When it comes to broadcast networks, is SONET/SDH ready for prime time?

摘要

Broadcasters use fiber-based networks to transport live and taped programming to and from remote locations, central offices, and affiliates today more than ever. This is not an isolated development; it affects how broadcasters deliver programming and what viewers expect from video-related services. Professional media services have unique and demanding transport requirements. Even the financial sector, where split-second execution can mean the difference between profit and loss, doesn't come close to the broadcast industry's quality of service (QoS) requirements. Broadcasters need to send high-bandwidth video files and real time video streams among multiple locations with guaranteed delivery.
