Problem Statement of P2P Streaming Protocol (PPSP)

"We propose to develop an open peer-to-peer (P2P) streaming protocol named PPSP. This document describes the problems related to PPSP and outlines considerations that have to be taken in account when arriving at equitable solutions." ... this is the abstract but what's the actual scope of the problem statement?

• Proprietary protocols and an open PPSP
• Integrating cache and CDN into P2P streaming
• Integrating existing protocols into P2P streaming
• Mobility and wireless issue such as end to end communication is harder and limited bandwidth resource

The design issues include the choice of architecture and integration with existing protocols (i.e., legacy issues) such as RELOAD, ALTO, RTSP (and encapsulation), and edge devices (e.g., cache integration).
