ACHARIYA COLLEGE OF ENGINEERING TECHNOLOGY DEPARTMENT OF COMPUTER SCIENCE AND ENGINEERING VIII - SEMESTER SEMINAR PEER TO PEER TECHNOLOGY By:Alex Jaison 20TD0503 PEER TO PEER NETWORK Introduction to Peer to Peer Network • Peer to Peer Network is a decentralized communication model where each participant has the same capabilities and responsibilities. • Users can directly share files, data, or resources without the need for a central server. • P2P networks are known for their scalability, as they can easily accommodate a large number of users. Types of Peer to Peer Networks • There are two main types of P2P networks: pure P2P networks and hybrid P2P networks. • In pure P2P networks, all participants have equal roles and responsibilities. • Hybrid P2P networks combine elements of centralized and decentralized systems for improved efficiency. Advantages of Peer to Peer Networks • P2P networks are resilient to single point failures, as the absence of a central server means there is no single point of failure. • Users can easily share large files or resources without overloading a central server. • Peer to Peer networks are cost-effective, as they eliminate the need for expensive server infrastructure. Disadvantages of Peer to Peer Networks • Security can be a concern in P2P networks, as it can be challenging to verify the identity of other users. • Quality of service may vary in P2P networks, as it relies on the resources and capabilities of individual participants. • P2P networks can be vulnerable to malicious activities such as malware distribution or copyright infringement. Applications of Peer to Peer Networks • P2P networks are commonly used for file sharing, such as BitTorrent for sharing large files. • Voice over IP (VoIP) applications often utilize P2P networks for connecting users for voice calls. • Content delivery networks (CDNs) leverage P2P technology to distribute content efficiently to users. Examples of Peer to Peer Networks • BitTorrent is a popular P2P file-sharing protocol used for distributing large files over the internet. • Skype, a widely used VoIP application, relies on P2P technology for connecting users for voice and video calls. • Blockchain technology, used in cryptocurrencies like Bitcoin, is based on a decentralized P2P network for transactions. Future Trends in Peer to Peer Networks • The adoption of blockchain technology is expected to revolutionize P2P networks by enhancing security and transparency. • Decentralized finance (DeFi) applications are leveraging P2P networks for peerto-peer lending and trading. • P2P networks are increasingly being used in Internet of Things (IoT) devices for direct communication and data sharing. Peer to Peer Networks and Cybersecurity • Secure communication protocols such as encryption and authentication are essential for protecting data in P2P networks. • Regular monitoring and auditing of P2P networks can help identify and mitigate security vulnerabilities. • Collaboration between cybersecurity experts and P2P network developers is crucial for enhancing network security. Challenges and Solutions in Peer to Peer Networks • Scalability can be a challenge in P2P networks with a large number of participants, but solutions like Distributed Hash Tables (DHT) can help manage the network efficiently. • Ensuring data integrity and authenticity in P2P networks can be addressed through cryptographic techniques like digital signatures. • Legal challenges related to copyright infringement and illegal activities in P2P networks can be mitigated through regulatory measures and user education.
