“…Gnutella was developed after Napster to overcome its short comings [10][11][12]. Unlike Napster which is based on centralized server, Gnutella consists of fully distributed servers which consists of a hierarchical topology that connects each node to a super node called ultra-node, and each ultranode usually connect to more than 3 other ultra-nodes to make the network topology into hybrid P2P fashion.…”

File sharing is one of the most common uses in Peer-to-peer (P2P) networks and structured P2P systems, such as BitTorrent (BT), which may overcome the limitations of features such as improved scalability, efficiency, and deterministic data location. Recent research has attempted to reduce inter-ISP P2P traffic by including locality awareness into neighborselection strategies of popular P2P apps, which prioritize adjacent peers over distant peers when transferring data, reducing server bandwidth burden, and inter-ISP traffic expense. However, the locality awareness P2P exchanged, handled and coordinated by the network infrastructure to turn around traffic as nearest as possible to the end users was proposed for the passive optical network (PON) because of the large amount of bandwidth in only one single fiber. The PON offers many system architectures; in particular, the NG-PON2 with colorless ONUs, adopting time and wavelength division multiple access technology is often recognized as the best access network solution for simplifying network operation, lowering installation costs, and maintenance costs under control. Software-defined networking (SDN) has sparked interest in various fields as a viable research topic, promising better agility, improved automation, security, and lower capital and operating costs. Taking advantage of the SDN's OpenFlow protocol in NG-PON2, centralized control renders more flexible control over the BT traffic (P2P intratraffic) file sharing application provided by different ISPs. Finally, we evaluated our proposed scheme in real-time traffic share collected by Sandvine's report on 2020 despite the Covid-19 pandemic for different geographic regions, for example; Global, APAC, EMEA, and AMERICA.

A peer‐to‐peer (P2P) network is defined as a distributed network in which nodes with similar characteristics exchange data with others. Efficient data sharing in P2P systems is essentially faced with challenges due to uncertainties of erratic node failures and unreliable network connectivity. Data replication on multiple nodes can improve availability and alleviate latency. However, the number of created replicas and the corresponding location of these replicas need to be determined optimally. In this paper, a novel framework for data replication is proposed in P2P networks, in which optimal allocations are achieved based on the two objectives including the minimisation of delay and maximisation of hit rate of queries. The proposed model finds allocations that specify the number and location of each replica of existing files in the network based on two considered objectives. A multi‐objective technique based on the Non‐Dominated Sorting Genetic Algorithm II (NSGA‐II) algorithm is utilised to solve the proposed model and to extract non‐dominated Pareto‐optimal solutions of the allocations. Finally, one of the allocations of the obtained Pareto optimal set is applied to the network and the delay and hit rate of queries pertaining to this situation is compared with two models: i) initial model of the network, that is, the state where there is no replica of the files except the original version of the file, and ii) the random replication model to verify the efficiency of the presented method. All simulations in this paper have been done using C++ programming language.

Blockchain technology offers great properties such as scalability, decentralization, immutability, and security. These properties attracted many new fields such as healthcare, education, finance, and much more. This chapter proposes combining blockchain with big data technologies in order to provide a smart and efficient healthcare model. First, the authors propose to use the blockchain to save medical records (transactions) for patients on a large-scale system while preserving the privacy for patient. Blockchain can be used to keep track about each medical record for a patient. Since blockchains can save small amounts of data and since medical records can become very lengthy and complex to analyze, the authors propose to use big data technology in combination with blockchain. The big data technology can store large files and can handle heterogeneous files. Big data technology can apply sophisticated analysis on the data collected from blockchain.
