Resumen del manual
These capabilities provide a cost-effective solution for building multiservice aggregation infrastructures that are scalable, reliable and capable of per-service SLA/QoS support with: • Scalable service delivery based on virtual local area network (VLAN), Q-in-Q or MPLS technologies, extended by efficient SDH bandwidth- management capabilities • Sub-50 ms service resilience based on SDH • Per-flow and per-service SLA guarantees offer accurate bandwidth profiles according to different customers’ applications, to create a measurable, differen tiated Ethernet service portfolio and increase service profitability by ensuring QoS-specified Ethernet service delivery in any network condition, including faults and congestion. The ISA-ES blades allow service providers to deliver more than just Ethernet connectivity service over the optical metro infrastructure. These modules enable service providers to climb up the value chain and offer the new revenue-generating services that both business and residential users are demanding. Alcatel-Lucent OMSN Product Family Alcatel-8 Lucent OMSN Product Family The multiservice capability of the Alcatel-Lucent OMSN nodes equipped with the ISA-ATM blades offers mobile service providers a cost-effective solution for 3G mobile aggregation in the UMTS terrestrial radio access network. ISA-ATM switching blades can consolidate ATM traffic collected from different Node B access devices onto shared SDH virtual container (VC) resources in STM-n rings, and switch the ATM traffic into the network with QoS support for all traffic classes. Traffic-policing, shaping and congestion-control management features allow a complete range of ATM traffic contracts. For increased service manageability, ATM OA&M capabilities provide end-to-end fault management and performance monitoring. Figure 3.

The 3G mobile-aggregation application is a key example of how service providers can benefit from the ATM switching integrated into the Alcatel-Lucent OMSN products (see Figure 3).

In the past, video transmission across wide metropolitan areas required a costly overlay network separate from voice and data networks due to a lack of digital-video interface standards designed for WAN transport. The deployment of the DVB-ASI, together with the packet-adaptation capability offered by the frame mapped generic frame procedure (GFP-F), allow packetbased transmission of compressed video signals, including DVB-S, DVB-H, DVB-T and DVB-C over the Alcatel- Lucent OMSN product family (see Figure 4). Storage area networks Enterprises worldwide rely on complex informationtechnology computer structures to store and maintain their mission-critical data and applications. In this scenario, storage area networks (SANs) are the telecommunications industry’s solution for improving the availability, resiliency, performance, modularity and geographical distribution of storage systems, offering corporations superior capacity and connectivity for their vital information systems. The Alcatel-Lucent 1660 SM and Alcatel-Lucent 1662 SMC address SAN applications in metro environments. Their wavelength division multiplexing (WDM) features, together with the native interfacing capabilities of the 4 x any modules for specific storage applications, including ESCON, FICON and FC, make them a flexible solution for interconnecting local networks to a centralized storage network, reducing the data-management costs.
