Packet Pushers - Priority Queue

Ruru is open source software for monitoring TCP latency in real time. As it says on the project’s GitHub page, the software “utilizes Intel DPDK for high speed packet processing (up to 40Gbit/s) and a Node.JS web frontend to present results.”

On today’s Priority Queue we talk with Ruru developer Richard Cziva. We dive into how Ruru works, what insights we can glean from the data Ruru generates, and how the application scales.

We also discuss roadmap items and how developers and non-developers alike can contribute to the project.

Last but not least, we answer the burning question “What the heck is a Ruru?” (It’s an owl native to New Zealand and Tasmania, and also known as a Morepork.)

DDoS attacks are tricky to detect and hard to defend against. But the chances are good that you’ll be a victim of a DDoS attack either directly or indirectly at some point in your IT career.

FastNetMon is DDoS detection software available both as open source and in commercial versions. On today’s Priority Queue we’ll explore the open-source version, look at how it works, examine its capabilities, and discuss hardware requirements.

We’ll also look at how it can use BGP black holes and BGP Flowspec to help mitigate DDoS attacks.

Our guest is Pavel Odintsov, FastNetMon’s project leader.

FastNetMon recently added IPv6 support in the Advanced (commercial) version.

Today on the Priority Queue, OPNsense wants to be your next open source firewall.

The project’s trademark is “High-end security made easy.” Interested? Good, because I’ve got Franco Fichtner from the OPNsense core development team here to talk about it.

We discuss why OPNsense was forked from the pfSense and m0n0wall projects several years ago, and then jump into technical features including high availability, routing capabilities, traffic shaping, and more.

We also talk about monitoring and reporting capabilities, troubleshooting, and the project’s roadmap.

In late 2017 AT&T released a white paper outlining the company’s vision for a “Disaggregated Network Operating System” or dNOS.

According to AT&T, dNOS aims:

* To be network OS separate from the underlying hardware that runs on multiple platforms including merchant networking silicon and x86

* To have standardized APIs and other interfaces for clean separation of the control plane and data plane

* To provide a platform to integrate with existing tools and applications and spur the development of new ones

On today’s Priority Queue, John Medamana, AT&T Fellow and Vice President, Packet & Optical Networks at AT&T, joins us to share more information about this project.

We talk about why AT&T is driving this effort, what the company hopes to achieve, and where they are in the process.

Note that after this podcast was recorded, AT&T announced it was moving the dNOS project to the Linux Foundation.

John is co-author of Building the Network of the Future: Getting Smarter, Faster, and More Flexible with a Software Centric Approach. You can also follow him on Twitter at @johnmedamana.

Today’s Priority Queue delves into Open vSwitch with guest Ben Pfaff, an Open vSwitch contributor for the past ten years.

As you might infer from the name, Open vSwitch is open source software that provides switching capabilities and can run in a hypervisor, on bare metal servers, in containers, and on NICs.

You can program OVS directly or via a controller such as OpenDaylight or a commercial controller.

Open vSwitch is a project within the Linux Foundation.

This podcast was recorded live during a meeting with Ben in which he recorded a podcast with me, which you can find at OVS Orbit.

We discuss an overview of OVS, explore key features, and examine how OVS applies to the enterprise. We also look at the relationship between SmartNICs and OVS, and discuss how OVS works with service meshes.

If you want to learn more about OVS, check out Ben’s podcast at OVS Orbit.

Welcome to Packet Pushers. In today’s sponsored show, we are talking with WhiteSpider with some stories from the field.

We’re joined by smart engineers implementing real technology, and we’ll get in the trenches to discuss customer deployments of Cisco ACI and SD-Access.

Joining us today are Jonathan Perrozzi, Head of Architecture, WhiteSpider; Phil Lees, CTO at WhiteSpider; and Max Ardica, Principal Engineer from Cisco.

The podcast takes a detailed look at real-world customer experiences of deploying ACI, exploding the myth that ACI is complex. We also examine how ACI is transforming IT operations in these organizations. The podcast also looks at how Cisco’s SD-Access takes ACI constructs and applies them to the campus network.

Today's Priority Queue, sponsored by Ribbon Communications, examines how to make the transition from Skype for Business to Microsoft Teams, and how Ribbon's Session Border Controller (SBC) can help.

Today on this sponsored episode of Priority Queue: making the transition from Skype for Business to Teams, a chat and collaboration platform from Microsoft. Teams runs on Azure and integrates with Office 365.

Our sponsor is Ribbon Communications, which is the new name of the combined companies Sonus Networks and Genband.

Brad Chapin, Director of Strategic Alliances at Ribbon Communications, joins us to get nerdy about voice, collaboration, Skype, and Microsoft Teams.

We discuss the differences between Skype for Business and Teams, how Ribbon’s Session Border Controllers (SBCs) can help you integrate the two platforms even in a hybrid cloud environment, and how organizations can move from one platform to another while keeping existing phone numbers.

Today on the Priority Queue, we're talking about the book "Mastering Python Networking" by Eric Chou. We also cover Pythan, automation, Ansible, and other good stuff.

Today on the Priority Queue, we’re talking about the book Mastering Python Networking by Eric Chou. Eric also blogs at blog.pythonicneteng.com.

The book aims to help network engineers get more comfortable with automation, coding, and with tools such as Ansible.

Now, lest you think Eric wants you to buy his book so that he can buy a Ferrari, he’s donating all proceeds from the book to charity.

And Eric has a special offer for Packet Pushers listeners. The first 10 subscribers to Eric’s newsletter will get a free ebook version of Mastering Python Networking. And for everyone who subscribes, you’ll be entered in a drawing to win a free autographed copy of the book. Sign up here.
