How NSX Is Tapping into the Human Element Behind Network Virtualization

How NSX Is Tapping into the Human Element Behind Network Virtualization Virtualization can be a tricky concept for some people to wrap their heads around. Trying to explain the functionalities and benefits of technology like VMware NSX can quickly devolve into techno-babble. With that said, we’re trying to take another approach—a more human approach. Below are three customer stories that emphasize a human-interest element behind network... Read more →

Shedding light on broadband performance for an optimized SD-WAN

A decade ago, if I had asked a network manager to consider using broadband to connect branch offices, he would have looked at me as if I had a second head. Times and opinions change, though, and broadband is now as viable as MPLS or any other network service.The catalyst for this has been the rise of software-defined WANs (SD-WANs). Their multipath capabilities and network optimization make it possible to use broadband for business connectivity, and organizations of all sizes have been jumping aboard this trend. One of the challenges that remain, though, is that not all connections or types of broadband are created equal.Not all broadband is created equal A network manager at a business with branches located nationwide recently told me that his company's preferred broadband type has been cable, but he has been surprised by the variability in the resulting bandwidth by location and time of day. For example, in one large metro area, he is purchasing 50MB of bandwidth, more than adequate for most branches. During the mornings he often sees throughput of 100MB or more. Later in the day, however, when kids get home from school and the Xboxes and Netflix subscriptions start Continue reading

Show 382: Whitebox In The Enterprise With Pica8 (Sponsored)

On today’s show we explore whitebox switching in the enterprise with our sponsor Pica8.

Pica8 makes a network OS for data centers and enterprises, which customers can run on a variety of third-party switches including Dell, HPE, and Edgecore.

Our guests are  James Liao, CEO and co-founder of Pica8; and Sharad Ahlawat, VP of Technology.

We get details about Pica8’s switch OS, called PicOS, and find out how Pica8 differentiates itself from other OSs.

We also talk about how SDN has to change to be useful, such as targeting specific use cases. We look at the state of the whitebox market, the role of open source, and why Pica8 is shifting its focus to enterprise customers.

ExtremeAnalytics provides granular insights into how the network performed throughout the event, as well as providing a detailed understanding of the mobile engagement behaviors of connected fans.To read this article in full, please click here

BrandPost: An Efficient Network: The Fabric of a Complex Paperless Hospital System

As CTO of a large regional hospital system, I know that the network is vital to everything. I consider the network in the same critical category as electricity, oxygen, and water. It needs to be available 24x7x365 to support Concord Hospital’s half a million patients and over 5,000 network users across our 30 locations.Because we don’t do anything on paper, the network can never go down. Extreme Fabric Connect has solved that problem for us. It provides a secure, self-healing, highly-available network to serve our patients effectively in our complex paperless environment. All the Benefits of MPLS, None of the HeadachesWe decided to upgrade our network from Split Multi-Link Trunking to Fabric Connect to get the self-networking benefits of Multiprotocol Label Switching (MPLS) without the complexity. Fabric Connect is like having a carrier-class MPLS network, where you can put any network anywhere and only the right people can see it.To read this article in full, please click here

Introducing Certificate Transparency and Nimbus

Introducing Certificate Transparency and Nimbus

Introducing Certificate Transparency and Nimbus

Certificate Transparency (CT) is an ambitious project to help improve security online by bringing accountability to the system that protects HTTPS. Cloudflare is announcing support for this project by introducing two new public-good services:

  • Nimbus: A free and open certificate transparency log
  • Merkle Town: A dashboard for exploring the certificate transparency ecosystem

In this blog post we’ll explain what Certificate Transparency is and how it will become a critical tool for ensuring user safety online. It’s important for website operators and certificate authorities to learn about CT as soon as possible, because participating in CT becomes mandatory in Chrome for all certificates issued after April 2018. We’ll also explain how Nimbus works and how CT uses a structure called a Merkle tree to scale to the point of supporting all trusted certificates on the Internet. For more about Merkle Town, read the [follow up post] by my colleague Patrick Donahue.

Trust and Accountability

Everything we do online requires a baseline level of trust. When you use a browser to visit your bank’s website or your favorite social media site, you expect that the server on the other side of the connection is operated by the organization indicated in Continue reading

Is Patching And Tech Support Bad? A Response

Hopefully, you’ve had a chance to watch this 7 minute video from Greg Ferro about why better patching systems can lead to insecure software. If you haven’t, you should:

Greg is right that moral hazard is introduced because, by definition, the party providing the software is “insured” against the risks of the party using the software. But, I also have a couple of issues with some of the things he said about tech support.

Are You Ready For The Enterprise

I’ve been working with some Ubiquiti access points recently. So far, I really enjoy them and I’m interested to see where their product is going. After doing some research, the most common issue with them seems to be their tech support offerings. A couple of Reddit users even posted in a thread that the lack of true enterprise tech support is the key that is keeping Ubiquiti from reaching real enterprise status.

Think about all the products that you’ve used over the last couple of years that offered some other kind of support aside from phone or rapid response. Maybe it was a chat window on the site. Maybe it was an asynchronous email system. Hell, if you’ve ever installed Continue reading

IDG Contributor Network: Stay smart as you approach the edge

Fundamental to harnessing the full potential of the Internet of Things (IoT) is the need for decisions to be made in real time, and it’s in addressing this that discussions have turned to the subject of edge computing over recent years.Before the data generated by myriad of connected IoT devices is sent to the centralized cloud, edge computing sees it stored and processed locally, in distributed micro-clouds at the edge of the network, closer to where the devices are placed, and the data produced. Doing so cuts down on the need for data traffic to be back-hauled to and from a remote data center, thus making it ideal for supporting the real time data delivery required by the IoT.To read this article in full, please click here
