Abstract:
1. A method for forwarding received data for a logical link, the method implemented in a switch device in a multistage switch, the multistage switch comprising a matrix of switch devices connected to each other through internal output ports, the logical link comprising a plurality of physical links and coupling the multistage switch to a destination through a plurality of output ports connected to the multistage switch, the method comprising: upon determining at a switch device of the matrix of switch devices to forward the received data to one of the physical links of the logical link, selecting a trunk table associated with the logical link from a plurality of trunk tables, each trunk table including trunk table entries; and computing a forward vector for the received data dependent on a selected trunk table entry for the received data, the forward vector indicating where the received data is to be forwarded forwarding the received data to the internal output port indicated by the forward vector, and the forward vector indicating the internal output port through which to forward the received data.
