Submission + - Ethernet Zooms to 100 Gigabit Speeds

Doc Ruby writes: As reported at GigaOM, 'Infinera has bonded 10 parallel 10 Gb/s channels into one logical flow while maintaining packet ordering at the receiver', bridging 100Gbps ethernet over 10 10Gbps optical WAN links:
Infinera, a San Jose, Calif.-based start-up, along with University of California, Santa Cruz, Internet2 and Level3 Communications, today demonstrated a 100 gigabit/second Ethernet connection that could carry data over a 4000 kilometer fiber network. The trial took place at the Super Computing Show in Tampa, Florida. The experimental system was set up between Tampa, Florida and Houston, Texas, and back again. A 100 GbE signal was spliced into ten 10 Gb/s streams using an Infinera-proposed specification for 100GbE across multiple links. The splicing of the signal is based on a packet-reordering algorithm developed at the University of California at Santa Cruz. This algorithm preserves packet order even as individual flows are striped across multiple wavelengths. [...] [A]bout 14 months ago we wrote about the 10 GB/s network4 that connected the University of California, San Diego and NASA Goddard Space Flight Center over a dedicated optical path. [...] [Infinera co-founder and CTO Drew Perkins] said that the trial today shows that you can build scalable systems that can achieve higher speeds.
With most data we prosume now large multimedia objects/streams, mostly networked, we're all going to want our share of these 100Gbps networks. The current network retailers, mainly cable and DSL dealers, still haven't brought even 10Mbps to most homes, though they're now bringing Fiber to the Premises to some rich/lucky customers. Are they laying fiber that will bring them to Tbps, or will that stuff clog the way to getting these speeds ourselves?

The Moon's Magnetic Umbrellas 125

eldavojohn writes "When it comes to space exploration, there are things that are good for humans (water) and things that are bad for humans (radiation). In order for exploration of the moon to occur, its lack of a global magnetic shield to block solar radiation must be addressed. Luckily, scientists have discovered that there are highly magnetized areas of the moon's crust that could shield settlements." From the article: "Current evidence suggests that impact-basin ejecta materials [material blasted out by huge asteroid or comet impacts] are the most likely sources of many or all of the magnetic fields ... These ejecta contain microscopic metallic iron particles that are the carriers of the magnetization."
