Riverstone Networks this week unveiled two access routers designed to lower the cost of delivering business and residential Ethernet services.
The Riverstone 15100 and 15200 Carrier Ethernet Access Routers extend the feature set of Riverstone's higher-end 15008 Ethernet edge router to the access point of the network. This is intended to give service providers the ability to maintain a single operational model, as well as mix and match VLAN and MPLS access technologies -- including VPLS -- to optimize functionality and cost in both large and small network deployments, Riverstone says.
Riverstone claims the routers provide edge and core features at price points closer to access routers. The high cost of edge and core MPLS/VPLS implementations has, until now, precluded service providers from deploying the technologies in the access domain, forcing them to opt for other technologies and compromise on reliability, scalability, QoS and operational consistency, the company claims.
The 15100, available in the fourth quarter, features 20G bit/sec of throughput and supports up to 20 fiber or 10/100/1000M bit/sec copper downlinks, and four 1G bit/sec uplinks.
The 15200, available in the first quarter of 2006, features 40G bit/sec of throughput, 24 1G bit/sec service ports, and dual 10G bit/sec uplinks. Both of the access routers support VPLS, RFC-2547 MPLS-VPNs, and Layer 3 routing protocols, including BGP, OSPF, multicast, and IS-IS.
Both routers are fixed-configuration, 2-rack-unit devices.
