In realizing futuristic services with agility, testbed environments that provide converged computing/networking resources based on SDN (Software-Defined Networking) and CC (Cloud Computing) are becoming important. Following this trend, OF@TEIN OpenFlow-enabled SDN testbed environment is built with internationally-distributed unique SmartX Racks. In this paper, to automate the multi-point L2 inter-connections of OpenFlow islands, we design and implement a configuration tool for NVGRE (Network Virtualization using Generic Routing Encapsulation) tunneling. The proposed tool manages the desired topology by leveraging the OVSDB (Open vSwitch Database) configuration interface for OpenFlow switches. With the implemented tool and appropriate admin/user privilege management, we can quickly inter-connect the multi-point international OpenFlow islands while letting users to freely control (i.e., tag/steer/map) their own flows for experimentation.

The requirement of auto provisioning, administration, management and governing of networking resources in distributed environment, which spreads over multiple administrative domains (i.e., multi-domain) is a challenging task. This paper demonstrates an effort to inter-connect distributed SDN-Cloud resources which spread over three administrative domains in three different countries on OF@TEIN Playground. The proposed SD-Routing-Exchange utilizes BGP routing protocol as control-plane for federated multi-domain SDN-Cloud data-plane. This method has improved the flexibility of networking control, and provides reasonable interconnections redundancy and performance enhancement.

“…Infrastructure for research and development of distributed systems have been established over the years [13,33,2], including platforms for SDN solutions [12] and SDN testbeds [27,29,37,32]. Our approach and previously described platforms have many similarities, but we focus on providing an infrastructure that may be used for both evaluating SDNbased solutions and assessing their energy efficiency.…”

Designing and building SDN testbeds for energy-aware traffic engineering services

As experimenting with energy-aware techniques on large-scale production infrastructure is prohibitive, a large number of proposed traffic-engineering strategies have been evaluated only using discrete-event simulations. The present work discusses (i) challenges towards building testbeds that allow researchers and practitioners to validate and evaluate the performance and quality of energy-aware traffic-engineering strategies, (ii) requirements to fulfill when porting simulations to testbeds, and (iii) two proof-of-concept testbeds. One testbed uses and provides Software-Defined Network (SDN) services created on the Open Network Operating System (ONOS) while the other is a composition of virtual Open vSwitches (OVS) controlled by the Ryu SDN framework. The aim of the testbeds is to validate previously proposed energy-aware traffic engineering strategies in different environments. We detail the platforms and illustrate how they have been used for performance evaluation. Additionally, the paper compares results obtained in the testbeds with evaluations performed using discrete-event simulations and presents challenges faced while implementing energyaware traffic engineering mechanisms as SDN services in testbed environments.
