Network processor integrates programmable Ethernet switch
By Robert Cravotta, Technical Editor -- EDN, June 16, 2008
Xelerated’s next-generation HX300 network-processor family integrates traffic management and fully programmable Ethernet switches. The Ethernet switches target fiber-access-aggregation switches, GPON (gigabit-passive-optical-network) and EPON (Ethernet-passive-optical-network) line cards, and EADs. The HX320 targets CESR, service routers, legacy systems, 100-Gbps GbE (gigabit Ethernet), 40-Gbps GbE, and OC-768 applications. The HX330 integrates a traffic manager for CESR, service routers, GPON and EPON line cards, and xDSL (digital-subscriber-line) aggregation. The Xelerated data-flow architecture scales to 100 Gbps full duplex and can support a QOS (quality-of-service)-aware distributed-traffic-management model for either chassis-based switching systems or meshed configurations.
The HX300 family enables fixed-port, stackable and chassis-based networking systems that you can configure in mesh, ring, star, dual-star, and stackable topologies. The HX300 integrates 100-, 40-, 10-, and 1-Gbit Ethernet ports. It is binary-software-compatible with custom and metropolitan-Ethernet applications for Xelerated’s X10 and X11 network-processor families. The HX300 family will be available for sampling in the fourth quarter of 2008. All devices are available in leaded and lead-free packages with options to support industrial-grade temperature.
