Broadband Access Network
End-to-End Broadband Service Performance Monitoring Is Critical for Quality Triple Play Delivery
Overview
Internet Protocol (IP) offers broadband service providers a medium with which to widely deliver voice, Internet access and television services over a single pipeline and with sufficient bandwidth. However, to make this lucrative and cost-efficient triple play proposition a reality, service providers must first be able to monitor and manage the complexities of the far-reaching broadband network and service infrastructure, and ensure the same voice quality of service and IPTV quality of experience to which users are accustomed.
The broadband network is built from multiple interoperable domains ranging from the core network, through the edge, aggregation and access networks, to the content providers and the media head-end. Regardless of the content being provided and where on the network that content has to travel, service providers must understand and assure a subscriber’s experience when that subscriber connects to and uses the service provider’s broadband service.

The quality of the user’s experience (QoE) is influenced by the amount of service traffic across the broadband service delivery chain and the health and reachability of the resources in each domain of the network. Therefore, ensuring a high-quality broadband service experience requires that the service provider have end-to-end visibility from the core to the access networks (BRAS, DSLAM, WiMAX, CMTS and FTTx) and that the provider can holistically monitor the relevant performance indicators and QoE factors across the resources of the broadband network.
InfoVista’s VistaInsight® for Networks solution for network performance management, and its Broadband Knowledge Pack solution for BRAS, DSLAM, WiMAX, CMTS and FTTx monitoring, enable telecommunications providers to monitor the performance and capacity of their broadband network infrastructure and services from an end-to-end perspective. This end-to-end monitoring of network resources empowers providers to ensure that the broadband services they’re delivering, whether voice, video or Internet access, are always available and of the highest quality, just as their customers expect. It can also help the service provider to avoid stranded network capacity and resources, oversubscription, and unbalanced network utilization.
Key Features
InfoVista’s Broadband Knowledge Pack is an add-on module that interoperates with InfoVista’s award-winning VistaInsight® for Networks solution. Used in conjunction with VistaInsight for Networks, the Broadband Knowledge Pack provides:
- Advanced service modeling that understands the relationships between resources in a broadband service environment, the services they support, the customers subscribing to those services and their respective performance indicator
- The ability to holistically monitor a variety of key devices and domains and how they relate to a service
- Analysis/statistics on device and service utilization to identify trends, improve capacity planning and ensure faster time-to-market on revenue-generating broadband offerings, such as triple play services
- Monitoring and reporting on the broadband remote access server (BRAS), which provides routing of traffic from access devices, termination of PPP (Point to Point Protocol) sessions, and enforcement of broadband QoS (quality of service) policies on a per-flow and per-subscriber basis
- Deep visibility into the BRAS, DSLAM, WiMAX, CMTS and FTTx access domains via a wide range of customizable and workflow-efficient dashboards and reports that aid various user groups within a service provider organization (network operations, service operations, OSS architects, engineers and network planners)
- Consolidated administration, authentication and authorization (AAA) verification to ensure customer access and reduce end-user frustration
