The second housing includes a second interface card of the switch fabric and a third interface card of the switch fabric. The second interface card of the switch fabric is operatively and physically coupled to the third interface card of the switch fabric via a midplane. The second interface card defines a plane that is nonparallel to the a plane defined by the third interface card and a plane defined by the midplane. The plane defined by the third interface card is nonparallel to the plane defined by the second interface card and the plane defined by the midplane. The cable is configured to operatively couple the first interface card to the second interface card.

摘要： In one embodiment, an apparatus includes a switch core that has a multi-stage switch fabric physically distributed among a set of chassis. The multi-stage switch fabric has a set of input buffers and a set of output ports. The switch core can be configured to be coupled to a set of edge devices. The apparatus can also include a controller implemented in hardware without software during operation and with software during configuration and monitoring. The controller can be coupled to the set of input buffers and the set of output ports. The controller can be configured to send a flow control signal to an input buffer from the set of input buffers when congestion at an output port from the set of output ports is predicted and before congestion in the switch core occurs.

摘要： In one embodiment, an apparatus includes a switch core that defines a single logical entity and has a multi-stage switch fabric that has a set of stages physically distributed across a set of chassis. The set of stages collectively has a set of ingress ports and a set of egress ports. The switch core can be configured to be coupled to a set of peripheral processing devices via the set of ingress ports and the set of egress ports. The switch core can be configured to admit a set of cells associated with a packet into an ingress port from the set of ingress ports when delivery of the set of cells can be substantially guaranteed without loss through the multi-stage switch fabric.

摘要： In one embodiment, a method includes sending a configuration signal to a virtual network switch module within a control plane of a communications network. The configuration signal is configured to define a first network rule at the virtual network switch module. The method also includes configuring a packet forwarding module such that the packet forwarding module implements a second network rule, and receiving status information from the virtual network switch module and status information from the packet forwarding module. The status information is received via the control plane.
