摘要： A distributed switching fabric system includes multiple network switches coupled to a cell-based switching fabric by cell-fabric ports. A virtual machine runs on a server connected to a network port of one or more of the network switches that are members of a given switching domain. The virtual machine manages a control plane for the given switching domain. The server receives a protocol control packet from one of the network switches and forwards the received protocol control packet to the virtual machine for processing.

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.

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.
