Q4: What issues are you seeing—and solving or NOT solving—in networking development?
Tony Cai - Nerdio
A4: Low latency broadband to rural areas and business, its not happening fast enough. Technologies like Windows Virtual Desktop requires minimum dropped packets and under 200ms consistently.

Charles Cheevers
Q4: For CommScope we are building the physical connectivity in the core/enterprise with our wired solutions and switches, we are building the networks that connect the 5G Small Cells as well as the Radios that send new 5G NR to the growing masses
Matt
@TonyCai Certainly an area of focus for us @CambiumNetworks
Charles Cheevers
Q4 - At the same time we are also building out the next generation HFC and DOCSIS networks for 10G/DOCIS 4.0 capacity to the home with our CMTS and Fiber Nodes as well as providing DOCSIS to PON transition technologies for the homes and businesses that need 10Gbps
Sivan Tehila
A4: Lack of scalability and visibility. These are two issues we frequently see and are helping our customers with as they depart from legacy solutions.

A4: It's been amazing to see how organizations have almost instantaneously moved to a work from home workforce. We've seen very creative use of Wi Fi, encryption/VPN and identify-based access control deliver the corporate network to the home and do it securely.
Matt
@CheeversCharles A4: Many rural areas, however, are not served by MVNO and SPs, due to the risky financials... which is where #FixedWireless services may be a better fit
Charles Cheevers
We are also in a unique position in that we also develop the end devices in most of the homes in the US and across the globe - from DOCSIS and PON GW , Wi-Fi Access Points and Mesh solutions and STB and Smart Media Devices - so we really understand the e2 experience
Amy Abatangle
A4: I’m interested in seeing how #edge, #5G, and #Wifi6 could help with the last mile problem, especially in low-density geographies.
Amy Abatangle
A4: I’m also still amazed by how many organizations struggle with #networksecurity. It’s a mindset as much as it is a question of technology choices, and it has to be there in the planning stages instead of bolted on later.
Charles Cheevers
@CambiumMatt Absolutely....and we will be happy to run fiber to your FWA solutions as well for interconnect backhaul... Hopefully lots of Ruckus and Cambium systems filling the void of 16M US consumers with less than 25/5 Broadband
Charles Cheevers
@AAbatangle Wi-Fi 6E spectrum with Standard Power SAS controlled at 2W or greater can be an effective way of getting a single Fiber POP quickly to the last mile...
Amy Abatangle
@CheeversCharles Now we've just got to see the financial incentive/commitment to do it.
Stateless
A4 Even though we have seen incredible advances in software networks are still built with a device centric mindset. "We need a firewall for that or a router for this". We don't need more devices. We need to be able get the network functions we want.
Larry Lunetta
The best way to secure a distributed workforce is to use the same access policies and enforcement as if they were still physically in the office.
Tony Cai - Nerdio
I had a partner sell a virtual desktop solution last month, and upon additional discovery, I discovered they were using satellite technology and wanting to run 15 desktops via a high latency 3MBPS connection in Ohio. As much as I wanted to close the deal, wasnt worth the issues.
Charles Cheevers
@TonyCai Yes - we need to be able to provide consistent latency to 15ms for all broadband consumers.... Latency is THE new currency.... more important to have services work snappy than to go from 200Mbps to 300Mbps SLA on Broadband... Although Gbps bursts do help with jitter too
Chris Preimesberger
Sidebar to Q4: To what extent is the WFH trend impacting your business directly?
Amy Abatangle
A4: @linuxnetdata was founded as a fully remote, global company, so zero new impact. That being said, remote-only collaboration has its challenges, and we were disappointed to have to skip our company meetup this year due to #covid travel restrictions.
Tony Cai - Nerdio
Huge! At @Nerdio we enable partners and customers to deploy Windows Virtual Desktops from Azure, and adoption has accelerated through the roof from everyone wanting to securely access their corporate apps and desktops over the WAN. We are seeing customers ditch their offices.
Stateless
Q4 Sidebar - WFH is forcing every business to re-evaluate their infrastructure. It has been good for us because Stateless is all about making the creation of networks simple and fast.

Matt
Supplement to A4: Demand for #FixedWireless networking equipment has never been higher (or more urgent). Many companies are discovering that this is the "new normal", and WISPs and traditional Service Providers are struggling to keep up with demand for #wfh bandwidth
Tony Cai - Nerdio
@AAbatangle True, I miss live events!!
Chris Preimesberger
I live near Facebook in Menlo Park, Calif., and have been watdching the company build dozens of new buildings with more than 1M square feet of office space. Few people are in them now and I'm wondering how many will return to work there. Wow.
Charles Cheevers
Its been huge .. We have seen over a years growth in traffic on the access network. New norms of peaks during the 8-5 Video Conferencing WFH window..... Lots more Uplink traffic from the home as people try and perform same functions at home as in the office
Larry Lunetta
On the positive side, our remote access solutions are flying off the shelf as well as the contact tracing solutions that will facilitate a safe return to the office. Like all organizations, we are continuing to learn what remote working means.
Charles Cheevers
Opportunities for new WFH services and packages... Do you want to always be the one person with the poor performing Video conference
Charles Cheevers
Wi-Fi IS THE INTERNET for WFH
Amy Abatangle
@stateless_inc Yes, we've seen accelerated adoption of @linuxnetdata IT infrastructure monitoring since February, driven by the need for enhanced #observability thanks to the pressures remote work is putting on systems & apps.
Matt
Note: @CambiumNetworks actually provided software to enable 45 MHz of additional unlicensed frequencies at the start of the COVID crisis to alleviate congestion and allow more subscribers to connect to their provider. (The @FCC graciously granted STA to many folks)
Charles Cheevers
Other than people running leaf blowers and lawnmowers in the middle of your most important conference or the kids running in - Wi-Fi is your WFH lifeline
Chris Preimesberger
I can identify ... my next-door neighbor is a carpenter and seems to use his rotary saw whenever I'm on on a business call of any kind!

