2 Backgrounds Illusion of one fits all IP network Variety of new services have added variety of new mechanisms complicated system management Closed access to infrastructure Expectation for Future Internet Clean slate architecture Variety in architecture t and birth-and-death d evolution Keep research(er) running; faster and faster Accelerate birth-and-death evolution with virtualization Page 2

3 Goal of our study Our goal is to develop technologies for infrastructure virtualization (and verify them on experimental NW) Openness to infrastructure Virtualization of infrastructure Modularity of infrastructure Programmability in infrastructure Substrate Site A Virtualisation of Resources ( Task 3.2) PWN PWN Urban Grid Access Network Sensor Net Suburban Hybrid Access Network PEC PEN PEN PEN GGW Internet Site B GGW PCN PCN Provisioning of Virtual Networks ( Task 3.3) GENI Backbone PCN Virtualised substrate Page 3 PWN USA: NSF GENI Project PWN: Programmable Wireless Node PEN: Programmable Edge Node PEC: Programmable Edge Cluster PCN: Programmable Core Node GGW: GENI Gateway Virtual Network Virtual Network Management of Virtual Networks ( Task 3.3) EU: FP7 4WARD Project

4 Basic approach Loosely coupled independent systems with embedded control-plane closed infrastructure Variety of data plane equipments and integrated control- plane open interfaces between them (control-plane := signaling plane or routing protocol plane, rather than management plane) Control system Service Control system Computer Control system IP network Control system Programmability at control plane (rather than data plane) Openness to infrastructure Integrated control plane Service Integrated control system Open interfaces Optical transport Mobile network Plain data-plane

5 Basic idea of OpenFlow (Network wide) separation of control and switching Variety of control software on controller Centralized programming Control software (routing, etc ) Hardware Control software (packet switching) (routing, etc ) OSPF/BGP Router / Switch Hardware (packet switching) Page 5 Control software (routing, etc ) Hardware (packet switching) Router / switch ルータ スイッチ NEC Confidential Controller Programmability for 制 御 ミドルウエア ミドルウエア (central) control Control (ルーティングなど) software (ルーティングなど) (routingf etc ) Virtualization of Network OS network control Open Interface Virtualization of switch instance Hardware プログラマブルノード ハードウエア ) (packet (フロー switching) 転 送 ) OpenFlow switch

6 Operation of OpenFlow switch Flow-based operation Proactive and reactive actions Flexible definition of Flow Variety of actions OpenFlow Switch specification OpenFlow Switch sw Secure Channel Deeply programmable (without modifying data-plane;, thus no performance cost) OpenFlow Controller Server hw Rule Action Statistics Rule Action Statistics Flow Table Add/delete flow entries Encapsulated packets Controller discovery Page 6

7 OpenFlow switch prototype development Works as OpenFlow switch : ) Switch virtualization (Virtual switch instance per VLAN) Multiple projects / complex network on a switch Legacy switch function for production traffic One virtual switch instance can be used as legacy switch Off cause, OpenFlow can emulate legacy functions...
