Capacity Demands on Metro Area Networks: How GigE Constructs a Bridge to Advanced Services

摘要

MSOs have been moving toward regional consolidation of systems, and leveraging economies of scale by centralizing operations. This metro area network (MAN) structure eliminates redundant hardware such as receivers and other equipment needed to generate broadcast cable feeds. However, it introduces a need for additional transport from the central headend to local sites to distribute these feeds. Increasingly, cable operators are turning to gigabit Ethernet (GigE) solutions to supply this additional transport.
