Abstract:
The non-limiting embodiments of the present technology relate to the data transmission technology in packet-switched Software Defined Networks (SDN), comprising switches with Ethernet ports and controlled by software controllers. The aim of this technical solution is to increase network switches' resource efficiency by establishing frame transport path in the network with MPLS transport tags set by the network controller as well as to reduce software functional requirements for OpenFlow switches and controllers by supporting standard frame fields processing. Method for forming an Ethernet frame and methods for transferring the Ethernet frame are disclosed.

Claim (Index 2):
A method of transferring an Ethernet frame, the Ethernet frame having been formed by the method of  claim 1 , the method executable by the supervisory computing apparatus, the method comprising:\n receiving, at an input port of the at least one intermediate software-defined switch, the modified frame; identifying a value of the EPI of the modified frame; responsive to a field value of the EPI satisfying a pre-determined condition:\n reading a first MPLS header; \n responsive to an MPLS label from the first MPLS header being within an output port range:\n deleting the first MPLS header tag and reading a second MPLS header tag describing the saved EPI, \n converting the modified frame into an original format of the frame prior to executing the method of  claim 1  by deleting the second MPLS header and restoring the Ethertype field in the frame to the saved EPI, and \n sending the frame to an output port specified in the first MPLS label; and \n \n responsive to an MPLS label from the first MPLS header being outside an output port range:\n swapping or removing the MPLS label in the first MPLS header from the frame, and \n sending the modified frame to a next switch according to the most preferable path.
