In-network content caching has recently emerged in the context of Information-Centric Networking (ICN), which allows content objects to be cached at the content router side. In this paper, we specifically focus on in-network caching of Peer-to-Peer (P2P) content objects for improving both service and operation efficiencies. We propose an intelligent in-network caching scheme of P2P content chunks,...
Toward the P2P topology mismatch problem, we proposed a novel P2P service re-directing scheme and it is fully described in reference. Furthermore, we have successfully implemented this mechanism in EPON system. Experimental results show that our scheme can effectively reduce core network traffic, and evidently improve clients' downloading rate.
Emerging Peer-to-Peer (P2P) technologies have enabled various types of content to be efficiently distributed over the Internet. Most P2P systems adopt selfish peer selection schemes in the application layer that in some sense optimize the user quality of experience. On the network side, traffic engineering (TE) is deployed by ISPs in order to achieve overall efficient network resource utilization...
Because of user mobility, highly dynamic, error-prone wireless channels, the QoS control for mobile Peer-to-Peer (MP2P) streaming media has to face considerable challenges. Given to the advantages of policy management, we develop a policy-based QoS control (PBQC) architecture to provide QoS assurance dynamically and automatically in mobile network environment. And we also propose a MP2P streaming...
Layered P2P streaming has drawn great interest in mobile cellular network in recent years. As an important technology in this application, data scheduling plays a crucial role in achieving a high Quality of Service (QoS). The Rarest-First (RF) Scheme used in Layered P2P streaming has obtained a good performance in server load and throughput of peer nodes. However, it also brings some chanllenges,...
To combat the challenges(the mismatch between throughput and layer delivery ratio, the useless packets in high layers due to the loss of packets in low layers) brought by the layered encoding to data scheduling for P2P streaming in the mobile network, We propose a new data scheduling scheme, named MLayerP2P. The key idea of the MLayerP2P is: A 3-Stage Model is used to schedule the absent streaming...
SIP provides powerful capabilities for building audio conferencing services. However, the scalability for SIP-based telephony systems is mainly limited by both the capability of server and the availability of bandwidth. Based on the study of the SIP and P2P protocol, the paper proposes a pure hierarchical P2P architecture for SIP-based telephony systems. The architecture can dynamically increase the...
As a scalable paradigm for content distribution at Internet-wide scale, Peer-to-Peer (P2P) technologies have enabled a variety of networked services, such as distributed file-sharing and live video streaming. Most existing P2P systems employ non-intelligent peer selection algorithms for content swarming which greedily consume Internet bandwidth resources. As a result, Internet service providers (ISPs)...
This paper proposed a redirection scheme used in the broadband access network to optimize the transmission of p2p service. The excellent performance of the proposed scheme in decreasing the burden of the core network data is verified through the simulations with NS2.
Locality-based peer selection paradigms have been proposed recently based on cooperation between peer-to-peer (P2P) service providers, Internet Service Providers (ISPs) and end users in order to achieve efficient resource utilization by P2P traffic. Based on this cooperation between different stakeholders, we introduce a more advanced paradigm with adaptive peer selection that takes into account traffic...
Due to the fact that P2P applications have dominantly accounted for the entire Internet traffic, how to efficiently manage P2P traffic has become increasingly important. It has been recently proposed that the underlying network information can be shared between ISPs and P2P service providers in order to achieve efficient resource utilization, with the locality-based peer selection being a specific...
