I wonder what Tom Nolle would say in light of this item: Avici Systems Inc. (Nasdaq: AVCI - news), a leading provider of scalable core routing solutions for intelligent IP-over-optical networks, Riverstone Networks, Inc., (Nasdaq: RSTN - news), a leader in service creation infrastructure for metropolitan area networks and CommVerge Solutions Limited, the leading network integrator in the Asia Pacific region, today announced that Chung Hwa Telecom will deploy Avici TSR® scalable core routers and Riverstone RS 8000 metro routers as the foundation for development of high-value services in its next-generation research network. The deployment consists of Avici TSR's supporting up to OC-192c/STM-64 speeds and Riverstone RS 8000's supporting interfaces including Fast Ethernet, T1/E1, POS/SDH STM-1 and ATM STM-1. Chung Hwa Telecom, the largest telecommunications carrier in Taiwan, aggressively drives Taiwan's telecom research and development by leveraging next-generation network technologies to increase operational efficiency and service delivery. Chung Hwa Telecom is focused on delivering enhanced value-added services such as DSL, voice, video, and VPNs to the Taiwanese market. Avici's leading carrier-class core routing platform provides the scalability and reliability required to consolidate costly overlay networks, and deliver new differentiated services to customers. Riverstone Networks is a leading supplier of routers that convert raw bandwidth into profitable services for metropolitan area networks, enabling carriers to deliver new services, including on-demand bandwidth provisioning and virtual private network applications for home and office connectivity. Something like, "it isn't GigE" or "it isn't PON"?

The street cuts that are done to create rings in metro settings can be leveraged to satisfy numerous customers along the circumferences of those rigns (and physical ring circumferences in metros usually interlock with one another on at least one side, leaving mutlipe paths of egress for any user), whose locations adjace them. In order to create a physical mesh in the metro that is unuiquely tailored for each individual end users end points, discreet street cuts have to be made for every location, or discreet locations need to backhaul their traffic - in a Pyrrhic victory sense - to metro fiber pops in an awkward and costly manner. It's the railroad station syndrome that we're dealing with here. People take their cars or car pool to the train station. Railroads don't lay track to every passenger's home. Rings have self-healing technologies. They restore themselves within so many miliseconds (typically 50 ms terrestrially). Meshes usually take much longer to converge if they are entirely dependent on IP for doing so, which results in lost sessions and SLA penalties, because they time out <read: the session is lost> before convergence <read: recovery> takes place. To satisfy your assertion and implied questions concerning recovery... in the railroad analogy, the railroad would have to lay track to every passenger's home, and then have a second route to get there in case there is a blockage along the first route. In order to achieve this, we're talking street cuts. To achieve the same thing in the WAN (using, say, an Avici <or anyone else's, for that matter> router> we're only talking about leveraging long haul carriers existing routes. The grief is amortized across greater distances and a far greater number of users. Which, in turn, translates to the capability of satisfying the diversity needs of many, as opposed to those of just one or two users at a higher unit cost per. Let me know how you make out with Duffy. Tell him I said hello. In case you didn't notice, I left his forwarding information at the bottom of the post for this very reason: From the bottom of my original post, "... to contact Jim Duffy... he can be reached at jduffy@nww.com " I can't answer on his behalf for all of his asertions, although I think he's right on most of them.
