Software-defined networking tunneling extensions

摘要

An aspect includes receiving, at a software-defined networking (SDN) controller, a request from a requestor to identify a flow of a data packet in a computer network. The data packet includes a data packet header. It is determined, based on the data packet header, that the data packet includes one of a peripheral component internet express (PCIe) data packet and a multi-root input/output (MR-IOV) data packet. It is also determined that the flow of the data packet requires a virtual tunnel between a source network device and a destination network device. The creation of the virtual tunnel is initiated and the requestor is instructed to send the packet from the source network device to the destination network device via the virtual tunnel. The requestor is also instructed to use the virtual tunnel for sending subsequent packets having the same flow and received prior to the virtual tunnel being shut down.

1. A computer-implemented method for software-defined networking (SDN) in a computer network, the method comprising:
receiving, at a SDN controller in the computer network, a request from a requestor to identify a flow of a data packet from a source network device to a destination network device in the computer network, the data packet including a data packet header; determining, by the SDN controller, based on the data packet header, that the data packet includes one of a peripheral component internet express (PCIe) data packet and a multi-root input/output (MR-IOV) data packet, and that the flow of the data packet requires a virtual tunnel between the source network device and the destination network device; initiating, by the SDN controller, creation of the virtual tunnel in the computer network; instructing, by the SDN controller, the requestor to send the packet from the source network device to the destination network device via the virtual tunnel; and instructing the requestor to use the virtual tunnel for sending subsequent packets having the same flow and received prior to the virtual tunnel being shut down.
