Nokia's TPSDA allows network operators to progressively integrate their HSI, voice, and video services within a unified and homogeneous Ethernet-based aggregation network environment. The key benefits of the proposed service infrastructure include cost optimization, reduced risk, and accelerated time to market for new services.
At a high level, TPSDA implements:
Ethernet-based service architecture
This architecture solves bandwidth bottlenecks and exponential capital expenditure and operating expenses issues in the second mile by leveraging the efficiency of this technology.
multiple distributed service edges
This feature allows service providers to achieve faster times to market for new services while retaining the existing Broadband Remote Access Server (BRAS) and Point-to-Point Protocol over Ethernet (PPPoE) mode of operation for wholesale and retail HSI.
distributed multicasting functions in access and aggregation networks
This feature enables service providers to optimize bandwidth and content delivery mechanisms, based on densities and penetration rates. It is also essential to subscriber and service scaling, and optimizes the bandwidth required in the aggregation network.
carrier video and Voice over Internet Protocol (VoIP) services using Dynamic Host Configuration Protocol (DHCP)
This feature enables service providers to introduce plug-and-play services delivered through set-top boxes and VoIP devices, which are designed for use with the DHCP.
flexible deployment models
The architecture allows data, video, and VoIP services to be rapidly rolled out without any lock-in to specific operational models. It allows service providers to maximize flexibility and minimize financial and technological risks by allowing all modes of operation, including:
copper (DSL/DSLAM) and fiber-based (FTTx) deployments in the first mile
single or multiple last mile circuits
bridged or routed home gateways
single or multiple IP address deployment models
