Australia’s national broadband network under relentless attack—by cockatoos

Enlarge / I’m in ur tower, nommin ur Internets (credit: Tim Graham/Getty Images) Australia’s National Broadband Network (NBN) , the effort to bring high-speed Internet to the masses down under, has encountered many speed bumps. The plan to bring fiber-optic broadband Internet to every Australian has been pared back in its ambitions, with a shift to a fiber backbone between “nodes” and distribution over copper wire or cable networks to the majority of users. That cost-saving move, which puts ISPs and cable providers in charge of managing customers’ access,  has caused some consternation . But now the operators of the NBN have discovered another problem that affects the cost of delivering the backbone. And it’s for the birds. The BBC reports that NBN technicians have discovered cockatoos have been damaging the ends of spare fiber cables left in place on communications towers for future network expansion by chomping on them, wearing through the steel braiding that protects the fiber. Active cables haven’t been affected, so there has been no loss of service (as of yet) due to cockatoo attacks; the ends of cables carrying active traffic are protected by a plastic cages. But cables left with their ends exposed have become a favorite of the birds, who use them to help wear down their ever-growing beaks. And the cables cost AUS$10,000 (about US$7,700) to replace. NBN’s Chedryian Bresland told the BBC, “That’s Australia for you. If the spiders and snakes don’t get you, the cockies will.” Read 1 remaining paragraphs | Comments

DARPA tests buoy network for fallback military comms at sea

It doesn’t matter how many war machines you have under your command if you can’t relay orders to their operators. Maintaining communications is just as important as firepower, and DARPA wants the armed forces to have as many contingencies as possible when networks go down or are actively jammed. Setting up a fallback network is even trickier on the open ocean, but the agency’s Tactical Undersea Network Architecture (TUNA) program is well on its way to a solution. That solution being a collection of “node” buoys, deployed from ships or planes, that are tethered together by fiber optic cables to create a radio frequency data network. The fiber cables connecting the buoys may be thin, but are being developed to survive 30 days in challenging underwater environments, which should cover the time it takes to restore normal comms. Powering the network presents another problem, though the University of Washington’s Applied Physics Lab have created a concept buoy that draws energy from the constant ebb and flow of the ocean. The TUNA program has been in DARPA’s pipeline for the past few years , and with the first phase now complete, the next step is to build a fully working system and test it at sea. DARPA’s seafaring solution compliments another ongoing program called Dynamic Network Adaptation for Mission Optimization (DyNAMO) . Its goal is to develop a system that allows all different types of equipment found in different types of aircraft to talk to each other, creating something of a peer-to-peer communications network in the sky.
