“…There exist some systems, in which several approaches are combined such as AnySee [64], which possesses an underlay-aware mesh topology and deploys multi-path streaming, or PeerStreaming [42], which is based on a tree topology and utilizes ARQ and FEC. But more extensive research about different possible combinations together with an extensive simulation study should be performed to enable better comparisons regarding performance and resilience of the different combinations.…”

“…The major research question here is how to balance the amount of initial redundancy introduced into the stream with the expected amount of retransmissions. This aspect strictly depends on the media buffer size and the round trip time between peers [42]. For more information about retransmission strategies in P2P systems, please refer to [43,37,44,45].…”

Enabling resilient P2P video streaming: survey and analysis

Peer-to-Peer (P2P) techniques for multimedia streaming have been shown to be a good enhancement to the traditional client/server methods when trying to reduce costs and increase robustness. Due to the fact that P2P systems are highly dynamic, the main challenge that has to be addressed remains supporting the general resilience of the system. Various challenges arise when building a resilient P2P streaming system, such as network failures and system dynamics. In this paper, we first classify the different challenges that face P2P streaming and then present and analyze the possible countermeasures. We classify resilience mechanisms as either core mechanisms, which are part of the system, or as cross-layer mechanisms that use information from different communication layers, which might inflict additional costs. We analyze and present resilience mechanisms from an engineering point of view, such that a system engineer can use our analysis as a guide to build a resilient P2P streaming system with different mechanisms and for various application scenarios.

“…For example, certain BitTorrent implementation suggests [59] keeping a few unfulfilled requests on each connection in order to avoid a full round trip interval of empty delivery pipeline from the finishing of the download of one block to the beginning of the download of another block. PeerStreaming [60], an on-demand P2P streaming platform with pull mesh-based delivery, use a flow control strategy that keeps the pipeline from each sender filled to the same round trip interval between the request and the reply. BulletPrime [61] uses a XCP-like [62] congestion control scheme to maintain one waiting block in the sending TCP.…”

In both academia and industry, peer-to-peer (P2P) applications have attracted great attentions. P2P applications such as Napster, Gnutella, FastTrack, BitTorrent, Skype and PPLive, have witnessed tremendous success among the end users. Unlike a client-server based system, peers bring with them serving capacity. Therefore, as the demand of a P2P system grows, the capacity of the network grows, too. This enables a P2P application to be cheap to build and superb in scalability. In this paper, we survey the state of the art of the research and the development of P2P content delivery application. Using examples of the deployed P2P applications and research prototypes, we survey the best practices in P2P overlay building and P2P scheduling. We hope that the information may help the readers to build a reliable, robust P2P content delivery application.

Abstract-As the use of peer-to-peer (P2P) services for dis tributed file sharing has grown, the need for fine-grained access control (FGAC) has emerged. Existing access control frameworks use an all-or-nothing approach that is inadequate for sensitive content that may be shared by multiple users. In this paper, we propose a FGAC mechanism based on selective encryption techniques. Using this approach, the owner of a file specifies access control policies over various byte ranges in the file. The separate byte ranges are then encrypted and signed with different keys. Users of the file only receive the encryption keys for the ranges they are authorized to read and signing keys for the ranges they are authorized to write. We also propose an optional enhancement of the scheme where a file owner can hide location of the file. Our approach includes a key distribution scheme based on a public key infrastructure (PKI) and access control vectors. We also discuss how policy changes and file modifications are handled in our scheme. We have integrated our FGAC mechanism with the Chord structured P2P network. In this paper, we discuss relevant issues concerning the implementation and integration with Chord and present the performance results for our prototype implementation.
