摘要： A distributed fabric system has distributed line card (DLC) chassis and scaled-out fabric coupler (SFC) chassis. Each DLC includes a network processor and fabric ports. Each network processor of each DLC includes a fabric interface in communication with the fabric ports of that DLC. Each SFC includes at least one fabric element and SFC fabric ports. A fabric communication link connects each SFC fabric port to one DLC fabric port. Each fabric communication link includes cell-carrying lanes. Each fabric element of each SFC detects connectivity between each SFC fabric port of that SFC and one DLC fabric port over a fabric communication link. Each SFC includes program code that reads connectivity matrix from fabric element chips and sends connection information corresponding to the detected connectivity from that SFC to a central agent. A network element includes the central agent, which, when executed, constructs a topology of the distributed fabric system from the connection information sent from each SFC.

摘要： A system includes scaled-out fabric coupler (SFC) boxes and distributed line card (DLC) boxes. Each SFC box has fabric ports and a cell-based switch fabric for switching cells. Each DLC box is in communication with every SFC box. Each DLC box has network ports receiving packets and network processors. Each processor has a fabric interface that provides SerDes channels. The processors divide each packet received over the network ports into cells and distribute the cells of each packet across the SerDes channels. Each DLC box further comprises DLC fabric ports through which the DLC is in communication with the SFCs. Each DLC fabric port includes a pluggable interface with a given number of lanes over which to transmit and receive cells. Each lane is mapped to one of the SerDes channels such that an equal number of SerDes channels of each fabric interface is mapped to each DLC fabric port.

摘要： A network fabric includes interconnected network nodes, each having access to a database containing predetermined paths from each network node to each other network node in the network fabric. Each network node determines, in response to an incoming frame, whether the frame is a fabric protocol data unit (PDU) having a header containing path attributes including a destination node address. If the frame is a fabric PDU, the node selects a first path to the destination node from the database, and forwards the fabric PDU to a next hop in accordance with the selected path. If the frame is not a fabric PDU, the node selects a second path through the network fabric to the destination node from the database, adds the header with the path attributes to the frame to produce the fabric PDU, and forwards the fabric PDU to the next hop in accordance with the second path.

摘要： A distributed fabric system comprises a plurality of independent network elements interconnected by inter-switch links and assigned to a same group. Each network element includes a switching chip, a processor, and memory storing program code that is executed by the processor. The program code of each network element includes a device configuration (DC) stacking module and a switch discovery protocol (SDP) module. The SDP module of each network element, when executed, discovers each other network element in the group and elects one of the network elements as a master network element. The SDP module of the master network element, when executed, sends messages to the DC-stacking module of the master network element. Each sent message identifies one of the network elements in the group. The DC stacking module of the master network element, when executed, maintains a record of all network elements that are currently members in the group.

摘要： Method and apparatus for managing traffic of a switch include logically partitioning a physical port of the switch into a plurality of virtual ports. One or more virtual output queues are uniquely associated with each virtual port. Switching resources of the switch are assigned to each of the virtual ports. A source virtual port is derived from a frame arriving at the physical port. The frame is placed in a given one of the one or more virtual output queues uniquely associated with the source virtual port derived from the frame. A destination virtual port for the frame is determined. The frame is transferred from the virtual output queue in which the frame is placed to an egress queue associated with the destination virtual port and forwarded from the egress queue to a destination physical port of the switch.
