Organizations are bumping up against the capacity limits of legacy frame relay and private line networks, causing them to seek higher bandwidth, and next gen access options like Ethernet and optical networks are an attractive alternative," said Michael Howard, principal analyst at Infonetics Research.

The EtherDAX 6000 provides a seamless migration from TDM based frame and private line network technologies via Ethernet over SONET using industry standard X.

Typical network segregation points include: * network perimeters where internal and external networks converge, such ns the DMZ; * network edges where two non-routable networks interconnect; * network edges where two private but different physical networks interconnect, such as private wireless LANs and private wired LANs, private line networks and private satellite links; and * network boundaries where two private but different security level networks interconnect, such as the corporate LAN and a private server farm network.

Frame relay service can cut the cost of private line networks by 50% or more.

The complete Ethernet private line network solution Broadwing developed for GameRail is further enhanced with an optical hand-off to GameRail's deployment of high availability Extreme Network switches which deliver packets at line speed with non-blocking hardware and exceptional Quality of Service (QoS).

has interconnected its virtual private line networks service with British Telecom's International FeatureNet service to provide its customers with a number of new features and direct access to international destinations and overseas virtual private networks.

Customers eager to embrace IP-enabled converged solutions will benefit from Broadview's multi-service MPLS-based Virtual Private Networks for secure private data exchange, with significant savings compared to Frame Relay and traditional point-to-point private line networks.

Almost any article or discussion about networks begins with the premise that today's private line networks are no longer economical and will eventually be replaced by "software-defined" or "virtual" networks.
