TAILIEUCHUNG - Intelligent IP Network Value-Added Service

Wireline network operators have increased available customer bandwidth with xDSL modems, DSLAMs and Broadband Remote Access Server (BRAS) systems. While this basic topology enables standard broadband service, most service providers want to expand their portfolios of broadband offerings to improve their competitive position, increase revenues and decrease operational expenses. | SG-1 Service Gateway Intelligent IP Network Value-Added Service Enhancements to Existing Broadband Networks od J Intelligent IP Network Value-Added Service Enhancements To Existing Broadband Networks Introduction Wireline network operators have increased available customer bandwidth with xDSL modems DSLAMs and Broadband Remote Access Server BRAS systems. While this basic topology enables standard broadband service most service providers want to expand their portfolios of broadband offerings to improve their competitive position increase revenues and decrease operational expenses. At the same time they realize that any enhancement to a network should leverage the existing architecture and easily integrate with it. Such enhancements require only incremental capital investment with minimal replacement of existing network elements. These enhancements also eliminate unnecessary operating expenses arising from changes in the network elements like operation and support management and billing and BRAS systems. Integration with the existing network including its operational processes is therefore a decisive factor in the choice of any new equipment and systems that enable value-added services such as bandwidth on demand and application awareness. These advanced services can be charged to the user with little or no impact on existing network elements and with minimal investment for the network operator. ADC s SG-1 Service Gateway meets these requirements since it is designed for simple and straightforward integration with a wide range of network elements and topologies. With its drop-in architecture the SG-1 takes the responsibility for service creation service enforcement and dynamic service management independent of the access network elements being used. The access network is responsible for access transmission and switching while service management and provisioning are handled in central or regional locations by the SG-1. This concept and topology are similar to a voice
