ATLANTA -- The integrated communications leader, Broadwing Inc. (NYSE: BRW), today announced the completion of a national real-time video trial with CNN (NYSE: AOL), the 24-hour news network. The trial demonstrated Broadwing's ability to deliver broadcast quality video over its network, guaranteeing delivery, and prioritization of mission-critical traffic. In the field trial, existing video sources from CNN news bureaus in Atlanta, Los Angeles and Washington, D.C. were connected to the Broadwing network, encoded, and transported across the network as high-quality, video streams. Broadwing used both multicast and unicast IP architectures to deliver real-time video feeds to all three locations. Traffic from each of the bureaus was marked by CNN as "Gold," "Silver" or "Bronze" and delivered in priority order across the network. In the testing, live feeds were given priority over taped events when simultaneously transmitted. During the trial, CNN required Broadwing to deliver both unicast, and multicast content during even the most extreme network conditions without degrading picture quality. "Our successful trial with CNN continues to demonstrate that the Broadwing network is providing our customers with new ways of offering services to their own customers giving them a competitive advantage in their industries," said Jack Chidester, president of Business Enterprises.
