Xelerated, which supplies merchant silicon to eight of the top ten Carrier Ethernet systems companies, announced its next-generation HX300 family of high performance network processors with integrated traffic management and fully-programmable Ethernet switches. 
The new silicon, which is designed for fiber access platforms, offers a combination of switching and processing functionality, enabling service-aware applications that readily adapt to changes in network conditions and optimize performance. It could be used in fixed-port, stackable and chassis- based networking systems that can be configured in mesh, ring, star, dual star and stackable topologies. The HX300 integrates 100-Gigabit, 40-Gigabit, 10-Gigabit and 1-Gigabit Ethernet ports. The HX300 is binary software-compatible with custom and Metro Ethernet Applications (MEA) that have already been developed for Xelerated’s X10 and X11 NPU families.
The HX300 leverages Xelerated’s Dataflow packet processing architecture, ensuring wirespeed deterministic performance with programmability. The company said its NPU architecture scales to 100 Gbps full duplex. The advanced standards-based egress traffic management and the tight integration of the Xelerated Dataflow Architecture enables the HX300 family to support a QoS-aware distributed traffic management model for either chassis-based switching systems or meshed configurations. Triple play services are enabled by a flexible queue allocation and programmable hierarchy that enforces per-flow, per-subscriber, per-class Service Level Agreements and bandwidth guarantees.
The HX300 family includes three core series: HX310, HX320 and the HX330. The HX310 consists of programmable Ethernet Switches for fiber access aggregation switches, GPON/EPON line cards, EADs. The HX320 Series is an NPU for CESR, Service Routers, Legacy Systems, 100 GE, 40 GE and OC-768 applications. The HX330 is an NPU with integrated Traffic Manager for CESR, Service Routers, GPON/EPON linecards, xDSL aggregation.
The HX300 family will begin sampling in Q4 2008. All devices are available in leaded and lead-free packages with options to support Industry Grade Temperature. Pricing is available on request.http://www.xelerated.com
