Abstract The utilization of the networks in education system has become increasingly widespread in recent years. WebRTC has been one of the hottest topics recently when it comes to Web technologies for distributed systems as it enables peer-to-peer (P2P) connectivity between machines with higher reliability and better scalability without the overhead of resource management. In this paper, we propose a browser based, asynchronous framework of a P2P network using distributed, lookup protocol (Chord), NodeJS and RTCDataChannel; which is scalable and lightweight. The design combines the advantages of P2P networks for better and sophisticated education delivery. The framework will facilitate students to share course content and discuss with fellow students without requiring any centralized infrastructure support.

1 Introduction Several technologies like computing, database systems, networking, and web technology play an important role in the field of education technology. In the field of networking, several advancements have led to boom in online education. Beginning with traditional centralized systems, the trend has moved on to decentralized distributed systems. The use of such distributed systems promises several S. Vashishth (✉) ⋅ Y. Sinha ⋅ K.H.

advantages, such as higher reliability and better scalability. The peer-to-peer technology is superior to traditional client–server model because it does not require setting up a third-party server which makes it much more economical and practical in many situations. The peer-to-peer architecture offers the promise of harnessing the vast number of nodes connected to the network. Other significant features are redundant storage, permanence, efficient data location, anonymity, search, authentication, and hierarchical naming. Thus, this technology can be highly beneficial in supporting teachers and students to collaborate and share information together within a community. The contribution of this paper is design and successful implementation of a browser based, asynchronous framework of a P2P network using distributed, lookup protocol (Chord [1]), NodeJS, and RTCDataChannel. We have chosen Chord as it provides efficient lookup in a dynamic peer-to-peer system with frequent node arrivals and departures. Additional features can be layered on the top of the framework based on the practical usage to gain robustness and scalability. We have also illustrated some of
