Protocol Specifications

Introduction

A phoenix query is introduced by the character $, and has three different parts :

Example query : $iinf server_core:phoenix|server_version:0.0.1
This is sent by the hub on a new connection : it gives to the client informations about the hub he is connecting to

• The first letter (i) identifies the recipient of the query :

Letter	Meaning	Description
h	hub	a message intended to the hub only
i	info	sent by the hub to a client
b	broadcast	sent by a client to the hub to be broadcasted to all connected peers (depending on the query, it will be first analysed by the hub
d	direct	a message sent by a client to a specific peer

• The three following letters (inf) identify the query

• Arguments for the query are made of key:value pairs seperated by a |. Keys are made of alphanumerical characters and _ only, and are case sensitive. Values can contain any utf-8 character except |, $ and newline \n.
