VIRO-GENI: SDN-Based Approach for a Non-IP Protocol in GENI

Abstract

Non-IP protocols always presents a challenge for network researchers to deploy and test using the existing IP based network infrastructure. By leveraging a variety of novel networking techniques and platforms such as network virtualization, OpenFlow and SDN, GENI has been developed by the research community as a viable wide-area testbed to enable at-scale network experimentations. However, as the current Openflow standard is closely tied to the Ethernet/IP/TCP protocol stack, implementing-and experimenting with-non-IP protocols in GENI still faces many challenges. In this paper, we present a SDN-based framework to design, implement and deploy a non-IP protocol, Virtual Id Routing (VIRO), in GENI using an extended Open vSwitch platform.

In-Network Dynamic Pathlet Switching with VIRO for SDN Networks

“…We are now in a position to discuss our experiments. Experiment Setup: we carry out experiments to investigate the potential benefits of in-network pathlet switching and we 5 i.e., by manually inserting OpenFlow rules to switch paths based on VIRO routing protocol 6 a level-3 GW in the list of GWs received from the rdv point compare it with mpTCP. To achieve this, we use the network topology illustrated in Figure 4.…”

“…By decoupling addressing from routing, it also enables access control as packets enter a network, and allows other security features to be incorporated into the network control and management more seamlessly. We have implemented and deployed VIRO in GENI (the Global Environment for Network Innovations [2]) using the SDN/OVS software platform [5], [1].…”
