SDN METHOD AND FRAMEWORK FOR TRAFFIC ENGINEERING IN NETWORK HYPERVISOR OF SDN-BASED NETWORK VIRTUALIZATION PLATFORM

摘要

A network hypervisor for implementing software defined network (SDN) based network virtualization is disclosed. The network hypervisor receives a first routing message from a policy manager module that receives a Quality of Service (QoS) parameter and a controller of each of a plurality of generated virtual networks, and virtual path information corresponding to the first routing message. A virtual path generator module for generating a physical path corresponding to the virtual path information received from the virtual path generator module and satisfying a QoS parameter received from the policy manager module, wherein the physical path is information on the physical path A load balancing module for generating information, and a physical message generator module for generating a physical message based on the physical path information received from the load balancing module, and transmitting the physical message to at least one switch included in the physical path. It includes.
