SANTA CLARA, Calif., Jan. 9 --Riverstone Networks Inc. announced that PowerComm Corp., a subsidiary of Korea's National Electric Power Corp., will deploy more than 1000 advanced Riverstone service-creation routers in the greater Seoul area, becoming the the first national telecommunications carrier to deploy an all-Ethernet metropolitan area network. PowerComm's network will unify its cable and last-mile Ethernet subnetworks, allowing the national carrier to offer its own advanced telecommunications services while leasing the network to other service providers in Seoul and neighboring communities. PowerComm will deploy interlinked RS 38000 aggregation routers in its metro core and RS 1000 and RS 3000 access routers in its metro edge. In addition to offering its own Internet-based services to compete with traditional legacy service providers, PowerComm will lease its network to local broadband service providers. PowerComm has installed over 60,000 km of optical fiber throughout Korea.
