Extreme Networks announced that it has been selected by Korea Telecom to provide the infrastructure for its Kornet ADSL network, providing fast and reliable broadband Internet access.

Kornet provides network services including DSL, leased line services, and traditional PSTN services to business customers throughout the region. To prepare for emerging applications and sustain its growth, Kornet has upgraded its network infrastructure with Extreme Networks' BlackDiamond core Ethernet switch-routing solution.

Korea's Internet infrastructure consists of a centralized architecture requiring traffic to run over a number of centralized routers. Extreme Networks' BlackDiamond switch within the core backbone, allows interoperation between local routers and various service routers with Ethernet, tying separated backbones into a single logical backbone to give high reliability while minimizing the changes of existing routing paths.
