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 method of broadcasting a packet to the ports belonging to one VLAN of a network, whereas the network has multiple network switches. Each network switch has its own local ports and a local VLAN table. Each local VLAN table stores local port membership of its network switch, and switch membership per VLAN identifier. The local VLAN table is accessed by a VLAN identifier which is stored in the packet, and retrieves the local port membership and switch membership associated with the VLAN identifier. A copy of the packet is provided to each local port and to each switch retrieved from said local VLAN table.

摘要： An Ethernet controller, for use within an Ethernet network of other Ethernet controller connected together by a bus, is provided. The Ethernet controller includes a plurality of ports including at least one bus port associated with ports connected to other switching Ethernet controllers, a hash table for storing addresses of ports within the Ethernet network, a hash table address control, a storage buffer including a multiplicity of contiguous buffers in which to temporarily store said packet, an empty list including a multiplicity of single bit buffers, a packet storage manager, a packet transfer manager and a write-only bus communication unit. The hash table address control hashes the address of a packet to initial hash table location values, changes the hash table location values by a fixed jump amount if the address values stored in the initial hash table location do not match the received address, and provides at least an output port number of the port associated with the received address. The packet storage manager associates the state of the bit of a single bit buffer with the empty or full state of an associated contiguous buffer and generates the address of a contiguous buffer. The packet transfer manager directs the temporarily stored packet to the port determined by said hash table control unit. The write-only bus communication unit is activated by the packet transfer manager, for transferring the packet out of the bus port by utilizing the bus for write only operations.
