3 Introduction of Okinawa Open Laboratory

4 Introduction of Okinawa Open Laboratory Research Institute Founded by NEC, NTT Communications and IIGA in May 2013 Based at Okinawa IT Shinryo Park (OISP), Okinawa, Japan Mission Research and development activities for practical application and dissemination of advanced Information Communications Technologies (ICT), especially next-generation ICT platform technologies, such as Software-Defined Networking (SDN) Cloud Computing using Open Source Software (OSS) Activities Verification of new technologies Development of use cases and reference models Education and training of engineers International conferences International exchanges, especially with Asian countries Information delivery on the above activities

5 Introduction of Okinawa Open Laboratory OOL connects OSS development communities and market via use cases and reference models to expand user base of next-generation ICT platform in cooperation with members and partners User Base Joint Activity with OOL <Members> Widely from - Industries - Academia From Worldwide - Japan - Asian Countries...

9 Introduction of my challenge

10 OpenDaylight can manage OpenFlow OF Switch OF Switch OF Switch OF Switch OF Switch

11 Motivation Manage mixed network technologies (OpenFlow, VPN, VLAN, etc)? OpenFlow Regacy

12 Motivation For example, how to manage environment mixed OF switch and L2 switch by OpenDaylight?? OF Switch OF Switch L2 Switch OF Switch OF Switch

13 First step: Topology Management Managing OpenFlow and Legacy L2 switches by OpenDaylight controller Manage OpenFlow topology Auto path recovery during link failure Auto configuration of a Legacy L2 switch

14 Projects using in our PoC Project VTN Manager SNMP4SDN SouthBound SNMP OpenFlow

15 Test #1 Testing topology management on mixing environment Result disable to get topology sending broadcast make it possible?

16 Test #2 Testing flows in OpenFlow switches when changing path between Host1 and Host2 Test situation port-map for VTN setting vlan in a L2 switch OF Switch 4 OF Switch1 L2 Switch OF Switch 3 Host 1 Host 2 OF Switch 2

17 Test #2 Testing flows in OpenFlow switches when changing path between Host1 and Host2 Test situation invoke link failure on the L2 switch Result changing flow correctly OF Switch 4 OF Switch1 L2 Switch OF Switch 3 Host 1 Host 2 OF Switch 2

18 To make first step realized detecting events (link failure etc) from a L2 switch switching a path automation (for HA) getting OpenFlow topology in mixing environment

19 Introduce Orchestrator

20 What is Orchestrator? Managing the topology of mixed network Monitoring the status of each network Configuring logical network between each network

21 Why Orchestrator? Give an interoperability in OpenDaylight - Example: managing overlay and underlay network Pursue easy usability for users - Example: easy to manage L2 and OpenFlow Switches Enable integrate OpenDaylight projects - Example: integrate VTN and SNMP4SDN

22 Use case (HA) Orchestrator DB 2. Notification for failure by SNMP trap 3. update link status search another path on L2 topology If found another path, changing to the 4. Change vlanid path (change VLAN) vlan10 1. Link failure vlan10 OF Switch OF Switch L2 Switch vlan10 OF Switch OF Switch

23 Future Plans make ODL controller HA develop Orchestrator more test other cases for mixing environment (Load balancer,vpn, etc) network automation Integrate OpenStack Neutron

24 Summary There are the difficulty for ODL to manage mixed environment the orchestrator provides ODL with the function. join OOL!!
