摘要： A method of controlling data packet congestion in a data packet network comprises determining a reference flow condition that results in data packet congestion at a node of a data packet network, and identifying a data packet flow having a flow condition substantially equal to the reference flow condition. For such an identified data packet flow the following actions are taken causing a data packet to be dropped from the identified data packet flow, allowing a predetermined number of data packets from the identified data packet flow to proceed, and dropping data packets from the identified data packet flow subsequent to the predetermined number of data packets, until the packets that were not dropped have been delivered to the egress ports of the network.

摘要： A multi-path network for use in a bridge, switch, router, hub or the like, includes a plurality of network ports; a plurality of network elements; and a plurality of network links interconnecting the network elements and the network ports, for transporting data packets. Each network element has a fault monitor for detecting faults on the network links to which the network element is connected, a plurality of dynamically selectable output ports and output port selection mechanism. Each network element also being adapted to communicate the existence of a fault back to one or more other network elements so that network elements connected to the faulty network link can be bypassed, and each network element being adapted to update the output port selection mechanism when communication of the existence of a fault is received so that only those output ports which ensure the faulty network link is bypassed are dynamically selectable. Also, a method of managing faults in a multi-path network utilizes a similar methodology to insure that identified faults are avoided.

摘要： A data processing system comprises a first clock domain having a first clock rate, a second clock domain having a second clock rate, and a data path operable to transfer data items from the first clock domain to the second clock domain. The data path comprises a buffer having an input for receiving data items from the first clock domain, and an output port for transmitting data items to the second clock domain in a first-in first-out manner. The buffer has a first pointer for indication of a current first location of the buffer, and a second pointer for indication of a current second location of the buffer. The system further includes a read controller operable to define a read pattern for the buffer, to control output from the buffer in dependence upon such a read pattern, and to adjust such a read pattern in dependence upon a value of such a first pointer for the buffer.
