Riverstone Intros Line-Card Architecture

SANTA CLARA, Calif. -- Riverstone Networks, Inc., (Nasdaq: RSTN), a leader in service creation infrastructure for metropolitan area networks, today debuted its new line-card architecture, centered on a wire-speed, programmable packet-processing engine. Marking a significant advance in metro networking technology, the first line cards to implement the new architecture provide full Multi-Protocol Label Switching (MPLS) capabilities over a Gigabit Ethernet interface. Future updates to the packet-processing engine will support VPN technologies such as Generic Routing Encapsulation (GRE) and IP-IP tunneling, ATM, and frame relay over MPLS. The capabilities and programmable nature of the new line-card architecture, coupled with Riverstone’s existing metro area technologies, guarantee the new products a central role in the future of metro network deployments.

“By using a programmable line-card architecture to implement MPLS, Riverstone protects ROI by enabling service providers to upgrade their products in the field as standards evolve,” said Kevin Mitchell, directing analyst of service provider networks at Infonetics. “Riverstone’s MPLS-enabled products allow established carriers to supplement their current equipment with Ethernet offerings that map switched paths between networks and have high bandwidth performance characteristics.”
