Analyzing client interactivity in streaming media
Cristiano Costa,Italo Cunha,Alex Fernando Borges,Claudiney V. Ramos,Marcus Rocha,Jussara M. Almeida,Berthier Ribeiro-Neto +6 more
TL;DR: This paper provides an extensive analysis of pre-stored streaming media workloads, focusing on the client interactive behavior, to identify qualitative similarities and differences in the typical client behavior for the three workload classes and to provide data for generating realistic synthetic workloads.
Proceedings ArticleDOI
Scalable media streaming to interactive users
TL;DR: This paper investigates alternative mechanisms for scalable streaming to interactive users by identifying a set of workload aspects that are determinant to the scalability of classes of streaming protocols and evaluating Bandwidth Skimming and Patching, two state-of-the-art streaming protocols.
Proceedings ArticleDOI
Can Peer-to-Peer live streaming systems coexist with free riders?
Joao Ferreira A. e Oliveira,Italo Cunha,Eliseu Cesar Miguel,Marcus Rocha,Alex Borges Vieira,Sérgio Campos +5 more
TL;DR: It is argued that denying service to uncooperative peers may not be the best long-term approach; the findings suggest that peer-to-peer live streaming can support unco cooperative peers.
Proceedings ArticleDOI
Network bandwidth requirements for optimized streaming media transmission to interactive users
TL;DR: An evaluation of the network bandwidth requirements for the interactive access optimized protocols, considering realistic workloads of different interactivity levels and canonical and real network topologies indicates that the optimizations also lead to a significant reduction in the average network bandwidth requirement.
Proceedings ArticleDOI
A behaviour model of the SopCast users
TL;DR: A characterization of the behavior of participants in SopCast, one of the most popular live transmission applications on P2P, is presented, which can be used as a basis for creating new protocols and generation of realistic synthetic loads for live broadcast on P1P.
