摘要： An Ethernet switch for preventing head of line blocking by passing an Ethernet packet carrying congestion status information among Ethernet switches over the Ethernet. When a port of an Ethernet switch is congested, the switch informs other Ethernet switches by broadcasting to other switches over the Ethernet an Ethernet packet indicating that the port is congested. If another Ethernet switch finds that one of its traffic classes is destined to the congested port, this switch drops packets of that traffic flow until receiving an Ethernet packet indicating that the congestion is alleviated.

摘要： A method for transferring data includes connecting N ports of a crossbar to N devices, respectively, where N is an integer greater than one. Inbound data is received at one of the N ports from a respective one of the N devices. Dedicated connections are provided between an input buffer of one of the N ports and N−1 output buffers associated with others of the N ports, respectively. At least one of the N−1 output buffers of the others of the N ports is selected to output outbound data corresponding to the inbound data. The inbound data from the input buffer of one of the N ports is selectively transferred to at least one of the N−1 output buffers of the others of the N ports.

摘要： A network switch which includes a plurality of output ports, at least one input port and a queuing manager. Each output port has a control unit associated therewith. The input port receives incoming data destined for various ones of the output ports. The queuing manager directs the incoming data to their destination output ports. Each control unit includes an output queue, a fullness/emptiness sensor and a head of line (HOL) mask. The output queue stores the incoming data destined for its associated output port. The sensor senses when the output queue reaches a fullness or an emptiness state. The HOL mask is connected to the output of the sensor and blocks inflow of the incoming data to the output queue when the sensor senses the fullness state and for enabling inflow when the sensor senses the emptiness state.

摘要： A method for preventing head of line blocking in an Ethernet system. In one embodiment, a network interface detects whether there is traffic flow congestion between the network interface and a data processing unit such as a CPU or other peripheral. If yes, the network interface communicates the congestion status to its attached Ethernet switch. In another aspect of the invention, the Ethernet switch then stops serving the congested port or queue, and informs a switch from which the traffic flow causing the congestion originates. In a further aspect, the originating switch then reduces bandwidth for the traffic flow causing the congestion. In a still further aspect, the originating switch can take the bandwidth that it acquired because of reducing the congesting traffic flow, and use it to increase bandwidth for other traffic flow.

摘要： A method and apparatus for managing packet memory is provided. The apparatus includes an empty list, a storage buffer and apparatus for updating the storage buffer and empty list. The empty list includes a multiplicity of single bit buffers. The storage buffer includes a multiplicity of contiguous buffers, wherein each single bit buffer is associated with one of the contiguous buffers. The state of the bit of a single bit buffer indicates the empty or full state of the associated contiguous buffer and the address of a contiguous buffer is a simple function of the address or number of its associated single bit buffer. The updating apparatus stores data in and removes data from the contiguous buffers and correspondingly updates the states of the associated single bits buffers.
