Seamless content delivery

1999

Recent advances in network bandwidth and processing power of CPUs has led to the emergence of multimedia streaming frameworks, such as NetShow, Realvideo and Vxtreme. These frameworks typically rely on proprietary stream establishment and control mechanisms to access multimedia context. To facilitate the development of standards-based distributed multimedia streaming applications, the OMG has defined a CORBA-based specification that stipulates the key interfaces and semantics needed to control and manage audio/video streams.

Peer-to-peer (P2P) paradigm has provided a disruptive market opportunity to define cost-effective multimedia streaming services, but at the same time network-oblivious P2P applications have been posing substantial technical and social challenges on network efficiency, operator economics and user performance. While end users are concerned with quality upgrade, Internet content provider (ICP) considers more on service scale and Internet service provider (ISP) focuses on operating cost. In taming P2P for a more friendly large-scale application, this paper provides a framework of evaluating the P2P media streaming application performance from perspectives of all entities involved, that is ISP, ICP and end users. Three-level performance metrics are defined, essential concerns of each party are theoretically quantified and bottlenecks in affecting quality service are identified. In handling tussles between P2P performance against ISP traffic, system scale against cost and user QoS against Security, the authors present proposals in defining an unprecedented friendly and cost-effective P2P streaming application to achieve the ideal philosophy of 'more users ¼ better performance þ lower cost'. Based on the explorations in academy and industry, the authors envision that a large-scale streaming system will be built with a synergy of P2P and content distribution networks (CDN), and explore the feasibility of a general peer-server-peer (PSP) structure on the basis of our evaluation framework. With our analytical study and industrial deployment, this paper captures a certain essence of deploying large-scale P2P streaming application from a commercial and realistic point of view and suggests many avenues for addressing the emerging tensions between P2P application and network operators.

Future Media Internet will require to share and distribute high quality multimedia contents and services in a flexible, efficient and personalized way through dynamic and heterogeneous environments. One approach for fulfilling this is by means of taking advantage of P2P distribution techniques and the use of source coding techniques such as MDC and SVC. This paper discusses these issues based on the real experience of the authors and highlights their applicability in Future Media Internet initiatives in order to solve future challenges.

Multimedia applications over Internet are becoming popular due to the widespread deployment of broadband access. In conventional streaming architectures the client-server model and the usage of content distribution networks (CDNs) along with IP multicast were the most desirable approaches for many years. The client/server architecture, however, severely limits the number of simultaneous users in video streaming. The reason is the bandwidth bottleneck at the server side, since usually many clients request the content from the server. A CDN overcomes the same bottleneck problem by introducing dedicated servers at geographically different locations, resulting in expensive deployment and maintenance.

We propose a new architecture for on-demand media streaming centered around the peer-to-peer (P2P) paradigm.

Abstract—Peer to Peer networks (P2P) consist of a set of logically connected end-clients called peers, which form an application-level overlay network on top of the physical network. P2P solution facilitates contents/files sharing among Internet users in a fully distributed fashion. This paradigm is anticipated to resolve observed limitations in current centralized solution distribution and to significantly improve their performance. P2P networks are undergoing rapid progress and inspiring numerous developments.

Streaming media on the internet has experienced rapid growth over the last few years and will continue to increase in importance as broadband technologies and authoring tools continue to improve. As the internet becomes an increasingly popular alternative to traditional communications media, internet streaming will become a significant component of many content providers' communications strategy. Internet streaming, however, poses significant challenges for content providers since it has significant distribution problems. Scalability, quality, reliability, and cost are all issues that have to be addressed in a successful streaming media offering.
