Abstract
Methods, systems, and apparatuses related to a communication switch are disclosed herein. In some embodiments, the communication switch may be configured to transmit TDM, ATM and/or packet data from an ingress service processor, through a plurality of switch elements, to an egress service processor. Other embodiments may be described and claimed.

-7. (canceled)
A method comprising:
- transmitting a bandwidth request element;
- receiving a grant corresponding to the bandwidth request element;
- generating a protocol data unit (PDU) including routing information, to facilitate routing of the PDU through a plurality of stages of a communication switch, and the PDU further including an indication of a first stage of the plurality of stages at which multicasting begins;
- and
- transmitting, based at least in part on said receiving of the grant, the PDU to the first stage.

A method comprising:
- generating a bandwidth request element including routing information, to facilitate routing of the bandwidth request element through a plurality of stages of a communication switch, and the bandwidth request element further including an indication of a first stage of the plurality of stages at which multicasting begins;
- and
- transmitting the bandwidth request element to the first stage.
A system comprising:
- a receive switch controller configured to generate a bandwidth request element including routing information, to facilitate routing of the bandwidth request element through a plurality of stages of a communication switch, and the bandwidth request element further including an indication of a first stage of the plurality of stages at which multicasting begins;
- and
- an interface coupled to the receive switch controller and configured to transmit the bandwidth request element to the first stage.
A system comprising:
- a receive switch controller to generate a protocol data unit (PDU) including routing information, to facilitate routing of the PDU through a plurality of stages of a communication switch, and the PDU further including an indication of a first stage of the plurality of stages at which multicasting begins;
- and
- an interface coupled to the receive switch controller and configured to transmit a bandwidth request element, to receive a grant corresponding to the bandwidth request element, and to transmit the PDU to the first stage based at least in part on said receiving of the grant.
A communications switch comprising:
- a first switch element including one or more ports;
- a second switch element including one or more ports;
- and
- a port processor including
- a first switch element interface coupled to a first port of the one or more ports of the first switch element;
- a second switch element interface coupled to a first port of the one or more ports of the second switch element;
- and
- a receive switch controller configured to automatically redirect traffic to either of said first or second switch element interfaces based at least in part on a switch congestion event.
5 more elements
A communications switch comprising:
- a switch element including a first port and a second port;
- and
- a port processor including
- a first switch element interface coupled to the first port;
- a second switch element interface coupled to the second port;
- and
- a receive switch controller configured to automatically redirect traffic to either of said first or second switch element interfaces based at least in part on a switch failure or congestion event.
4 more elements
A communications switch comprising:
- a first switch fabric including a plurality of first switch elements;
- a second switch fabric including a plurality of second switch elements;
- and
- a port processor including
- a first switch fabric interface coupled to one of the plurality of first switch elements,
- a second switch fabric interface coupled to one of the plurality of second switch elements, and
- a receive switch controller configured to automatically redirecting network traffic through either of said first switch fabric or said second switch fabric based at least in part on switch congestion.
4 more elements
A communications switch comprising:
- a plurality of switch elements;
- and
- a port processor configured to repeatedly transmit a request element through a first subset of the plurality of switch elements based at least in part on a first routing tag in the request element until a grant corresponding to the request is received or the request is transmitted through the first subset a predetermined number of times, and, in an event in which the request is transmitted through the first subset a predetermined number of times, to transmit the request element through a second subset of the plurality of switch elements based at least in part on a second routing tag in the request element.
