Orbital edge computing: nano satellite constellations as a new class of computer system

Orbital edge computing: nanosatellite constellations as a new class of computer system, Denby & Lucia, ASPLOS’20.

Last time out we looked at the real-world deployment of 5G networks and noted the affinity between 5G and edge computing. In true Crocodile Dundee style, Denby and Lucia are entitled to say “that’s not the edge, this is the edge!”. Today’s paper choice has it all: clusters of formation-flying autonomous nanosatellites working in tandem to overcome the physical limitations of space and the limited bandwidth to earth. The authors call this Orbital Edge Computing in contrast to the request-response style of satellite communications introduced with the previous generation of monolithic satellites. Only space system architects don’t call it request-response, they call it a ‘bent-pipe architecture.’

Momentum towards large constellations of nanosatellites requires a reimagining of space systems as distributed, edge-sensing and edge-computing systems.

Satellites are changing!

Satellites used to be large monolithic devices, e.g. the 500kg, $192M Earth Observing-1 (EO-1) satellite. Over the last couple of decades there’s been a big switch to /nanosatellite/ constellations. Nanosatellites are typically 10cm cubes (for the “CubeSat” standard), weigh just a few kilograms, and cost in the thousands of dollars.

Heavy Networking 543: What 2020 Internet Outages Teach Us About Managing Remote Work (Sponsored)

Stuff breaks all the time. With so many people working from home, most of the stuff that's breaking isn't yours, but that doesn’t mean it’s not your problem. Today's Heavy Networking, sponsored by ThousandEyes, reviews critical outages in 2020 and considers network design tips for Internet and remote work. Our guests from ThousandEyes are Angelique Medina and Archana Kesavan.

When Will You Need Wi-Fi 6E at Home?

The pandemic has really done a number on most of our office environments. For some, we went from being in a corporate enterprise with desks and coffee makers to being at home with a slightly different desk and perhaps a slightly better coffee maker. However, one thing that didn’t improve was our home network.

For the most part, the home network has been operating on a scale radically different from those of the average corporate environment. Taking away the discrepancies in Internet speed for a moment you would have a hard time arguing that most home wireless gear is as good or better than the equivalent enterprise solution. Most of us end up buying our equipment from the local big box store and are likely shopping as much on price as we are on features. As long as it supports our phones, gaming consoles, and the streaming box we picked up we’re happy. We don’t need QoS or rogue detection.

However, we now live in a world where the enterprise is our home. We live at work as much as we work where we live. Extended hours means we typically work past 5:00 pm or start earlier than 8:00 or Continue reading

How to Optimize IT Costs

You do not need to sacrifice quality for a cheaper solution to save your IT department’s costs. Sometimes an optimization of infrastructure management will be sufficient. Alexander Grishin, ISPsystem’s Product Manager for VMmanager virtualization platform, shares his views on the topic.

Hand and Physical Therapy Tips for Arthritis

Millions of people all over the world suffer from arthritis. In the present day, it is one of the most common medical conditions in the world. There is a common misconception about arthritis that it happens due to old age and that most people suffering from it are old. Where old age can affect your bones and joints health, people from all age groups can suffer from arthritis.

What Exactly Is Arthritis?

It is a medical condition that causes pain and inflammation in your joints. It can happen on joints on any part of the body. It can cause severe pain and affect your physical functioning. People who have arthritis in their hand joints have to tolerate excruciating pain. Our hands are something we have to use on a daily basis, and when you have arthritis in your hand joints then it can have severe consequences. You will not be able to perform any task if your hands aren’t at 100% health.

How Can Physical Therapy Be Used to Treat Arthritis?

There are many ways that arthritis can be treated. Doctors would always suggest medication and then ask you to focus on physical therapy as well. Physical therapy is as Continue reading

PCAP Or It Didn’t Happen

The packet capture is the one tool in the network engineer’s pocket that doesn’t lie. Or does it? In this episode we talk about the fundamental components of packet captures and how to use them effectively in troubleshooting and managing your network.

It’s also time for the NetDevOps survey. Whether you’re someone who utilizes automation as a fundamental tool of your network or someone who is just thinking about starting an automation journey, your input is needed. Please take a few minutes to fill out the NetDevOps Survey.

 

Network Collective thanks NVIDIA for sponsoring today’s episode. NVIDIA is positioned as the leader in open networking and provides end-to-end solutions at all layers of the software and hardware stack. You can experience NVIDIA Cumulus in the Cloud for free!  Head on over to:

Pondering That Rumored $30 Billion AMD Acquisition Of Xilinx

You can have a strategy, but you can’t buy one.

Nothing illustrates this principle more than the networking buying binges that both Intel and AMD went on nearly a decade ago, which did not really amount to much in the end but which made some sort of sense in the middle of it all happening.

Exploring WebAssembly AI Services on Cloudflare Workers

Exploring WebAssembly AI Services on Cloudflare Workers

This is a guest post by Videet Parekh, Abelardo Lopez-Lagunas, Sek Chai at Latent AI.

Edge networks present a significant opportunity for Artificial Intelligence (AI) performance and applicability. AI technologies already make it possible to run compelling applications like object and voice recognition, navigation, and recommendations.

AI at the edge presents a host of benefits. One is scalability—it is simply impractical to send all data to a centralized cloud. In fact, one study has predicted a global scope of 90 zettabytes generated by billions of IoT devices by 2025. Another is privacy—many users are reluctant to move their personal data to the cloud, whereas data processed at the edge are more ephemeral.

When AI services are distributed away from centralized data centers and closer to the service edge, it becomes possible to enhance the overall application speed without moving data unnecessarily.  However, there are still challenges to make AI from the deep-cloud run efficiently on edge hardware. Here, we use the term deep-cloud to refer to highly centralized, massively-sized data centers. Deploying edge AI services can be hard because AI is both computational and memory bandwidth intensive. We need to tune the AI models so the computational latency and bandwidth Continue reading

Faucet Deep Dive on Software Gone Wild

This podcast introduction was written by Nick Buraglio, the host of today’s podcast.

In the original days of this podcast, there were heavy, deep discussions about this new protocol called “OpenFlow”. Like many of our most creative innovations in the IT field, OpenFlow came from an academic research project that aimed to change the way that we as operators managed, configured, and even thought about networking fundamentals.

For the most part, this project did what it intended, but once the marketing machine realized the flexibility of the technology and its potential to completely change the way we think about vendors, networks, provisioning, and management of networking, they were off to the races.

We all know what happened next.
