4. Introduction
 Many network researchers have been working on
y g
developing new Internet architectures, services,
protocols and algorithms
 Any of such new ideas must be rigorously tested
and evaluated before being deployed in the actual
Internet
 Many kinds of network testbed have been
developed and some of them were widely used in
network research community
 However, most of these testbeds are built with the
,
legacy network technology and provide limited
networking experiment service for the researchers

5. Introduction
 SDN restructures network and exposes network APIs
p
so that any software can configure the network as
they want
 OpenFlow has been developing and is considered as
a promising candidate technology to realize SDN
 Th current testbed’s control software i tight
The b d’ l f is i h
coupling with their substrate resources
A an alternative, we use open and standard I S
As lt ti d t d d IaaS
cloud platform as the virtual infrastructure manager

20. Conclusion
 Propose a new Future Internet testbed architecture
p
based on the open Infrastructure-as-a-Service cloud
and Software Defined Network
 Design the experiment description framework, the
web-based access portal, the IaaS cloud and SDN
infrastructure, and the experiment resource
infrastructure
allocator.
 The initial implementation and test results show
that this new testbed architecture built on IaaS cloud
and SDN is feasible and flexible to provide new
services other than network experiment
