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 1):
A method of forming an Ethernet frame, the method executable in a software-define network (SDN), the SDN including (i) a first software-defined switch, (ii) a second software-defined switch, and (iii) at least one intermediate software-defined switch interconnected by respective links, all forming a connected switch graph, the SDN further including a supervisory computing apparatus communicatively coupled to the all software-defined switches, the method executable by the supervisory computing apparatus, the method comprising:\n receiving, at an input port of the first software-defined switch, a frame; determining, based on the frame being destined to the second software-defined switch, an output port of the second software-defined switch; generating, by the supervisory computing apparatus, a most preferable path to the output port; encoding, by the supervisory computing apparatus, the most preferable path using with at least one multiprotocol label switching (MPLS) transport tag; modifying, by the supervisory computing apparatus, the frame by executing:\n retrieving an embedded protocol identifier (EPI) from one of an Ethertype or a VLAN TPID field of the frame; \n replacing the EPI in the frame with a predefined constant; \n adding an MPLS header to the frame with the MPLS label containing the retrieved EPI; \n adding at least one MPLS header to the frame with the MPLS label encoding the most preferable path; and \n sending the modified frame to a next switch according to the most preferable path.
