The updating content in v02 includes :

 

l  The local tracker can keep the content record of  local peers, at the same time when it forwards the  content update/registration information to tracker overlay. So, most content requests can be solved locally. 

l  Delete  the open issues in chapter 5, and decide to use local connection tracker to manage the status of the ppsp peers locally, as most peer requests are from local peers according to the algorithm mentioned above. If the peer status can not be found in local connection tracker, the request is forwarded to the tracker overlay, as each local tracker always registries its own address to a node on tracker overly, whose ID has a DHT mapping  with the PPSP peer. As the position of the peer status , which is also the peer’s connection node address, is always registered to the tracker overlay according to RELOAD.

l  A data kind for peerStatusIndex is defined.

 

As still some editorial errors, I’ll give a new version soon.

Thanks lin for updating the draft.

Maybe it’s better to give a brief introduction of the updating from -01 version to -02 version.

Hi All,

 

I’ve updated the distributed tracker draft for a while. Could you please give your comment on it ? Thanks!

 

http://tools.ietf.org/id/draft-xiao-ppsp-reload-distributed-tracker-02.txt

 

 

Abstract

 

This document defines PPSP tracker usages for REsource LOcation And

Discovery (RELOAD).  Although PPSP assumes a centralized tracker from

peer's point of view, the logical centralized tracker could be realized

by a cluster of geographically distributed trackers. In this draft, we

design distributed trackers system, which are organized by RELOAD. It

provides lookup service for file/channel indexes and Peer Status among

the distributed trackers.
