Broadcom Corp. unveils a line of low-power, high-performance Ethernet switches for service provider networks. The carrier-class switches allow mobile and broadband service providers to deploy a new generation of high performance network infrastructure equipment with substantially lower capital and operational expenditures. Broadcom's standard silicon solutions support the complex protocols and bandwidth requirements for service providers as they look to simultaneously deliver both mobile and broadband services across a single IP backbone.

The global explosion of mobile devices, bandwidth-hungry applications and consumer demand for 24/7 connectivity to IP-based video, social networking and location-based services are overwhelming today's mobile networks. Service providers are now challenged to provide 'on demand' connectivity and a better user experience on 3G and future 4G networks or risk the loss of high revenue generating subscribers. To meet these performance needs, networking OEMs must quickly bring to market low cost, data-oriented mobile backhaul equipment.

Traditionally, slow TDM-based mobile backhaul equipment was built using costly custom ASICs, FPGAs and/or disparate components from niche suppliers. This design model, however, results in sub-standard equipment that is expensive, has a lengthy time-to-market and is not suitable for data and video. Ethernet ASSPs provide optimized bandwidth at the lowest cost for this application.

The latest Broadcom Ethernet switch products are optimized to reduce capital and operational expenditures. These solutions now enable service providers to manage broadband and mobile connectivity simultaneously on a single network with complete product interoperability.

Broadcom service provider switch products deliver on the three key design principles of consistency, scalability and quantity.

Consistency is important because advanced protocols must deliver efficient end-to-end provisioning of revenue generating services, and also facilitate easier network manageability. Broadcom's service provider switch portfolio offers a common set of features and protocols for every step in the network, minimizing operational expenditures and reducing cost of ownership.

Scaling demands vary dramatically across the service provider network. Broadcom offers a wide variety of service provider switch products that are optimized to scale to the appropriate level at each point in the network. Providers require this range of scalability not only to achieve high performance in the core, but also to address the cost concerns associated with edge equipment which must support a high number of cellular sites.

As for quality, providers must demonstrate that their networks adhere to contractual service level agreements. Broadcom designs and tests its switch silicon to meet the field performance demands of the service provider market. In addition to rigorous test and manufacturing methodologies, Broadcom devices incorporate extensive resiliency mechanisms, performance monitoring capabilities and traffic management services.
