iPOP2018 Showcase: Software-Defined Networking and Network
Virtualization Technologies for Various Applications
Introduction

Software-defined networking (SDN) and network virtualization technologies have attracted considerable
attention from both academia and industry. Significant efforts have been focused on the efficient use ofavailable network resources that can be achieved via more automation (e.g. SDN) and increased flexibilityof the networks (e.g. virtualization) in order to mitigate CAPEX and OPEX in the communication networks.
The iPOP2018 showcase presents a number of demonstrations that are based on SDN and network
virtualization technologies in support of various applications. Briefly described below there are six
network configuration use cases, which include (1) data-analytics-based optical performance monitoring
assisted by container technique, (2) dynamic construction and control of virtual network platform utilizing
OpenStack, (3) inter-carrier connection technology for critical traffic in the event of a disaster, (4) openand disaggregated transport network, (5) dynamic virtual machine (VM) migration with dynamic multilayer configuration in support of autonomous driving vehicles (ADVs), and (6) optical slot switching (OSS)
technology for future SDN controlled optical data-center networks.
Showcase network configuration
Figure 1 shows the showcase testbed configuration. The data plane of the testbed is implemented at theNational Institute of Information and Communications Technology (NICT) premises in Tokyo, Japan. The
testbed consists of a beyond 100-Gb/s-based transport network (Fujitsu) with a client network (ALAXALA1

Networks and Keio University and OA Laboratory), 10-Gb/s-based transport multi-domain networks(NICT), an open disaggregated transport network (ODTN) network (NTT Communications and Infinera)
and an SDN-based data center network (NICT). The beyond 100-Gb/s-based network comprises twodisaggregated WDM nodes and an SDN controller (NTT Communications). Each node is equipped withbeyond 100-Gb/s optical transponders and 100-Gb/s Ethernet testers (Keysight Technologies) areconnected to the client interfaces of the transponders. In addition, an Ansible Tower (Red Hat) is setup inorder to control a Docker container application platform for acquiring sampled data from the beyond 100Gb/s optical transponder for classification of the incoming optical signal format using convolutional neuralnetworks. The client network comprises two core routers and three edge nodes (servers) with anorchestrator (orchestrating multi-layer (ML) network and VMs), which is located at the premises ofUniversity of Texas at Dallas (UT Dallas) in Texas, USA.

Figure 1 Showcase testbed configuration
The 10-Gb/s-based transport multi-domain networks comprise three 10Gb/s-based WDM network
domains that are located at the premises of NICT in Sendai, Japan and each network is controlled by each
SDN controller (KDDI Research, NTT Communications and NICT). The ODTN comprises opticaltransmission equipment and is controlled by an SDN controller.
The SDN-based data center network consists of servers controlled by an OpenStack controller (NICTand Red Hat), which cooperates with an SDN controller (KDDI Research).
In the control plane, three network orchestrators that are located in Japan (KDDI Research, NTT
Communications, and NICT) are connected to the SDN controllers that control the data planes. The
ansible master node and one of the orchestrators work together to control the container for acquiring
sampled data from the beyond 100-Gb/s transponder. The orchestrator at UT Dallas is connected to theclient network in Japan via the Internet VPN in order to control the network and VMs in servers and also2

routers.
Demonstrations(1) Data-Analytics-based Optical Performance Monitoring Assisted by Container Technique
Data-analytics-based technology has recently
beenintensively

studied.

Using

thistechnology for operating and optimizing
networks is gradually coming to be regarded
as an effective solution for large and complex
network environments. We
classificationofandemonstrateincoming

opticalmodulation format by a combination of
convolutional neural networks and SDNbased container technology.

(2) Dynamic Construction and Control of Virtual Network Platform Utilizing OpenStack
In order to achieve automatic adjustment of
VM resources in a virtual network responding
to some external events, NICT has been
designingandimplementing

autonomic

resource control architecture (ARCA), which
has been installed on a Red Hat OpenStack*1
Platform. In this showcase, we demonstrate avideo

servicethatmustbeadapted

dynamically (increase or decrease resources)by means of a virtual resource control requestfrom KDDI Research’s orchestrator after someexternal event occurs.

(3) Inter-Carrier Connection for Vital Traffic in the Event of a DisasterIn order to achieve rapid and low-cost recovery
in the event of a huge disaster, NICT, KDDI
Research and NTT Communications areworking

togetherandinvestigating

thetechnology for enabling the inter-carrier
collaboration in the post-disaster recovery
phase. In this showcase, we experimentallydemonstrate the rapid creation and control ofan emergency shareable exchange network(ESEN) between network carriers to convey
the highest priority traffic, i.e., vital traffic forvictim relief after a disaster.

(4) Open and Disaggregated Transport Network (ODTN)Open and Disaggregated Transport Network(ODTN) is an open project for designing thereference open architecture and the open source
solution where available open components areintegrated and tested for disaggregated transport
networks. It aims to help world-wide service
providers to use disaggregated devices and openmodels/controllers for their services. In thisshowcase, we demonstrate the latest architectureand solution using Transport API (Northbound Interface [NBI]), Open Networking Operating System(ONOS) (SDN Controller), OpenConfig (Southbound Interface [SBI]) and open transport devices providedby Infinera.
(5) Dynamic VM migration with dynamic ML-network configuration for ADV
A

network-controlledautonomous

driving

vehicle (ADV) with high mobility is one of therelevant applications for smart communications.
Close coordination of Cloud, edge, and local
computer resources is required. For example, a10-ms response time between the ADV’s board
computer and edge servers is required, which
includes both communication and processing
time. To meet this tight requirement, a dynamicedge processing system with VM live migration
is proposed. The ADV has three agents running in the edge servers, which provide service redundancy. Asthe ADV moves on the road one of the three agents at a time is live-migrated to another edge location inorder to satisfy the 10-ms response time requirement. This migration is realized by a dynamicallyreconfiguring the ML-network that interconnects the edge locations. Keio University provides the ADV
control application and the OpenStack-based VM environment. ALAXALA Networks provides thereconfigurable router, which includes a reconfigurable service module board with VM hypervisor capability.
UT Dallas provides the resource orchestrator which has ML-network reconfiguration and OpenStack VM
management capabilities combined.
(6) Optical Slot Switching System using Ether TDM Translator
Optical data-center networks are attractive forachieving energy efficient data-centers. The opticalslot switching (OSS) technology has been paid
attention. OA Laboratory and Keio University are
members of the HOLST (high-speed optical layer 1
switch system for time slot switching-based opticaldata center networks) projects. In this demonstration,
recently developed 10 Gbps Ethernet to OSS converter(Eth_TDM translator) is presented. The server
provides mixed flows to 2 destinations, the Eth_TDM translator provides OSS slots for each destination,
4and the PLZT (Plomb Lanthanum Zirconate Titanate) optical switching system distributes incoming OSS
slots to destination ports.
