Riverstone Cites Deployments of its Hitless Protection System

Riverstone Networks said its Hitless Protection System, which enables its switches and routers to continue functioning during software upgrades and system restarts with no impact on live traffic, is gaining traction on large corporate networks that require carrier-class reliability. Riverstone's HPS is currently used in the carrier networks of KT (formerly Korea Telecom), Telefónica de España, Cox Communications and China Netcom. It is also being deployed in large educational networks including the University of Arizona Telemedicine Program, the Dartmouth and Medfield school districts in the United States, the Urasoe school district in Japan and the Anhui province in China. Additionally, the Pentagon is using HPS for networks serving 26,000 military and civilian employees and 3,000 non-defense support personnel.
