Broadband Aggregation for Triple Play
Introducing triple play services establishes new requirements for the broadband-aggregation infra- structure for both scalability and the speed of service rollout. To meet these goals, many service providers are introducing Ethernet into their broadband-access infrastructures. This type of infrastructure allows network service providers to progres- sively integrate their triple play services into a unified and homoge- neous environment.
The Alcatel-Lucent 1850 TSS-320 can provide efficiently distributed broadband service aggregation and transport toward the broadband
service routers. The Alcatel-Lucent 1850 TSS-320 is a unified transport platform, offering fexible support during the transition from legacy transport to Ethernet. The unified aggregation platform supports any multiservice business model and protects infrastructure investments. For distributing video, it is important to broadcast these services from the last possible point in the network to avoid costs from duplicating services inside the network. With a dedicated Ethernet network or a multiservice network, the multicast can be done efficiently at either the TDM or Ethernet level. The Alcatel-Lucent 1850 TSS-320 can use a combination of distributed Layer 2 and TDM switching, depending on the option that suits the provider’s requirements and minimizes costs.
Ethernet Business Services
Enterprises are increasing their use of high-bandwidth applications and they are more frequently intercon- necting LANs and data centers within a metro area. To address this market, service providers need scalable, carrier- class solutions that offer guaranteed quality of service (QoS) levels, support for differentiated service level agree- ments (SLAs) and customer separation. Service providers can build either dedicated Ethernet networks or multiservice networks able to provide other services through the same networking platform. The Alcatel- Lucent 1850 TSS-320 supports both of these network models.
