The Fat Pipe - All Packet Pushers Pods

On today's sponsored Tech Bytes episode we talk with MidSouth Bank CIO Daniel Hereford about how he's using SD-WAN from Silver Peak to support the bank's transformation to a hybrid cloud model, while also improving network visibility and performance for mission-critical applications.

Today's Network Break analyzes Adtran's entry into the SD-WAN market, a new IBN product from Lumina Networks, the latest software upgrade from NTOP, Google's timeline for blocking HTTP elements in HTTPS sessions in Chrome, plus a couple of detailed follow-ups, and a Tech Bytes show.

Greg and Ethan are here today. Hi. Just us. We wanted to speculate on what the impact of 5G and private LTE might be over the next several months & years on enterprise wireless. That is, Wi-Fi.

As in, will you need a private Wi-Fi network with APs you lovingly hang from the ceiling after a careful site survey and artisanally painted heat maps, along side of clever SSIDs with their accompanying policies? Or will you be at the point where you can just dump much of that responsibility on your telco, and let them do all of that for you?

This is a thought exercise. We don’t have all of the answers here, but there’s a lot to think about, both from the telco and enterprise side. Greg and I will take both sides of the argument and roll these ideas around in our head.

5G is coming. Private LTE is real. Companies are coming out of stealth with offerings in this space, so it seemed like a good time to chinwag about this.

We discuss:

* Risks and benefits for telcos of 5G

* Risks and benefits for enterprises of 5G

* If 5G does take over for Wi-Fi, what does that transition look like?

* Where might you want to retain Wi-Fi?

5G And Enterprise IT Whitepaper – Packet Pushers Ignition (Membership required)

In this IPv6 Buzz episode we discuss IPv4 special address ranges, the reasons behind efforts to make them globally routable, and what impact this is likely to have on IPv6 adoption.

CI/CD. You’ve got a vague notion of what it might be. Then you're asked to help the dev team put together an automated delivery process for a cloud app. How you do get from CI/CD as a concept to making it a reality? That's the subject of today's Day Two Cloud podcast with guest Nathaniel Avery.

Network Break feasts on a variety of tech news including a new wireless protocol proposed by Amazon, Mellanox support for the SONiC NOS, Palo Alto Networks saying it will build an SD-WAN offering, a dip in cloud infrastructure spending, and more.

Amazon Sidewalk is a SDWAN-based LPWAN over internet using their extensive device portfolio as nodes in a new service. Apple U1 Wideband uses radio technology to improve device tracking, location services and possibly even more health detection capability.

LPWAN

The era of Low Power WAN has been bubbling away in the background for quite some time. The big money was in the smartphones and pushing cheap wireless PCs in a handheld glass slab format for the last ten years. That market is getting saturated and its time for companies to look at the next phase of network growth.

Low Powered WAN is a group of technologies operating in various unlicensed spectrums usually at sub 1Ghz frequencies. These frequencies have low data rates but excellent penetration.

Last week we saw LPWAN announcements from Amazon and Apple, lets consider what that means.

You’re listening to Tech Bytes, a short, sharp sponsored conversation where we grab a technology or concept and see how much juice we can squeeze out of it in about 15 minutes.

Our sponsor today is Arista Networks and we’re going to talk about how software quality and product integrity deliver value to customers.

Our guest is Doug Gourlay, VP and General Manager of Cloud Networking at Arista.

We discuss:

* Why software is more important than hardware in networking

* The operational and security issues that arise from software vulnerabilities

* How code quality affects patches and upgrades

* More

The following section from Doug Gourlay is included to provide context on the numbers discussed in the podcast:

A CVE is a Common Vulnerability or Exposure where a vulnerability is a ‘weakness in the code found in software that, when exploited, results in a negative impact to confidentiality, integrity, OR availability” and an exposure is a “mistake in software that allows access to information or capabilities that can be used by a hacker as a stepping-stone into a system or network.”

CVEs are maintained in an authoritative list by MITRE, under contract to the US Government through the Department of Homeland Security at https://cve.mitre.org.

The data discussed in this podcast was compiled from the MITRE CVE database.  The CVSS scores were compiled from the Forum of Incident Response and Security Teams (FIRST) CVSS scoring database.

As of this posting on 26 September 2019, since 1 January 2014 there have been:

* 137 CVEs on Cisco NX-OS

* 217 CVEs on Cisco IOS

* 203 CVEs on Cisco IOS-XE

* 72 CVEs on Cisco IOS-XR

* 5 CVEs on Arista EOS

Software is essential to networking and on today's Tech Bytes podcast, sponsored by Arista, we examine how software quality affects operations, upgrades, security and more. Our guest is Doug Gourlay, VP and General Manager of Cloud Networking at Arista.
