing. The holding member extends from the housing and enables the gas supply system to be removably mounted on a supporting member.

A scheduling device for use in a packet-switched network, belonging to the class of non-work conserving or idling weighted round robin (WRR) arbiters, assigns a packet stream slots in a fixed-length time division multiple access (TDMA) frame by selecting free slots which are closest to ideal slot positions that would, if assigned, eliminate jitter or cell delay variation. The scheduler is able to simultaneously determine if a new constant bit rate connection requiring a predetermined bandwidth conforms to a leaky bucket or GCRA algorithm characterized by a peak packet or cell emission interval T=1/PCR and a packet or cell delay variation time, CDVT, i.e., whether the new connection is GCRA (T, CDVT) conformant. This determination is made by comparing the quantity ME+ML against the CDVT, where ME corresponds to the maximum time or distance by which any assigned slot is earlier than a corresponding ideal slot and ML corresponds to a maximum time or distance by which any assigned slot is later than a corresponding ideal slot. The scheduler can thus also carry out connection admission control (CAC) functions in an ATM network switch.

In a real-time auction user interface display, the user may select to participate in multiple auctions simultaneously in which case the user interface divides the display screen into different areas and displays information about an ongoing auction in each of the different display areas. The user may select which auction to display in which display area. Each of the auction display areas are updated independently based on information provided by multiple disparately-located auctions.

A system and method for adaptively assigning queue service weights to an ATM traffic management controller in order to reduce service weight update calculations. The implementation of a fair weighted queuing scheme on a network is divided into two functions: queue arbitration; and queue weight configuration. Queue arbitration is performed via a virtual time-stamped fair queuing algorithm. The queue weight configuration is performed via a reconfigurable weighted fair queuing controller wherein bandwidth requirements are calculated in response to connection setup and release values.

A headset is constructed to generate an acoustically distinct speech signal in a noisy acoustic environment. The headset positions a pair of spaced-apart microphones near a user's mouth. The microphones each receive the user's speech, and also receive acoustic environmental noise. The microphone signals, which have both a noise and information component, are received into a separation process. The separation process generates a speech signal that has a substantial reduced noise component. The speech signal is then processed for transmission. In one example, the transmission process includes sending the speech signal to a local control module using a Bluetooth radio.

Techniques for bandwidth management and flow control on a resilient packet ring (RPR) network is described. The RPR requires allocation and guarantee of a bandwidth for each channel between two nodes on the ring. The bandwidth is managed by shaping traffic on a channel at the source by using a bandwidth allocation factor calculated at each node. The bandwidth allocation factor, which is communicated to other nodes, is calculated by using a recursive nonlinear function of the transit buffer size.

A live auction or other sales transaction permits sellers to dynamically participate from remote locations. The remotely-located seller receives a simulcast of the auction in progress and is able to at any time indicate to the auctioneer an approval to sell an item on the block at the current high bid price. The remote seller may also send a counteroffer to the current high bidder, “if” the sale or reject the high bid to result in a no sale. The computer system detects when the remote seller is temporarily inactive to allow the auctioneer to proceed as if the seller were not present. The remote seller feature can be used on sales with remote buyers, sales with all buyers located at the same location as the goods being offered, or a combination.
摘要:
A device and algorithm for fairly allocating available bandwidth between contending connections at a contention point in a data network. The allocation is based on global queue size at the contention point and a weighted value assigned to the data traffic. The device and algorithm find particular application in an ATM network which supports the available bit rate (ABR) service category.
