Bay Networks Introduces DSL Services Concentrator
Product Will Take ATM Bridged Traffic from DSLAMs And Convert to IP Packets for Routing to an ISP
SANTA CLARA, Calif.--(BUSINESS WIRE)--April 1, 1998--Bay Networks, (R) Inc. (NYSE:BAY - news) today announced the introduction of the Bay Networks DSL Services Concentrator designed to act as a gateway that connects layer 2 DSL networks to revenue producing IP services. The DSL Services Concentrator software enables Bay Networks' Backbone Node (BN(R)) routers to offer leading ATM-based DSLAMs a connection to high-speed IP networks.
Offering the highest scalability in the industry -- 2048 Permanent Virtual Circuits (PVCs) per slot - Bay Networks' DSL Services Concentrator has been tested with a series of the industry's leading DSLAM products.
''With our highly scalable architecture, Bay Networks is capable of supporting over 20,000 users per DSL Services Concentrator,'' explained Sally Bament, vice president of product management for Bay Networks Routing and Protocol Division. ''This translates into savings as service providers roll out the DSL network.''
Leading DSL equipment vendors today offer DSL CPE that function as bridges and transmit user data over the DSL link using ATM RFC 1483 protocol. A central DSLAM aggregates the incoming bridged ATM traffic from these CPE devices and grooms subscriber traffic onto an OC-3 ATM link. As part of the Bay Networks DSL Services Concentrator offering, the third party DSLAM OC-3 ATM link can be handed off to a Bay Networks BCN(R) router. The DSL traffic is simply bridged until it reaches the Bay Networks equipment where it is converted to IP packets suitable for routing through to the Internet.
In addition, the Bay Networks DSL Services Concentrator enables service providers the opportunity to offer value-added services such as VPNs. Bay Networks' gateway solution is also completely independent of the physical DSL layer.
''We are completely independent of the DSL modem technology that is used on the access side,'' said Kelly McGovern, vice president of marketing, Bay Networks Internet/Telecom Business Group. ''As the industry decides on a DSL standard, Bay Networks' solution is interoperable with, and independent of, the physical DSL protocols.''
Features of Bay Networks' DSL Services Concentrator include Dynamic Learning Mode, allowing the host station's MAC and IP addresses to be learned automatically by gleaning IP and DHCP packets; and Source Based Routing which routes packets directly to a gateway address (ISP router) based on source IP address rather than destination IP address.
Realizing the importance to telcos that the network infrastructure for DSL be ATM-based -- although applications and the Internet are IP-based -- Bay Networks' DSL Services Concentrator bridges the gap between the transport and applications networks.
Additional enhancements already being planned for Bay Networks' DSL Services Concentrator will enable service providers to improve their offerings in billing/ accounting, IP services for VPN and QoS offerings. |
