to pay attention to standards’ issues. CASTLE offers an API in MATLAB and C++. For Windows, Linux and OSX.
CASTLE also allows the management through web interface, inspired in OpenStack. The external access is
achieved by means of life-limited license granted by CTTC. With this access, the researcher can use the Test
Bed remotely by the web interface and/or the use of an API, which interfaces between the researcher’s local
machine and remote CASTLE Test Bed. The communication between the researcher and the CTTC is ciphered
using a 128-bit AES standard.

IoTWORLD Testbed
IoTWORLD (http://iotworld.cttc.es/) is an End-to-End testbed for the Internet of Things. The main focus is on
Wireless Communications systems and data analytics. The testbed has been deployed in two different
neighbor buildings: in a laboratory, in an isolated room, and in a real office environment. IoTWORLD is a
unique testbed for the Internet of Things. It features: Heterogeneity of wireless technologies, scalable design,
integration with 5G technologies and end-user involvement. Different sensors and actuators are connected
to a set of gateways, either with a direct connection or via multiple hops. These gateways are then connected
to the Internet, providing the capability to retrieve and store data in the cloud, among other functionalities,
such as data fusion, compression and analytics. An innovative software middleware has been developed for
these gateways. This software makes the integration of new wireless technologies very simple, thus
overcoming the heterogeneity barrier. The data gathered by the sensors is stored in the cloud. From there,
it is possible to have access to them from a web interface or from a smartphone application. Actuators
connected to the IoTWORLD testbed can also have access to these data. IoTWORLD permits to obtain
valuable information from the data measurements by means of data analytics on the edge. For this purpose,
software defined networking is a key enabler to realize a flexible communication between the different
computing entities.

6.3.3 Testbed prototyping for network softwarization by NICT

RISE: A multi-tenancy SDN testbed, where multiple SDN-controlled user networks (i.e., tenants)
simultaneously work on a SDN-controlled physical network consisting of OpenFlow switches and physical
computation servers [Ref.6.3.3-1]. The RISE orchestrator makes a slice consisting of a number of virtual
machines and flow spaces of OpenFlow switches and assigns it for each user request. Each user network is
then empowered to control the OpenFlow switches and use VMs that are distributedly deployed in JGN-X, a
nation-wide R&D network testbed in Japan. VMs can be used such as hosts, network function elements, SDN
controllers in the network. Multiple tenants use the RISE simultaneously.

JOSE: An infrastructure as a service specialized for IoT services [Ref.6.3.3-2]. It is intended for multiple large-
scale field trials using functional elements such as sensor networks, storage resources, computation
resources and networks that connect the functional elements. 20,000 VMs and 1 PByte of storage are
provided. The JOSE manager can setup a 200-VM class field trial environment by approximately 13 minutes
including VM start-up time, storage setup, VM set up, and user setup.

HIMALIS TB: An ID-based communication testbed on JGN-X. HIMALIS [Ref.6.3.3-3] supports mobility and
heterogeneous communication and is compliant with Recs. ITU-T Y.3032 and Y. 3034. The capability of
HIMALIS gateways are installed in several routers of JGN-X as distributed mobility anchor (MA) points that
avoid single point of failures like a case of Proxy Mobile IP. MAs may be intended to be installed close to
BBUs. A registry system and number of mobile hosts (user equipment in other words) are installed in VMs in
JGN-X.
