A data center includes a switch device, an initiating system, and first and second computing systems. A frame is received at an ingress port of the switch device from the initiating system. The frame requires processing sequentially by the first and second computing systems. Identified, in response to information carried in the frame, is a first egress port through which to forward the frame to the first computer system. The frame is received in return from the first computing system after the first computing system completes processing the frame. In response to information carried in the frame received from the first computing system, a second egress port is identified through which to forward the frame to the second computer system. The frame is forwarded to the second computer system through the second egress port for processing by the second computing system before the frame is returned to the initiating system.
