Abstract
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).
