|We must fight spam for the same reason we fight crime: not because we are naive enough to believe that we will ever stamp it out, but because we do not want the kind of world that results when no one stands against crime. - Geoffrey Welsh|

At a previous job, I had a gigabit connection to the internet at my desk. (So did everyone else. There were several 10 gig connections shared among a couple hundred people.) I was routinely able to use 80% or more of capacity doing things like downloading software installation dvd images. That was seven or eight years ago. I have no doubt that many other bandwidth hogging uses would occur to me these days. Also, remember, that most of these links will be shared by more than one user. -- sig 121|

Of course nothing singularly out on the Internet can fill a 10G pipe. (NB: I am in a good position for you, since I run a small regional service provider network, we have dual 10G Internet feeds currently. I'm also on the tech community of our regional Internet Exchange, where I can see the multitudes of users push data way beyond that). Nothing singularly out there can even fill a 1Gbps pipe. You definitely start running into server limits at that speed. Ie. a fast singular hard drive now-a-days can feed data back into a server at around 130MB/s, - just over 1Gbps. (athough enterprise Hybrid RAID and especially SSD drives can go much faster than that). I'd say that my typical download from a real fast server could maybe get upwards of 450-500Mbps peak. But those are pretty rare and infrequent. More typical "fast" servers could be in the 120Mbps range. Slower servers would push you down into the range of the average mid-to-higher-end cable users. Of course, I've been careful to say "singularly" frequently. Where we need the bandwidth, is where many many users download a lot of data. Say from Netflix or Youtube. When you have unknown thousands or 100's of thousands of users, all trying to get Netflix at once, that becomes quite the traffic fire hose of data. -- Doug McIntyre email@example.com|

Subject: FCC, Canada agree on spectrum plan ahead of auction Message-ID: <firstname.lastname@example.org> By Andrew Berg, CED, 8/17/2015 The FCC is continuing its efforts to harmonize TV and wireless spectrum bands with Canada as part of preparations for the upcoming incentive auctions. In a blog post on the Commission's website, Gary Epstein, Incentive Auction Task Force Chair, and Mindel DelaTorre, International Bureau Chief, wrote that the FCC and Industry Canada have finalized a Statement of Intent (SOI) that sets forth a framework and timeline for the repurposing TV spectrum for mobile broadband on both sides of the border. http://www.cedmagazine.com/news/2015/08/fcc-canada-agree-on-spectrum-plan-ahead-of-auction?et_cid=4747839&et_rid=652835436&location=top -or- http://tinyurl.com/ng2ummu Neal McLain ***** Moderator's Note ***** Were I in change of the RF spectrum in Canada, I would be demanding a minimum one-billion-dollar fee per auction, just to save the bidders from having to do it twice.
