摘要:
A packet-based traffic switching system with error detection and correction without taking the system offline. The system tests offline paths without interfering with other online paths. Also, the system tests online paths even while no data cell traffic is sent over the paths. The system responds to the addition or removal of paths or path components without interrupting cell traffic. The system detects and selectively flushes defective paths without impacting paths that are working properly. The system initializes new switching fabrics automatically without using software to set values. Thus, the system tests online paths and corrects errors without going offline.
摘要:
A system for efficiently reassembling packets from cells received on independent switching fabrics according to a serial high speed interface (HSI) protocol. The system includes redundancy in that fabrics may be removed by skipping the fabrics in striping and reassembly sequences. When fabrics are added, the fabrics are included in the striping and reassembly sequences. The system is efficient due in part to in-order transmission of cells serially across multiple fabrics. Full fabric bandwidth is thereby utilized without reordering overhead. Since packets are striped across all available fabrics, load is balanced across the fabrics.

A system for efficiently sending cells in-order to independent switching fabrics according to a serial high speed interface (HSI) protocol. The system includes redundancy in that fabrics may be removed by deleting the fabrics from striping and reassembly sequences. When fabrics are added, the fabrics are added to the striping and reassembly sequences. The system is efficient due in part to in-order transmission of cells serially across multiple fabrics. Full fabric bandwidth is thereby utilized without reordering overhead. Since packets are striped across all available fabrics, load is balanced across the fabrics.

A traffic control system and method with flow control aggregation. The system includes a switching fabric and an ingress module. The switching fabric includes read counters that are associated with a plurality of queues. The read counters represent an aggregated number of cells dequeued from respective queues since a previous flow control message (FCM) was sent to the ingress module. The read counters are reset when a FCM is created. The ingress module includes write counters that are associated with the queues. The write counters are incremented each time a cell is sent to the respective queues. The write counters are decremented in accordance with the FCM when the FCM is received. Also, read counters for one or more queues are aggregated into a single FCM.

A traffic forwarding system that uses a multicast start-of-packet (SOP) pointer to enqueue a multicast packet in packet queues. The system receives cells, assigns pointers to the cells, and stores the received cells in memory. The system assigns multicast SOP pointers to multicast SOP cells. The system reassembles cells into packets and enqueues the packets in packet queues for forwarding. A multicast packet is enqueued in a plurality of packet queues. The memory in which the multicast packet is stored is released after the multicast packet is dequeued from each of the plurality of packet queues.

A high-speed parallel interface for communicating data between integrated circuits is disclosed. The interface is implemented by a transmitter and receiver pair and a single-ended parallel interconnect bus coupling to the transmitter and receiver pair. As opposed to transmitting small swing signals over differential signal lines, the transmitter transmits data to the receiver at full swing over the single-ended parallel interconnect bus. The invention can be implemented with simple CMOS circuitry that does not consume large die area. Accordingly, many link interfaces can be implemented on a single chip to provide a large data bandwidth.

A high-speed parallel interface for communicating data between integrated circuits is disclosed. In one embodiment, the transmitter controller accepts 40-bit wide data every 167 Mhz clock cycle, the receiver controller delivers 40-bit wide data every 167 Mhz clock cycle, and the interconnect bus transmits 10-bit wide data at every transition of a 333 Mhz clock cycle. In another embodiment, the transmitter controller accepts 32-bit wide data every 167 Mhz clock cycle, the receiver controller delivers 32-bit wide data every 167 Mhz clock cycle, and the interconnect bus of this embodiment transmits 8-bit wide data at every transition of a 333 Mhz clock cycle. Output pins of the transmitter interface can be connected to any input pins of the receiver interface. Furthermore, the high-speed parallel interface does not require a fixed phase relationship between the receiver's internal clock(s) and the bus clock signal.
摘要:
A two stage rate shaping and scheduling system and method is implemented to control the flow of traffic to at least one output interface. The system and method involves initially queuing incoming packets into type-specific queues and applying individual rate shaping rules to each queue. A first stage arbitration is performed to determine how traffic is queued from the type-specific queues to interface-specific queues. Packets that win arbitration and pass the applied rate shaping rules are queued in interface-specific queues. Rate shaping rules are applied to the interface-specific queues. The interface-specific queues are further distinguished by priority and priority-specific and interface-specific rate shaping rules are applied to each queue. A second stage arbitration is performed to determine how different priority traffic that is targeting the same output interface is dequeued in response to interface-specific requests.

A method for cleansing a desired skin surface, and a device therefor, can include a base to house a jar for the cleansing liquid, a jar for the removed liquid and debris, a pump to deliver the cleansing liquid to a wand applicator, and a pump to suction the cleansing liquid and debris removed from the desired skin surface. The two pumps can be driven by separate motors to allow a user to separately control the amount of liquid dispensed and the magnitude of the suction force applied. The device can also include an infusion enhancer that assists in the opening of the pores of the desired skin surface or by tightening the desired skin surface. The device can further include a self-cleaning tip that allows a cleaning solution to be immediately recycled through the system into the jar for the removed liquid and debris.

The present disclosure relates to a ladder-mountable storage device for storing and retractably deploying a flag. The flag can be displayed on the end of a ladder to warn onlookers. If used on the end of a ladder extending from a vehicle, the flag warns drivers to keep a safe distance, for example. The ladder-mountable storage device can also be attached to the top of ladders placed alongside buildings and other structures.
