Is It Time for Open Source SD-WAN?

Cisco ties its security/SD-WAN gear with Teridion’s cloud WAN service

Cisco and Teridion have tied the knot to deliver faster enterprise software-defined WAN services.The agreement links Cisco Meraki MX Security/SD-WAN appliances and its Auto VPN technology which lets users quickly bring up and configure secure sessions between branches and data centers with Teridion’s cloud-based WAN service. Teridion’s service promises customers better performance and control over traffic running from remote offices over the public internet to the data center. The service features what Teridion calls “Curated Routing” which fuses WAN acceleration techniques with route optimization to speed traffic.To read this article in full, please click here

Qualcomm loses case about its mobile-chip licensing fees

Chip maker Qualcomm has lost a round in federal court over how much it charges makers of wireless devices for its mobile chips.The company must lower its fees and submit to seven years of monitoring by the Federal Trade Commission, which brought the suit. Qualcomm says it will appeal.For more details about the suit and its impact on upcoming 5G deployments, watch this TECH(feed) video.   More about 5g networks:To read this article in full, please click here

Study: Most enterprise IoT transactions are unencrypted

Of the millions of enterprise-IoT transactions examined in a recent study, the vast majority were sent without benefit of encryption, leaving the data vulnerable to theft and tampering.The research by cloud-based security provider Zscaler found that about 91.5 percent of transactions by internet of things devices took place over plaintext, while 8.5 percent were encrypted with SSL. That means if attackers could intercept the unencrypted traffic, they’d be able to read it and possibly alter it, then deliver it as if it had not been changed.To read this article in full, please click here

Online performance benchmarks all companies should try to achieve

There's no doubt about it: We have entered the experience economy, and digital performance is more important than ever.Customer experience is the top brand differentiator, topping price and every other factor. And businesses that provide a poor digital experience will find customers will actively seek a competitor. In fact, recent ZK Research found that in 2018, about two-thirds of millennials changed loyalties to a brand because of a bad experience. (Note: I am an employee of ZK Research.)To help companies determine if their online performance is leading, lacking, or on par with some of the top companies, ThousandEyes this week released its 2019 Digital Experience Performance Benchmark Report. This document provides a comparative analysis of web, infrastructure, and network performance from the top 20 U.S. digital retail, travel, and media websites. Although this is a small sampling of companies, those three industries are the most competitive when it comes to using their digital platforms for competitive advantage. The aggregated data from this report can be used as an industry-agnostic performance benchmark that all companies should strive to meet.To read this article in full, please click here

Edge-based caching and blockchain-nodes speed up data transmission

The combination of a blockchain-like distributed network, along with the ability to locate data at the edge will massively speed up future networks, such as those used by the internet of things (IoT), claims Bluzelle in announcing what is says is the first decentralized data delivery network (DDN).Distributed DDNs will be like content delivery networks (CDNs) that now cache content around the world to speed up the web, but in this case, it will be for data, the Singapore-based company explains. Distributed key-value (blockchain) networks and edge computing built into Bluzelle's system will provide significantly faster delivery than existing caching, the company claims in a press release announcing its product.To read this article in full, please click here

Benchmarks of forthcoming Epyc 2 processor leaked

Benchmarks of engineering samples of AMD's second-generation Epyc server, code-named “Rome,” briefly found their way online and show a very beefy chip running a little slower than its predecessor.Rome is based on the Zen 2 architecture, believed to be more of an incremental improvement over the prior generation than a major leap. It’s already known that Rome would feature a 64-core, 128-thread design, but that was about all of the details.[ Also read: Who's developing quantum computers ] The details came courtesy of SiSoftware's Sandra PC analysis and benchmarking tool. It’s very popular and has been used by hobbyists and benchmarkers alike for more than 20 years. New benchmarks are uploaded to the Sandra database all the time, and what I suspect happened is someone running a Rome sample ran the benchmark, not realizing the results would be uploaded to the Sandra database.To read this article in full, please click here

How Hard Is It to Manage Your Intent?

This blog post was initially sent to subscribers of my SDN and Network Automation mailing list. Subscribe here.

Remember the “every device configuration is really an expression of our intent” discussion? Forgetting the wrong level of abstraction (we mostly don’t want to deal with all the idiosyncratic stuff network devices want to see in their configurations) and box-oriented thinking caused by device-level intent for the moment, let’s focus on another aspect: how hard is it to manage your intent?

Experts: Enterprise IoT enters the mass-adoption phase

IoT in general has taken off quickly over the past few years, but experts at the recent IoT World highlighted that the enterprise part of the market has been particularly robust of late – it’s not just an explosion of connected home gadgets anymore.Donna Moore, chairwoman of the LoRa Alliance, an industry group that works to develop and scale low-power WAN technology for mass usage, said on a panel that she’s never seen growth this fast in the sector. “I’d say we’re now in the early mass adopters [stage],” she said.

The future of HCI

You may have noticed already but HCI has been on our minds lately. We’ve talked about it in-depth in our recent white paper and JR Rivers, Cumulus Networks co-founder & CTO, has shared more about it in relation to a network of pods in his on-demand webinar. JR will share more about his take in an upcoming Kernel of Truth podcast episode but in the meantime, we’ll get Naveen Chhabra’s, a senior industry analyst at Forrester, opinion on the future of HCI.

We sat down with him recently to discuss this and here’s what he had to say.

Question: Why is the network such a critical consideration in any hyperconverged infrastructure (HCI) deployment?

Let’s look at the major transformational projects the organizations globally are working on. One project that spans all organizations, verticals, and geographies is digital transformation. IT leaders upgrade or acquire new technologies to support these projects. One pertinent issue across a large percentage of projects is that these are still focused on technology silos.

Specific to HCI, organizations have successfully collapsed the compute and storage silo. Network infrastructure is still not integrated to the extent that it could and should be. Firms have the capability, via HCI, Continue reading

NGINX structural enhancements for HTTP/2 performance

Introduction

My team: the Cloudflare PROTOCOLS team is responsible for termination of HTTP traffic at the edge of the Cloudflare network. We deal with features related to: TCP, QUIC, TLS and Secure Certificate management, HTTP/1 and HTTP/2. Over Q1, we were responsible for implementing the Enhanced HTTP/2 Prioritization product that Cloudflare announced during Speed Week.

This is a very exciting project to be part of, and doubly exciting to see the results of, but during the course of the project, we had a number of interesting realisations about NGINX: the HTTP oriented server onto which Cloudflare currently deploys its software infrastructure. We quickly became certain that our Enhanced HTTP/2 Prioritization project could not achieve even moderate success if the internal workings of NGINX were not changed.

Due to these realisations we embarked upon a number of significant changes to the internal structure of NGINX in parallel to the work on the core prioritization product. This blog post describes the motivation behind the structural changes, how we approached them, and what impact they had. We also identify additional changes that we plan to add to our roadmap, which we hope will improve performance further.

Background

Enhanced HTTP/2 Prioritization aims to do Continue reading
