Technologies for Various Applications

Figure: Showcase network layout
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 of available
network resources via more automation (e.g. SDN) and increased flexibility of the networks (e.g. Virtualization)in order to mitigate CAPEX and OPEX in the communication networks. In the showcase, SDN and network
virtualization technologies for various applications are demonstrated. Below is a showcase network
configuration including following items:(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 vital traffic in the event of a disaster(4) Open and disaggregated transport network (ODTN)(5) Dynamic virtual machine (VM) migration with dynamic multi-layer-configuration for autonomous
driving vehicles (ADV)(6) Optical Slot Switching (OSS) system using Ether TDM Translator.

(1) Data-analytics-based optical performance monitoring assisted bycontainer technique

Data-analytics-based technology has recently come under intensive study.
Using this technology for operating and optimizing networks is gradually
coming to be regarded as an effective solution for large and complex
network environments. We demonstrate classification of an incoming
optical modulation format by a combination of convolutional neuralnetworks and SDN-based container technology.

Booth #7

(2) Dynamic Construction and Control of Virtual Network Platform UtilizingOpenStack
Booth #11

In order to achieve automatic adjustment of VM resources in a virtual network
responding to some external events, NICT has been designing andimplementing autonomic resource control architecture (ARCA), which has
been installed on a Red Hat OpenStack Platform. In this showcase, we
demonstrate a video service that must be adapted dynamically (increase ordecrease resources) by means of a virtual resource control request from KDDI
Research’s orchestrator after some external event occurs.
(4) Open and Disaggregated Transport Network (ODTN)

To achieve rapid and low-cost recovery in the event of a major disaster,NICT, KDDI Research and NTT Communications are working together andinvestigating the technology needed to enable inter-carrier collaboration in
the post-disaster recovery phase. In this showcase, we experimentallydemonstrate the rapid creation and control of an emergency shareable
exchange network (ESEN) between network carriers to convey the highest
priority traffic, i.e., vital traffic for victim relief after a disaster.

Booth #3 and #5

Booth #6 and #4

Open and Disaggregated Transport Network (ODTN) is an open project for
designing reference open architecture and open source solutions whereavailable open components are integrated and tested for disaggregatedtransport networks. It aims to help world-wide service providers to use
disaggregated devices and open models/controllers for their services. In thisshowcase, we demonstrate the latest architecture and solution using
Transport API (NBI), ONOS (SDN Controller), OpenConfig (SBI) and opentransport devices provided by Infinera.
(6) Optical Slot Switching System using Ether TDM Translator Booth #3 and #8

A network-controlled autonomous driving vehicle (ADV) with high mobility
is one of the important application for smart communications. Cloud, edge,and local coordination is required. To do this, a 10-ms response time
between the ADV’s computer and edge computers is required including
communication and processing time. To meet this requirement, a dynamicedge processing system with VM live migration is proposed. The ADV has 3
agents in the edge computers. As the ADV is moving, one agent forestallingto keep 10-ms response time. This is realized by a dynamic ML-network
reconfiguration and dynamic VM migration. Keio University provides theADV control application and the OpenStack-based VM environment.
ALAXALA Networks provides the reconfigurable router, which includes areconfigurable service module board with VM hypervisor capability. UTD
provides the orchestrator, which has an ML-network reconfiguration andOpenStack VM management capabilities.

Optical data-center networks are attractive for achieving energy efficientdata-centers. The optical slot 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, a 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, and the PLZT (Plomb Lanthanum
Zirconate Titanate) optical switching system distributes incoming OSS slots todestination ports.
