The Alcatel-Lucent Integrated Service Adaptor Ethernet Switch (ISA-ES) series circuit packs provide feature-rich Ethernet service capabilities for the undisputed market leaders of multiservice networks, the Alcatel-Lucent Optical Multi-Service Node (OMSN) products.Alcatel-Lucent ISA-ES16 variants provide native Fast Ethernet (FE) and Gigabit Ethernet (GigE) interfaces and Ethernet over SDH (EoS) ports within a 4.8-Gb L2 switching engine.
The Alcatel-Lucent OMSN family of multi-service nodes is deployed world wide. The Alcatel-Lucent 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 Alcatel-Lucent 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.
The Alcatel-Lucent ISA-ES series meets the Ethernet technology needs of Tier-1 and Tier-2 service providers, service-provider carriers, multisystem operators or mobile service operators (MSOs), cable operators, power utilities and government institutions.Each Alcatel-Lucent ISA-ES module has a configurable IP address and User Datagram Protocol (UDP) port for network management to manage Ethernet services, including implementation, alarms retrieval and QoS performance monitoring (PM).Alcatel-Lucent ISA-ES16 circuit-pack overview • Electrical and optical FE/GigE interfaces, with small form-factor pluggable (SFP) optics• Comprehensive set of:¬ Ethernet switching features (IEEE 802.1D/Q/ad)¬ Resiliency features: xSTP, Link Aggregation Group (LAG), Link Capacity Adjustment Scheme (LCAS), SDH-based protection¬ QoS features: for example, policing, priority marking, per class queuing, weighted random early detection (WRED), weighted deficit round robin (WDRR)¬ Ethernet PM counters¬ Ethernet operations, administration and maintenance (OAM) suite (ITU T Y.1731/IEEE 802.1ag)• EoS adaptation suite, using generic framing procedure (GFP) (ITU-T G.7041), link access procedure over SDH (LAPS), virtual concatenation (VCAT) (ITU-T G.707)• Flexible data architecture options (see Figure 2):¬ Point-to-point¬ Hub-and-spoke¬ Multipoint-to-multipoint• “Bridge none mode” for transparent packet switching¬ Unidirectional/offerirectional point-to-point¬ Unidirectional/offerirectional point-to-multipoint• Multiprotocol Label Switching (MPLS) Martini encapsulation¬ MPLS label switch router (LSR) ¬ MPLS over Ethernet¬ MPLS over SDH (PPP/HDLC/SDH)• Optical transport options within Alcatel-Lucent 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 and MPLS tunnel manager• Hardware-based Electrical Protection Switching (EPS) 1+1 functionality to give maximum resilience on carried traffic.
To help meet service level agreements (SLAs), each Alcatel-Lucent ISA-ES module allows service providers and carrier operators to specify per-flow QoS. Traffic is specified by a set of parameters to control its maximum and mean rates and the relative burst window size in bytes (see Figure 3).Policing parameters are specified according to:• Committed information rate (CIR)• CIR burst window size (CBS)• Peak information rate (PIR) or excess information rate• PIR burst window size (PBS)Supported SLAs in Alcatel-Lucent ISA-ES16:• Guaranteed traffic• Best-effort traffic • Regulated trafficThe Alcatel-Lucent ISA-ES16 Ethernet Switch module supports four to sixteen virtual container (VC)-4s, with aggregate trunking capacity dependent on housing equipment and slot position. The ISA-ES16 switch module services three distinct access-module models, supporting fourteen E/FE ports, seven FX ports, or four GigE ports.
