    摘要: A system and method are provided for tolerating data line faults in a packet communications network. The method comprises: serially transmitting information packets from at least one traffic manager (TM); at a switch fabric, accepting information packets at a plurality of ingress ports, the information packets addressing destination port card egress ports; selectively connecting port card ingress ports to port card egress ports; serially supplying information packets from a plurality of port card egress ports; sensing a connection fault between the switch fabric and the TM; and, in response to sensing the fault, reselecting connections between the switch fabric port card ports and the TM. Some aspects comprise: an ingress memory subsystem (iMS) receiving cells on an ingress port exceeding an error threshold. Then, reselecting connections between the port card ports and the TM includes the iMS sending a message to the iTM identifying the faulty ingress connection.

    摘要: A system and method are provided for configuring interface bandwidths in a packet communications switch fabric. The method comprises: interfacing data links with a first plurality of traffic managers (TMs); differentiating port card interface ports into a first plurality of subchannels associated with the first plurality of TMs; and, communicating packets information with the TMs at a first plurality of data rates corresponding to the first plurality of subchannels. More specifically, differentiating port card interface ports into a first plurality of subchannels associated with the first plurality of TMs includes: differentiating a second plurality of ingress data links into a third plurality of ingress subchannels associated with a third plurality of ingress traffic managers (iTMs); and, differentiating a fourth plurality of egress data links into a fifth plurality of egress subchannels associated with a fifth plurality of egress TMs (eTMs).

    摘要: A system and method are provided for controlling packet header information in a packet communications switch fabric. The method comprises: programming the cell header overhead (OH) field definitions; accepting a packet including a plurality of cells and corresponding cell headers, each cell header including a plurality of overhead fields; defining the cell header OH fields; and, transmitting the packet. Defining the cell header OH fields includes defining cell header OH field location, position, meaning, structure, and length. In other aspects, the method comprises redefining the cell header overhead fields, once they are accepted. For example, the OH field information can be modified, relocated, or an OH field can be added to the cell header. In yet other aspects, the OH field information can be extracted and/or reformatted.
