Introducing rtclite

We have attempted to unify our diverse Python based projects related to SIP, RTP, XMPP, RTMP, REST, etc., into a single theme of real-time communication (RTC). In particular, we have migrated the relevant source code from other projects to the new "rtclite" project after cleanup and refactoring. Moving forward, any new functionality related to Python implementations of real-time communication protocols and applications will be done in this new project.

Over the next few weeks, we will continue to evolve this project, migrate or fix issues/comments,  and deprecate the previous older projects. 

I will also write blog posts here  to introduce various specific modules and how they are used in real world in the new few weeks.

"Light-weight implementations of real-time communication protocols and application in Python

This project aims to create an open source repository of light weight implementations of real-time communication (RTC) protocols and applications. In a nutshell, it contains reference implementations, prototypes and sample applications, mostly written in Python, of various RTC standards defined in the IETF, W3C and elsewhere, e.g., RFC 3261 (SIP), RFC 3550 (RTP), RFC 3920 (XMPP), RTMP, etc."

We encourage all users of my open source projects to visit this new project, and if possible migrate your applications to use this new project.

Project ideas in P2P-SIP

This article lists some project ideas related to P2P-SIP. Feel free to contact me if you are a student interested in the project. For general networking and multimedia related project topics please visit http://myprojectguide.org

1. Survey of techniques for P2P VoIP: The project is a study project that surveys several existing P2P VoIP systems such as Skype, Gtalk, and several proposals in IETF P2P-SIP working group. The questions to answer are what are the best practices, what works, what doesn't, what has been implemented and tested, how do they compare with respect to scalability, robustness and security. Instead of comparing the whole systems, it is better to compare one function at a time, e.g., network maintenance, lookup, signup, etc. Clearly a critical and objective analysis is more useful than saying A is better than B.
2. Implement Reload: Implement the current version of IETF P2P-SIP WG internet-draft You may reuse the core p2p, dht and rfc3261 modules of the 39 peers project. The goal is to implement the core functions that allows incorporating external DHT algorithm, authentication as well as transport. I have a few suggestions to simplify the draft and hence the implementation. Language: Python.
3. P2P Simulator: Build a peer-to-peer network simulator in Python that implements various structured and unstructured algorithms. Related work includes p2psim, oversim and peersim. This project will build several modules to allow a developer to quickly put together an implementation of a P2P algorithm, view it graphically, and see the impact of various parameters. You should be able to support nodes behind NAT and firewall in your simulator, incorporate security and analyze the performance. Language: Python

Welcome to 39 peers!

I have launched an open-source project named "39 peers". From the web site:

"The 39 Peers project aims at implementing an open-source peer-to-peer Internet telephony software using the Session Initiation Protocol (P2P-SIP) in the Python programming language. The software is still incomplete -- especially the P2P part.

Peer-to-peer systems inherently have high scalability, fault tolerance and robustness against catastrophic failures because there is no central server and the network self-organizes itself. Internet telephony can be an application of peer-to-peer architecture where the participants locate and communicate with each other without relying on expensive or managed service providers. 39 peers project is an attempt to provide a open source and free-for-all peer-to-peer network targeted towards open standards based real-time communication.

The 39 peers project is developed for student developers and researchers to experiment with new ideas. It is written in Python scripting language. It supports open protocols such as IETF SIP and RTP. It is licensed under GNU/GPL license."
