Laurel Networks introduces ST200 Broadband Software Module with Service Separation and Blending
15 May 2003 Pittsburgh, PA Lightwave -- Laurel Networks Inc., provider of high-performance service edge routers, recently introduced its Broadband Remote Access Server (BRAS) software module for the ST200 Service Edge Router. According to the company, the ST200 is the first BRAS with Service Separation and Blending (SSB), a key innovation required to deliver advanced broadband services over a single customer connection.
15 May 2003 Pittsburgh, PA Lightwave -- Laurel Networks Inc., provider of high-performance service edge routers, recently introduced its Broadband Remote Access Server (BRAS) software module for the ST200 Service Edge Router. According to the company, the ST200 is the first BRAS with Service Separation and Blending (SSB), a key innovation required to deliver advanced broadband services over a single customer connection. SSB includes the high bandwidth-per-subscriber, advanced quality of Service (QoS), and integrated routing and switching required for multimedia broadband service delivery.
SSB moves broadband providers from basic high-speed Internet access to a complete portfolio of business and consumer broadband services, including Internet-Protocol (IP) Virtual Private Networks (VPNs), packet voice, video-on-demand, broadcast TV, gaming, and music. SSB uses sophisticated QoS to blend packets from multiple services downstream over a single broadband customer connection, while intelligent switching and routing separate upstream traffic to different content or service providers.
"By integrating SSB into the ST200 system silicon, we have broken through the architectural challenges of multimedia broadband service delivery," contends Steve Vogelsang, Laurel Networks co-founder and vice president of marketing. "Broadband providers can now offer all types of multimedia-intensive, high-bandwidth services by integrating the ST200 into their existing infrastructure."
The ST200 BRAS Software Module key features include:
Advanced QoS for service blending: Only the ST200 features the per-service queuing and shaping needed to guarantee delivery of delay-sensitive multimedia applications and high-speed Internet services on a single connection, claims the company.
Integrated routing and switching for service separation: Unlike traditional BRAS platforms, ST200 integrated routing and switching provides the intelligence needed to separate packet streams across multiple content networks.
Highest bandwidth-per-subscriber enables multimedia services: According to the company, the ST200 delivers the highest bandwidth-per-subscriber with advanced features enabled, a requirement to profitably deliver multimedia services to large numbers of users. The ST200 supports over 100,000 broadband sessions with classification, filtering, IP VPNs, multicast, and QoS features enabled. The architectural limitations of other BRAS platforms restrict multimedia support or result in performance degradation as providers turn on advanced features.
Multicast scalability supports new broadcast services: With multicast support for over 500 channels and 100,000 subscribers, the ST200 is the first BRAS with the scale required to distribute a mix of broadcast video and audio channels to thousands of subscribers over DSL, say Laurel representatives.
Integrated bandwidth control simplifies broadband service architecture: Integrated ST200 per-subscriber bandwidth control eliminates the need for external bandwidth managers such as ATM switches. The flexible ST200 also seamlessly connects into existing broadband infrastructures, allowing providers to immediately begin offering new broadband services.
High-speed interfaces enable high-bandwidth services: The ST200 supports ATM access interfaces at DS-3 through OC-48 speeds (critical for connecting to ATM DSLAMs), while Gigabit Ethernet interfaces provide connectivity to lower-cost alternative access technologies. Laurel claims its ST200 is the first BRAS with OC-48 and OC-192 uplinks.
The ST200 BRAS software module is in trials now with multiple broadband service providers and will be generally available in the third quarter of this year.
