Greenfield Offers 24-port Metro Ethernet Switch Design

Greenfield Networks, a start-up offering merchant silicon for Ethernet switches, introduced a reference design for a 1RU Metro Ethernet switch supporting 24GbE plus two 10GbE ports with wire-speed performance, per-subscriber quality-of-service (QoS) and Triple Play service capabilities. The design is powered by the company's Packetry II Ethernet switching silicon.

Greenfield said its design delivers wire-speed switching performance with a maximum forwarding rate of 72 Mpps. The platform features 24 copper Gigabit Ethernet and two 10GbE XFP ports in a compact 1RU form factor. It also include Layer 2/3/4 packet processing features and capabilities such as expandable tables and buffering, IPv4, IPv6, MPLS/VPLS/H-VPLS, QinQ, and VLAN translation. GH8000 supports scalable per-subscriber hierarchical QoS critical for enabling Triple Play services. Traffic management capabilities allow service providers to introduce new services such as high-definition IPTV, multi-megabit Internet access, and VoIP.
