IPv6 Buzz 083: The IPv6 Interface Identifier
In this IPv6 Buzz podcast episode we geek out about the IPv6 Interface Identifier (IID, i.e., the lower 64 bits of an IPv6 address reserved for interface identification). We discuss why IID is 64 bits, typical configurations, and innovative uses for it.

Its not widely that DDOS attacks also cause damage from state exhaustion in devices. A recent study why Netscout surprised me that many engineers are aware of overload bandwidth or routing devices but give less considerations to state exhaustion in application aware devices.

Kris Nóva, Senior Principal Software Engineer at Twilio, claims that managing infrastructure using tools like Terraform isn't that far away from just writing your own code to do the job yourself. Kris joins co-hosts Ned Bellavance and Ethan Banks to challenge the notion that ops folks can't become developers. Kris says they can.

Tech Bytes: DDOS and State Exhaustion With Netscout Arbor
Its not widely that DDOS attacks also cause damage from state exhaustion in devices. A recent study why Netscout surprised me that many engineers are aware of overload bandwidth or routing devices but give less considerations to state exhaustion in application aware devices.
Firewalls, IPS and reverse proxies are subject to overload failure when the internal state is exceeded. This includes server side caches (Varnish, memcache etc) and all this elements should be part of your DDOS strategy.
Roland Dobbins talks about the nature of these attacks and how to implement stateful protection while using stateless DDOS technology.

Network Break 346: Extreme Gets SDWAN, Huawei Struggles and SpaceX Swarms
The world of virtual donuts is supply constrained. Extreme Networks finally gets SDWAN buying Ipanema from Infovista at a bargain price. Research firms that does the numbers Dell'oro pitches that Education and Government markets will be spending big on WiFi6E - we aren't so sure that campus spending will be big just some spending but Dell'oro told us that government economic stimulus is the driver. Most will focus on distributed work.
Huawei posted 29% revenue reduction as the trade sanctions impact their overall business. A reminder that political solutions are slow if you have to make plans. And in space networking, SpaceX acquires pico-satellite company Swarm for IOT networking.

On today’s Heavy Networking, we drill into VMware’s vRealize Network Insight (vRNI) to learn how it provides end-to-end monitoring, how it uses flow records and other data sources, and its architecture. We’ll also discuss modeling/digital twin capabilities, and applying vRNI to security, troubleshooting, and other use cases. VMware is our sponsor.
