Abstract

   This document concerns several significant operation issues of Peer-
   to-Peer Streaming Protocol (PPSP) usage, focusing on two basic modes:
   Leech mode and Seed mode. The related parameters setting for default
   PPSP scenario reference to tracker protocol and peer protocol
   respectively. Besides, the limitations and gaps of current PPSP
   system are identified at with the standpoint of satisfying PPSP
   requirements.

1. Introduction

   The Peer-to-Peer Streaming Protocol (PPSP) supports two kinds of
   streaming which include live and Video on Demand (VoD).  It is
   constitutive of two basic protocols: the PPSP peer protocol [RFC7574]
   and the PPSP tracker protocol [I-D.ietf-ppsp-base-tracker-protocol].
   Both of them are proposed from individual perspective based on PPSP
   structure. However, the end users are unnecessary to understand the
   whole procedure works and the parameters setting when combining
   above two mentioned protocol together in application. What's more,
   the potential limitations of current protocol should also be learnt
   and known to the community.

   The tracker protocol which in a request/response model handles the
   initial and periodic exchange of meta-information between trackers
   and peers. The peer protocol is supposed to run as a gossip like
