Vitesse's Director of Carrier Ethernet Technology discusses the importance of Service Management Operations, Administration and Maintenance (OAM), a critical attribute that must be supported in Ethernet, packet-based networks.


CAMARILLO, Calif.--()--Vitesse Semiconductor Corporation (Pink Sheets: VTSS), a leading provider of advanced IC solutions for Carrier and Enterprise networks, has expanded its Carrier Ethernet portfolio to include scalable Layer-3 (L3) routing and MPLS switching support in its new Tiger™ (VSC7480) switch engine. Complementing Vitesse’s previously announced Jaguar™, LynX™, and Caracal™ switch engine solutions for Carrier access and mobile edge applications, Tiger is ideal for scalable service and backhaul aggregation, cloud computing, video, smart-grid, IPTV, IP routing, optical line termination and gateway applications.

Tiger combines advanced processing and switching features with packet processing flexibility, IP routing and VPN, service and forwarding table scalability, and Carrier-class availability and reliability. It includes a 100G bi-directional advanced packet processing engine, which supports IPv4/v6 L3 routing, MPLS switching, advanced multicasting and tunneling protocols. This functionality enables delivery of Layer-2 (L2) and L3 VPN services over a Carrier network. Tiger also offers hierarchical Quality of Service (HQoS), as well as scalable, flexible forwarding and routing profile management for different applications. This provides a lower power and more cost effective alternative to NPUs for scalable network equipment design.

As the protocol infrastructure of both wireless and wireline networks converges to a unified Ethernet packet-based system, heavy network loads and complex traffic mixes compound demands on these networks. Essential to enabling applications such as streaming multimedia are scalable and cost effective L2 and L3 switch solutions at various points in the network. To enable the Service Level Agreements (SLAs) required by service providers, these switch engines must be capable of providing reliable priority to real-time traffic flows and HQoS traffic.

“Service provider and Enterprise applications demand scalable Layer-2 and Layer-3 service creation and service management capabilities in the aggregation network with strong hierarchical QoS features in order to offer multi-service IPTV, Voice Over IP, and multi-tiered VPN services,” said Jag Bolaria, senior analyst at the Linley Group. “Vitesse continues to specifically address important service provider needs with its Ethernet Switching product line. We are excited to see highly integrated, high-volume IC solutions such as Tiger that address these needs.”

Unique Services-Oriented Hardware and Software Architecture

Tiger augments Vitesse’s entire line of Carrier Ethernet products specifically designed with a rich set of advanced Service Provider features, such as Synchronous Ethernet, IEEE 1588v2, protection switching, hierarchical traffic management, and Operations, Administration, and Maintenance (OAM) functions including Y.1731 Performance and Fault Management. Tiger also includes other functions critical for L3 networks, such as HQoS through flow policing of up to 64k independent traffic flows. The switch delivers low latency and low jitter to allow the creation of guaranteed SLAs needed in Carrier applications.

Tiger offers as many as 48 1G ports and eight 10G ports, which can be configured as 48 x 1G + 4 x 10G or 8 x 10G or other combinations. With its optional external SRAM and TCAM, the switch engine supports up to a million MPLS labels and IP routes. The flexible port configurations and advanced IP/MPLS features allows customers to get more reuse and higher return on their investment. Providing a service oriented architecture scalable from low end to high end, Vitesse makes software development simpler and less costly to maintain for its customers.

“Vitesse enables a full range of scalable and cost-effective Layer-2 and Layer-3 solutions with the addition of Tiger to our highly successful line of Carrier-grade Ethernet switch engines and MACs,” said Uday Mudoi, director of product marketing for Vitesse. “With its unparalleled performance and fault management, Ethernet protection and other Carrier critical features in a single, scalable platform, Tiger sets a new standard for Ethernet service delivery.”

Availability and Samples

Samples of Tiger (VSC7480) are generally available now, with volume production scheduled for the second quarter of calendar 2011. More information about Tiger can be found at:

A complete reference design is available, which Vitesse will demonstrate in booth #306 at the upcoming MPLS & Ethernet World Congress in Paris, France from February 8-11, 2011.
