دانلود Graph Abstraction Based Virtual Network Management Framework For SDN

Abstract

Currently,   Software   Defined   Networking   (SDN) paradigm  has  attracted  a  significant  interest  from  industry  and academia  as  a  future  network  architecture.  The  programmable control plane enables flexible and rapid modifications of network behavior.  With  OpenFlow,  one  of  the  promising  SDN  protocols, we can provide several advantages to develop advanced network virtualization  technologies.  In  this  paper,  we  propose  a  graph abstraction  based  virtual  network  management  framework  that covers  from  tenant  requirement  specification  to  virtual  network embedding  on  physical  resources.  The  fundamental  idea  is  to automatically  create  and  manage  virtual  networks  on  the  top of  SDN  technologies  from  high  level  tenant  requirements.  We expect that the proposed framework can overcome the limitation of overlay based network virtualization technologies, and leverage the deployment of SDN technologies.
