There are 2 appliances Riverbed has announced, adding to the SteelConnect SD-WAN products they launched a couple of years ago. The first new appliance is the SteelHead SD. The second appliance is the SteelConnect SDI. Are these enough to make Riverbed a major SD-WAN player?

In the previous post I’ve demonstrated a special-purpose CNI plugin for network simulations inside kubernetes called meshnet. I’ve shown how relatively easy it is to build a simple 3-node topology spread across multiple kubernetes nodes. However, when it comes to real-life large-scale topology simulations, using meshnet “as is” becomes problematic due to the following reasons:
That is why I built k8s-topo - an orchestrator for network simulations inside kubernetes. It automates a lot of these manual steps and provides a simple and user-friendly interface to create networks of any size and configuration.
k8s-topo is a Python script that creates network topologies inside k8s based on a simple YAML file. It uses syntax similar to docker-topo with a few modifications to account for the specifics of kubernetes environment. For instance, the following file is all what’s required to create and configure a simple 3-node topology:
etcd_port: 32379

- endpoints: ["host-2:eth2:23.23. Continue reading
As data analytics have improved, the massive amounts of data that companies acquire from their customers has only gained in economic value. In the corporate world of today, this data can be a real asset for companies. However, as today’s news, that the records of over 500 million guests of Marriott International’s Starwood division hotels were involved in a data breach, makes clear, corporate thinking about the value of customer data needs to be reevaluated.
Especially when it comes to corporate acquisitions, companies need to start treating customer data as a potential liability, as well as an asset.
In September 2016, Marriott International acquired Starwood for $13.6 billion. When Marriott International sought to buy the Starwood hotel chain, Starwood’s customer data, played a central role in their reasoning for the acquisition. Citing higher income and better brand loyalty among program members, Arne Sorenson, the Marriott CEO, specifically referred to Starwood’s loyalty program as a “central, strategic rationale for the transaction.” Loyalty programs, in addition to attracting repeat customers, also “provide hotels with a wealth of information on their guests” which hotels can use to “create laser focused marketing campaigns for various different kinds of guests.”

SDxCentral Weekly Wrap for Nov. 30, 2018: Nokia creates access networks group, and more.
The company uses AWS SageMaker Ground Truth to create natural language understanding models for customer service conversations.
The elephant in the room on both earnings calls was the VMware-AWS relationship. The latest offering — AWS branded servers running in customers’ on-premises data centers — could hurt legacy hardware vendors like Dell.
To hear the moans on Wall Street, you’d think the end of the world is no longer coming—it has arrived. Successive waves of selling have pushed share prices down this year. To about where they were at the beginning of the year. Hardly a catastrophe for investors. Continue reading
Google Cloud lands in Hong Kong; Infinera adds optical network to its open line system; and plenty of news from AWS re:Invent.
Let’s examine the assertion from Silver Peak that they can replace WAN routers. Is an SD-WAN device able to be a drop-in replacement for a WAN router from Cisco or whomever? Probably, but it depends.

As barriers to entry start to fall, the Internet of Things (IoT) industry could provide Africa with an opportunity to build a brighter economic future.
Several countries are already establishing tech hubs that could supply the infrastructure to fuel IoT, and while there is still a wide gap between the haves and have-nots of Internet access, with more than 60 per cent of Africa still offline, it’s easy to build a case for connectivity.
Mass urbanization is on the rise, and investing in the infrastructure needed to fuel future smart cities and connect more Africans to the opportunity the Internet offers is a logical step forward. But it’s also important that security is in place to support this promising new economy.
Unfortunately, many IoT devices are rushed to market with little thought for basic security and privacy protections. In a world with so many newly connected things, it’s hard for consumers to keep up – and to know if manufactures are protecting their privacy and security.
To address this, Senegal has taken a critical first step. They’ve signed a memorandum of understanding with the Internet Society to strengthen IoT security. Together, they will develop an IoT Security Framework for Senegal Continue reading
I stumbled across a great Reddit thread this week: Is the CCIE as impossible as it seems? There are a lot of great replies on that thread about people passing and the “good old days” of Banyan Vines, Appletalk, and more. It’s also a fascinating look into how the rest of the networking industry sees exams like the CCIE and JNCIE. Because those of us that have the numbers seem to be magicians to some.
Have you ever seen the cups and balls magic trick? Here’s an excellent example of it from the recently departed Ricky Jay:
Impressive, right? It’s amazing to behold a master craftsman at work. Every time I watch that video I’m amazed. I know he’s doing sleight of hand. But I can’t catch it. Now, watch this same video but with annotations turned on. SPOILER ALERT – The annotations will tell you EXACTLY where the tricks are done:
Is it more impressive now that you know how the tricks are done? Check out this demonstration from Penn and Teller that shows you exactly how they do the tricks as well:
