In this paper we examine the performance of Peer-to-Peer (P2P) media streaming using Multiple Description Coding (MDC) and compare it with that of a Content Delivery Network (CDN). In both the approaches multiple servers simultaneously serve one requesting client with complementary descriptions. This approach improves reliability and decreases the data rate a server has to provide. We have impl...

With the advent of services and applications such as media streaming over the Internet, speed and reliability have become critical issues for users. Content delivery networks (CDNs) are (overlay) networks that are designed to distribute files to a set of clients. Through approaches such as replication of content at multiple servers (proxies) and redirection of user requests to closer servers, c...

The MediaWise project aims to expand the scope of existing media delivery systems with novel cloud, personalization and collaboration capabilities that can serve the needs of more users, communities, and businesses. The project develops a MediaWise Cloud platform that supports do-it-yourself creation, search, management, and consumption of multimedia content. The MediaWise Cloud supports pay-as...

{apathan, brobergj, raj}@csse.unimelb.edu.au ABSTRACT A Content Delivery Network (CDN) is expected to provide high performance Internet content delivery through global coverage, which might be an obstacle for new CDN providers, as well as affecting commercial viability of the existing ones. Peering of CDNs can be a way to allow cooperation between CDNs in a scalable manner and to achieve better...

T he Web's growth has transformed communications and business services such that speed, accuracy, and availability of network delivered content has become absolutely critical — both on their own terms and in terms of measuring Web performance. Proxy servers partially address the need for rapid content delivery by providing multiple clients with a shared cache location. In this context, if a req...

The increase of digital data between content's servers and clients in a network causes congestion problems when downloading big web contents including files, streaming media, etc. The problem becomes pronounced when a narrow bandwidth or unexpected termination of streaming services is appeared. Content Delivery Network (CDN) is introduced to overcome such problems by redirect client's...

Video-on-Demand (VoD) streaming services on the hybrid P2P-CDN architecture nicely balances high reliability contributed by CDN, and great scalability provided P2P. However, unmanageable trustless feature of P2P network can cause content piracy security threats to copyright holders users. To date, there has not been an adequate scheme based providing VoD in literature that resolves protection s...

Abstract: We have proposed an adaptive content distribution network (CDN), FCAN (Flash Crowds Alleviation Network), which changes its structure dynamically against a flash crowd, that is a rapid increase in server load caused by a sudden access concentration. FCAN in our preceding studies responds only to static content delivery. In this paper, we extend FCAN to alleviate flash crowds in video ...

HTTP Adaptive Streaming (HAS) refers to a set of novel streaming services that allow clients to adapt video quality based on current network conditions. Their use of existing HTTP delivery infrastructure makes them perfectly suited for deployment on existing Content Delivery Networks (CDNs). Nevertheless, this leads to some new challenges, related to the distribution of content across servers a...

The Web has evolved in the last decade from a mean to distribute content with marginal interest to a major communication media, where critical content and services are delivered to the users. This success was mainly driven by the concerns of content providers about the user-perceived performance of content delivery. When high availability, scalability, and performance are required, a common sol...
