When is that book of yours coming out? -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of sgorman1@gmu.edu Sent: Monday, August 08, 2005 1:34 PM To: Gordon Cook Cc: nanog@merit.edu Subject: Re: Of Fiber Cuts and RBOC Mega-mergers The unfortunate part of all this is there is a demand for diversity, especially from the financial and government sectors. One of the big problems is that clients seldom know which providers or combinaiton of providers give them the most diversity. There are some intersting ways to claculate the optimal set of providers by price and diversity, but getting the data is quite difficult. Sometime large clients like the US government can leverage providers into divulging routing and right of ways, but is definately the exception. Even from our rough analyses there are several areas of heavily shared colocation. Sounds like the problem is getting worse and not better. ----- Original Message ----- From: Gordon Cook <cook@cookreport.com> Date: Monday, August 8, 2005 4:17 pm Subject: Re: Of Fiber Cuts and RBOC Mega-mergers
So although we have the technology to build networks controlled at
the edge and networks that are less subject to failure, the old business models that we cant seem to break out of insist that we remonopolize walled garden telephone monopolies. Why? Because we imagine them to have wondrous new capabilities of
economy of scale. We concentrate the fiber and the switching centers into evermore centralized potential points of failure. We rob ourselves of redundancy. As with the cisco router monoculture in our backbones which god help us if it ever failed, we are now building a potential concentration of fiber. Higher and potentially more fragile than the twin towers. How sad.
How can we gain some understanding of other ways to look at infrastructure? This is terribly short sighted.
How many enterprises do you see Frank that may begin to understand
they better build their own infrastructure. because perhaps placing all your infrastructures marbles in the equivalent of a new set of twin towers is not a good execution of your fiduciary responsibility to your shareholder...never mind the public at large?

All,
Tracking the preceding discussion on fiber cuts has been especially interesting for me, with my focus being on the future
the pending RBOC mega-mergers now being finalized. The threat that I see resulting from the dual marriages of SBC/AT&T and VZ/MCI will be to drastically reduce the number of options that network
both enterprises and xSPs have at their disposal at this time for redundancy and diversity in the last mile access and metro transport layers. And higher than those, too, when integrations are completed.
These mergers will result in the integration and optimization of routes and the closings of certain hubs and central offices in order to allow for the obligatory "synergies" and resulting savings to kick in. In the process of these efficiencies unfolding, I predict that business continuation planning and capacity planning processes, not to mention> service ordering and engineering, will be disrupted to a fare-thee- well, where end users are concerned.

While it's true that an enterprise or ISP cannot pin point where

places, it is at least possible to fairly accurately distinguish routes from disparate providers who are using different rights of way.

Not only will end users/secondary providers lose out on the number of physical route options that they have at their disposal, but once integration is completed users will find themselves riding over systems that are also managed and groomed in the upstream by a common set of NMS constructs, further reducing the level of robustness on yet higher levels in the stack.

Eight or nine people I had talked to thought they had geographically distinct ring loops that turned out to be on that one cable when the second cut took it down hard.
Perhaps now people will begin to take physical separacy seriously and write grooming protocols and SLAs into their contracts?
Or was this type of service "good enough"?
