Hi <div class="gmail_quote">2009/3/19 Manuel Alejandro Cerón Estrada <<a href="mailto:ceronman@gmail.com">ceronman@gmail.com</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hello. I want to participate in the Google Summer of Code this year. I have an Idea, but I'm not sure which mentoring organization would be the most appropriate. I would like to ask you what do you thing about this project and if you think is suited for GStreamer. I want to develop a streaming media system based on a peer-to-peer network. The motivation is to solve the problem of high bandwidth usage in current unicast media streaming servers based on a client-server architecture. Using a P2P network, where every node is both a server and a client is possible to distribute the bandwidth usage among the whole network. This approach is already used by file distribution systems like Bittorrent. I want to adapt the same idea for a live content media streaming system. Currently, there are various P2P media streaming systems. Only few of them are open source, but they are based on simple, inefficient, tree topology. I want to build a system based on mesh topology and swarming. There are various recent papers with architecture proposals for this. I'm working on this topic for my theses/graduation project. In my project I will work with simulations, but I thought that it would be great if I could implement a real system and test it. Summer of Code is a great opportunity for this, I participated the last year and I had a lot of fun. If you're interested I can show you the project proposal I send to my University, It's in Spanish, but I can translate it. It details the current state of the art of p2p streaming systems as well as architecture proposals for new systems. For this project, I want to use GStreamer, Python, C (if necessary) and Twisted. This tools are the same used by Flumotion, maybe I can work with that project in some way. Thanks in advance for your comments. [...]</blockquote></div> Fantastic idea. however, it seems that writing a P2P system by two bare hands in the summer is not a easy task. The core of P2P streaming system is the overlay network and data schedule algorithm, so use NS2/3 to make a simulation is also an operational way. as to me, since I am farmilar with TS and PS format, I want to write a plugin for Gstreamer in this summer, and I am reading the plugin write guide. Looking forward any potential mentor give some suggestion. zhao ting
