thanks a lot for the info! Although I have no current use for it,

it sounds pretty cool!

Here are some details...  : )

The purpose of the June reload coding session is to build a functioning P2PSIP stack based on RELOAD-04
(http://tools.ietf.org/html/draft-bryan-p2psip-reload-04).

For those of you who aren't familiar with P2PSIP or RELOAD, they replace the server-based rendezvous system of SIP with a peer-to-peer system based on a distributed hash table (DHT). Instead of having fixed servers, the UAs cooperate to provide a distributed registrar and rendezvous function. Roughly, the way this works is:

- When my UA starts up it joins the P2P overlay and stores its registration in the overlay.
- Each UA stores other people's registrations.
- When I want to make a phone call to "alice@xxxxxxxxxxx"

I use the overlay to rendezvous with here and form a direct connection which I can use to exchange SIP messages.

A key element of the design is that once the connection is set up between the UAs they just exchange ordinary SIP messages and phone calls proceed as usual. This is intended to allow easy integration
with existing SIP stacks and UAs.

At the end of the coding session we would like to have:

- A working RELOAD stack that can participate in the P2P network, including storing and retrieving data
 and routing messages.

 

Stretch Goals:

- A version of reSIProcate that's integrated with the RELOAD stack and can use it to REGISTER itself and make SIP calls.

The tasks we will be working on include:

- RELOAD stack
 + Connection formation between overlay peers
   . ICE
   . TLS/DTLS
 + Overlay maintenance (joining, leaving, updates)
   . Implementation of a single DHT (Chord)    
 + Message routing
 + Data storage and retrieval
 + Enrollment
   . Certificate server
+ reSIProcate
 + A new transport that can use RELOAD to set up
   connections and send SIP messages
 + The "SIP registrar usage" which stores registrations
   in the overlay

Just out of curiousity,

 

what are you guys currently working on in the P2P tree?
