Re: [ppsp] Progress on core tracker protocol?

The PPSP-TP base Tracker Protocol draft will be published before the end of June.
It does essentially what we had discussed during IETF 83.
The PPSP-TP Extended Tracker Protocol will bring all those more sophisticated features, and will be published afterwards (during July)

Cumprimentos/Regards,

This core protocol is the only requirement for a simple streaming service, along with the PPSP peer protocol. We refer to an upcoming Extended Tracker Protocol for more sophisticated features. For instance,  the exchange of meta information, content information, statistics reporting, etc.
