Due to the inefficient resource adjustment, the current p2p file sharing systems cannot achieve the balanced relationship between supplements and demands over the resources. In this case, the uploading bandwidth of the system node cannot be utilized efficiently and the overall system QoS is degraded. In this paper, an adaptive resource scheduling mechanism called push mechanism, is proposed, in which "proactive" strategies are provided to handle the unbalance supplement-demand relationship of some resource. Specifically, the system firstly forecasts which resource will becoming insufficient, then it pre-increase the uploaders over such resource so that the systemperformance is improved. Through numerical practical experiment in download platform of Tencent, it is proved that the proposed mechanism increases the downloading rate, saves the traffic on the server and optimizes the systemperformance.

Nowadays, Characteristics and user behavior of p2p file sharing system attract more attention. In this paper, we investigated system characteristics and user behavior in p2p file sharing system by using user log data of Maze system. We firstly confirmed that the users' request and the workload in p2p file sharing system have strong time characteristic. And then we analyzed composition of workload in p2psystem. Finally we pointed out that different users have different roles to contribute the workload and summarized the characteristics of these users online time in p2psystem.

In the existing works, system of addition-min fuzzy relation inequalities (FRIs) was introduced to model a peer-to-peer (p2p) filesharingsystem. For decreasing the network congestion, a minimax programming has been studied. However, in such programming, the different weights of the terminals (or peers) were not considered. In order to distinguish the different importance degrees of the terminals, we propose and investigate the weighted minimax programming problem in this work. A novel algorithm based on some discrete function-values is developed to obtain its optimal solution. Effectiveness of our proposed algorithms are further illustrated by some numerical examples.

With the rise of blockchain technology, peer-to-peer network system has once again caught people's attention. peer-to-peer (p2p) is currently being implemented on various kind of decentralized systems such as Interplanetary filesystem (IpFS). However, p2pfilesharing network systems is not without its flaws. Data stored in the other nodes cannot be deleted by the owner and can only be deleted by other nodes themselves. Ensuring that personal data can be completely removed is an important issue to comply with the European Union's General Data protection Regulation (GDpR) criteria. To improve p2ps privacy and security, we propose a monitorable peer-to-peer filesharing mechanism that synchronizes with other nodes to perform file deletion and to generate the file Authentication Code (FAC) of each IpFS nodes in order to make sure the system synchronized correctly. The proposed mechanism can integrate with a consortium Blockchain to comply with GDpR.

This paper proposes an efficient algorithm for p2p Me sharingsystems based on WiMAX mesh mode and Wi-Fi technologies. Wireless networks in our system are hierarchically divided into three layers: Wi-Fi based wireless local area networks under a subscriber station;the mesh network of subscriber stations under a base station;the network of base stations. file lookupprocedure may go through three steps: the requesting end host firstly looks up for the requested Me within it's neighbor end hosts under the same subscribe station;if fails, then it sends lookup messages to the nearest subscriber stations in the mesh network following to a changed dynamic source routing protocol;if both the steps fail, then the requesting end host searches the requested Me through the Chord-based base stations' overlay. By statistical analysis and simulations, we prove that our layered p2p Me sharingsystem can reduce the number of lookup messages in physical networks and prevent over expenses of precious bandwidth in wireless metropolitan area networks.
