If You Worry About 768K Day, You’re Probably Doing Something Wrong

A few years ago we “celebrated” 512K day - the size of the full Internet routing table exceeded 512K (for whatever value of K ;) prefixes, overflowing TCAMs in some IP routers and resulting in interesting brownouts.

We’re close to exceeding 768K mark and the beware 768K day blog posts have already started appearing. While you (RFC 2119) SHOULD check the size of your forwarding table and the maximum capabilities of your hardware, the more important question should be “Why do I need 768K forwarding entries if I’m not a Tier-1 provider”

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
