Rough Guide to IETF 100 – IPv6

In this post for the Internet Society Rough Guide to IETF 100, I’m reviewing what’ll be happening at IETF 100 in Singapore next week.

IPv6 global adoption rates passed 20% shortly after IETF 99, with a number of countries making substantial strides in IPv6 deployment in the past few months. Belgium still leads the way at over 60%, but India has shot up to over 50% which is extremely encouraging in such a large market. Adoption rates also exceed 40% in the United States and Germany, and with most major content and cloud providers now supporting IPv6, there’s a substantial amount of IPv6-related work happening in Singapore. In fact, there’s no less than five IPv6-related working groups on the first day alone.

The IPv6 Operations (v6ops) Working Group is always one of the key groups, and since the last meeting has published two RFCs on Host Address Availability Recommendations (https://tools.ietf.org/html/rfc7934) and Local-Use IPv4/IPv6 Translation Prefix (https://tools.ietf.org/html/rfc8215). The meeting kicks off on Monday afternoon and continues on Thursday morning, starting with a case study on IPv6-only deployment at Cisco.

There are also seven drafts being discussed including 464XLAT Deployment Guidelines for Operator Continue reading

BrandPost: FlexWare: Year Two

It’s been over a year since AT&T introduced its FlexWare offering. It was positioned as the next big thing in enterprise networking, and in the intervening months, AT&T has rolled out a number of important virtual network functions (VNFs) that run on its x86-based FlexWare devices.Those VNFs essentially replace proprietary boxes that historically have been costly to operate and replace in terms of time and money.Light Reading’s Carol Wilson said that AT&T’s venture into “white box services” is “a clear signal to traditional telecom suppliers that the gig’s up on closed system sales.” That’s cheery news to enterprises that have long chafed over the relative inflexibility of on-site equipment solutions.To read this article in full or to leave a comment, please click here

Top 5 From The Last 3 Months

 

In the year 2017, news comes at you fast. So, it’s easy to miss the important or informational items that just weren’t on your radar when they first arrived. While we believe VMware NSX should be firmly on everyone’s virtualization radar, we understand that you may miss a few items from time to time. That’s why we’re putting together this VMware NSX news round-up.

This news round-up recaps the latest NSX-related material you may have missed over the past few months for you peruse at your leisure. We’ll compile these posts again from time to time, so be sure to keep your eye on this space for more VMware NSX news rounds-ups and informational posts!

Real World Use Cases for NSX and Pivotal Cloud Foundry

From the post: Pivotal Cloud Foundry (PCF) is the leading PaaS solution for enterprise customers today, providing a fast way to convert their ideas from conception to production. This is achieved by providing a platform to run their code in any cloud and any language taking care of all the infrastructure “stuff” for them.

From building the container image, compiling it with the required runtime, deploying it in a highly available mode and connecting Continue reading

The Internet, Homemade

The following post originally appeared on the APNIC blog.

The Internet can enhance social inclusion and participation and can contribute to economic development. Therefore, it should be a commodity for every citizen, but, as RFC3271 says, ‘it will only be such if we make it so.’

Internet infrastructure and services do not even reach 50% of the global population. The three main issues affecting Internet growth are: not everyone wants or needs it, not everyone has access to it, and not everyone can provide it.

I respect people’s choices with the first issue since the Internet is not a natural thing that we need to sustain or protect ourselves. However, for many, they don’t want or need the Internet because there is a lack of locally relevant content and services or training on how to use it. Metaphorically speaking: Shall I eat the same fast food made far away when I like my local tasty food not offered here?

Without content and services adapted to my local taste and language, it may not be attractive or digestible. At the same time, local access and education are necessary primers to produce such relevant and meaningful content.

The second and third Continue reading

Widespread impact caused by Level 3 BGP route leak

For a little more than 90 minutes yesterday, internet service for millions of users in the U.S. and around the world slowed to a crawl.  Was this widespread service degradation caused by the latest botnet threat?  Not this time.  The cause was yet another BGP routing leak — a router misconfiguration directing internet traffic from its intended path to somewhere else.

While not a day goes by without a routing leak or misconfiguration of some sort on the internet, it is an entirely different matter when the error is committed by the largest telecommunications network in the world.

In this blog post, I’ll describe what happened in this routing leak and some of the impacts.  Unfortunately, there is no silver bullet to completely remove the possibility of these occurring in the future.  As long as we have humans configuring routers, mistakes will take place.

What happened?

At 17:47:05 UTC yesterday (6 November 2017), Level 3 (AS3356) began globally announcing thousands of BGP routes that had Continue reading

IDG Contributor Network: Why speeds and feeds don’t fix your data management problems

For a very long time, IT professionals have made storage investments based on a few key metrics – how fast data can be written to a storage media, and how fast it can be read back when an application needs that information, and of course, the reliability and cost of that system. The critical importance of storage performance led us all to fixate on latency and how to minimize it through intelligent architectures and new technologies.Given the popularity of flash memory in storage, the significance of latency is not about to fade away, but a number of other metrics are rapidly rising in importance to IT teams. Yes, cost has always been a factor in choosing a storage investment, but with Cloud and object storage gaining popularity, the price of storage per GB is more than a function of speed and capacity, but also the opportunity cost of having to power and manage that resource.  When evaluating whether to archive data on premises, or to send it offsite, IT professionals are now looking at a much wider definition of overall cost.To read this article in full or to leave a comment, please click here

Riverbed enhances its SD-WAN performance monitoring platform

Digital transformation is on every IT and business leader’s radar today. The path to it, though, may not be simple. While many industry pundits like to call out the likes of Uber and AirBnb, those digital natives didn’t have to worry about disrupting an existing business.To help mainstream businesses make that jump to a digital organization, Riverbed launched two new solutions at its Disrupt customer event last week in New York City.Enhanced network performance management The first is a new version of its network and application performance management platform, SteelCentral, enabling IT staff to better understand digital experiences. This aligns with a new movement among the NPM/APM vendors to shift to digital experience management (DEM), providing visibility into customer or worker experience regardless of whether the infrastructure is on premises, in the public cloud or in a hybrid environment.To read this article in full or to leave a comment, please click here

Amazon and Google make it easier to connect to the cloud

As more organizations look to enable hybrid cloud computing, a big question remains: How do I connect my network to the cloud? This week Google Cloud Platform and Amazon Web Services each released new products that make that process easier.Google’s Dedicated Interconnect is now generally available Dedicated Interconnect is an important way for customers to connect to the public cloud. It allows organizations to connect their on-premises resources to a colocation facility and then that co-lo facility has a direct network connection to the public cloud. Public IaaS cloud providers like Google want to give their customers access to fast connections to their cloud, but they don’t want to connect to each individual customer’s site, so they’ve created this co-lo based Interconnect. Google runs the Interconnect and offers either a 99.9 or 99.99% service level agreement. Google is working with a handful of colocation vendors as the middle-man, including Equinix, Digital Realty and Infomart.To read this article in full or to leave a comment, please click here
