P2PSP is an open application-layer protocol for the real-time streaming of media content over a peer-to-peer overlay, where every peer is connected with each other following a push-based fully connected mesh scheme. This project was born of the necessity of teaching about computer networks in a more exciting way to students of computer science at University of Almería (a small university in the south of Spain) and … it worked!
In 2015 was the first time we participated as a mentoring organization in the GSoC program. We supervised three excellent students with great ideas. Their work has not only consisted of writing code but also thinking about new algorithms and researching about the problem in depth. We’d like to outline their projects.
NAT traversal via hole punching Set of Rules (Max Mertens)
Connection-ﬁltering-NATs are becoming increasingly frequent, and this is a situation that hinders the connectivity between peers. In this project Max worked in proposing and creating an extra functionality to handle those peers that are behind restricted-cone NATs and symmetric NATs. Max coded and tested his implementation in different scenarios.
Implementation of Content Integrity Set of rules for P2PSP (Ilya Shakirov)
Pollution attacks are a challenging security-related problem in peer-to-peer streaming platforms. We proposed two different theoretical strategies in order to detect a pollution attack in the context of the P2PSP live streaming system. In this project, Ilya coded the strategies, got statistical results and proposed improvements for the strategies.
