8/10/2004 - Vitesse Semiconductor Corporation (Nasdaq: VTSS) continued its rapid introduction of triple-speed (10/100/1000 Mbps) Ethernet Media Access Controllers (MACs) to support the industry's transition to copper-based Gigabit Ethernet. Known as the BarringtonTM family, these 24-, 16- and 12-port devices provide system OEMs with a cost-effective solution for seamless scaling of Ethernet line card designs. Vitesse now offers the broadest line of high-density MACs in the industry.
The Barrington family is based on Vitesse’s third generation MAC architecture and includes the flagship 24-port VSC7324, the 16-port VSC7325, and the 12-port VSC7326. Each device has advanced traffic over-subscription mechanisms to ensure quality of service and high bandwidth availability during periods of peak network utilization. Combining this capability with extensive per port buffering, high-density platforms, such as Ethernet switches and routers, can aggregate up to 24 Gigabit Ethernet ports into a single 10 Gbps packet processor. OEMs realize a substantial cost savings by reducing system cost per user without impacting network performance.
Superior Network Management and Efficiency on a Per Port Basis
As the transition to triple-speed copper interfaces in the Enterprise increases, the need for intelligent over-subscription and control traffic protection functionality is critical to efficient network operation and management. The Barrington family includes advanced over-subscription mechanisms, used to control the bandwidth on each Ethernet port in order to prioritize traffic across all 24-ports. As part of the advanced over-subscription mechanisms, the Barrington family also prioritizes and protects Layer 2 and Layer 3 control frames to maintain overall network management and efficiency during periods of peak network utilization.
“Vitesse is committed to driving the rapid market acceptance of Gigabit Ethernet ports for OEM system applications,” said Mark Fauber, director of product marketing for Vitesse’s triple-speed MACs. “The addition of features, such as advanced over-subscription, in the Barrington family is just the latest addition to a product portfolio taking a leading edge approach to solving the demands of high-density, cost-effective Ethernet aggregation systems over existing copper infrastructures.”
The increased port density of the Barrington products allows the Ethernet triple-speed linecards to scale up to densities of 72 or 96 ports. More specifically, the 24-port Barrington device (VSC7324) combines 24 triple-speed RGMII-based ports and an OIF-compliant SPI-4.2 system interface, making it ideal for use in modular Ethernet Switch and Router platforms used in copper-based network, such as Layer 2 and 3 Ethernet Switches, Enterprise Edge and Core Routers, and Modular VPN/Firewall appliances.
This scaling flexibility is essential as the industry adopts Gigabit Ethernet solutions. iSuppli, a leading market research firm, forecasts that the shipments of Gigabit Ethernet ports in switches and hubs will exceed those for Fast Ethernet ports in 2005 by 12 million (70 million vs. nearly 62 million for Fast Ethernet).
Benefits of The Industry’s Broadest MAC Product Line
Over the past 15 months, Vitesse has introduced seven new products in the stand-alone MAC market, beginning with Meigs-IITM, the industry’s first QUADSpeed MAC device combining ten triple-speed ports and a single 10 GbE port to form the industry’s highest density 10 Gbps MAC.
Like its predecessors, the Barrington family continues to enable system OEMs to focus on the value-added features of the packet processing function by simplifying the system interface equation. These devices incorporate the industry standard OIF SPI-4.2 interface for seamless connection to a wide variety of integrated circuits, such as packet processors, traffic managers, and switch fabrics. A single-packet processor solution can support application densities of 12, 16, or 24 triple-speed ports in the Barrington family as well as other port densities and applications using other members of the Vitesse MAC product family, thus lowering overall system implementation costs for the system OEM.
Packaging, Availability and Pricing
All members of the Barrington family operate over the commercial temperature range of 0 °C to +70 °C, and are available in 35mm PBGA packages. Samples are available now with production quantities available in September 2004. The 24-port Barrington device is priced at $144 in volume quantities.
