Then there's this little baby: Riverstone Networks Demonstrates Lead in Hardware-Based Metro MPLS Implementation Demonstration Shows Core Router Interoperability, Broad Range of Hardware-Based MPLS Features SANTA CLARA, Calif.--(BUSINESS WIRE)--May 16, 2001-- Riverstone Networks, Inc., (Nasdaq:RSTN - news) a leader in service creation infrastructure for metropolitan area networks, established its early leadership in the hardware implementation of metro Multi-Protocol Label Switching (MPLS) features and demonstrated core router MPLS interoperability at the InteropNet Labs (iLABs) in Las Vegas. At the demonstration, Riverstone presented hardware versions of several Layer-2 tunneling technologies and again established core router MPLS signaling interoperability. These capabilities are critical to the metro MPLS-VPN model and will help service providers use Riverstone's products to design and sell virtual leased line and transparent LAN services in the metro. ``The MPLS capabilities that Riverstone exhibited at iLABs were extremely impressive,'' said Bill Jensen, senior network engineer at the University of Wisconsin and lead architect of the iLABS MPLS testing. ``Riverstone successfully displayed hardware-based Layer-2 tunneling technologies in a multivendor environment, and thereby made a substantial contribution to the interoperability demonstration.'' The iLABS at N+I is an important and recognized forum for demonstrating interoperability between network equipment. At the show, Riverstone's RS metro routers ran MPLS over a new line of programmable MPLS-Gigabit Ethernet interfaces, and successfully completed three classes of interoperability demonstration: RSVP-TE. Riverstone showed LSP creation with Juniper and Cisco core routers and other edge routers, using, inter alia, explicit route object, loose and strict modes, CSPF and no-CSPF, admin-group, and bandwidth reservation. This demonstration included the successful setup and tear down of 1,000 LSPs with the Sprient/Adtech MPLS tester, along with the creation of an end-to-end Layer-3 RSVP LSP with a Juniper core router, to demonstrate wire-speed label switching. LDP over LDP Martini-Draft Layer-2 Tunneling. This demonstrated full LDP interoperability with core routers, and included the creation of a LDP over LDP layer-2 tunnel through a Juniper core router, and passing bi-directional traffic generated by an IXIA tester. OSPF-TE. Riverstone demonstrated OSPF-TE interoperability with Juniper and Cisco core routers. ``We are very pleased to learn that our MPLS development effort is paying off in terms of technological leadership,'' said Romulus Pereira, president and CEO of Riverstone Networks. ``We appreciate iLABs' contribution to the promotion of interoperability, which is particularly important given the evolving nature of MPLS standards. I reiterate that MPLS and tunneling technologies remain central to our vision of metro area service creation.'' Can you believe that, ye mast headers?

I wouldn't link those two points quite the same way. "Frank Coluccio always thought VDSL had a shot..." Well, not "always," but before the industry showed definite signs that they would not commit and take the step to deploy in any meaningful numbers - which had the resulting effect of NOT driving costs down due to the lack of mass production - yes.. I thought that they had a shot at one time. In particular, Next Level's wares, before they were taken out by GI. And VDSL may have another shot soon, with the removal of the ATM layer and replacing it with Ethernet as a means of all-round simplification and streamlining, hence driving its overall cost of ownership to the carriers down substantially, as in Ethernet over VDSL, or EoVDSL. Reportedly, they would retain the Layer 1 silicon functions of native vdsl and make the Layer 2 substitution from ATM to Ethernet. This is just one of the outside plant twisted pair proposals being considered in the Ethernet in the First Mile Forum at this time. Whether it goes anywhere or not remains to be seen. But in the following I have to correct you: "...and that [vdsl?] was part of the reason why he had his doubts about ATHM." "Doubts" is the wrong word, but I made numerous observations concerning a broad range of other issues, not the least of which was architectural in nature... but there were other over-riding aspects of what home was going through at the time. Briefly, these had to do with: - the Cartel who owned them; - what T would eventually do with them; - conflicts of interest wrt cable ops offering competing services with them, especially set top box-based multimedia versus a pipe-constrained attempt for home to do it themselves over DOCSIS; - their preparedness or lack thereof to deal with open access, which could have turned out to be a money maker, I'm still convinced, if they had embraced it proactively, despite the engineering challenges that they would have had to overcome; - the fact that their hands are, and always were, tied, preventing them from acting on their own behalf in attempting to deal with issues such as the one just covered (open access); - the mergers and acquisitions they made with and of foo-foo content providers that cost at least a thousand times more than they were worth, if they were worth anything, at all; - I can go on. You do recall those issues, don't you? Those are the ones that we took a heap of flack over at the time. Oddly enough, though, they are the very same issues that are now being discussed in retrospectives, as though no one ever brought them up before. Those issues. But my thoughts concerning Home were not influenced by any notions that VDSL was superior to HFC, per se, although, if properly implemented it could be, depending on the shape