Framework for Traffic Engineering in Software Defined Networking

摘要

System and method embodiments are provided for traffic engineering (TE) in software defined networking (SDN). The embodiments enable a complete end-to-end TE solution between a user equipment (UE) and a source/destination across a radio access network (RAN). In an embodiment, a method in a network component for TE in a SDN includes receiving TE information from a first core network component in a core network, a RAN component, wherein the RAN is communicably coupled to the core network, wherein the TE information includes a TE objective; and determining a TE decision between at least one UE and a second core network component in the core network according to the TE information and the TE objective, wherein the TE decision comprises information for at least one end-to-end path solution between the at least one UE and the second core network wherein the path traverses the core network and the RAN.

1. A method for traffic engineering (TE) in a software defined network (SDN), the method comprising:
receiving, by a TE component, a first TE information from a core network component in a core network; receiving, by the TE component, a second TE information from a radio access network (RAN) component in a RAN; and transmitting, by the TE component, a TE decision to at least one node in the SDN, wherein the TE decision is determined according to the first TE information and the second TE information, and the TE decision comprises at least one end-to-end path solutions based on a flow-path format or flow-link format.
