Putting Broadband to work
Broadband value added services create value and loyalty, thus revenue.
Broadband carriers, access, and service providers initially focused on providing Internet Access. As competition and price pressure intensify, Providers are seeking to deploy IP-based value added services. Rapid Industry adoption of rich streaming media is being driven by an eco system of interested parties: Service providers, Advertisers, Broadcasters, Consumers and Carriers. This rapid conversion needs a new platform to manage, store, protect and distribute Broadband Content of all types (Games, Video, Music and Business Applications)
This document describes the needs and the solution for such a platform, empowering the new breed of horizontally layered providers of services. RAGAâ€™s platform was developed to uniquely address these concerns and offer and end-to-end solution for Broadband Content Delivery.
We regard Broadband as a powerful technology, potentially a â€œKiller Appâ€, because it can change and redefine our lifestyle, reshaping infotainment and the way we use our leisure. Broadband is a new infrastructure for numerous Infotainment services not possible before. It enables a Content Revolution in Entertainment (especially Music, Video and Games), education, Productivity and Communication.
During the last two years, the industry seems to understand this trend, and traditionally well-defined borders between separate types of operators seem to now blend. The Telecommunications Market is undergoing a vast convergence process. Different industries, having served in the past different sectors in the market, have now contributed, mostly thanks to technological advances, to the formation of the â€œInformation Societyâ€, where the general public accesses incommensurable quantities of all types of content and media:
Basic requirements to deliver Broadband Content
To fully realize the potential of a public network delivering Broadband On-Demand content to a â€˜segment of oneâ€™ user, Service intelligence is needed in the network, across all applications. To get a coherent and repetitive intelligence across many applications, the best solution is to host them on a single Middleware or Platform (which is what the RAGAâ„¢ framework is all about), which applies the intelligence to all content and applications. The service intelligence needs to ask each user:
Who are you?
What applications do you want to use?
Are you allowed to use it?
What class of service do you require?
How much are you willing to pay for that service?
The platform must then dynamically apply the necessary combination of security, performance, address management, and protocol functions. This user-oriented, session-aware service model requires that the platform support the following service intelligence functions:
User Authentication and Authorization â€“for secure access control
Security â€“ to ensure privacy and to protect content
CoS and QoS for tiered services and integration data, voice and video
Address management â€“ for guaranteed connection of the right content to the right user
Accounting â€“ fine-grained for usage-based billing
Customer Network management â€“ self provisioning and management
Content Delivery management â€“ by multiple content providers themselves
Trouble shooting â€“ end-to-end from the content provider, through the network, to the subscriber terminal
All these functions reside in the middleware layer connected to each and very user-application (Video-on-demand, Interactive Games, etc.) to provide a common interface for a simple, friendly and coherent user experience. Here is how the RAGAâ„¢ platfom logical design applies the layered approach:
At the end of the day, what we really need to deliver is the quality we take for granted in todayâ€™s PSTN, namely the â€˜ten commandmentsâ€™ of uninterrupted service: Availability, Affordability, Services, Security, Scalability, Simplicity, Connectivity, Performance, Flexibility, Ubiquity.
And because new IP services appear and evolve so rapidly, we need to do all that in a manner that minimizes time to market. A new service should be integrated, tested and be ready to launch in a matter of days, not months.
Another way to look at it is to realize we are providing LAN features over WAN. This makes the public network into an â€œIntranetâ€ for the authenticated subscribers. Once authenticated by their IP address and password, the subscribers get fast access to Broadband Content as if it was installed on their LAN. Their â€˜IT departmentâ€™ is the access provider, assuring trouble free availability of the service.
Who is the customer? Identifying business models.
Both content providers and consumers derive benefits from the content distribution. Consumers get high-quality full-screen video, games, Entertainment, and software. Content Providers get access to the mass of subscribers, in what is actually a new distribution channel. It makes sense to derive revenues from each of these users. The network operator may offer his services to multiple content providers, providing them with contracted storage space, access to itâ€™s backbone to distribute content, security and subscriber management. This warrants a fee.
As an example, all www sites owners with video elements may become customers. Think of a cinema chain in which websites you can review titles in a theatre near you and buy tickets. To preview a movie trailer, the visitor clicks on an icon, which today yields a small postage stamp size of jerky clip. What if this icon clicking instead only activates a link (metadata) to a broadband platform hosting the clips at the last mile, to stream full-screen quality trailer to the visitorâ€™s screen? Definitely a better surfing experience, differentiating this site from competitors.
Similarly, other players in the Content world can use this solution to provide Consumers direct access to their libraries, bypassing the Internet bottlenecks. Content Aggregators, Movie Studios, Karaoke producers, News Channels, Video-rental chains â€“ all will welcome a chance to provide direct, fast, high quality streaming of their content to the end users.
To enable this, the service provider must guarantee to the Content Provider:
An always-on availability, not the best-effort Internet standard, because they pay for it.
Security and protection for the content, so it not abused or stolen
Self-management of the Content Distribution by the Content Provider.
RAGAâ„¢ Content Delivery Framework â€“ the ideal solution.
The RAGAâ„¢ framework is a robust, carrier-grade, broadband platform designed exclusively to host, manage, and stream IP based content. Itâ€™s main features include:
High Throughput of over 2 Gbps
Scalability on-board, and to very large capacities through a distributed topology.
End-to-End management of content distribution from the content provider to the end user terminal
High Availability, no single point of failure.
Security to protect the platform and the content
Simply put, it is a combination of Caching, Hosting, and Smart IP QoS management to speed-up and move content from itâ€™s source, through the network backbone to the end user. This is done with security and address management, to assure delivery.
Managing Content Distribution by the Content Providers
A unique tool is provided, enabling content providers to automate and control distribution of their content via a simple, â€˜drag and dropâ€™ interface. The platform supports multiple concurrent content providers, each having a view of his contracted resources.
Content is first routed, through the network backbone, to a central RAGAâ„¢ server. From there, based on the policy defined by the Content Distributor, it is copied to any number of distributed platforms, using the broadband backbone of the network. This two-tier distribution paradigm allows a single broadcast of specific title from the content providers library, in a single session. The network takes care of the dissemination of the title. If such a paradigm was not possible, the content provider would need to create multiple sessions for the same title, sending it to each of the RAGAâ„¢ platforms in the network.
Personalization and user profiling
Each user can provision his/her profile and control preferences through a browser based interface.
Sophisticated APIâ€™s to integrate new user applications
APIâ€™s are built of atoms, providing simple interface commands to any external application. The advantage of this approach is faster-to-market launch of new services.
