摘要： A generally full-wire throughput, switching Ethernet controller used within an Ethernet network of other switching Ethernet controllers connected together by a bus. The controller comprises a plurality of ports including at least one bus port associated with ports connected to other switching Ethernet controllers. A hash table stores MAC addresses and VLAN ids of ports within said Ethernet network. A hash table address control hashes the MAC address and VLAN id of a packet to initial hash table location values, changes the hash table location values by a fixed jump amount if the address and VLAN id values stored in said initial hash table location do not match the received address and VLAN id, and provides at least an output port number of the port associated with the received address and VLAN id. A storage buffer includes a multiplicity of contiguous buffers in which to temporarily store said packet.

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 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.

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 switch controller includes a plurality of ports, a hash table, and a hash table control unit. The plurality of ports includes at least one bus port associated with ports connected to other switch controllers in a network. The hash table stores MAC addresses and VLAN ids of ports within the network. The hash table control unit hashes a MAC address and a VLAN id of a packet to identify a first location in the hash table. For each one of the VLAN ids stored in the hash table, one of the MAC addresses identifies one of the other switch controllers having ports belonging to the one of the VLAN ids without identifying each one of the ports of the one of the other switch controllers that belongs to the one of the VLAN ids.
