Anleitung Zusammenfassung
The Alcatel-Lucent OMSN family of multisevice nodes are deployed worldwide. The ISA–ES modules, with their capability to aggregate and switch Ethernet into SDH transport, offer service providers a powerful tool to leverage their SDH investments to offer Ethernet services. Carrier-grade Ethernet must conform to stringent performance standards with high availability and layered network and service management. SDH infrastructures built on the Alcatel- Lucent OMSN products have powerful Quality of Service (QoS) management with high availability and resiliency. Integrated Ethernet services based on the ISA-ES are simple to implement with embedded end-to-end data-service management. The ISA-ES empowers network transformation for service providers seeking to gain maximum return from their network investments (see Figure 1).

Each ISA-ES module has a configurable IP address and User Datagram Protocol (UDP) port for the network management to manage Ethernet services, including implementation, alarms retrieval and QoS Performance Monitoring (PM). ISA ES1 and ES4 circuit-pack overview • Electrical and optical FE/GigE interfaces, with Small Form Factor Pluggable (SFP) optics • A comprehensive set of: ¬ Ethernet switching features (802.1d/Q/ad) ¬ Resiliency features: xSTP, Link Aggregation Group (LAG), link capacity adjustment scheme (LCAS) and SDH-based protection ¬ QoS features: for example, policing, priority marking, per class queuing and WDRR ¬ Ethernet PM counters ¬ Ethernet Operations, Administration and Maintenance (OA&M) suite (ITU-T Y.1731/IEEE 802.1ag) • EoS adaptation suite, using generic framing procedure (GFP) (G.7041), link access procedure over SDH (LAPS), vitual concatenation (VCAT) (G.707) standards • Flexible data architecture options (see Figure 2): ¬ Point-to point ¬ Hub and spoke ¬ Multipoint-to-multipoint Figure 3. SLA support Aggregate E/FE Aggregation/broadband access • Optical transport options within OMSN products: ¬ Multiplex section protection (MSP): 1+1, 1+N ¬ Multiplex Section-Shared Protection Ring (MS-SPRING) 2f ¬ Subnetwork Connection Protection (SNCP) I/N • Efficient network management with dedicated Ethernet manager suite To help meet service level agreements (SLAs), each ISA-ES module allows serv- ice providers and carrier operators to specify per flow QoS. Traffic is specified by a set of parameters to control its maxi- mum and mean rates and the relative burst window size in bytes (see Figure 3).

The ISA-ES1 supports three (3) or eight (8) E/FE ports and the ISA-ES4 supports eight (8) E/FE ports and one (1) GigE port. The ISA-ES modules can be configured to support a wide range of VC-12, VC-3 and VC-4 combinations for flexible, full featured Ethernet over SDH. Figure 6 charts the aggregate bandwidth transported for various VC-X x Nv VC concatenation combinations on an ISA-ES. Table 1 presents a detailed view of the ISA-ES capacities in terms of maximum VC- 12/3/4, VC groups (VCG) by VC-12/3/4 and VC-12/3/4 per VCG. Hosting from one to several ISA-ES cards, the possible OMSN equipment configurations are outlined in Tables 2 and 3. The total number of Ethernet (Eth)/FE per node is directly related to the number of hosted ISA cards. Where larger quantities of Eth/FE ports are required, the Alcatel-Lucent 1850 Transport Services Switch (TSS) family is an ideal fit. Tables 4 and 5 present a detailed view of the available ISA-ES modules and the Alcatel-Lucent OMSN equip...
