Netflix has announced that they are deploying their own Content Delivery Network (CDN) for delivery of their video streams to Internet Exchange Points (IXPs) around the world. More importantly they are making the hardware and software design of their CDN servers freely available. That means any network can deploy Netflix CDN boxes deep into their network to significantly reduce traffic volumes and improve performance for users. more
We are suffering an epidemic of cyberattacks while in a viral pandemic. This post is for those who have responsibility for assuring that the IT-based services offered by their enterprise can quickly recover in the case of successful cyber-attack or other disaster. University of Vermont Medical Center (UVMMC) is an excellent hospital. I owe my life to treatment there and am grateful for both the skill and the kindness of UVMMC staff. They have been devastated by a cyber-attack. more
BGP. Border Gateway Protocol. The de-facto standard routing protocol of the Internet. The nervous system of the Internet. I don't think I can overstate the importance, the criticality of BGP to the operation of the modern Internet. BGP is the glue that holds the Internet together at its core. And like so many integral pieces of the Internet, it, too, is designed and built on the principle of trust... The folks who operate the individual networks that make up the Internet are generally interested in keeping the Internet operating, in keeping the packets flowing. And they do a great job, for the most part. more
The Uptime Institute (UI) is an IT industry research firm best known for certifying that data centers meet industry standards. UI issues an annual report that analyzes the cause of data center outages. The causes for data center outages are relevant to the broadband industry because the same kinds of issues shut down switching hubs and Network Operations Centers. more
In this multipart series I will be presenting some of the leading industry-standard best practices for enterprise network security using Cisco technologies... In Part 1 of this series, I provided an overview of the critical role that properly designed data security architectures play within an Internet-connected organization. Before we begin to discuss the security designs, processes and recommendations related to Cisco technology, let's first discuss some of the ways a network becomes unsecure... more
I attended AWS re:Invent 2016 about three or four weeks ago. Being new to both AWS and to re:Invent I was an outsider again, observing with virgin eyes. This means I learned a lot. Hopefully it means I saw things a bit differently than those more fully entrenched in this new community. So while others have long since covered the product announcements and other major news from the event, I'll take this opportunity to touch on some of the things that struck me as descriptive and/or indicative of the greater trends at play here. more
With the alarming increase in cyberattacks, criminals are literally turning businesses against their own customers in order to steal consumer's personal data, warns the latest annual X-Force Trend and Risk report from IBM. "The security industry puts a lot of effort into the technical evaluation of security threats, examining, sometimes at great length, the potential threat that each issue might present to corporations and consumers. Criminal attackers out for profit, however, have considerations that the security industry does not always take into account, such as monetization cost and overall profitability." more
I don't want to get into the entire Irish Recorded Music Association (IRMA) vs Eircom and IRMA vs ISPs debacle. The only reason I'm even writing this is because I'm getting a bit tired of all the "quotes" of "quotes" and other unclear and misleading things that people have been saying about ISPs over the last few weeks. more
Between December 10th and 11th 2015, the China Future Network Development and Innovation Forum, jointly hosted by the Chinese Academy of Engineering and the Nanjing Municipal Government, is scheduled to be held in Nanjing, Jiangsu, China. The forum will be jointly organized by Jiangsu Future Networks Innovation Institute and Beijing Internet Institute, with the theme of "Building future network test facilities and promoting network development & innovation", and it will invite nearly a hundred industrial experts at home and abroad, to establish a platform marked by security, innovation, openness, cooperation where the policy, industry, academics, and application are integrated. more
The penny dropped when I started looking at cloud computing as a service rather than a new technology. In that respect it is more like Google search and a DotCom development than a set of software and hardware tools. That was what I needed to get a better strategic grip on this new concept. As with all services, business strategies are key here, rather than technologies. As soon as it is seen as a technology customer issues often come in second, which then leads to a technology looking for a market... more
Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) are finally starting to pick up momentum. In the process, it is becoming clear that they are not the silver bullet originally advertised to be. While great for some use cases, emerging technologies like SDN and NFV have been primarily designed for virtual greenfield environments. Yet large service providers continue to run tons of physical network devices that are still managed manually. more
The Department of Energy (DoE) recently came out with an excellent report, called the Magellan report, on the advantages and disadvantages of using commercial clouds versus in house High Performance Computers (HPC) for leading edge scientific research. The DoE probably supports the largest concentration of HPC facilities in the world. I agree with the report that for traditional applications such as computational chemistry, astrophysics, etc. will still need large HPC facilities. more
Global spend on data center hardware and software grew by 17% in 2018 with total infrastructure equipment revenues reaching $150 billion, according to new data released by Synergy Research Group. more
This is a topic that we have discussed on several occasions over the last decade, but it now seems as though things are slowly moving forward. A new company, Intabank, has set up a service whereby its enterprise customers can pool bandwidth that the intermediate company can then use to sell to other customers; enabling organisations to monetise their network connectivity assets. more
Steve Lohr has a nice piece in the New York Times ('Technology Gets a Piece of Stimulus,' 26 Jan 2009, p. C1) this morning about the role that technology and innovation will play in the economic recovery (aka stimulus) bill supported by the Obama Administration. In the past, health IT deployment has been approached as an engineering problem: what computers have to be part of which networks exchanging which types of data? This loses sight of the purpose of electronic medical records... more