of the HFC. I'm pretty sure, however, that by the time frame you are referring to I had already gravitated to a preference for FTTH, whose cost structure was first beginning to come down. Yeah, yeah.. it's still expensive, but not hardly as much as it was. In fairness, if HFC receives the proper level of attention and eventual upgrade and triage - I include 'triage' because triage is endemic in many extant HFC systmes due to the level of ingress experienced by coaxial connectors and other outside fixtures that support transmission at *Radio Frequencies* - then HFC itself wouldn't be much of a concern, either. But going back into the plant, for a third time, to do yet another upgrade is going to be very expensive, especially if the approach is to use T's Lightwire or an equivalent, although that would be the best long term approach for them to take, if they can afford it. At some point these upgrades have to start paying for themselves. T spent over $5,000 per sub when they bought their cable properties. And many of those subs were hanging precariously by a string, resulting from years of neglect by TCI. Fiber to the home, in contrast, is down in the $2,000 to $2,5000 per sub range now. It's something to think about the next time someone has a hundred billion dollars they want to get rid of. FAC

NEW SPATIAL DIVISION MULTIPLEXING TECHNOLOGY DELIVERS FIBER-SPEED, RANGE AND RELIABILITY OVER COPPER PAIRS Actelis Networks' Patent-Pending Technology Will Enable Carriers to Deliver DS3 Services on a Universal Scale FREMONT, Calif., May 29, 2001 -Actelis Networks, the first company to boost copper performance to fiber-quality speed and reliability, today announced that its new patent-pending technology, Spatial Division MultiplexingTM (SDM), has successfully completed its first carrier trial. SDM is the first technology to transform ordinary copper lines into a DS3 (45 Mbps symmetrical bandwidth) transport solution with bit error rates identical to fiber optics. SDM makes ultra high-speed business access available to virtually any copper-fed multi-tenant unit. Additionally, by transforming copper pairs into a powerful DS3 backhaul solution, SDM brings broadband service to the last mile, even in rural areas. "In today's market economy, carriers are continuously challenged to generate more revenue from their existing network assets," said Yuval Baron, president and CEO of Actelis Networks. "The beauty of SDM is that it transforms a carrier's most widely available resource-its installed base of copper plant-into high-speed, next-generation transport, and provides error-free performance without special line pre-qualifications." "The Actelis solution is a natural fit for the telecom marketplace, since so many carriers cannot get last-mile fiber today, and those that can incur steep capital expense penalties during buildout," said Scott Clavenna, president, PointEast Research, located in Cambridge, Mass. "These situations reduce carrier revenue potential, forcing them to limit service to low-bandwidth, low-margin alternatives-or worse-to forgo service altogether to certain subscribers. By allowing carriers to capitalize on their existing copper assets for high-value service delivery, the Actelis solution proves the business case for pervasive broadband deployment." Carrier-Tested, Robust Technology Actelis successfully concluded the first SDM technology trial with North Pittsburgh Telephone Company in May of this year. The SDM trial benchmarked key performance metrics including interoperability, system redundancy, error-free transmission, and signal range in a standard outside aerial cable plant environment. The SDM-powered platform delivered continuous error-free data transport at DS3 rates and demonstrated the capacity to extend well beyond 45 Mbps. "The ability to offer fast deployment of fiber performance transport services introduces a phenomenal opportunity," stated Al Weigand, vice president of North Pittsburgh Telephone Company. "The Actelis solution performed at fiber quality thresholds. The Actelis product will fill an important role in our network architecture," said Weigand. "SDM performed exactly to plan," said Tuvia Barlev, chief technical officer for Actelis Networks. "Deployment was immediate and testing resulted in consistent error-free performance over the entire four-week trial period. The SDM performance standard is unprecedented." The SDM high-speed access technology will allow carriers to transform their existing copper loop plant into a fiber-scale service platform. With close to a billion phone lines worldwide, the copper loop plant is a ubiquitous asset that represents a multibillion-dollar carrier infrastructure. However, cross-talk interference, high error rates, and distance barriers have historically limited the potential of copper for delivering ultra high-speed services. The successful completion of the first SDM trial signifies a new opportunity for carriers. By boosting the speed, range, and reliability of copper pairs, carriers can offer affordable, same day provisioning of DS3 services to virtually any copper-fed remote terminal cabinet or multi-tenant unit. Since no reconstruction of the cable plant is required, revenue generation is immediate. Carriers can minimize risk by delaying investment until demand for service-and consequently revenue-is guaranteed. The SDM-powered platform is the culmination of a two-year research and development effort yielding more than a dozen pending U.S. patents. Actelis recently announced the first closing of its series C funding round, garnering $26 million from Carlyle Venture Partners, New Enterprise Associates, U.S. Venture Partners, Walden International, Global Catalyst Partners, and Vertex Management.
