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： Featured are a system and method for providing a distributed switch system (DSS) in a TRILL-compliant network. An ingress network device in the TRILL-compliant network provides data to a received packet. The data includes instructions related to a feature of the DSS. The instructions are inserted into a TRILL header generated at the ingress network device. The TRILL header is output to an egress network device in the TRILL-compliant network. A determination is made whether the ingress network device and the egress network device are members of the DSS. The instructions are processed by the egress network device in response to determining that ingress and egress devices are members of the DSS.

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.

摘要： A distributed system includes first-tier entities, and a master entity in communication with each first-tier entity. The master entity provides a single access point through which an administrator can submit commands to manage all entities. The master entity maintains a table of virtual slots. Each virtual slot points to one of the first-tier entities, and each first-tier entity is pointed to by at least one virtual slot. The processor runs an RPC (remote procedure call) client to submit RPC requests to the first-tier entities, and determines a destination first-tier entity for a given RPC request in response to which virtual slot the administrator submits a command. The distributed system can include second-tier entities, each indirectly communicating with the master entity through a first-tier entity. The table has a virtual slot for each second-tier entity, which points to the first-tier entity acting as proxy for the second-tier entity.
