Virtualization has become a key component of network testbeds. However, transmitting data or commands to the test nodes is still either a complicated task or makes use of the nodes' network interfaces, which may interfere with the experiment itself. This paper creates a model for the typical lifecycle of experiment nodes, and proposes a mechanism for networkless node control for virtual nodes in such a typical experiment lifecycle which has been implemented in an existing testbed environment.
The Internet is a successful network that connects people all over the world. However, it has some fundamental architectural problems which require application developers and service providers to spend a tremendous effort in combating these. Examples for these efforts are content delivery networks or mobile TCP. Thus, it can be said that the Internet is currently not fulfilling the requirements on the global network anymore. The Internet of the future, or its replacement, must solve these problems.There are multiple clean-slate approaches for information-centric networking. However, they are inherently incompatible to the Internet or applications building on it.This work presents a novel resource transport protocol that is optimized for detection by software-defined networks and may be re-routed to in-network processors. Furthermore, it is shown how this protocol can be used to support concepts of ICN even in today’s Internet. Moreover, the resource format that is used in this work is independent from the underlying network, resulting in possible reuse in other networks as well. Applications and protocols building on this resource format can thus easily be re-used in clean-slate networks like NDN.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
