$4.3Bln Internet Sale

NEW YORK -- Redback Networks, a maker of equipment to help Internet service providers transmit data more easily, is acquiring Siara Systems for about $4.3 billion in stock, company executives said Sunday.

Redback makes a box called a subscriber management system that helps Internet service providers, like telephone companies and cable operators, send data quickly over high-speed broad band networks. In buying Siara Systems, Redback hopes that the optical networking equipment and software Siara is developing will turn Redback into one of the first one-stop shops for products needed to run the next generation of computer networks.

Optical networking, which makes it easier to send more information quickly across broad band networks, is all the rage among technology companies in Silicon Valley.
