…or beyond the headend, rather than locally or at another d-hub on the same ring. Metro networks designed as packet rings (e.g. routers connected hop-by-hop at each hub) waste capacity and degrade service quality. Solution You need a more simplified, scalable and cost-effective CMTS transport architecture…

…over a single optical infrastructure and converge around IP packet networks without the complexity and expense of putting routers at every network hop. “Ciena has built a true carrier-grade packet switch with full redundancy, integrated optical protection switching and separation of the data and…

…increased flexibility to meet the needs of customers requiring additional capacity and network service points. “Ciena helped us make the longest hop in our network to date, so not only can we now reach more businesses and destinations, but we also can provide better service to our customers through…

…from NASA?s Goddard Space Flight Center in Maryland, and running across multiple hops back to the SC11 show floor across Internet2 and ESnet 100G links (see the detailed network diagram below).  One of those hops includes a Ciena 5410 located at at StarLight International/National Communications…

…networks that use Layer 3 mechanisms for re-routing around failures take precious seconds to restore connections, and they require excessive router hops, which can degrade the QoS levels required for real-time voice calls while adding cost. Solution By implementing Optical Ethernet switching and transport…
