…high-density Gigabit Ethernet (GbE) and Ten Gigabit Ethernet (10GbE) connectivity to subscriber edge and first-tier aggregation switches, and high-performance 10GbE uplinks to IP/MPLS core switch/routers. With its 1 Tb/s full duplex capacity today, the system can easily accommodate future line modules…

…-generation (i.e. 16 wavelength) DWDM systems lack the scalability to handle the growth of Video On Demand (VOD) and Internet video. Legacy service edge routers and BRAS systems lack the Quality of Service (QoS) to reliably support anything but best-effort Internet access. And traditional broadband access…

…facility. Multi-protocol Label Switching (MPLS) A method used to direct data traffic in networks in which IP over ATM is being used. In MPLS, IP routers at the edge of the network label packets in a way that greatly facilitates their handling by ATM switches at the network core. Multiple System Operator…

…from the edge/metro network to the TDM core or an MPLS core network. Edge/Metro network service aggregation and forwarding to a data core traditionally is supported by a combination of multiple ADMs/MSPPs and/or Ethernet switches for aggregation and TDM traffic forwarding plus edge routers for data traffic…

…more dynamic and efficient. • In analysis of existing network models, Ciena research shows that 30-60 percent of traffic through a typical core router site is transit traffic that does not need to be routed. Therefore, managing this traffic with a broader mesh of OTN switching and connection oriented…
