 h1. = Software Candidates Analysis 




 = 

 [[TOC(DesignXMPP, DesignXMPP_analysis, DesignXMPP_arch, DesignXMPP_im, , DesignXMPP_conference, DesignXMPP_presence, DesignXMPP_jingle,DesignXMPP_ft, depth=2)]] 

 In this phase the existing XMPP libraries will be analyzed and one will be chosen to be used throughout the project. 


 h2. 

 == Requirements 


 == 

  * Written in Python (C/C++ could also be used, but a wrapper would need to be written) 
 
  * Support for XMPP server and/or component 
 
  * Ability to use it with the current model used by SylkServer 
 ** 
   * Green threads 
 ** 
   * Callback based IO 


 h2. 

 == Software Libraries Evaluation 


 == 

 The following aspects were considered when evaluating a given library: 

 

  * Met requirements stated above 
 
  * Is it actively maintained? 
 
  * Example use cases 
 
  * Deployments in real-world scenarios 
 
  * Perceived complexity to integrate it with SylkServer architecture

 == Selected XMPP library 


 == 

 After analyzing candidate libraries *Wokkel* '''Wokkel''' was the chosen one for the following reasons: 

 

  * Implemented on top of Twisted, which makes integration with SylkServer straightforward 
 
  * Support for both component and XMPP server models, allowing for flexibility in implementation

  * Plugin architecture, 'subprotocols' implementing different XEPs 
 
  * Client and server component support 
 
  * XMPP server-to-server support (s2s) 
 
  * Designed to be used with Twisted (reactor model) 
 
  * Active development 


 h2. 

 == Selected SIP Library 


 == 

 SIP SIMPLE SDK http://sipsimpleclient.com used by SylkServer