Q3: What is intent-based networking and what are its business advantages? Is your company using this?

Understanding the Key Trend of Intent-Based Networking
Understanding the Key Trend of Intent-Based Networking
TREND ANALYSIS: During the next several years, the IT industry will see a rise IBN vendors; some that address part of the solution and others that are end to end.
Amy Abatangle
A3: I think that intent-based networking is an evolution of SD-WAN, but sounds like marketecture more than anything else right now; the paradigm makes sense, but it's early. Still haven't seen the full potential of SD-WAN outside the enterprise.
Tony Cai - Nerdio
I had to read the article as I was not familiar with the term, so its basically AI networking governed by the IT administrator.
Chris Preimesberger
Marketechture! Love it
Stateless
A3. Intent based networking is the mixture of data science and data communications. It has huge potential as tech is produced that allows networks to become 'aware' of the data that they are carrying. There's a lot of promise in this tech.
Stateless
The network needs to be more programmable before we see true 'intent-based' networking apps.
Chris Preimesberger
Q5: How is SD-WAN able to converge network, security and AI all in one?
Tony Cai - Nerdio
SDWAN providers will pass traffic from different ISP providers through a virtual managed firewall and perform DPI, filtering, etc all from a centralized location.
Larry Lunetta
If you can see the traffic and understand its flow, then connectivity choices, security and AI-powered optimizations naturally follow. The management and aggregation of all of this in the cloud makes it practical.
Amy Abatangle
A5: Intelligent pathing with SD-WAN makes it easier to vector suspect traffic for further processing, moving the burden off of endpoints to a greater degree.
Stateless
A5. I think it's not SD-WAN pre se. We're seeing more programmability being introduced into networks. Tech like P4 which allows us to now use software to control layer 2. Software control is allowing us to raise the level of intelligence of the network.
Tony Cai - Nerdio
The Windows Virtual Desktop Control Plane in with ExpressRoutes Azure is the perfect example of how they converge networking, security all in one utilizing their global footprint. #wfh #wvd
Charles Cheevers
We have been working with Service providers to sell Business services using SD-WAN services and solutions. Its the effective and fast way to stand up services but more importantly to easily pick and choose more
Charles Cheevers
Like Enterprise Wi-Fi solutions have now drifted to the Home Wi-Fi mesh solutions ... we also see in the not too distant future - uCPE enabled SD-WAN like services will also leverage the home edge to enable services to consumers on a new uCPE home compute platform...
Charles Cheevers
In the meantime we will be dropping containerized services into Residential GW and AP devices to enable the first batch of new home services from Firewalls to IoT hubs to Wi-Fi motion and other services
Amy Abatangle
@CheeversCharles They already exist, and the demand will only scale with #Wifi6 and the glut of devices on home networks. Home routers need to be a lot smarter.
Chris Preimesberger
Sudden thought on Q1: Will we eventually have powerful enough WiFi to handle VR and AR on our home networks?
Charles Cheevers
Yes - Wi-Fi 6E - 66Gbps of potential
Zeus Kerravala
Both #5G and #WiFi6 will bring wireless speeds up to par with wired... Wired versus wireless is no longer a choice... #VR and #AR will run fine over WiFi
Charles Cheevers
Scope to even do HDMI over 6E but will still be lightly compressed to fit into 4x4 - 4.7Gbps initially
Stateless
Absolutely. One thing that the network has been always been able to do is go faster! But will the WAN infrastructure get the RIGHT data to your doorstep?
Matt
#wifi6 can certainly handle VR applications
Charles Cheevers
@zkerravala VR at 8K or even 4Kp60/120 which is what we need does not run well over Wi-Fi 5 today.... Sure there are some VR Googles and Phones in boxes - but thats not where VR needs to be...needs either Wi-Fi 6E or 60GHz to really have the latency and b/w required for 10ms
Amy Abatangle
@stateless_inc @editingwhiz That's the real question, along with the realistic demand for consumer VR/AR apps. It hasn't really materialized yet.
Tony Cai - Nerdio
@CheeversCharles any health concerns around so many radio signals through the air? I always wondered how the SAR scale on mobile phones correlate with wifi AP's in homes and businesses.
Charles Cheevers
We are making sure that the power levels are appropriate for home use...so should be good... In fact we define the 6E level as Low Power Indoor mode - so that it wont interfere with Fixed Links using 6GHz today.. We have also specified a Very Low Power 25mW mode
Charles Cheevers
@CambiumMatt Not if your in an MDU with 5GHz congestion - thats what the new spectrum at 6GHz is for... You can almost have your own channel per apparment ... with 7 160MHz channels and 14 x 80MHz...
Matt
@CheeversCharles Agree that 6 GHz opens a new swath of usable spectrum to alleviate congestion and utilize faster connections.
