Remembering Pål Spilling

It is with a heavy heart that I report to Internauts everywhere that one of the early pioneers of the ARPANET and Internet has passed away. Pål Spilling was at the Norwegian Defense Research Establishment (NDRE) at a time when an ARPANET node was installed at Kjeller, Norway. The satellite link was shared between the ARPANET and the Norwegian Seismic Array (NORSAR) system that was used to monitor Soviet underground nuclear testing to assure the tests did not exceed the test ban treaty limits. Together with his colleague, Yngvar Lundh, Pål worked to test early Internet implementation and applications including packetized speech. He was ever an enthusiastic participant in the Internet’s evolution and a steadfast research partner at NDRE and the subsequent institutions who were lucky to have him in their midst. He spent time at University College London with Peter Kirstein’s group and also at SRI International testing packet radio and packet speech applications. More about Pål’s work can be found at his Wikipedia site.

I, for one, will miss Pål greatly but remember his workmanlike involvement over many decades. His name can be found on the Stanford Plaque commemorating the early researchers who participated in the earliest development Continue reading

What is fog computing? Connecting the cloud to things

Fog computing is the concept of a network fabric that stretches from the outer edges of where data is created to where it will eventually be stored, whether that's in the cloud or in a customer’s data center.Fog is another layer of a distributed network environment and is closely associated with cloud computing and the internet of things (IoT). Public infrastructure as a service (IaaS) cloud vendors can be thought of as a high-level, global endpoint for data; the edge of the network is where data from IoT devices is created.Fog computing is the idea of a distributed network that connects these two environments. “Fog provides the missing link for what data needs to be pushed to the cloud, and what can be analyzed locally, at the edge,” explains Mung Chiang, dean of Purdue University’s College of Engineering and one of the nation’s top researchers on fog and edge computing.To read this article in full, please click here

CEO Succession at the Internet Society – Status update

A few weeks ago we informed the community about the fact that Kathy Brown was not going to seek another extension of her contract and, thus, a CEO search process had started at the Internet Society (ISOC). Please read my previous blog post for background.

In particular, we had asked the community to send us preliminary input, which is treated as confidential within the ISOC board, to the following email address:

[email protected]

We want to thank the community for all the useful input we have received so far. Please, continue sending us your thoughts around this important process for ISOC.

The status of the process at this point is the following. The board has set up a search committee, which is a subset of the board. The role of the search committee is to do a preliminary review of the candidates (in coordination with the selected search firm) and eventually present a short list to the full board, which will be responsible for the final selection.

The search committee is currently finishing the selection of a search firm to support us during the whole process. We have developed a draft job description, which will be finalized once a Continue reading

History Of Networking – Paul Mockapetris – Origins of DNS

Paul Mockapetris, co-inventor of the Domain Name System, joins Network Collective to talk about how DNS grew from an undesirable computer science experiment to one of the critical services that makes the Internet what it is today.

Introducing Cloudflare Access: Like BeyondCorp, But You Don’t Have To Be A Google Employee To Use It

Introducing Cloudflare Access: Like BeyondCorp, But You Don’t Have To Be A Google Employee To Use It

Tell me if this sounds familiar: any connection from inside the corporate network is trusted and any connection from the outside is not. This is the security strategy used by most enterprises today. The problem is that once the firewall, or gateway, or VPN server creating this perimeter is breached, the attacker gets immediate, easy and trusted access to everything.

There’s a second problem with the traditional security perimeter model. It either requires employees to be on the corporate network (i.e. physically in the office) or using a VPN, which slows down work because every page load makes extra round trips to the VPN server. After all this hassle, users on the VPN are still highly susceptible to phishing, man-in-the-middle and SQL injection attacks.

A few years ago, Google pioneered a solution for their own employees called BeyondCorp. Instead of keeping their internal applications on the intranet, they made them accessible on the internet. There became no concept of in or outside the network. The network wasn’t some fortified citadel, everything was on the internet, and no connections were trusted. Everyone had to prove they are who they say they are.

Server vendors push flex pricing to challenge cloud providers

For some time now, server unit sales have been steadily dropping for the major x86 server vendors as enterprises draw down their on-premises hardware in favor of cloud services.The response from the hardware vendors is if you can’t beat ‘em, clone ‘em. Vendors are adopting a pay-as-you-go model not unlike that of a cloud provider, where you pay for how much compute time you use and hand back the hardware when you are done rather than buying it outright.+Check out our review of rack servers from  HP, Dell and IBM and tips on calculating the true cost of cloud migration+To read this article in full, please click here
