Claim Text:
1. A method of data switching, comprising: receiving a packet from a source port into a top of rack (TOR) switch, the source port being one of a plurality of ports on the top of rack switch, the plurality of ports capable of being coupled to a plurality of servers on one or more racks; processing a packet header of the packet to determine a destination port; determining whether the destination port is on the TOR switch; segmenting the packet to provide segmented packets to a logical switching fabric that includes a local switch fabric on the top of rack switch and a Core switching fabric on a Core switch; when the destination port is on the TOR switch, providing the segmented packets without a TOR header to the local switch fabric; when the destination port is on a different TOR switch, providing the segmented packets with the TOR header to the Core switch fabric, wherein the TOR header eliminates a need to processes the packet header to determine the destination port at the Core switch; and switching the segmented packets through the logical switching fabric.
