This can be a valid solution. Our company has some multimedia traffic that can be axed if a catastrophe befalls our tubes. Obviously we'd prefer not to drop (or ax, as it were) any type of traffic, but it's a monetary decision.

If not, then they are just plain stupid. Is paying for "protected circuits" actually worth it. Or are you better off just buying two circuits and using both during normal conditions. Use switching at layer 3 to the remaining circuit during abnormal conditions. Most of the time, you get twice the capacity for only twice the price instead of a "protected circuit" where you only get the once the capacity for twice the price. Of course, there is still the problem some facility provider will "groom" both your circuits on to the same cable. If you are buying pre-emptable circuits, hopefully you understand what that means.

To clarify my last post, and to partly correct it, I was referring to VZ's new TPE China cable, where I mentioned pending pricing and T&C information. Of course, VZ already meshes its IP backbones, as a matter of course today, in existing systems. Frank A.

Interestingly, some major transoceanic undertakings have begun looking very favorably towards a meshed topology solution, eschewing rings. Verizon is championing this approach at the present time as a consortium partner in the Trans-Pacific Express (TPE) cable laying venture to China, and offers justifications for doing so in several interviews and PPT prezos I've come across. Makes sense. From: http://preview.tinyurl.com/yqcrzm Article "Verizon Business plots business plan for ’07 and beyond" May 2007 Issue of Lightwave Magazine <snip> "Last year, Verizon also took steps to improve the reliability of the transatlantic portion of its global IP network. In the past, traffic moved across the Atlantic over SONET rings, which provided redundant paths. However, such architecture only protects against a single failure in a given ring.

Today, Verizon Business operates a mesh network, using Ciena CoreDirectors (www.ciena.com) to move traffic between six diverse paths that can be routed onto other undersea networks in the event of a network failure." <snip> Of course, these offerings are still being "productized," so it remains to be seen what terms and conditions they carry, and how they will be priced.

One backhoe hit took out the first half of the cable, but the digger realized he goofed and stopped. The fiber company then cut the rest of the bundle to cleanly fix the cut... without warning anyone who was running on their failover protected circuit that something might be about to happen. Major collaboration vendor outage root-caused to that one... -george william herbert gherbert(a)retro.com

AT&T $10 DSL plan
by William Allen Simpson 22 Jun '07

22 Jun '07

Apparently, this has been in the news for a couple of days, but only just hit my hometown paper.... === AT&T Inc. has started offering a broadband Internet service for $10 a month, cheaper than any advertised plan. The DSL, or digital subscriber line, plan introduced Saturday is part of the concessions made by AT&T to the Federal Communications Commission to get its $86 billion acquisition of BellSouth Corp. approved last December. The $10 offer is available to customers in the 22-state AT&T service region, which includes Michigan, who have never had AT&T or BellSouth broadband. === Basically, it's only available to *OUR* customers that switch! What the heck is the FCC thinking? Did AT&T basically say, "Please don't throw me into that briar patch." I cannot even lease dialup lines from AT&T/BS at that rate. It will put all competitors out of business. Anybody considering a lawsuit to stop this happening?

MEDIA: Ruptured Cable Disrupts Internet Service in 5 Latin American Nations

http://biz.yahoo.com/ap/070621/colombia_internet_disrupted.html?.v=1 --- AP - Internet Fails in 5 Latin Countries - Thursday June 21, 6:31 pm ET Ruptured Cable Disrupts Internet Service in 5 Latin American Nations BOGOTA, Colombia (AP) -- Accidental damage to an undersea fiber-optics cable left millions of people without Internet service in five Latin American countries, the cable's owner said Thursday. In Colombia, as many as 45 percent of Internet users were left with limited or no connection. Problems were also reported in Panama, Venezuela, Costa Rica and Nicaragua. In a statement, Columbus said repair ships set sail from Mexico and the company hoped the cable would be fixed on Friday. The statement did not say what damaged the underwater cable. The company said it would investigate the cause. The general secretary of the Colombian phone company, Empresa Telefonica de Bogota, Andres Perez, told The Associated Press that nearly half of this South American country's 5 million Internet users were left without service. The Nicaraguan Internet service-provider Cablenet said a backup system kicked in after the cable's rupture delivering limited but slower service. Costa Rica's state-run Instituto Costarricense de Electricidad also reported a slowing down of Internet service. It is the second problem to befall the Arcos network this month. On June 5, a cable off the coast of Venezuela was cut causing no interruption to service.
