A FUTURE INTERNET TESTBED BASED ON IAAS CLOUD AND SOFTWARE DEFINED NETWORK

摘要

During last years,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,while the testbed control software is tight coupling with their substrate resources,which make it difficult to be used by other services.In this paper,we propose a new Future Internet testbed architecture based on the open Infrastructure-as-a-Service cloud and Software Defined Network paradigm,including the experiment description framework,the web-based access portal,the IaaS cloud and SDN infrastructure,and the experiment resource allocator.Our 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.
