Patent ID: 7512134

Claim:
A method for transmitting a data packet received at a first routing entity in a switched network system having at least a Service Level to Virtual Lane (SL-to-VL) mapping table and comprising a plurality of input ports coupled to a plurality of output ports by multiple routing entities, the method comprising: a) assigning an output port to the data packet from a switch routing table associated with the switched network system; b) determining whether an output port is coupled to the first routing entity; c) assigning a local output port to the data packet from a local routing table associated with a first routing entity if the output port previously obtained is not coupled to the first routing entity; d) determining whether an input port is coupled to the first routing entity; e) associating a Virtual Lane (VL) to the data packet from the SL-to-VL mapping table if the input port is not coupled to the first routing entity; and f) placing the data packet in a VL queue buffer.
