Abstract:
1. A method of sequentially processing a frame in a data center, the method comprising: receiving at an ingress port of a switch device a frame originating from an initiating system and requiring sequential processing by a first computing system and a second computing system of the data center; identifying by the switch device, in response to information carried in the frame, a first of a plurality of egress ports of the switch device and exclusively passing the frame to the first of the plurality of egress ports; exclusively forwarding the frame, by the switch device, from the first egress port to the first computing system: receiving the frame at the switch device in return from the first computing system after the first computing system completes processing the frame; identifying, by the switch device, in response to information carried in the frame received in return from the first computing system, a second egress port of the plurality of egress ports of the switch device and exclusively passing the frame to the second egress port; and exclusively forwarding the frame, by the switch device, to the second computer system from the second egress port for processing by the second computing system before the frame is returned through the switch device to the initiating system.
