Three years on air

Hello my friend,

Three years ago, on the 5^th June 2016, we have posted the first article about Nokia SR OS/ Cisco IOS XR interop. We can dispute, if it was long ago or not, but what we can’t dispute the amount of information shared with you since that time on various network and automation topics!

Over these three years we have posted 75 (seventy five!) articles about the design, configuration and implementation of the multivendor networks with Nokia SR OS, Cisco IOS XR, Arista EOS and Cumulus Linux. Out of that 75, the 21 articles were written in this third year. Thanks to the blog activity we were awarded as the CiscoChampion 2019 as a top tech influencers worldwide.

The last year was a kind of breakthrough, not only based on the topics we were covering, about which we’ll Continue reading

Do Packet Drops Matter for TCP Performance?

Approximately two years ago I tried to figure out whether aggressive marketing of deep buffer data center switches makes sense, recorded a few podcasts on the topic and organized a webinar with JR Rivers.

Not surprisingly, the question keeps popping up, so it seems it’s time for another series of TL&DR articles. Let’s start with the basics:

Data validation for machine learning

Data validation for machine learning Breck et al., SysML’19

Last time out we looked at continuous integration testing of machine learning models, but arguably even more important than the model is the data. Garbage in, garbage out.

In this paper we focus on the problem of validation the input data fed to ML pipelines. The importance of this problem is hard to overstate, especially for production pipelines. Irrespective of the ML algorithms used, data errors can adversely affect the quality of the generated model.

Breck et al. describe for us the data validation pipeline deployed in production at Google, “used by hundreds of product teams to continuously monitor and validate several petabytes of production data per day.” That’s trillions of training and serving examples per day, across more than 700 machine learning pipelines. More than enough to have accumulated some hard-won experience on what can go wrong and the kinds of safeguards it is useful to have in place!

What could possibly go wrong?

The motivating example is based on an actual production outage at Google, and demonstrates a couple of the trickier issues: feedback loops caused by training on corrupted data, and distance between data Continue reading

Technology’s Promise – Highlights from DEF CON China 1.0

DEF CON is one of the largest and oldest security conferences in the world. Last year, it launched a beta event in China in hopes of bringing the local security communities closer together. This year, the organizer made things official by introducing DEF CON China 1.0 with a promise to build a forum for China where everyone can gather, connect, and grow together.

Themed "Technology's Promise", DEF CON China kicked off on 5/30 in Beijing and attracted participants of all ages. Watching young participants test, play and tinker with new technologies with such curiosity and excitement absolutely warmed our hearts!

It was a pleasure to participate in DEF CON China 1.0 this year and connect with local communities. Great synergy as we exchanged ideas and learnings on cybersecurity topics. Did I mention we also spoiled ourselves with the warm hospitality, wonderful food, live music, and amazing crowd while in Beijing.

科技点燃未来，未来尽在指掌之间 — Cloudflare 与你共赏安全界 “奥斯卡” DEF CON China 1.0 大会

科技在发展，时代在进步，许多事情或许本质并没有改变，但呈现的方式已经日新月异，这或许就是我们常说的 — 未来。就像许多年前，我们还通过明信片和相册向亲友分享我们生活中的点点滴滴。许多年后，我们有了朋友圈、微博、Facebook、Instagram、抖音、各式博客。幼时还守着电视看着预录好的节目，接触外界的形形色色，现在我们透过直播的镜头，弹指间便能瞬息感受世界当下的脉动。

科技改变着我们，我们推动着未来

许多人都在电影中看到过极客指尖敲动，在数字的世界中急速驰骋的场景。然而现实生活中，这些人在哪儿不得而知。随着技术的发展，越来越多的年轻人加入了这个群体。在国外一直都有 DEF CON 这样的世界极客盛会。中国此前也还没有，直到去年 DEF CON 来到了中国，主办方斥巨资引进大会，想打造属于中国的技术社区，通过这样一个契机，将大家聚在一起，一同成长，最终构建一个属于中国自己的、真正的安全社区。于是，在 DEF CON 的名下，多了一个 DEF CON China。  

今年，DEF CON 经过一年的沉淀后，进入了正式版本 1.0，这个世界顶级的安全会议，在五月底，以 "Technology's Promise" — “科技点燃未来” 为主旨，于北京拉开了序幕，像是一位家长等待着 “孩子们” 一起过节。这个六一，还有什么能比来 DEF CON China 1.0 众乐乐更具意涵呢？

作为在中国地区的正式版本，DEF CON China 吸引了很多大咖前来参与，一直致力于网络安全的 Cloudflare，这次也前来共襄盛举，带来了最新的科技跟大家分享。

Data center workloads become more complex despite promises to the contrary

Data centers are becoming more complex and still run the majority of workloads despite the promises of simplicity of deployment through automation and hyperconverged infrastructure (HCI), not to mention how the cloud was supposed to take over workloads.That’s the finding of the Uptime Institute's latest annual global data center survey (registration required). The majority of IT loads still run on enterprise data centers even in the face of cloud adoption, putting pressure on administrators to have to manage workloads across the hybrid infrastructure.To read this article in full, please click here

5G will augment Wi-Fi, not replace it

There’s arguably no technology topic that’s currently hotter than 5G. It was a major theme of the most recent Mobile World Congress show and has reared its head in other events such as Enterprise Connect and almost every vendor event I attend.Some vendors have positioned 5G as a panacea to all network problems and predict it will eradicate all other forms of networking. Views like that are obviously extreme, but I do believe that 5G will have an impact on the networking industry and is something that network engineers should be aware of.To read this article in full, please click here

Orange Matter: All I Want For Christmas is RESTCONF

I’ve been blogging for Solarwinds recently, posting on Orange Matter, with a cross-post to the Thwack Geek Speak forum. I need clear commands, structured response data and simple access to it all; so how about giving me REST-based APIs on all my infrastructure equipment?

This post appeared on Orange Matter as “All I Want For Christmas is RESTCONF“, but I’m also linking to the version posted on Thwack, in case you prefer to read and comment there.

I’d love it if you were to take a moment to visit and read, and maybe even comment!
