Peer To Peer Networks

By Prof. Y. N. Singh | IIT Kanpur

Learners enrolled: 1018

This course will discuss about the concepts and architecture of peer to peer networks. These systems are built as an overlay on the existing Internet. The idea is basically to build the collaboration between user machines to implement services like telephony, distribute resilient file system, messaging system and other collaborative computing services. Such systems do not require server or need them in very limited fashion. The course will discuss at length the various DHT algorithms and their implementation complexities, the mechanisms to implement resilience using replication factor, efficiency of storage using universal file system where sharing the content does not create additional copies, mechanisms to ensure that nodes with different storage capacities can be used. Further architecture of Briahaspati4 an ongoing p2p system opensource project will also be discussed. The basics taught here will form the foundation of formation of user cloud systems.

Instructor bio

Prof. Y. N. Singh

IIT Kanpur

I did PhD from IIT Delhi in 1997. I was visiting faculty in University of Roorkee (Now IIT Roorkee) from Jan 1997 to July 1997 in Electronics and Computer Engineering Department, and faculty in Electrical Engineering Department, IIT Kanpur from July 1997 onwards. Currently, I am working as a Professor. I have research interests in Peer to peer networks, optical networks, digital switching systems. I have also been involved in opensource software development, and currently pursuing Brihaspati4 a peer to peer software system for supporting teaching and learning processes.
