0905 Keynote: Some thoughts on the Internet of Things

This presentation attempts to place the recent hype about the Internet of Things into a broader perspective with regards to the evolution of computers and networking. We explore the implications relating to the issues of quality and manageability in a world of essentially unmanaged devices.

Are we ready for such an environment? What can we learn from recent events that illustrate some of the risks we might encounter in such an environment?

Scaling data centre bandwidth with 400G and 800G Ethernet

Data centre bandwidth requirements are growing at an exponential rate with the shift to Serverless Computing, Machine Learning, and Artificial Intelligence.

25/50/100Gbps connectivity are currently the most economical ways to meet such demand. In this presentation, we go further by looking at 400/800Gbps technologies and trends to cope with even greater bandwidth demand post 2017.

1055 Disaggregation for Data Centre interconnections – Is it real or not?

The concept of disaggregation, ie, separating data centre equipment into separate components, particularly at the optical layer has been debated, questioned and evaluated by Internet Content Providers (ICP), Carrier Neutral Providers (CNP), Internet eXchange Providers (IXP) and Communication Service Providers (CSP) for the past 2–3 years.

Where are we now? Has anyone implemented this concept in a production network? Or is that just a hype?

In this presentation, Dion will provide market updates and his views based on his interaction with the ICP/CNP/IXP/CSP communities in Asia.

1235 Lunch
1345 Network automation (NetDevOps) with Ansible

The word Automation is widely used in the Systems world. Systems Administrators are familiar with the term DevOps which makes their lives easier.

On the other hand, Network Engineers are still configuring devices manually—copying and pasting from text editors—and the challenges associated with working in this manner: typos, configuration errors, manual backups and slow deployments etc.

This presentation is about mitigating these challenges through NetDevOps using Ansible, an open-source automation tool. Using real life practical examples, the presentation will include the basics of using Ansible through a 10/15-minutes live demonstration based on Ansible and GNS3.

1500 Experience of IPv6 Introduction in JapanIPv6 adoption has always been a challenge. In Japan, the government works very closely with the private sector in enabling broadband connectivity and in promoting the widespread use of IPv6.

While much of IPv6 deployment has been in fixed-line Internet thus far, mobile operators have gradually caught up and all mobile operators in Japan are now IPv6 compliant.

This presentation discusses about broadband in the IPv6 era—its status in broadband networks and issues observed when deployed in Japan, APAC and elsewhere in the world.

There are two parts in this presentation.
