Backgrounder: What the Industry Is Saying About AccessLan's i-SLAM and Internet Scaling Architecture.Business Editors/High-Tech Writers SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--March 27, 2000 AccessLan today unveiled a new class of IP-smart intelligent DSLAM (DSL Access Multiplexor) A central office (CO) device for ADSL service that intermixes voice traffic and DSL traffic onto a customer's DSL line. It also separates incoming phone and data signals and directs them onto the appropriate carrier's network. See DSL. , the i-SLAM and announced Internet Scaling Architecture that will allow the delivery of end-to-end IP QoS. The following are quotes from industry experts regarding today's announcements: "The scalability problem in provisioning PVCs to enable DSL-based services is quite acute and one that Transbeam has faced as an ISP (1) See in-system programmable. (2) (Internet Service Provider) An organization that provides access to the Internet. Connection to the user is provided via dial-up, ISDN, cable, DSL and T1/T3 lines. and as a Northpoint and Covad Reseller. AccessLan's i-SLAM and ISA (1) (Instruction Set Architecture) See instruction set. (2) (Interactive Services Association) See Internet Alliance. (3) (Internet Security and Acceleration) See .NET. provide an attractive solution not only to the provisioning problem, but also laying the QoS foundation for value-added Internet-based services." Marc Sellouk Chief Executive Officer Transbeam, Inc. "The DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary industry is entering the third phase of expansion -- the first phase was driven by Internet access See how to access the Internet. ; the second by VoDSL. The third phase is characterized by delivery of Internet-based packaged applications and streaming content and will drive the industry to new levels. The requirement to deliver these Internet-based services -- application hosting, streaming content, etc. -- and to classify, prioritize and provide QoS management for each application stream imposes a new set of stringent requirements on DSLAMs. AccessLan's i-SLAM approach, with IP QoS management and scalability using MPLS (1) (MultiProtocol Lambda Switching) The earlier name for GMPLS. See GMPLS. (2) (MultiProtocol Label Switching) A standard from the IETF for including routing information in the packets of an IP network. is clearly designed for the third phase." Michael Howard
Principal Infonetics Research "The advent of DSLAMs started to shift the first level of IP Services aggregation out of backbone switches and routers to DSLAMs, in the public network. Therefore, it's no surprise that MPLS, the IP/ATM integration architecture adopted by the backbone switch and router vendors should now be integrated into DSLAMs. As the public network continues its inevitable migration from circuits to packets, the emphasis in the DSLAM market clearly needs to be on Internet and IP functionality. An IP-aware and IP-smart, Intelligent DSLAM to build a scalable IP services aggregation architecture is the key building block for the new public network as it migrates from layer-2 broadband switching to terabit routers for IP services handling." Nicholas Lippis Independent Industry Analyst (about the i-SLAM) "Service Providers should take a serious look at AccessLan's ISA for the scalability and IP QoS management capabilities it offers for delivery of streaming content and application hosting services. When evaluating DSLAMs, or i-SLAM, they should consider if the layer-2 DSLAM platform they are evaluating will require a fork-lift upgrade to deliver differentiated internet access, streaming content and application hosting services. AccessLan's promise to deliver this functionality on existing platforms warrants serious consideration for those making a DSLAM selection." Nicholas Lippis Independent Industry Analyst (about the Internet Scaling Architecture) "As service providers begin to acquire large numbers of DSL subscribers, the support of these subscribers in the core of their network becomes more complex. As these service providers migrate to enhanced service Enhanced service is service offered over commercial carrier transmission facilities used in interstate communications, that employs computer processing applications that act on the format, content, code, protocol, or similar aspects of the subscriber's transmitted information; offers in addition to basic broadband connectivity, the internal setup requirements must be minimized for success." Claudia Bacco Vice President of DSL Consulting TeleChoice, Inc. "With the rapid growth in DSL market, service providers are going to look more at layer 3 solutions since provisioning Layer 2 PVCs on a wide commercial scale will no longer be tenable ten·a·ble adj. 1. Capable of being maintained in argument; rationally defensible: a tenable theory. 2. . AccessLan's i-SLAM, the company's IP-aware DSLAM platform, incorporates ATM and IP QoS extending DSL provisioning flexibility to next-generation service providers that are aggressively pursuing the deployment of differentiated, value-added broadband services See broadband and broadband service provider. ." Ron Westfall Senior Analyst Current Analysis "The vision of IP-intelligent DSLAMs as the logical next step in access concentrators and the consequent development of their Internet Scaling Architecture show that AccessLan has clearly built on its leadership and experience in the Voice over DSL market." Hank Allard Principal Edge Media "AccessLan offers an interesting blueprint for a third-generation DSLAM with its i-SLAM concept because it offers not only traffic aggregation but also traffic classification into MPLS virtual circuits. The company addresses the scalability issues at several layers and provides a pragmatic approach to offering Quality of Service assurances needed for good voice quality." William Flanagan William Flanagan (August 14, 1923 – September 1, 1969) was an American composer of the mid-twentieth century. Flanagan was a great admirer of Ravel and Aaron Copland, who became something of a mentor. His best work was in the realm of vocal music. Program Director The Burton Group "Over the past few months, a large number of ICPs have begun building their own DSL infrastructure primarily to deliver VoDSL. AccessLan's ISA addresses how these service providers can build their own retail Internet services architecture without an external subscriber management system. Moreover, the ISA makes possible dynamic, provision-free service creation, which can eliminate the cumbersome, resource-intensive task of PVC PVC: see polyvinyl chloride. PVC in full polyvinyl chloride Synthetic resin, an organic polymer made by treating vinyl chloride monomers with a peroxide. provisioning for each particular subscriber and service."
