Carrier Ethernet 2 Aims For Global Connectivity 44
alphadogg provides this extract from Network World: "The Metro Ethernet Forum has updated its Carrier Ethernet specification, hoping to standardize the use of Ethernet for global multicarrier services. 'With Carrier Ethernet 2, we're expanding Quality-of-Service [QoS] well beyond best efforts, and will now allow carriers to interconnect to provide worldwide [Ethernet] service,' said Bob Metcalfe, co-inventor of Ethernet, during a Metro Ethernet Forum Web conference held Thursday to announce the specification. The forum introduced Carrier Ethernet in 2005 as a set of extensions that describe how data communications carriers should use Ethernet in a consistent manner. The new specification, Carrier Ethernet 2, establishes an additional set of rules."

The possibility that I could get something like a 10Mb metro ethernet line to my house for the same price I'm paying for shitass DSL makes me shiver in delight.
Of course, this means that it won't happen until the entrenched telcos figure out a way to oversell it by 50% and charge you like it was a T1 from the mid-90s.

Um.. if they weren't overselling, they wouldn't need QoS or 'best effort'.. the whole point of Ethernet here is it's bursty in nature, so you can actually get a better over-sub rate if you manage your network correctly.

My thinking is pretty much what Wiki cites [wikipedia.org] it as "Overselling or Overbooking refers to the selling of a volatile good or service in excess of actual capacity. Overselling is a common practice in the travel and lodging industry. In telecommunications, sometimes the term oversubscription is preferred."... There may be a more specific usage of the term I'm not familiar with.
SLAs and BE can cover/handle congestion situations (possibly covered by Oversubscribed services being all used at once).. they are more of

You can only absolutely control traffic that you send, so you're only winning half the battle there... You can attempt to *influence* the inbound traffic by doing things like throttling TCP and adjusting windows, but you can't use the same mechanisms on UDP traffic.

It's not possible to have bandwidth in the core equal to or exceeding (in order to guarantee no congestion) bandwidth at the edge - especially if we started talking about FTTH with speeds of 10, 100 or conceivably 1000Mbps at some near point in the future.
Business realities aside, you still have to allow for peer to peer which will consume any available bandwidth if you don't choke it down at the access layer.
I recently built an ISP core in a western European country who is trying to have enough bandwidth i

It isn't about "last mile" edge connectivity, it's about replacing SONET backhaul links with Ethernet, partly because it's cheaper, and partly because Ethernet these days packs a lot more bits onto into relatively cheap copper than a single SONET link manages even on single-mode fiber.
It's also a lot about Bob Metcalfe. You ever watch a show called Royal Pains? There's a character who introduces himself to everyone, no matter how unrelated to a business transacton, with his full name and title, "Evan R. Lawson, CFO of HankMed". The inventor of Ethernet, Bob "I invented Ethernet" Metcalfe, who invented Ethernet is kind of like that. Did I mentioned he invented Ethernet? He will.

Yes and No. There's a world of difference between the world of basic or unmanaged switches you'd find on a LAN, and the world of Carrier-grade MPLS-TE or PBB-TE. The good is if you're a really GOOD small LAN admin, you at least understand the unpinnings concepts of Ethernet switching and hopefully some basic routing.. ...but Elvis help you if you go from a little 3Com switch and a Linksys Router into 'big iron' routing....

I'd personally argue the world would be a better place if everyone didn't know what x-PON was.. but I realize there's alot of legacy infrastructure that needs to be supported and companies are unable/unwilling to goto regular Ethernet (or 'Active Ethernet' if you go by the MEF speak.. which.. is just silly of a title.. i'm not talking 'Active Ethernet PtP' because that's just retarded. put a switch

Don't think anybody said that this connection was available across all of Estonia.
If he lives in Tallinn, or one of the other larger cities, it is as densely or less densely populated as most cities around the planet, so the ability to provide internet there for a given price and at a given service-level should be equal to that of most ofter cities.
Basically, you should at least be able to get the same product for the same price, in London, Washington and other large cities, particular if cost is proportion

I'm currently on the wrong side of town (about a mile away), but my ISP (sonic.net) is offering gigabit fiber with 2 unlimited phone lines for $69.95/month. 100MBit & 1 line is $39.95.
I'm wondering if I should wait for it to get here, or move :-)

Are there any carriers or ISPs that offer WiMax? I'd think that ISPs who wanted to offer wireless internet services w/o becoming mobile carriers might consider this an option. If they could leverage the current WiFi chipsets in most devices, and support IPv6, the standard could successfully escalate as well.
Also, this Carrier Ethernet standard - is it an extension of 802.3, or something else?
