Design And Realization Of Control And Switch Hardware Platform For Access System Based On High Speed IP Bus

Telecommunications industry is undergoing an unprecedented confluence. The increasing competition in the market of telephony services is fierce. And telecommunication service providers are seeking new growth areas. In addition, telecom service providers are threatened by cable network operators and other new players (e.g. energy utility companies) rolling out Triple Play offerings combining video, broadband access, and telephony.IPTV (television service over IP networks) and Video on Demand (VoD) provided by telecom service providers is starting to compete with existing broadcasting services via terrestrial, satellite and cable networks. Getting IPTV right the first time is the key to winning business, retaining customers and building a sticky Triple Play service offering. To be successful into the future, telecom service providers have to quickly deploy revolutionary new service offerings such as Triple Play and IPTV.Adoption of broadband -- principally DSL -- is continuing to grow rapidly and as it does, service providers are challenged to offer competitive services that differentiate their marketplace offerings. The influx of competition offering integrated Internet, video/IPTV, and telephone services has created strong subscriber demand for Triple Play offerings, such as TV, VoD, and online gaming. The existing broadband network infrastructure, however, cannot support these services. The result has been a trend toward network convergence, requiring service providers to adopt cost-effective broadband access devices that integrate easily into the network infrastructure, and offer features such as Quality of Service (QoS) needed to ensure subscriber satisfaction.To maximize the market opportunities for broadband access solutions, however, it is important to build on industry-standard products, build in greater levels of intelligence, and employ hardware and software components that can not only scale, but also can be reused across multiple products.Many broadband trends -- including DSL growth, demand for better control over network assets, improved service management and control, and detailed monitoring and accounting -- are driving new requirements for DSL Access Multiplexers (DSLAMs) and other broadband access devices. The fact is, new services have more stringent requirements to support various service levels of video, voice, and data across hundreds of potential broadcast channels. Everything from VoIP and video communication, to interactive gaming and IP-based HDTV are on the table.These new services are demanding increasing port densities and line rates, as well as improved traffic policing, shaping, and tagging to support increased downstream...
