The Metro Ethernet Forum (MEF) set the groundwork for Carrier Ethernet by defining five attributes to distinguish it from traditional LAN Ethernet. These include: standardized services, scalability, reliability, quality of service (QoS) and service management. These attributes bring carrier-class capabilities to traditional LAN Ethernet, adapting it for cost-effective use as a WAN and MAN technology. While Carrier networks consist of many transport technologies, and will continue to do so for the foreseeable future, the next-generation of Carrier Ethernet equipment will need to enable the true transition from TDM to packet-based networks in a way that allows carriers to maintain and upgrade service levels while controlling operating costs. What will make this possible? IC solutions that are specifically designed to support Carrier Ethernet will be essential to the evolution to next-generation networks.

Making Next-Generation Networks a Reality Vitesse ICs address these Carrier challenges, the largest of which is to transition their networks to Ethernet services over multiple existing and emerging transport technologies. With over two decades of experience in LAN and WAN technologies at the physical layer, as well as in Layer 2 and Layer 3 protocols, Vitesse has delivered network transition solutions to the market for many years. With its family of PHYs, MACs and Ethernet-over-SONET (EoS) mappers, Vitesse ICs have eased the migration path to Carrier Ethernet, with design wins among nearly all T1 customers. Vitesse ICs enable carrier equipment to deliver services end-to-end, over any network, thus protecting past investments and allowing a seamless migration to next-generation networks.
