NetAdmin challenge: Go to Mars, connect a rover, orbiter and three bases
Tuesday, 18 April 2017 19:02

The Mitre Corporation has given network administrators something to chew on, in the form of a simulator that lets them build networks in space.

Mitre is a not-for-profit organisation that administers some of the United States' Federally Funded Research and Development Centers, public-private partnerships that conduct research for the US government. MITRE’s Technology Transfer Office releases some of the resulting work into the public domain, such as this 1.7GB Ubuntu .ISO that bundles the Common Open Research Emulator with version 3.5.0 of the Interplanetary Overlay Network and the Disruption Tolerant Networking Development Kit

That collection of code offers three challenges:

RIP Bob Taylor: Internet, desktop PC pioneer powers down at 85
Tuesday, 18 April 2017 09:40

Obit Robert Taylor, who oversaw the creation of the internet's precursor ARPANET, the computer mouse and the first GUI-based personal computer, has died after a long illness. He was 85.

For over 50 years, Bob Taylor was at the forefront of research into computing. He had a hand in many of the technologies we take for granted today, and it's his role in the birth of the internet that brought him lasting fame in the industry.

Taylor was born on February 10, 1932, in Dallas, Texas, and was adopted by a traveling Yale-educated reverend and his wife. In his early

Riverbed slurps Xirrus to take SD-WAN all the way to Wi-Fi
Thursday, 20 April 2017 11:32

Riverbed has acquired Xirrus for an undisclosed sum and will now try to build a software-defined WAN that stretches all the way to Wi-Fi access points.

Xirrus makes enterprise-grade Wi-Fi kit that packs multiple access points into a single chassis, then combines their traffic with an in-chassis switch. The many radios inside the company's kit are software-definable and that's driven from a cloud-hosted application. The privately-held company is thought to have had revenue of between $50m and $100m.

Riverbed is to bake Xirrus into its SteelConnect software-defined WAN product, the idea being to build a virtual network that goes from

nbn™ joins standards body CableLabs
Thursday, 20 April 2017 08:02

Yet more evidence, as if we needed it, that nbn™ has little interest in more FTTP nbn™, the organisation building and operating Australia's national broadband network (NBN), has won membership of CableLabs, the global R&D body that develops technologies and standards that help cable operators deploy new services on existing hybrid fibre coax (HFC) networks.

Such networks were often built by cable television operators. CableLabs boffins helped such outfits to deploy broadband services on existing networks. nbn™ found itself in possession of two such networks and while the one built by Optus has turned out not to be fit for

Simple Scanner Finds the Best WiFi Signal
Saturday, 22 April 2017 07:01

Want to know which way to point your WiFi antenna to get the best signal? It’s a guessing game for most of us, but a quick build of a scanning WiFi antenna using mostly off-the-shelf components could point you in the right direction.

With saturation WiFi coverage in most places these days, optimizing your signal might seem like a pointless exercise. And indeed it seems [shawnhymel] built this more for fun than for practical reasons. Still, we can see applications where a scanning Yagi-Uda antenna would come in handy. The build started with a “WiFi divining rod” [shawnhymel] created from …read more

Intel's buggy Puma 6 chipset earns Arris a gigabit-modem lawsuit
Tuesday, 11 April 2017 10:07

Cable modem maker Arris is facing a class-action suit over its handling of a lag-prone line of cable modems.

The complaint , filed in the Northern California District Court, accuses the vendor of violating four California state consumer protection laws and seeks relief for folks in the Golden State who purchased an Arris SURFboard SB6190 modem since its launch in late 2015.

According to the complaint, Arris violated state laws on misleading advertising and unfair competition, as well as consumer protection and warranty laws, when it advertised and sold the SURFboard cable modems as "gigabit" home internet boxes.

As covered
