... management, prioritization, and aggregation with Gigabit Ethernet trunk interfaces for cost-effective interworking with Ethernet switches and routers. The MAG devices work seamlessly with Ciena's Service Aggregation Switches—such as the CN 5060 Multiservice Carrier Ethernet Platform, to provide Ethernet ...

... and QoS using service VLANs. This is a much less complicated and much more cost-effective approach than attempting to converge all services over a routed infrastructure. Benefits * Swiftly deliver flexible bundles of scalable data, voice and video services * Benefit from a return on investment in highly ...

... hooks that service providers need to direct packet flows and control resource allocation. Never intended as a general purpose transport solution, router-based IP cannot satisfy service providers' business requirements. When it comes to universal transport, ATM is a much better candidate. Operating at ...

... can happen on demand without affecting other wavelengths and services. CN 4200 ROADM is provided using four key modules: * Dynamic Wavelength Router (DWR) * Optical Channel Monitor (OCM-8) * Variable Gain (Rx) Amplifier (OAV-VS-U-C) * Fixed Gain (Tx) Amplifier (OAF-BC-B) The nine-port, Wavelength Selectable ...

... . Businesses are able to reduce recurring bandwidth costs in environments in which they have access to dark fiber by eliminating costly channelized router ports and WAN conversion equipment with traditional carrier interfaces such as DS-3. Gigabit data connectivity has become a front-line requirement ...

... Video-over-DSL Solution page 2 Legacy DSLAMs and DLCs without true video capabilities utilize co-located IGMP (Internet Group Management Protocol) routers to achieve multicasting. This extra equipment increases costs and results in a solution that is not scalable. Catena's CN1000 BLC provides integrated ...

... such as earthquakes or floods. Path Switching and Line Switching to Provide Signal Recovery Network protection is achieved by providing different routes between the source and destination. In all-optical networks, as in SONET, ring topology is the dominant networking infrastructure providing route diversity ...

... exchange tremendous amounts of data. Even modest hospital groups must transfer more than 100 GB per day—a level of data transfer that IP-routed Wide Area Networks (WANs) have difficulty supporting without significant packet loss and packet retransmissions. Second, database replication is very sensitive ...

In all-optical networks, as in SONET, ring topology is the dominant networking infrastructure providing route ...

... (OADM) elements to address application-specific needs. Integrated OADM elements lower network CAPEX and OPEX by allowing a single, longer distance route to replace multiple shorter segments. Within the same DWDM route, wavelengths can be provisioned to cover the entire route or any portion of the route ...
