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.

8. 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. - View Dependent Claims (9, 10)

25. 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. - View Dependent Claims (26)

27. 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. - View Dependent Claims (28)

29. 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. - View Dependent Claims (30)
