3 The Janet Network during COVID-19

First things first -- I'm more than happy to drop this in favour of non-pandemic content.

Having said that, I've had a few observations on how our traffic has changed during working and studying from home, and what we're still doing to facilitate that (touching briefly on students of UK universities studying further abroad).

Draft slides from presenting something similar earlier this week are attached, but can be changed as required. As-is, this took 15 minutes and change.

4 Hyperlocal root & Localroot - Running a local copy of the DNS root zone

DNS(Domain Name System) is the crucial & ubiquitous fabric for the Internet. Despite the fact that there are 13 root servers (1084 instances in Anycast) all around the world, the resiliency & the security of the DNS has been an ongoing probing question. This presentation explores the following questions

How do we increase the resiliency of the root servers ?
How do we stop sending junk queries to the root servers ?
How do we reduce the access time to the root servers ?
How do we increase the privacy by hiding queries made to the root servers ?
RFC7706/8806 provides us answers to these questions. Plus, I will demonstrate an interesting project (Localroot) which allows anyone to run a local copy of the DNS root zone.

Speaker: Mr Swapneel Patnekar (Shreshta IT)

6 Level Up appeal - laptops and Internet access to disadvantaged children during the pandemic

I'll create some simple high level slides but this is the main content of the presentation:

Background and problem:

It’s become very apparent that the ‘new normal’ for school children now and in the future includes a considerable amount of learning at home using online resources. Unfortunately, some families can’t afford IT equipment to support their children studying at home, and right now these disadvantaged children are missing out. The government has made funds available to provide laptops and Internet access to some of these children, but that currently only includes children in social care which is a tiny fraction of the kids that need help.

After liaising with schools in my home town of Horley (population around 22,000), I believe there are around 100 children with an urgent need for IT equipment to help them with their school work.

What I've done:

To help address this problem, I’ve set up a laptop appeal to encourage individuals and businesses to donate unwanted laptops. I take the laptop in, clean it, generally replace the hard drive, occasionally install more memory (RAM), install Windows 10 or CloudReady ChromeOS and power test it. I then give the laptop to one of the Horley schools for onward distribution to the families that need it most. Using old laptops rather than buying new ones takes more work, but we're reusing existing equipment which is significantly cheaper than buying new laptops and is better for the environment.

Internet access:

For families that need it, I'm also providing Internet access using mobile SIMs and 4G dongles.

Data security concerns:

Rightfully some doners have concerns over the security of their data, especially if the laptop was used for business purposes. To solve this problem I'm happy to take laptops that have had their hard drive removed, or I'm happy to remove the drive for the owner. Older laptops typically have slower hard disks, so replacing the disk with a modern solid-state drive (SSD) is cheap, quick to install and significantly speeds up the laptop for the new owner.

Onward ownership of the device:

Each laptop includes a letter from me explaining the laptop is now theirs to do with as they wish. I don't expect the device back, but I do ask that if the laptop isn't required anymore and still functions well to please return to me or the school as it may benefit another child.

Call to action:

I need help please in a few different areas:

• Scale - I can't afford the time to do this outside of Horley, could you (the audience) start Level Up in your town?
• Internet access - SIMs and dongles are expensive, could your service provider help in providing these? Or are there any other ideas on how to offer cheap, short term internet access (like BT WiFi for example)?
• Laptops - I (and if we get this to scale, many others) need access to unwanted laptops - does your business have any they could spare please?

7 Scaling your metro: the journey from 100 to 400G

I'll talk about the journey for upgrading our metro infrastructure from mid-2010s era 10G DWDM through to multiples of 100G to 400G. How can we cost-effectively expand networks with high bandwidth demands with spans in the 1-80km range?

We can start with an overview of how we did things in the n*10G world and why this does not directly transition into 100G. Your technology and cost options for lighting 100G (direct detect / PAM4 / coherent) and why a timely migration to 400G technology might be an option.

8 MAC Randomisation - considering privacy features with unintended network consequences

This talk will outline the concept and history of device MAC randomisation, current phases and the potential for further enhancements and thoughts on considering privacy features with potential unintended consequences on the network and customer experience.

9 SD-WAN API's and Programmability

Starting with Postman collection examples on how to get started with Cisco vManage APIs then we will look at how to use vManage Aggregation APIs to generate reports on statistics related to loss/latency/jitter of SD-WAN overlay tunnels and we will also look at how to use APIs to trigger policy updates to change the preferred transport for certain application traffic. Finally we look at how to use Viptela Python SDK to simplify operations related to feature/device templates.
