Overview

 OpenFlow Testbed in TWAREN  HPDMnet Multicast Streaming with OpenFlow  Future Work

2

Future Internet

 There are many serious limitations in current Internet.

 Scalability  Security  QoS  Virtualization

 Future Internet is a summarizing term for worldwide

research activities dedicated to the further development of the original Internet. (From Wiki)

3

Future Internet Testbed

 For innovations and researches in Future Internet,

the testbed requires some advanced concepts:

 Programmability  Virtualization  End-to-end slice

4

OpenFlow

 Make deployed networks programmable  Makes innovation easier  No more special purpose test-beds  Validate your experiments on production network at full line

speed

HPDMnet Overview

 An International Consortium of Research Centers Has Formed a

Cooperative Partnership



To Address Key Challenges and Opportunities Related to Using Dynamically Provisioned Lightpaths for High Performance Digital Media (HPDM)

 Multiple Sites Require High Performance/High Volume/High Definition

Digital Media Streaming Simultaneously Among All Locations (Point-To- Multipoint, Multipoint-To-Point, Multi-Point to Multi-Point)

 This Consortium Is Designing and Developing New L1/L2 Capabilities

That Can Provide Large Scale HPDM Services, Which Can be Used for Any Data Intensive Application, Not Just Digital Media

Lessons Learned

 Video transferred over FI testbed is not as smooth

as over legacy Internet.

 There are mosaics appearing every second.

 Because IGMP is not supported in OpenFlow, we

have to manually insert multicast streaming flows into the flow table.

Future Work

 Extend FI Testbed  Inter-OFCloud Control and Monitoring Development

with Domestic Universities

Manage Plane Data Plane

Inter-Cloud Control and Monitoring

 Each Cloud has its own OF Controller

 Each Controller manages topology and flow

provisioning inside the cloud

 Inter-Cloud flow could be made by connecting

partial flows provisioned by controllers of each cloud

 Lack of global view for inter-cloud flows  No loops allowed for inter-cloud topology  Difficult to support QoS or SLA functions across clouds
